Read on to give yourself the best possible chance of finishing on July 20th, 2025.
The Etape du Tour offers amateur riders the opportunity to compete in an actual stage of the Tour de France, under closed-road conditions. This makes it the approximate equivalent of playing football on the hallowed turf of one of the world’s most famous stadiums. The event thus attracts many people who wouldn’t normally participate in a cycling race, but are keen to experience at least once what they see on their televisions in July every year. If you are one of these, you are right: it’s a fantastic, unforgettable experience! The Etape is always one of the mountain stages of the current year’s Tour, including iconic climbs and stunning scenery in a route that is already tough for the professionals and is extremely challenging for those unaccustomed to cycling in the mountains.
The 2025 route, from Albertville to a summit finish in La Plagne, includes a total of five significant climbs. Two of these, the col du Pré and the climb to La Plagne, are very tough. There are also four alpine descents, and there is very little flat road. Watch the video here for our “First Ride” presentation of the course.

Participation in the Etape du Tour is limited to 14,000 cyclists and, as usual, it sold out very quickly. The event attracts the best amateur riders from the world over, and competition is fierce. Only the best-trained cyclists can hope to finish anywhere near the podium. Simply to finish is an exploit to be proud of: literally thousands of riders abandon every year. Don’t let it happen to you!
Read on to learn how to train so that you have the best chance of success on the day.
Inexperienced riders should expect to take from 9 to 12 hours to finish the 131km and 4,500m of climbing between Albertville and La Plagne. Strong, well-trained amateurs will take from 6 to 8 hours. The winner will take around 4h30 to 4h40, and the fastest woman will probably finish 50 to 60 minutes later (in the top 200). Note that even for the best, this is twice the time it takes to finish a marathon. It is a challenging ride by any standards, and especially so if you are relatively new to cycling. Assuming that your goal is essentially to finish, without any particular concern for the time it takes, this is what it will take:

TL;DR (or in a nutshell, as we used to say): spend AS MUCH TIME AS YOU CAN doing the following:
In the remainder of the article, I’ll explain why and flesh out the details.
The best training plan is one that has been designed specifically for you. If you expect to take 10-12h to finish, you need a very different plan to someone who is aiming to finish in 6h. The closer to the front, the more like a race; the closer to the back, the more it becomes a pure endurance ride. The training is not the same.
In the rest of this article we provide a framework and a set of guidelines intended for someone whose objective is simply to finish the Etape. If you want to ride hard and set an ambitious time, read these guidelines instead.
The key principles behind a training plan aimed at finishing the Etape du Tour are:
Now that the principles are clear, in the next section we are going to explain how to create your training plan.

Our framework training plan begins on January 1st, giving you six and a half months to prepare for the event. It’s really important that you ride regularly throughout this period. If you can’t ride outside, you will have to compensate by riding indoors on a turbo trainer (it may be possible to hire a turbo trainer if you don’t want to buy one).
The framework includes three phases: Preparation, or Training to Train (January to March), Pre-Competition (April to early July) and Taper (the last two weeks before the Etape). Each phase is then broken down into 4-week cycles including 3 load weeks and 1 recovery week, with a target training load for each week. If you are over 50, instead of a 4-week cycle we recommend a 3-week cycle of 2 load weeks and 1 recovery week, because you will take longer to recover than a younger person.
It’s important to understand that such a structure is essentially arbitrary and takes no account of the total stress (life stress + training stress) you will be under on any particular day. If you feel stressed and tired, and/or if you have sore muscles, it would often be better either to take a very easy day or not to train at all until you have recovered. Hard training breaks you down: you only get stronger during recovery!
It’s best to take a pragmatic approach here. Pull out a calendar and mark off all your known constraints between today’s date and the Etape du Tour on July 20th. These might include work, travel, family commitments or anything else that will prevent or severely limit your training on any particular day. Next, go day by day and mark the amount of time you are ready to dedicate to training. Be realistic: there’s no point in starting out with a plan that will fail in the first two weeks. At this point, it’s a good idea to check for agreement with your partner and family: you might save a lot of misunderstandings and arguments later.
If your goal is simply to finish the Etape (as opposed to riding it as fast as possible), there’s no need to become single-minded, so long as you keep up a minimum, consistent level of training. It’s hard to give an exact figure that would apply to everybody, but you won’t go far wrong if you target 5h per week (on average) from now to the end of March, and then increase this to 8h per week (on average) for the last three months. Unless you are retired or have a different work pattern, most of your free time will be at the weekends. It’s not advisable, however, to ride only once or twice a week.
It obviously helps if you can ride to and from your workplace, but if this is not possible you will need to find another way to ride at least once mid-week. Doing it at home on a turbo trainer is fine.
Assuming you are working Monday to Friday, weekly schedules for hard and easy weeks during the Preparation phase (January – March) and the Pre-Competition phase (April to June) could look something like this:

The end result of planning this out, week by week, will be your own, personal and unique training plan, including the number of hours you plan to train day by day, every day between now and July 20th. This may seem like overkill but believe the specialists: it will give you the best chance of reaching your goal of earning your Finisher’s Medal at the Etape du Tour.
Remember the old adage: “Fail to plan equals plan to fail”!
Your plan is almost certain to need updating several times between now and July, as additional constraints such as family or work events get added. When this happens, adapt the plan accordingly. If the new constraint only affects a single day, you can either skip the planned training session altogether or re-plan it for another day. If the new constraint affects several days, it may make sense to re-plan the periodisation so that you train hard in the days leading up to the constraint and then recover during the constraint period when you can’t train anyway.

Now you have the time available to train on a day-by-day basis, you can plan your detailed workouts. The minimum time for a cycling workout is 30 minutes (anything less is best devoted to a Pilates or Yoga session intended to develop your mobility and flexibility). Based on your time available, place the following workouts as best you can on your schedule.
During the Preparation phase (from January to March) a typical high volume (hard) week should include the following workouts:
The suggested sessions are in order of priority. Do as many as you can but in this order. If you can only manage the first 4 sessions that’s fine. Still during the Preparation phase (from January to March) a typical low volume (easy) week should look like this:
These easy, recovery weeks are essential; do not be tempted to skip them. It is during these weeks that your body rebuilds and regenerates, becoming stronger. Hard training breaks you down: only recovery allows you to get stronger.
During the Pre-Competition phase (from April to June) a typical high volume (hard) week should include the following workouts:
Again, the suggested sessions are in order of priority. Do as many as you can but in this order. If you can only manage the first 5 sessions that’s fine. During the Pre-Competition phase (from April to June) a typical low volume (easy) week should look like much the same as in the Preparation phase:
Do not be tempted to skip these easy recovery weeks: they are essential.
During the Taper phase it is too late to build any fitness, so hard training is pointless. Your objective in this phase is to recover and taper your training in such a way that you maintain your fitness while eliminating your accumulated fatigue. You cannot just stop training because that will result in losing fitness.
Different people respond differently to a taper period and there are no hard-and-fast rules, but you won’t go far wrong if you reduce your training load (number of hours) by 25-30% for the second week of July and by as much again for the last week before the Etape.
Listen carefully to your body and if you feel tired train less. You will gain more by eliminating the accumulated fatigue than by forcing your unwilling body into yet another long ride.
The most important skills you need to finish the Etape du Tour successfully are descending (which is more technical as well as being much more dangerous than climbing); eating and drinking while cycling, and mental skills to keep you going when things get really tough. Let’s look at each of these in turn and how you can develop them during your training.

This is an important skill for several reasons. Firstly, experience tells us that most of the accidents will take place on the descents and will be caused by human errors. Secondly, there’s a lot of descending: almost as much as there is climbing Third, the roads are narrow and a good part of the descents are steep with tight and sometimes unpredictable turns. These can be very dangerous for inexperienced riders. Fourth, you will be surrounded by many other people of varying skill levels. The more confidence you have in your own skills the more you can avoid trouble. So it’s definitely worth the effort to learn. Like learning to ride a bike in the first place, or learning to ski, descending Alpine roads fast and safely is a skill that can only be learned with practice. This is obviously a bit of a challenge if you live far from the mountains, but there are some things you can do. These are your options if you live in a flat area:
There’s a good reason why the feed stations at the Etape du Tour are always very crowded: it would be impossible to finish the Etape without eating and drinking on the way. If you have to stop cycling every time you want to eat and drink, you will waste a considerable amount of time. It’s therefore important to learn to eat and drink while cycling, on varied terrain, including climbs and descents. You will have ample time to practice these skills during your long training rides.
Get used to carrying two water bottles and drinking from one or the other on a frequent basis. As a rule of thumb, you should be drinking 500ml (one small bottle or 2/3 of a large bottle) every hour, perhaps a bit less in cold weather, more in hot weather. On rides of less than 2h you don’t need an energy drink: water is fine. Over 2h it begins to be helpful to have an energy drink in one of your bottles in order to provide carbohydrates in liquid form. On rides over 3h it is important to do so.
There’s no need to eat anything on a ride of less than 2h, unless you feel hungry or weak. It is a good practice to have an energy bar in your pocket just in case. On rides exceeding 2h you should plan to eat at least 200 kcal per hour, starting early (so that you don’t get behind). It doesn’t really matter what you eat so long as it is predominantly carbohydrate and you can access it easily and eat while riding. Good choices include bananas, flapjacks, dried fruit (e.g. figs, apricots), biscuits, buns, new potatoes and of course commercial energy bars and gels. There are two places you can carry your food: either in your jersey pockets or in a special bag mounted on your top tube just behind the stem.
There will almost certainly be times on the Etape du Tour when you wonder why you are doing this and you have to battle an overwhelming desire to stop. For some people, this will first happen on the col du Pré (which has 7km straight at over 9%); for many others it will happen on the final climb to La Plagne, which is long and relentless.
If you follow our suggested training plan, you will automatically develop your mental strength as you increase the length of your rides and as you increase the difficulty of the interval sessions. But this may not be enough and you should spend some time thinking through what you will do during the event itself when all you want to do is stop. There are three main mental approaches that will help you to keep turning the pedals, all of which you should practice actively during your training:
Read here for more on mental strategies.
Don’t overthink this or worry about missing any one training session. Your goal is to finish the Etape du Tour, not to win the Olympics, and the training you need is correspondingly relatively simple. Simply put, spend as much time as you can doing the following:
All of the Alpine Cols coaches have ridden the Etape du Tour multiple times and know the challenge extremely well. We can help you prepare in two complementary ways:

