In the world of trail running and endurance sports, sports nutrition often comes up as a central element of success. While physical training is crucial for preparing for a race, nutrition strategy is just as important, or even more so in long and demanding events.

But can a single nutrition plan be applied to all races, regardless of their duration, difficulty, or weather conditions? Many runners think that what worked in one race can be systematically applied to others. However, every event is unique and presents specific challenges, making it necessary to precisely adapt your diet before, during, and after the competition.

In this article, we will explore why a personalized approach is essential. We will draw on concrete examples, such as the strategies used by athletes in iconic events, and explain how to adjust your nutrition plan for each race to maximize your chances of success.

1. The importance of personalization according to the type of race

Every race is unique, and trying to apply a universal nutrition strategy, regardless of the distance or conditions, risks harming your performance. Several factors make personalization essential:

The duration of the race

The length of a race directly influences your energy needs. In a 10 km race, the effort is intense but relatively short, requiring little on-course fueling (you can keep a gel in your pocket just in case), or none at all for some runners. Conversely, an event such as the 90 km of Mont-Blanc requires meticulous energy management over several hours, or even an entire day.
A nutrition plan suited to long distances, such as the one presented in the nutritional strategy guide for the 90 km of Mont-Blanchighlights the importance of regular carbohydrate intake and a consistent supply of electrolytes to prevent fatigue.

Weather conditions

The climate plays a decisive role in your nutritional needs. Racing in hot weather causes increased mineral salt loss through sweating, increasing your electrolyte needs. Conversely, in cold weather, your body burns more calories to maintain its temperature, requiring a higher energy intake. As will be the case during the SaintéLyon, for example.
A nutrition plan that neglects these differences risks causing dehydration or a calorie deficit, compromising your performance.

Your physical condition and training

Every runner has a unique metabolism and specific needs that vary according to their physical preparation. A well-trained person often has a better ability to use fat stores as an energy source, which can influence the amount of carbohydrates to consume during a race. Likewise, a runner who is not accustomed to long distances will need to pay particular attention to their intake to avoid running out of energy

The race profile

Elevation gain, terrain type, and variations in intensity also influence your needs. A mountain race with long climbs requires different energy management from a flat course where the effort is more consistent.

Why adapt your nutrition plan?

Sticking to a standard plan regardless of the type of race can lead to deficiencies or, conversely, unnecessary overconsumption. A personalized approach not only addresses the specific demands of the race but also maximizes your chances of finishing in great shape.

Preparing for a race isn’t just about running; it also means adjusting your nutrition to the conditions, just as you would for your training. The key to success lies in this ongoing adaptation to each new challenge. For a nutrition plan tailored to your needs, we recommend consulting a dietitian specializing in endurance sports. Indeed, a professional who practices the same activity as you is more likely to understand your needs

2. Learn from experts for better effort management

When it comes to nutrition and effort management, athletes’ experiences are a valuable source of inspiration. They demonstrate the importance of adapting your strategy to each race, whether in terms of distance, course profile, or conditions.

Take the example of Théo Detienne, who recently shared his strategies for the Grand Trail des Templiers, a demanding race because of its elevation gain and intensity. In this detailed article on Nutri-Bay, he explains how he adjusted his energy intake and hydration to meet the specific demands of this event.

What we can learn from his approach:

1. Anticipating energy needs Théo planned regular carbohydrate intake to avoid dips in performance, while taking the race duration into account. This strategy is particularly relevant for long events, where glycogen stores are quickly depleted.
2. Adapting to actual exertion : During the race, he adjusted his plan according to how he felt. A particularly difficult climb or a change in weather can alter your energy or hydration needs, requiring you to review the quantity or frequency of your intake.
3. Managing unexpected situations : Even with perfect planning, it is essential to prepare additional options (energy gel, recovery drink, solid foods) to adapt to unforeseen conditions or a bout of fatigue.

Learning for all runners

This type of example shows that your nutrition strategy must be flexible enough to meet the specific demands of a race. What works for a short, intense event will not be suitable for an ultra-trail race where endurance is paramount. Drawing inspiration from the experience of athletes such as Théo Detienne can help you refine your own habits, but these adjustments must be tested during your training or in real-life conditions, such as during training camps.

In short, learning from the best means not only understanding their approaches, but also knowing how to personalize them to meet your specific needs based on your level, goals, and the nature of the upcoming event.

3. The key role of training camps and simulation

To adjust and validate an effective nutrition plan, nothing compares to real-life practice. Training camps or race simulations are ideal opportunities to test and refine your nutrition strategy. This process is essential to avoid unpleasant surprises on race day and optimize your performance.

Testing your strategy in a realistic setting

A training camp organized in conditions close to those of your target race allows you to experiment with your nutrition plan in several ways:

●       Digestive tolerance : Certain energy drinks, gels, or foods can cause digestive discomfort, especially during prolonged efforts. Testing these products in real-life conditions helps identify which ones suit you best.

●       Intake timing : Determining the ideal frequency for consuming carbohydrates, electrolytes, or protein is crucial. This rhythm varies according to your effort intensity and level of fatigue.

●       Hydration : Depending on the temperature and humidity, your hydration needs change. Training camps allow you to adjust the quantity and composition of your drinks to avoid dehydration or electrolyte imbalances.

Identifying unexpected situations

Training camps also expose you to unexpected situations, whether capricious weather, an unexpected feeling of fatigue, or an equipment problem. These experiences teach you to react quickly and adapt your nutrition according to the circumstances.

For example, if you realize that your gel intake rate causes saturation or nausea, you can explore other options such as more substantial energy bars or natural foods (dried fruit, salted potatoes).

Improve consistency between training, nutrition, and goals

Training camps are not limited to nutrition: they also help align your food choices with your training strategy. This ensures better integration between physical exertion and recovery, and helps you identify the key moments when your nutrition plan needs to evolve.

Concrete example: preparing for an ultra-trail

If you are targeting a race such as the 90 km Mont-Blanc or a similar ultra, training camps are particularly important. You can test your ability to consume carbohydrates regularly over several hours, manage intense exertion phases (technical climbs, fast descents), and adapt your diet according to the available aid stations. This process prepares you mentally and physically for the event’s specific demands.

Training camps for all levels

Whether you are a beginner or experienced, a training camp tailored to your goals will benefit you. For beginners, it is an opportunity to learn the basics of sports nutrition in real-world conditions. For seasoned runners, it allows them to fine-tune the details and experiment with new approaches.

4. Toward a comprehensive yet adaptable strategy

Although it may be tempting to apply one universal method to all your races, the reality of trail running and endurance sports requires an approach that is both rigorous and flexible. An effective nutrition strategy rests on solid foundations, but it must be adapted to each context to help you perform at your best.

The essential foundations of sports nutrition

Certain rules apply to every race, regardless of the format:

1. Hydrate regularly : Dehydration significantly affects performance, even over short distances. On average, it is recommended to drink between 500 and 750 ml per hour, but this figure may vary depending on the weather conditions and intensity of the effort.
2. Maintain a consistent energy intake : To avoid hitting the dreaded "