]]>The post My training plan for 2025 first appeared on Alpine-Cols.
]]>For context, I will turn 66 in January 2025, so I am now fighting against the inevitable decline in muscle mass and joint flexibility which comes with age.
“A”: the Marmotte (175km and 5,000m+)
“B”: other sportives or Granfondos in the mountains, to be confirmed (these are typically around 125km and 2,500m+)
All these events have in common a considerable distance to ride in the mountains. At my level I expect to take around 5h at the shorter ones, and about 9h (total) at the Marmotte.
To perform well in these events you need high endurance, a high FTP/kg and high durability (the ability to repeat sweet-spot efforts on tired legs). My training objectives are therefore as follows:
But also,
I will be using the Alpine Cols framework training plan for the Marmotte, with the following adjustments:
| FTP: | 2 x intervals per week, typically short Z6 intervals since these have been shown to be most effective. |
| Durability: | Hard finish to long rides; big gear sessions for high torque. |
| Fat oxidation: | One long ride below LT1 per week, some fasted for first 3h. At least one ride per month should be >6h. |
| Economy: | Neuromuscular sessions such as: high cadence; low cadence, one-leg pedalling (especially through the autumn). e.g. 6 x 30’ single-leg then immediately one minute at 120rpm; spin-ups; sprints (high gear, near-standing start); cadence pyramids; 5’ low-cadence/high torque intervals |
I am following a cycling-strength programme with a US-based coach, who provides 3 strength sessions and 3 mobility/flexibility sessions per week. These sessions are well-designed, well-explained and progressive so all I need to do is to do the work.
I will be travelling in SE Asia for 17 days in November. This enforced break from cycling requires careful planning. Here’s how I intend to manage it:
Unfortunately, the harder one trains, the greater the risk of injury and sickness (due to a depressed immune system). If either happens, it’s essential to prioritise recovery over training. Better to take an extra two days to recover fully than to suffer a relapse and lose more valuable training time.
I use a daily measurement of resting heart rate (RHR) and heart rate variability (HRV), as well as a subjective evaluation of fatigue, muscle soreness and motivation as a guide to when my body is ready to accept hard training.

Time for an update! In the first part of this article I’ll describe my latest results and how they compare to my pre-accident performance; I’ll then analyse how I trained over the past 12 months and where I need to make changes for 2025.
Peak power test results:
My most recent 1’ and 5’ peak power numbers are about 10% below my best ever numbers (recorded 7-8 years ago), but comparable to my immediate Post-COVID/pre-accident numbers (when I wasn’t doing enough high intensity work).
Heart rate response:
The ratio of HR to power at a given, steady power output is a useful performance indicator. On this there is clear improvement since the start of the season: my average heart rate for one hour at 150-160W (around my LT1), and for one hour at 220W (sweet-spot, upper Z3/lower Z4) is in both cases about 10 beats lower than it was in February, and back to pre-accident levels.
Lactate test results:
My most recent lactate test was very pleasing, showing a significant improvement. I only tested for LT1, the first lactate threshold (the point at which lactate levels in the blood start to rise), since my training has been focused aerobic fitness. This has paid off with an increase in LT1 of 20W and 5bpm.
Competition results:
My principle objective in 2024 was the Marmotte Alps, on June 29. This was my fifth participation since 2016, making it a good reference for my performance. My best result was in 2019, when I managed 8h08. This year I finished in 8h52. The times are never directly comparable year to year due to different weather conditions (which were much worse in 2024), so let’s take a look at my power output on the climbs:
My second objective was the D’Vélos Lac d’Annecy sportive (123km, 2,800m) on August 25. My pacing strategy here was very successful, leading to a podium (3rd place) in my age category.
Conclusions: Good progress, especially in terms of aerobic fitness, but I still have a lot of work to do to get back to my pre-accident levels!
Let’s pick the story up where I concluded the previous article, on 8 September 2023. Things started well. A 7-day tour of Corsica with Alpine Cols clients brought my chronic training load (CTL – a measure of long-term training stress) to its highest level since my accident.
Unfortunately, I caught Covid (for the first time) on the return ferry. This, combined with other factors, drastically reduced my ability to train, especially with any intensity. I nevertheless finished 2023 with my second-highest volume ever, at 13,350km and 657 hours of cycling (12.6h/week). (See Table 1 for the statistics).
Looking at training stress, however, gives a different picture. (See PMC chart). The lack of intensity through the autumn and early winter, combined with a reduction in volume forced on me over Christmas and the early part of January resulted in my CTL dropping to its lowest level in 8 years (apart from the period immediately post-accident).

A two-week camp in the Canary Islands in late January and early February provided a useful boost, but work commitments kept preventing me from training consistently until early April. Once again a camp came to my rescue with another much-needed boost, and this time I was able to maintain progress until mid-July, when another setback, this time a throat infection, caused me to cancel several days of planned training and a race.
It’s not easy to maintain a steady ramp rate in one’s training load: everything has to go right!
A month later I’ve rebuilt my CTL to where it was in late June. It remains, nevertheless, at least 10 points below the level I would regularly reach for the 3 month period July to September pre-accident, suggesting that I may not be training enough to get back to my previous performance levels. Clearly, however, I am doing enough volume, so there must be an issue with the intensity. Let’s take a look at the evidence.
The following table gives the percentage of time I spent training in Z4 and above, based on both power and HR zones, from 2018 to 2024 (YTD).
| Year | % in Z4
and above (W) |
% in Z4
and above (HR) |
| 2017 | 20% | 12% |
| 2018 | 12% | 7% |
| 2019 | 15% | 8% |
| 2020 | 7% | 4% |
| 2021 | 5% | 2% |
| 2022 | 2% | 1% |
| 2023 | 5% | 1% |
| 2024 | 8% | 4% |
The table reveals a first step change in 2020, which cut the amount of intensity I was doing in half, and then a second step change in 2022 which almost eliminated it altogether. The first was due to the pandemic, which reduced my motivation for high intensity, and the second was due to my accident.
My goal since the accident was to focus first on rebuilding my endurance base – the multiple muscular and metabolic adaptations which underpin performance. To do this I trained extensively in low-mid Zone 2. Sometimes I did this before breakfast in a carb-depleted state, in order to increase my ability to burn fat at endurance pace.
I believe rebuilding the foundation was an essential first step and I should only add significant intensity once the base was strong enough.
I finally felt ready and started to rebalance my training in May this year, progressively reintroducing a good dose of intensity. Three months later, the results are starting to show. I will be continuing over the next few months, aiming to get back in 2025 to spending 12-15% of my training time in Z4 and above.
In my next article I will share the detailed changes I am making to my training plan for the coming season.

]]>The post Training Guidelines for the Etape du Tour first appeared on Alpine-Cols.
]]>
The Etape du Tour is a mass-cycling event for amateurs, organised on exactly the same route as one of the Tour de France stages. Since the Tour de France is one of the most-watched sporting events in the world, there is a huge desire to come and ride on the same roads as the professionals. The result is that the event sells out within hours and there are typically around 13,000 starters. The chosen route is invariably a tough mountain stage and a significant challenge. For all but the most experienced riders, finishing the Etape is an exploit to be proud of: many hundreds of riders abandon every year, more if the weather is bad.
The Etape du Tour is extremely prestigious and attracts many of the best Elite and semi-pro riders, as well as the best sportive and GranFondo riders from the world over. Needless to say, competition is fierce. Only the most dedicated and best-trained cyclists can hope to finish in the top thousand, let alone anywhere near the podium.
The Etape du Tour (version 2024) is 133km long and includes 4,600m of climbing, over four major climbs from Nice to a summit finish on the Col de la Couillole. The first is the col de Braus, 10km at 6.4%; the second is the col de Turini, 24km at 5.2%, the third the col de la Colmiane, 17km at 5.3%, and the last the col de la Couillole, 16km at 7.3%. With the exception of the last climb, the average gradients are misleading because the climbs are rather irregular.

The 2024 event is thus broadly comparable to the 2023 version (Annemasse to Morzine), which was 145km long and included 4,100m of climbing. The climbs are a little less steep, but the additional 500m of elevation will take a toll, as will the likely heat on the often south-facing slopes.
One thing that doesn’t change is the challenging nature of the descents. The descents from the col de Braus and the col de Turini in particular are long, fast and in places quite technical. There will be a large premium on descending skills.
Watch our video presentation of the 2024 Etape du Tour.
There were 11,791 official finishers in 2023. The exact number of starters is not made public but is probably in the region of 13,000, meaning that approximately 1,200 people were unable to finish. There is plenty of anecdotal evidence that many starters are inadequately prepared and indeed unaware how tough the event really is.
In order to help understand the performance requirements, the following tables provide the finishing times and average speeds for the first and last riders in each category at the 2023 Etape du Tour (beginning with the ladies):

We can expect broadly similar results in 2024.
The important number to look at is the average speed. Compare this to your average speed at any comparable event you have ridden and you will have a good idea of your likely place at the Etape. Do not make the mistake of comparing it to your average speed on a non-mountainous event: this will be very misleading, as it could easily be 10km/h higher.
Given the level of competition, “doing well” entirely depends on your frame of reference. For an Elite cyclist, it might mean finishing in the top 25. For a keen amateur, perhaps coming back for the 4th or 5th time, it may be possible to target a particular round-number place, such as the top 2,500. For others, the only sensible reference may be yourself. Can you finish, satisfied that you gave it your best shot – and enjoyed it? For others still, and especially for first-timers, simply obtaining the official Finisher’s medal is a significant achievement in itself.
Riders who do best at the Etape will have the following characteristics, compared to others in their category:
Each criterion is important and any weaknesses will undermine your performance.
Before working on your personal training plan, take the time to make a realistic analysis of your current abilities against this list to identify your strengths and limiters.
To obtain your best performance you should not only continue to develop your strengths, but also to work on your limiters, at least to the point where they no longer handicap you.
As an example, if descending is a limiter for you, you might easily lose 5-10 minutes on each descent and be overtaken by hundreds of people. Apart from the risk of accident, the cumulative effect will be even worse because you will lose touch with the people you were riding with and drop back several groups each time. The result could easily add up to a 30 minute deficit by the end. This is a shame, because descending fast and safely is a skill that can be learned and has almost no extra energy cost!
There is no such thing as a standard training plan for the Etape. It should be obvious that a 23 year-old Elite rider with the goal of finishing in the top 10 will need a different plan to a 60 year-old first-timer whose only goal is to finish. However the same argument applies across the board. The best training plan for you is one that has been designed with your unique strengths, limiters, objectives, context and constraints in mind, and is constantly adapted for you when things change (as they inevitably do).
This is why we are not providing a standard plan. The “plan” we propose below is in fact a set of guidelines and a framework for you to adapt to your own needs. Our goal is to give you the means to think carefully about the process and take responsibility for your own preparation.
HOWEVER, this is not a book and we cannot possible explain here all the nuances and individual variations inherent in the training process. We therefore strongly encourage you to use this document as an aide-memoire to what might be important, but then either to do your own research into how to apply it, or to find a coach to help you.
Our guidelines and framework are aimed at the “keen, self-coached amateur” who will finish somewhere in the middle of the pack, since this represents at least 60% of the participants.
If your only goal is to finish, you can simplify the process and focus mainly on developing your aerobic capacity by progressively increasing your weekly distance and climbing. If your bike-handling and descending skills are not great, you are at a high risk of an accident and so you must devote time to improving these vital skills. Road cycling, at speed and in groups, especially in the mountains, is a highly technical and skilful sport and it takes many hours of deliberate practice before you can participate safely in an event such as the Etape.
The key principles behind a training plan to “do well” at the Etape are, in rough order of priority for the keen, self-coached amateur:
If you are a new, inexperienced cyclist, developing your technical skills is the #1 priority!
Our framework training plan begins on January 1st, giving you six months to prepare for the event.
A key assumption is that you will continue to ride regularly on the roads throughout the period. If this is not possible, you will have to compensate by doing long rides on a turbo trainer and ideally by joining a training camp in the early part of the year in a warm-weather location such as southern Spain or Portugal, Mallorca or the Canary Islands.
Alpine Cols is running three coaching camps in 2024 which could help you. All have a strong focus on improving the skills and technique you need at the Etape. The first is in the Canary Islands 27 Jan to 3 Feb; the second is our GF Vosges camp 15-19 May, and the third is our special Etape du Tour camp 9-15 June. This last camp is totally designed around preparation for the Etape and includes riding the full route (over two days). Alpine Cols coaching camps
Our framework training plan includes three phases:
Each phase is then broken down into 4-week cycles including 3 load weeks and 1 recovery week, with a target training load for each week. If you are over 50, consider adopting a 3-week cycle of 2 load weeks and 1 recovery week.
It’s important to understand that such a structure is essentially arbitrary and takes no account of the total stress you will be under (life stress + training stress) on any particular day. If you feel very tired, have sore muscles, your Resting Heart Rate (RHR) is unusually high and your Heart Rate Variability (HRV) is unusually low, you should either take a very easy day or not train at all until you have recovered. Research has shown that training when you are stressed (low HRV) provides little or no benefit and may even be harmful. Read here for more on how to use HRV to guide your training.
Remember that hard training breaks you down: you only get stronger during recovery!
The key objectives here for most riders are to (re-)accustom your body to training 8-12 hours per week, to build a strong aerobic base, and to use high intensity interval sessions to develop threshold power and short-term muscular endurance. If you are a new cyclist and/or your goal is only to finish, it is more important to spend time on your bike than to worry too much about intervals.
The training intensity distribution during this phase should be Polarised, meaning 80%-90% of your training should be at low intensity and only 10%-20% at high intensity. The percentage breakdown is calculated on the basis of the number of hours in the workout, not the actual time spent at high intensity. Thus, a typical high-intensity interval session will last an hour (and should be counted as such) even if the actual high-intensity time doesn’t exceed 10-20 minutes. If you add 5-10 sprints to a 4-hour low-intensity outing, count 3 hours at low intensity and 1 hour at high intensity.
You should avoid extensive training at medium intensity (in Z3, often called Tempo or in low Z4, often called Sweet-Spot), because at this time of year it creates too much fatigue for too little benefit.
Riding slowly may sound incredibly boring and it certainly takes some adaptation, not least in your attitude and mindset. Read here for tips on how to help the time pass on long slow rides.
If you are unable to ride outside you will have to do long sessions on your turbo trainer. Read here for suggestions on how to make these more tolerable.
Adjust your food intake to your energy expenditure: eat more, especially carbs, on high load days and during high load weeks, and cut back sharply on the carbs during easy days and recovery weeks. Make sure you eat plenty of protein (1.8g/kg of body weight is a good target during training). Keep an eye on the scales to be sure that any weight loss is slow and progressive: the priority at this stage is to fuel your training!
Obviously each food item should be as high quality and as natural as possible. Avoid processed and especially industrial foods. Read here for more on nutrition while training.
You may not be used to off-the-bike training. Nevertheless, it can have a significant impact on your performance, especially as you get older. To cycle faster, you need to push harder on the pedals, which means you need not only stronger leg muscles but also greater core strength to stabilise and channel the extra force. The best way to strengthen your muscles is off the bike, using appropriate exercises and good technique.
If you are new to this, err on the side of caution to limit the risk of injury. Good exercises to begin with include squats, lunges, planks, bridges and roll-downs. All of these require correct technique to be beneficial. Once you’ve learned good technique you can do this at home.
The key objectives during the Pre-Competition phase are (1) to increase the training load to 15 hours per week or more, (2) to reinforce your aerobic base, (3) to improve your climbing at race pace and (4) to improve your general race readiness.
The training intensity distribution should now switch to Pyramidal. You should still train for 70% of the time at low intensity but you should now introduce medium intensity training (Z3 tempo and low Z4 sweet-spot) for 20% of the time, while maintaining 10% at high intensity. Your training thus becomes more race-specific as you get closer to the event. In practice it means adding tempo or sweet-spot sessions to one or two rides per week while maintaining one ride per week focused on high intensity work.
The key objective is to eliminate fatigue without losing fitness. You want to arrive on the start line the fittest you have ever been, but also super-fresh and thus able to race hard and ensure your qualification.
Progressively reduce your training volume by at least 50%. For example, if you have been riding 15h per week, you might bring it down to 10h in the second-to-last week and no more than 7h in the final week. If in doubt, do less. It’s too late to make any difference to your fitness and it’s far more important to eliminate the accumulated fatigue.
Ideally, you should arrive in Nice at least 2-3 days before the start. The earlier, the better. Do a couple of short rides to spin the legs but nothing strenuous. Some people find it beneficial to do a few short efforts at high intensity on the day before a race, e.g. 5’-10’ in Zone4, 1’-2’ in Zone5, but this doesn’t work for everybody. If you are not sure if it works for you, better not to risk it.
The need for sleep, good quality nutrition and minimum stress are even more acute during the taper. The advice is the same as for the Pre-Competition Phase. The better you can plan to sleep well, eat well and avoid stress, the better off you will be.

[1] Ideally, you should determine LT1 via a lactate test. Failing this, you can estimate it by paying very careful attention to your breathing while starting at a very low intensity and increasing slowly. Your LT1 will be the point where you first feel the need to start breathing more deeply. For the majority of people, LT1 will be in the range 60-65% of FTP or 60-65% of HRmax

]]>The post Recovery from a serious accident, Part 2 first appeared on Alpine-Cols.
]]>In this article I pick up the story where I left off and write about my ongoing efforts to recover my previous level. The story illustrates the effects of detraining and the very considerable amount of time and patience required to get back to one’s previous level, particularly as one gets older (I am now 64).
I concluded the article in November as follows:
“During the next three months I intend to stabilise my average training load at around 15-16 hours per week (including cycling, swimming, walking and strength workouts).
My goal is to recover and even improve my pre-accident aerobic condition. This will mean a high volume of low-intensity work combined with a small amount of high-intensity to recover some anaerobic fitness through the winter period, and then adding more event-specific sweet-spot and high-intensity work in the spring and early summer.”
I ended, somewhat optimistically, by stating: “If all goes well, by late spring of 2023 I should be back to normal!”
My training effectively restarted in early November. For the first three months I averaged 12.7 hours per week, increasing this to 15.9 in the next three months and 16.3 in the last three months. There was a lot of variation however, with the biggest week at 35 hours and the smallest at 7.4 hours.
Note that I didn’t record short walks, swimming, stretching sessions or other non-specific movement during the day.
The Performance Management Chart (below) shows my steady increase in load, with the variation between load and deload periods standing out clearly.
You can see the response of my nervous system to the training load (and other sources of stress) in the HRV chart below. Interestingly, this shows increased HRV (which is good) whenever I am able to ride for 4 hours per day or more over a period of several days. Looks like I need to make this a daily habit!
Throughout this period my goal was above all to rebuild a strong aerobic base. As a result, I did the vast majority of my training in Zones 1 and 2. I tried to keep it very close to LT1, the first lactate threshold (also called the aerobic threshold). This is believed to be the most effective intensity to build aerobic endurance and fat-burning capacity, especially during long rides.
Beginning at 2 hours, I increased the duration of my rides progressively and whenever possible, doing the first 3 hour rides in December. I managed a 6 hour ride in February, followed by several more in April and May, and then added a couple of 7 hour rides and finally a 10 hour ride at the Marmotte in July.
On average I did one high or higher intensity ride every 10 days or so. Some were unstructured, tempo efforts, some were structured intervals in Z4, Z5 or Z6. I rode in only two competitive events, the Marmotte on June 25 and a local sportive on July 30.
My training metrics showed steady improvement, with my HR/power ratio coming down significantly over the year. It is now back to where it was pre-accident, suggesting that I’ve regained pretty much all of my aerobic fitness.
My critical power and power at VO2max are still some 25-30W (~10%) below my pre-accident levels. This is not surprising given the low emphasis I placed in high intensity training. I am now increasing the frequency of these workouts to at least one per week and expect to make rapid gains at the higher end.
My goals at the Marmotte were to get my nutrition right, to enjoy it and to finish. There was a major course change this year meaning that times can’t be compared with previous years, which is a pity. I normally finish around the 1000th place; this year I was 1904th. I was clearly under-trained for so much climbing and suffered particularly on Alpe d’Huez.
The local sportive was much shorter 1t 120km and 2,200m, so I decided to deliberately start out too hard and see when I would crack. This turned out to be after about 3 hours. I eventually suffered quite severe cramps and the finish was painful. No surprises: my durability is clearly way down due to the small amount of high intensity work I’ve done.
At the age of 64 it’s reasonable to ask if I will ever recover the level I had when I was 62. I don’t know the answer to that yet, but I’m giving it my best shot. The core of my training from hereon is:
Let’s see where it takes me.

]]>The post This is what it takes to finish the Etape du Tour first appeared on Alpine-Cols.
]]>If you are a first-timer at the Etape, and a relatively inexperienced cyclist, this training guide is for you. Follow it carefully and you will give yourself the best possible chance of reaching the finish line on July 9th.
The Etape du Tour offers amateur riders the opportunity to compete in an actual stage of the Tour de France, under closed-road conditions. This makes it the approximate equivalent of playing football on the hallowed turf of one of the world’s most famous stadiums. The event thus attracts many people who wouldn’t normally participate in a cycling race, but are keen to experience at least once what they see on their televisions in July every year. If you are one of these, you are right: it’s a fantastic, unforgettable experience!
The Etape is always one of the mountain stages of the current year’s Tour, including iconic climbs and stunning scenery in a route that is already tough for the professionals and is extremely challenging for those unaccustomed to cycling in the mountains. The 2023 route includes four medium-sized climbs and two major ones, with as many descents. There’s relatively little flat road. Watch the video here for our presentation of the course.
The Etape du Tour is limited to 14,000 participants and always sells out very quickly. The event attracts the best amateur riders from the world over, and competition is fierce. Only the best-trained cyclists can hope to finish anywhere near the podium. Simply to finish is an exploit to be proud of: literally thousands of riders abandon every year.
Don’t let it happen to you!
Read on to learn how to train so that you have the best chance of success on the day. Watch here for a video presentation.
Inexperienced riders should expect to take from 9 to 12 hours to finish the 152km and 4,000m of climbing between Annemasse and Morzine. Strong, well-trained amateurs will take from 6 to 8 hours, while the winner will take around 5h15 to 5h30. Note that even for the best, this is twice the time it takes to finish a marathon.
It is a challenging ride by any standards, and especially so if you are relatively new to cycling. Assuming that your goal is essentially to finish, without any particular concern for the time it takes, this is what it will take:
So let’s see how to prepare for this.
The best training plan for you is one that has been designed specifically for you. If you expect to take 10-12h to finish, you need a very different plan to someone who is aiming to finish in 6h. The closer to the front, the more like a race; the closer to the back, the more it becomes a pure endurance ride. The training is not the same.
Since we don’t know you, we can’t give you a detailed training plan. What we can do is provide a framework and a set of guidelines for you to adapt to your needs.
The key principles behind a training plan aimed at finishing the Etape du Tour are:
Now that the principles are clear, in the next section we are going to explain how to create your training plan.

Our framework training plan is attached as the last two pages of these Guidelines. You can download it here.
It begins on January 1st, giving you six months to prepare for the event. It’s really important that you ride regularly throughout this period. If you can’t ride outside, you will have to compensate by riding indoors on a turbo trainer (it may be possible to hire a turbo trainer if you don’t want to buy one).
The framework includes three phases: Preparation, or Training to Train (January to March), Pre-Competition (April to June) and Taper (the last two weeks before the Etape). Each phase is then broken down into 4-week cycles including 3 load weeks and 1 recovery week, with a target training load for each week. If you are over 50, instead of a 4-week cycle we recommend a 3-week cycle of 2 load weeks and 1 recovery week, because you will take longer to recover than a younger person.
It’s important to understand that such a structure is essentially arbitrary and takes no account of the total stress (life stress + training stress) you will be under on any particular day. If you feel stressed and tired, and/or if you have sore muscles, it would often be better either to take a very easy day or not to train at all until you have recovered.
Hard training breaks you down: you only get stronger during recovery!
It’s best to take a pragmatic approach here. Pull out a calendar and mark off all your known constraints between today’s date and the Etape du Tour on July 9th. These might include work, travel, family commitments or anything else that will prevent or severely limit your training on any particular day.
Next, go day by day and mark the amount of time you are ready to dedicate to training. Be realistic: there’s no point in starting out with a plan that will fail in the first two weeks. At this point, it’s a good idea to check for agreement with your partner and family: you might save a lot of misunderstandings and arguments later.
If your goal is simply to finish the Etape (as opposed to riding it as fast as possible), there’s no need to become single-minded, so long as you keep up a minimum, consistent level of training. It’s hard to give an exact figure that would apply to everybody, but you won’t go far wrong if you target 5h per week (on average) from now to the end of March, and then increase this to 8h per week (on average) for the last three months.
Unless you are retired or have a different work pattern, most of your free time will be at the weekends. It’s not advisable, however, to ride only once or twice a week. It obviously helps if you can ride to and from your workplace, but if this is not possible you will need to find another way to ride at least once mid-week. Doing it at home on a turbo trainer is fine.
Assuming you are working Monday to Friday, weekly schedules for hard and easy weeks during the Preparation phase (January – March) and the Pre-Competition phase (April to June) could look something like this:
The end result of this work will be your own, personal and unique training plan, including the number of hours you plan to train day by day, every day between now and July 9th. This may seem like overkill but believe an experienced coach: it will give you the best chance of reaching your goal of earning a coveted Finisher’s Medal at the Etape du Tour!
Remember the old adage: “Fail to plan equals plan to fail”.
Your plan is almost certain to need updating several times between now and July, as additional constraints such as family or work events get added. When this happens, adapt the plan accordingly. If the new constraint only affects a single day, you can either skip the planned training session altogether or re-plan it for another day. If the new constraint affects several days, it may make sense to re-plan the periodisation so that you train hard in the days leading up to the constraint and then recover during the constraint period when you can’t train anyway.

Now you have the time available to train on a day-by-day basis, you can plan your detailed workouts. The minimum time for a cycling workout is 30 minutes (anything less is best devoted to a Pilates or Yoga session intended to develop your mobility and flexibility). Based on your time available, place the following workouts as best you can on your schedule.
During the Preparation phase (from January to March) a typical high volume (hard) week should include the following workouts:
The suggested sessions are in order of priority. Do as many as you can but in this order. If you can only manage the first 5 sessions that’s fine.
Still during the Preparation phase (from January to March) a typical low volume (easy) week should look like this:
These easy, recovery weeks are essential; do not be tempted to skip them. It is during these weeks that your body rebuilds and regenerates, becoming stronger. Hard training breaks you down: only recovery allows you to get stronger.
During the Pre-Competition phase (from April to June) a typical high volume (hard) week should include the following workouts:
Again, the suggested sessions are in order of priority. Do as many as you can but in this order. If you can only manage the first 5 sessions that’s fine.
During the Pre-Competition phase (from April to June) a typical low volume (easy) week should look like much the same as in the Preparation phase:
Do not be tempted to skip these easy recovery weeks: they are essential.
During the Taper phase it is too late to build any fitness, so hard training is pointless. Your objective in this phase is to recover and taper your training in such a way that you maintain your fitness while eliminating your accumulated fatigue.
You cannot just stop training because that will result in losing fitness.
Different people respond differently to a taper period and there are no hard-and-fast rules, but you won’t go far wrong if you reduce your training load by 25-30% for the last week of June and by as much again for the first week of July.
Listen carefully to your body and if you feel tired train less. You will gain more by eliminating the accumulated fatigue than by forcing your unwilling body into yet another long ride.
The most important skills you need to finish the Etape du Tour successfully are descending (which is more technical as well as being much more dangerous than climbing); eating and drinking while cycling, and mental skills to keep you going when things get really tough. Let’s look at each of these in turn and how you can develop them during your training.
Photo: Sportograf
This is an important skill for several reasons. Firstly, experience tells us that most of the accidents will take place on the descents and will be caused by human errors.
Secondly, there’s a lot of descending: almost as much as there is climbing
Third, the roads are narrow and a good part of the descents are steep with tight and sometimes unpredictable turns. These can be very dangerous for inexperienced riders.
Fourth, you will be surrounded by many other people of varying skill levels. The more confidence you have in your own skills the more you can avoid trouble.
So it’s definitely worth the effort to learn. Like learning to ride a bike in the first place, or learning to ski, descending Alpine roads fast and safely is a skill that can only be learned with practice. This is obviously a bit of a challenge if you live far from the mountains, but there are some things you can do.
These are your options if you live in a flat area:
There’s a good reason why the feed stations at the Etape du Tour are always very crowded: it would be impossible to finish the Etape without eating and drinking on the way. If you have to stop cycling every time you want to eat and drink, you will waste a considerable amount of time. It’s therefore important to learn to eat and drink while cycling, on varied terrain, including climbs and descents.
You will have ample time to practice these skills during your long training rides. Get used to carrying two water bottles and drinking from one or the other on a frequent basis. As a rule of thumb, you should be drinking 500ml (one small bottle or 2/3 of a large bottle) every hour, perhaps a bit less in cold weather, more in hot weather.
On rides of less than 2h you don’t need an energy drink: water is fine. Over 2h it begins to be helpful to have an energy drink in one of your bottles in order to provide carbohydrates in liquid form. On rides over 3h it is important to do so.
There’s no need to eat anything on a ride of less than 2h, unless you feel hungry or weak. It is a good practice to have an energy bar in your pocket just in case. On rides exceeding 2h you should plan to eat at least 200 kcal per hour, starting early (so that you don’t get behind). It doesn’t really matter what you eat so long as it is predominantly carbohydrate and you can access it easily and eat while riding. Good choices include bananas, flapjacks, dried fruit (e.g. figs, apricots), biscuits, buns, new potatoes and of course commercial energy bars and gels. There are two places you can carry your food: either in your jersey pockets or in a special bag mounted on your top tube just behind the stem.
There will almost certainly be times on the Etape du Tour when you wonder why you are doing this and you have to battle an overwhelming desire to stop. For some people, this will first happen on the steep section of the col de la Ramaz (the penultimate climb); for many others it will happen on the col de Joux Plane, which is long and relentlessly steep.
If you follow our suggested training plan, you will automatically develop your mental strength as you increase the length of your rides and as you increase the difficulty of the interval sessions. But this may not be enough and you should spend some time thinking through what you will do during the event itself when all you want to do is stop. There are three main mental approaches that will help you to keep turning the pedals, all of which you should practice actively during your training:
Read here for more on mental strategies.
Don’t overthink this or worry about missing any one training session. Your goal is to finish the Etape du Tour, not to win the Olympics, and the training you need is correspondingly relatively simple. In a nutshell, spend as much time as you can doing the following:
All of the Alpine Cols coaches have ridden the Etape du Tour multiple times and know the challenge extremely well. We can help you prepare in two complementary ways:

Often referred to as the toughest one-day sportive in the world, the Tour du Mont Blanc is a loop through three countries (France, Switzerland and Italy) around the highest mountain in Europe. The route covers 338km with 8,300m of climbing. These are huge numbers and the event is not to be taken lightly.
The Tour du Mont Blanc is one of the very few events during which many participants seriously wonder if they will be able to finish. Depending on weather conditions, up to 50% of the riders who cross the start line will not reach the finishing line. The event is above all an endurance challenge, and although all participants are timed, there is no official classification and all finishers receive a well-deserved “Gold” certificate.
The start is at 5am and the finish line closes at 23:59. Depending on your level, it will thus take you between ~12 and 19 hours to become an official finisher of the Tour du Mont Blanc. The challenge is at least as much mental as physical, if not more so. You will push yourself to your limits, and then have to dig deeper still, experiencing moments of euphoria followed by despair, revealing depths of character you may not have known you possess. Most participants think of quitting many times and yet manage to find the cussed determination they need to keep going.
An event such as this should be prepared over several years. If you are relatively new to cycling, we recommend you accumulate experience riding shorter events before tackling the Tour du Mont Blanc. Even if you are an experienced cyclist, we suggest riding an absolute minimum of 5,000km with at least 50,000m+ of climbing in the year before. The great majority of participants ride between twice and four times these amounts.
So how best to prepare for the TMB?
To answer this let’s take a look at the demands of the event. From start to finish, the route is a constant succession of climbs and descents with barely a single metre of flat road. The majority of the long ascensions are at an average gradient varying around 6-7%, but the col de Champex is harder, offering 10.5km at 8.2% with some long pitches at 10%. The longest climb, the col du Grand Saint Bernard from Orcières, is 24.8km and 1,580m of vertical, with the last 6.5km at close to 9%.
The weather is a major imponderable, and can turn an extremely tough event into a terrible ordeal if you are unprepared or lack the right clothes. Extremes of heat can be as challenging for some as heavy rain, sleet or even snow and the resulting risk of hypothermia for others. Even if it doesn’t rain, you may experience temperatures varying from ~0°C to ~30°C throughout the day.
Looking at the detail, these are the most important demands the Tour du Mont Blanc makes of you:
It is certainly possible to reach the finish line of the Tour du Mont Blanc without being “excellent” on all these criteria. It will, however, take longer and feel harder… Each criterion is important and your particular combination will determine your overall performance, or indeed whether or not you are able to finish.
Before working on your personal training plan, take the time to analyse your current abilities against this list to identify your strengths and limiters.
Plan not only to develop your strengths, but also work on your limiters, at least to the point where they no longer handicap you. As an example, if descending is a limiter for you, you might easily lose 5-10 minutes on each descent, adding up to as much as an hour and a half by the end. This is a shame, because descending faster is a skill you can learn which has almost no extra energy cost!
On the Cormet de Roselend
The best training plan for you is one that has been designed with your unique strengths, limiters, objectives, context and constraints in mind, and is constantly adapted for you when things change (as they inevitably do).
A very strong rider who expects to finish in less than 14 hours needs a different plan to someone who will struggle to finish in 19 hours.
A generic plan intended for all will be sub-optimum at best and potentially useless. This is why we are not providing a generic plan. The “plan” we propose below is in fact a set of guidelines and a framework for you to adopt and adapt as appropriate. Our goal is to give you the means to think carefully about the process and take responsibility for your own preparation.
HOWEVER, this is not a book and we cannot possible explain here all the nuances and individual variations inherent in the training process. We therefore strongly encourage you to use this document as an aide-memoire to what might be important, but then either to do your own research into how to apply it, or to find a coach to help you.
The key principles behind a strong training plan for the Tour du Mont Blanc are:
Note that the Tour du Mont Blanc is an exceptional event in terms of distance, climbing and thus the time taken to finish. The training guidelines we give here are quite different from those we give for the Marmotte, for example. For the Tour du Mont Blanc, the focus is almost exclusively on building endurance and related skills.
Our training plan framework begins on November 1st. This is the traditional start to a new cycling season, and gives you a little over eight months remaining to finalise your preparations for the event, which, as we have already noted, should be worked up to over several years.
A key assumption is that you will continue to ride regularly on the roads throughout the period. If this is not possible, you will have to compensate by doing long rides on the turbo and ideally by joining a training camp in the early part of the year in a warm-weather location such as southern Spain or Portugal, Mallorca or Tenerife.
To finalise your preparations, plan a training camp in the mountains in May or June and ride as much as possible in hot weather to acclimatise. Alpine Cols coaching camps are all designed to help you prepare for sportives and GranFondos up to and including the Tour du Mont Blanc.
Our suggested framework includes three phases: Preparation, Pre-Competition and Competition. Each phase is then broken down into 4-week cycles including 3 load weeks and 1 recovery week, with a target training load for each week. If you are over 50, consider adopting a 3-week cycle of 2 load weeks and 1 recovery week.
It’s important to understand that such a structure is essentially arbitrary and takes no account of the total stress you will be under (life stress + training stress) on any particular day. Current best practice is to monitor readiness to train, using a combination of daily HRV (Heart Rate Variability) measurements with perceptions of fatigue and muscle soreness, and to adjust the plan accordingly. If you feel very tired, have sore muscles and your HRV is below the normal range, it would be better either to take a very easy day or not to train at all until you have recovered. Research has shown that training when you are stressed (low HRV) provides little or no benefit and may even be harmful. Read here for more on how to use HRV to guide your training.
Remember that hard training breaks you down: you only get stronger during recovery!
In terms of intensity distribution, we recommend that for all but the very strongest riders you make your entire training for the Tour du Mont Blanc Polarised (90% low intensity, 10% high intensity).
The key objectives in this period are to accustom your body to training 10-15 hours per week and to build a strong aerobic base. Given the exclusively aerobic nature of the Tour du Mont Blanc, there is a much lower emphasis on HIT than in most training plans.
The training intensity distribution during this phase should be Polarised, meaning 90% of your training should be at low intensity and only 10% at high intensity. The percentage split is calculated on the basis of training session hours, not actual time at high intensity. A typical HIT session will last one hour (and should be counted as such) even though the actual time at high intensity may be no more than 10-20 minutes. If you add 5-10 sprints in a 4h low intensity ride, count this as 3h LIT and 1h HIT.
In practice this means that only one ride per week should include a significant amount of high intensity work.
You should completely avoid training at medium intensity (tempo or sweet-spot), because in this context it would create too much fatigue for too little benefit.
Riding slowly may sound incredibly boring and it certainly takes some adaptation, not least in your mindset. Read here for tips on how to help the time pass on long slow rides.
If you are unable to ride outside you will have to do long sessions on your turbo trainer. Read here for suggestions on how to make these more tolerable.
A good overall macro-nutrient split in terms of total kCal consumed has been shown to be 48% from carbohydrate, 24% from protein and 28% from fat[3]. Obviously each food item should be as high quality and as natural as possible. Avoid processed foods.
Finally, remember to adjust your food intake to your energy expenditure: eat more during high load weeks and cut back during recovery weeks. Keep an eye on the scales to be sure that any weight loss is slow and progressive: the priority at this stage is to fuel your training! Read here for more on nutrition while training for the TMB.
The purpose of these HIT sessions targeting the upper end of your power distribution curve is twofold: (1) increase your power at longer durations, and (2) increase your pain tolerance.
You should do no more than one per week, approximately ~10% of your training, and none during the recovery weeks.
You may not be used to off-the-bike training. Nevertheless, it can have a significant impact on your performance. To cycle faster, you need to push harder on the pedals, which means you need not only stronger leg muscles but also greater core strength to stabilise and channel the extra force. The best way to strengthen your muscles is off the bike, using appropriate exercises and good technique. Furthermore, adaptation depends on occasional changes in the training stimulation and the off-the-bike exercises are important for avoiding injury.
If you are new to this, err on the side of caution to limit the risk of injury. Good exercises to begin with include squats, lunges, planks, bridges and roll-downs. All of these require correct technique to be beneficial.
Learning correct technique is vital so choose a practitioner who knows cycling and only takes small groups (or better still runs one-on-one sessions).
The key objectives during this phase are to increase the training load to up to 20 hours per week or more and to reinforce your aerobic base by increasing the length of your long rides, while continuing to reinforce your fat-burning capacity. Unless you are a particularly strong rider, we don’t recommend HIT during this period, since HIT will create too much fatigue for too little benefit.
In spite of the low intensity, these long rides are exhausting so you cannot attempt too many, and there is no need to do more than ~60% of the event time and distance in any one training ride. Better to spread it over the weekend and work up to, for example, one 10h ride on Saturday and one 6h ride on Sunday (or vice-versa), followed by taking Monday, Wednesday and Friday off and doing no more than a short recovery spin on Tuesday and Thursday.
Either do these long rides alone or with an understanding training mate; best to avoid the weekend club run which will be too fast for what you need at this time.
It is equally important to ensure that you are fuelling your training adequately as well as not over-eating during recovery weeks. Keep a close eye on the kCal expended per ride (as reported by apps such as Strava) to guide how much you should eat.
Read here for more on nutrition for the TMB.
The key objective in this period is to eliminate fatigue without losing fitness, so that you arrive on the start line the fittest you have ever been, but also super-fresh and thus able to go the distance. The longer the event, the longer the taper: if you would normally taper 7 days prior to a typical event, taper 14 days for the Tour du Mont Blanc.
Progressively reduce your training volume by at least 50%. For example, if on the last weekend in June you do your final long rides, totalling 15h over two days, you might do two 1h recovery rides on Tuesday and Thursday, followed by riding 10h in two rides over the first weekend in July, a further two recovery rides during the week and no more than 6-7h total (in two rides) on the final weekend.
Ideally, you should arrive in Les Saisies 2-3 days before the start. Do a couple of short rides to spin the legs but nothing that will add fatigue.
The need for sleep, good quality nutrition and minimum stress are even more acute during the taper. The better you can plan to sleep well, eat well and avoid stress, the better off you will be…

[1] Ideally, you should determine LT1 via a lactate test. Failing this, you can estimate it by paying very careful attention to your breathing while starting at a very low intensity and increasing slowly. Your LT1 will be the point where you first feel the need to start breathing more deeply. For the majority of people, LT1 will be in the range 60-65% of FTP or 60-65% of HRmax

]]>I have written this article to illustrate the rapid detraining that takes place when you are forced to stop training for a lengthy period, and the long road back.
My accident took place on July 2nd 2022. I broke my collarbone (in three pieces) and badly broke four ribs as well, with numerous cuts and contusions. My helmet was broken but saved me from a head injury or concussion.
The first reaction to a broken collarbone is to do nothing and hope it mends itself. Similarly, there’s nothing one can do about broken ribs except grin and bear it. I took a heavy course of pain killers and moved as little as possible throughout this initial period.
I had an X-Ray to monitor progress on day 8. Unfortunately, this showed I needed an operation, which took place on Day 12.
My first physiotherapy session was on Day 16. These have been absolutely crucial to my recovery. In this first one the focus was on releasing tight muscles in my back, shoulder and neck that were hampering movement and causing pain, while learning some very minimal movements with the arm to start the re-education process.
Throughout this three week period I was constrained to move as little as possible, and was of course unable to do anything resembling exercise. I was therefore rapidly detraining. Research has shown significant changes after 21 days of detraining, including a rapid reduction in plasma volume which leads to a decrease in the heart muscle, reduced stroke volume and thus reduced transport of blood around the body. In addition, changes in mitochondria function begin to affect muscle endurance.
The only measures I was able to take myself were a few RHR and HRV readings (Resting Heart Rate and Heart Rate Variability), taken on days 13-18. These showed a sharp increase in RHR and a sharp decrease in HRV from my normal range pre-accident, confirming that my body was working hard to repair the damage.
After more than 3 weeks of complete detraining Day 26 was the first day I felt ready to begin some limited but regular exercise again. I started by walking barely a kilometre in just 20 minutes, and then progressively extended this to 2km, then 3km, then almost 4km in 50 minutes. It wasn’t the legs that were holding me back of course, but both general fatigue and residual pain in the shoulder and ribs.
Weekly physiotherapy sessions were important to continue releasing the many different muscles and fascia which play a role in moving the arm and shoulder. Most of these were still very tight, in a normal defensive reaction to the injury.
Every 2 or 3 days I did a series of leg strength exercises, increasing the number of repetitions and sets very progressively. By day 50 I was up to a one-hour walk every day and a short (30 min or less) leg & core strength workout every 3 days.
The big step forward on Day 61 was to sit on a bike and turn the pedals again for the first time since the accident. The main concern was my ability to take weight on my shoulders. I therefore kept the first turbo session to just 35 minutes, all in Z1 (below 65% HRmax), sitting up every few minutes to take the pressure off my shoulders.
I did a total of 8 sessions in the next 10 days, with the longest being 48 minutes.
The effects of two months of detraining were clearly visible in my HR vs. power data. Whereas before the accident I would do a 1h recovery session at around 140W and 90-100bpm, I was now finding my HR to be 15bpm higher for a power output which was lower by 15-20W. At equivalent power, my HR was 20bpm higher.
At the same time my cardiac drift (or aerobic decoupling) was in the range 5-8%, again much higher than what it was pre-accident, when I was able to ride for more than two hours at 160-180W with essentially zero drift.
For the next month I progressively increased time (but not intensity) on the turbo, time spent walking and time spent doing leg and core strength exercises. On the turbo I went first to one hour, then 1h20 and even 1h45 on Day 94. On Day 98 I tried some intensity for the first time, with 7’30” in Zone 4, which took me to 90% of HRmax.
My total training in the last two weeks leading up to 99 days post-accident was 11h per week, including roughly 6h on the turbo, 4h walking and 2h of leg and core strength workouts. My HR response was improving, but was still 15bpm above where it used to be at recovery pace. My RHR, on the other hand, had now dropped to only 2-3bpm above the normal range pre-accident, and there was a corresponding improvement in HRV.
I continued with regular physio sessions, now mostly focused on mobilising and strengthening the shoulder.
Day 100 to Day 115Oh happy day! Day 100 was coincidentally the day of my first proper ride since the accident. It was a lovely day and I was able to enjoy a 2h30 ride outside. This was half an hour longer than intended and was quite enough: I was feeling tired in the arms and shoulders by the end.
I did two more short rides out that week, as well as 5h of walking and 1h of leg and core strength work, for a total training time of 11h.
In week 16 my total training time reached 16 hours, made up of a bit less than 10h cycling outside, 1h on the turbo, 2h of leg and core strength workouts and 3h30 walking. My RHR and HRV continued their improvement and are now close to my pre-accident normal levels. Importantly, my HR response to a 1h steady ride on the turbo also improved, as I managed 129W at 101bpm and a cardiac drift of only 0.6%.
For context, in the three months prior to the accident (with the exception of a 2-week taper) I was training for an average of 17h per week, nearly all on the bike, with a 30-45 min leg and core strength workout and an occasional 30 min swim. At the time I didn’t record my walks, but they were at most 2h per week..
At the end of this period I felt ready to tackle a 3h ride, which I did on Day 118.
During the next three months I intend to stabilise my average training load at around 15-16 hours per week (including cycling, swimming, walking and strength workouts). I will be continuing to monitor my readiness to train using HRV, perceived fatigue and the SFT test (read here for more on this), and will adjust my training plan based on my body’s readiness to benefit from the load.
My goal is to recover and even improve my pre-accident aerobic condition. This will mean a high volume of low-intensity work combined with a small amount of high-intensity to recover some anaerobic fitness through the winter period, and then adding more event-specific sweet-spot and high-intensity work in the spring and early summer.
If all goes well, by late spring of 2023 I should be back to normal!

The post Recovery from a serious accident, Part 1 first appeared on Alpine-Cols.
]]>The post HRV: what is it, why should you care? first appeared on Alpine-Cols.
]]>High intensity training only has a positive effect if your body is in a condition to benefit from it. It is therefore of considerable value to find ways of measuring your readiness to take on a high intensity session.
This is why you should care about Heart Rate Variability (HRV): it can help you significantly increase the effectiveness of your training. It does this by guiding you to do your hard training sessions on days when your body is primed to accept hard training, and to recover on the days when your body needs recovery and will not benefit from hard training.
This is a big step forward on either following a fixed plan, which by its nature cannot take into account your body’s constantly varying ability to benefit from an intense session, or deciding purely on feel, which is too subjective to be effective.
“If you’re not listening to your body (and coach!) & adjusting your training accordingly, it’s certainly possible to put in 700 hours of training & not improve one bit!” – Alan Couzens (Exercise Physiologist, triathlon coach)
The supporting evidence for the use of HRV includes not only studies that show HRV-guided athletes improving more than those following a standard plan, but also that the phenomenon of “non-responders” (which is often seen in research studies) can disappear. Non-responders are a sub-set of the athletes under study, who show no statistically-significant change as a result of the training intervention. In one recent study, a group of Finnish researchers led by Olli-Pekka Nuuttila have shown that this phenomenon can even disappear completely when the training load is adjusted based on three measures: HRV, perceived fatigue & muscle soreness, and an index based on heart rate/running speed (HR/RS).
The equivalent index for cyclists to HR/RS would be heart rate at a set power output, or the Submaximal Fatigue Test (SFT). More on this in the appendix below.
Three measures taken together provide insights into the individual’s day-to-day state of recovery and thus ability to benefit from high intensity training:
In the remainder of this blog post, we will look mostly at HRV before concluding with our recommendations for how to use these three measures for the most effective training.
The use of Heart Rate Variability (HRV) has grown significantly over the past decade, and it is being used by more and more amateurs as well as professional athletes across a wide range of sports. As always, we at Alpine Cols learn as much as possible and test ideas before writing about them on the blog, so the following is the result of almost three years of experience. Based on this, I believe that any serious athlete – by which I mean anyone who trains hard for challenging objectives and cares about their performance – should consider using HRV to inform their training.
Why? Well, we have any number of precise measures to monitor our training load (e.g. hours, kilometres, power, TSS, CTL; …) but far fewer to monitor how we are responding to that load. In fact, most of the measures used to monitor response to training load are largely subjective, such as perceptions of soreness, fatigue, stress, sleep quality, overall feeling, etc. So how do I know whether I should train today at high intensity, at low intensity or not at all? How fatigued is too fatigued? What if I’m feeling a bit ‘meh’? Or if I’m stressed by something?
Until the advent of HRV, there was no objective way of knowing whether it would be better to stick with the plan, to change the workout or to cut the workout altogether. Most plans were (and still are) built on the theory of periodisation, often with three load weeks followed by one recovery week. The basic idea of load followed by recovery is of course valid, but the rigid framework often leads to disappointing outcomes and may explain why some people get labelled “non-responders”.
Without appropriate measures, it’s not possible to predict accurately either the ability to take on load productively or the need for recovery, and indeed these may vary for the same person from one week to the next. On occasion, I may be able to load for three weeks straight, on others I need to stop loading after just ten days. Equally, sometimes I might need eight days to recover, while other times three days are sufficient.
Enter the notion of HRV. Where Heart Rate (HR) is simply a measure of the number of beats per minute, Heart Rate Variability is a measure of the regularity of your heart rate, or, the extent to which the time between each beat varies. In practice the time between beats varies slightly, and the variation provides useful data.
To understand what’s going on we need to know that both HR and HRV are modulated by the autonomic nervous system in response to stress. The autonomic nervous system has two branches, the sympathetic branch and the parasympathetic branch. The sympathetic branch is activated by stress and assists in the famous ‘fight or flight’ response. If you need to be able to fight or run as hard as possible, your heart must beat powerfully. This increases your HR while reducing the variability between beats: your HRV is therefore low. On the other hand, the parasympathetic branch is responsible for the body’s resting functions, and is dominant under conditions of rest and low stress. In this case your HRV is high.
Measuring HRV thus gives you an insight into the state of your autonomic nervous system and therefore the level of physiological stress you are currently under. This is the combination of acute stressors, such as hard training, a long flight, illness, or an evening of heavy drinking; and chronic stressors, such as chronic disease, long term challenges, financial worries or relationship difficulties at work or at home. HRV can’t tell the difference between these various stressors; it effectively sums them up. This doesn’t matter because your ability to benefit from hard training is affected by the total stress, not the training stress alone.
In the words of Andrew Flatt (Associate Professor in Sports Medicine, specialist in HRV research):
“When tasked with recovering from training & coping with excess stress, recovery loses every time. Energy is diverted from muscle growth/repair to sustaining the alarm response by shifting from anabolic to catabolic processes, & from parasympathetic to sympathetic activation.”
If you are already under excess stress, adding training stress will only make things worse!
More and more wearables provide a measure of HRV taken automatically during the night. At first sight seductive, this may not be the best approach since during sleep you are still recovering from the stress of the previous day. Much better to take the measurement under your own control in the exact same conditions every morning, immediately after waking up. At this point you can best evaluate the extent of your overnight recovery.
Use an app on your mobile phone. For a number of reasons we recommend HRV4Training as the best app currently available. (Beyond using the app ourselves, we have no links with HRV4Training). You can either use the camera and flash together as an optical sensor, or, pair the phone with a top quality chest strap such as the Polar H10. The two are equally valid. Most people find using the camera slightly quicker and easier.
The measurement takes one minute. Both RHR (Resting Heart Rate) and HRV are collected at the same time. You are then asked to reply to several questions (including sleep quality, muscle soreness, travel and alcohol consumption) which can help in interpreting the measure and making correlations. You can link the app to Strava so that it will pull in your training data from the previous day, and to Training Peaks so it will upload the results.
The measurement is useless in isolation and there is no value in comparing your data to anyone else’s. It is only useful when compared to your own data, established over the longest time period possible (at the very least one week). HRV is not something you measure occasionally: either you get in the habit of doing it every day, or it is pointless. The value is only meaningful in context and in comparison to your own normal values.
When you begin measuring your HRV on a systematic basis you will soon see that it varies quite a bit from day to day. Some of this variation is completely normal. The question is, therefore, when should we be concerned, or what level of change is “not normal”?
One of the principle reasons we recommend the HRV4Training app is that it calculates and displays your normal values as a range. These are based on the previous 60 days of data, which has been shown to provide the best balance between acute and chronic responses. It is these normal values which make the data actionable, by identifying whether your responses are showing meaningful changes or just small variations that you should ignore.
The way to interpret the data changes depending on whether you are interested in short-term acute changes or in long-term trends.
First, look at your daily reading. So long as this is within the normal range, all is good. Stick to the training plan, and do exactly what it says (whether high intensity, medium intensity, low intensity, short or long, or even a rest day: do whatever the plan says).
On the other hand, if the daily measurement falls outside your normal range, and your plan calls for either a high intensity ride or for a very long ride, you should seriously consider changing the plan. You don’t necessarily have to take a rest day but it’s advisable to stick to a very easy pace and limit the duration.
Once a week or so, zoom out to look at the long-term trends. Changes in the normal range over time indicate how your body is adapting to chronic physiological stress. If the trend is to a higher value for HRV, this is a sign that you are coping well with the current level of stress. On the other hand, if the trend is negative, this is a warning sign that the stress is having a detrimental effect. As noted above, HRV alone can’t discern between the different types of stress (training, illness, travel, etc.) so it is important to interpret the data in your personal context. Look for correlations between your HRV and the known sources of stress you are under.
1. High training load resulting in short-term acute stress.
In October 2022 I rode the Cent Cols Challenge. This consisted of riding 1,850km and climbing 38,000m in just ten days (with a rest day in the middle). The average day was thus 185km and 3,800m. Needless to say this is rather more than I normally ride in one day, let alone ten days in a row. Here are my RHR and HRV responses (the ten-day period is indicated by the double arrow):
In this case, the response was equally marked in RHR and HRV, which is to be expected when the stress is entirely related to a big increase in training load. Note that the short-term effect is to increase RHR and decrease HRV, whereas the long-term effect should be the opposite. Both RHR and HRV were clearly outside the normal zone from the first day to the sixth, at which point they started to stabilise, signifying my body was becoming better accustomed to the load. Both recovered to be within the normal range the day after completing the Challenge, suggesting that my autonomous nervous system was well on the way back to its normal condition.
2. Heavy cold resulting in short-term acute stress.
Just before Christmas I caught a heavy cold, with a visible response on both RHR and HRV:
Note that the day-to-day response is more sensitive in HRV than in RHR, with the exception of 24/12. I didn’t do any training at all during this period. On 28/12 I did a 2h turbo session with a few high-intensity intervals at the end (6x 40/20, 6×30/30 and 6×20/40). The effect was immediately visible in a below-normal HRV the following morning, which recovered the day after. This indicates that I wasn’t yet in good condition to benefit from the HIT. Under normal conditions, HRV should not be affected by a single day of HIT. If it is, it implies that either the session was too hard for your current level, or HRV is being affected by some other stressor.
3. Long-term adaptation to training load.
The data here is for the range March 1st to May 15th, a period when I was training very consistently, including cycling, strength training and swimming, averaging 16 hours per week:
RHR has a slight decreasing trend, while HRV has a clear increase throughout the period. This indicates that, viewed over the long term, my body was tolerating the training load very well.
4. Effects of an accident.
The accident occurred on July 2nd. I broke my collarbone quite badly as well as 4 ribs. Since I take my morning readings using a chest strap, I was in no state to do so for the first few days. The effects are still extremely obvious 2 weeks later, with my RHR some 20 beats above the trend pre-accident, and my HRV showing an equally impressive drop. I took 5 measures and then left another two week gap without taking any. When I started again, on Aug 4, both RHR and HRV were close to the (new) normal range, but some way away from the pre-accident normal range:
Looking now at the data in the period from two to three months post-accident, it shows a slow positive trend in both RHR (reducing) and HRV (increasing). RHR is only a couple of beats off the pre-accident normal. HRV is still depressed. This confirms that I am still in the recovery process and my sympathetic nervous system is still quite active. I am therefore avoiding high-intensity training for the time being and concentrating on rebuilding my aerobic capacity.
If you are serious about improving the effectiveness of your training, you should consider using HRV.
Getting started is easy: install an app on your phone (we recommend HRV4Training, but there are alternatives) and begin measuring every morning. A one minute measurement is sufficient. You can’t do anything with the data until you have established a normal range, which requires 7 days of data.
From this point on, use your morning reading as an indicator of the daily state of your autonomic nervous system:
HRV alone is not sufficient, however. You should also take into account your perceptions of fatigue and muscle soreness: if both are high, even if HRV is normal, skip the high-intensity session.
Once a week, do a Submaximal Fatigue Test (SFT) as an added input to confirm whether or not your body is accepting the current training load.
As a final word, this brief article can only serve as an introduction to the subject. Most of what I have learned comes from experts such as Marco Altini, Andrew Flatt and Alan Couzens. I encourage you to read their articles and follow them on Twitter to learn more.
This test was developed by Jeroen Swart, Performance Coordinator at UAE Team Emirates. It is very simple and can be done weekly:
The effort should feel like 17/20 on the standard RPE scale, which goes from 6 to 20.
If all is well, RPE should be down and HR either similar to the previous week, or if well rested it may be a little higher, showing a positive response to the stimulus. If, on the other hand, your RPE is up and your HR is down (for the same power), it’s a clear indication that you are fatigued. (The HR response to the SFT is thus the opposite to what you would expect to see when measuring your RHR first thing in the morning. RHR should be similar or slightly lower if well rested and recovered, but higher if fatigued).
Over the long term (two to three months) you would expect to see a slow decline in HR at current FTP, due to increased fitness, as well as an increased estimate for Time To Exhaustion.

The post HRV: what is it, why should you care? first appeared on Alpine-Cols.
]]>The post Lactate profiling at Alpine Cols coaching camps first appeared on Alpine-Cols.
]]>Starting in 2022, we are offering lactate profiling at all Alpine Cols coaching camps. The benefit is to determine your training zones accurately, and especially to identify your base training aerobic threshold.
The simplest reply to this question is that if we train at the “wrong” intensity, we won’t get the adaptations we are training for. In other words, our training will be at best sub-optimum and at worst either a partial or a complete waste of time!
If I take my own personal case, I discovered through lactate profiling that I have been doing my low-intensity endurance rides too hard for years, thus creating a lot of extra fatigue for no benefit and preventing me from becoming as strong as I could have been.
How do we know how hard the workout should be, and then how do we know how hard it is in practice? These questions are a lot more complex than they might appear, but I’m going to keep things as simple as possible.
“How hard” is a function of both time and intensity. Our concern here is with the intensity, and how to prescribe the right level in terms that we can reliably carry out on the bike. This is usually done by reference to training “zones”, which begs the question: how are these zones determined?
Many amateur riders and their coaches determine their zones using one of the auto-calculation methods such as those in Training Peaks, e.g. Dr Andrew Coggan’s 6-Zone model (originally published in Training and Racing with a Power Meter). Plenty of other models exist. Some may use 5 zones, others 7 (or more) but in most cases the zones are based on percentages of a single reference value such as Functional Threshold Power, Maximum Aerobic Power, Functional Threshold Heart Rate or Maximum Heart Rate.
There are three problems with all of these auto-calculations.
The first is the accuracy of the reference value, (e.g. FTP) all of which are subject to significant estimation and measurement errors. The second problem is that the percentages used to calculate the zone boundaries (e.g. Coggan defines the top of Zone 2 as 74% of FTP) are based on population averages and take no account of individual differences. There are in fact wide variations between people, with the result that the zone boundaries can be out by as much as 30-40W and 15-20bpm. I’ll come to the third problem below.
So if we can’t rely on individual FTP or heart rate measurements to determine our zones, what can we do?
Our Zones should be determined by measuring our own specific physiological markers.
There are two key physiological markers that are widely used in endurance sport: blood lactate and the gas exchange ratio. If you do a lab test both will be measured. They provide different and complementary ways to identify the same physiological threshold, which together with Critical Power can then be used to set our own individualised Zone models. This is the way training zones are set for professional athletes, and now the wide availability of portable lactate test units has made the method available to the amateur peloton too.
This brings us to our third problem with the common training zone models: there is no scientific validity for anything more than 3 zones, because there are only two physiological markers. The changes that take place below LT1, between LT1 and LT2 and above LT2 are continuous and the decision to split any of these 3 zones into two or more is arbitrary and purely for convenience.
To put it another way, cross either LT1 or LT2 and our bodies start to respond differently (see below for more). Cross any of the intermediate zone boundaries in a 5, 6 or 7 zone model and nothing of note changes, it’s just slightly more of the same. There is a specific sprint zone at the very top end but this is of little or no relevance to Granfondo riders.
The chart shows a typical lactate profile for an amateur cyclist. The profile was obtained via a step test in which the cyclist pedalled at a series of pre-determined power levels, staying at each level for 3 minutes (long enough for heart rate and blood lactate to stabilise). The lactate was measured in the final minute of each step, via a drop of blood extracted from a pricked finger.
Both heart rate and lactate are plotted against power, and the lactate threshold (LT1, the point at which lactate begins to increase from base levels) can then be read from the lactate curve. This particular test was carried out with 30W steps every 3 minutes, leading to some uncertainty as to where to estimate LT1: it could be anywhere between 150W and 170W. To increase the accuracy the steps could be reduced to 15 or 20W.
It is theoretically possible to read LT2 (the point at which lactate production exceeds its rate of clearance) from the same curve but this is subject to interpretation error as there’s no obvious breakpoint. For some people, this is roughly the same level as FTP. Many scientists and coaches agree that Critical Power is a better way to measure it.
To determine Critical Power we need to do at least two and ideally three max efforts with durations between 2 and 20 minutes. The relationship between power and duration in this timeframe follows a simple mathematical formula so it is easy either to calculate Critical Power yourself or use an online calculator. In my case, I use Golden Cheetah to do it automatically.
Now we have our two physiological markers, we have our three zones.
If you want to use five zones you can split Zones 1 and 2 into two zones each, making LT1 the upper bound to Zone 2 and LT2 the upper bound to Zone 4. You can then further split the high intensity Zone 3 (from the three zone model) into three more zones, 5, 6 and 7. Whether there’s any point in doing this will depend on the event you are training for and on your (or your coach’s) preferences.
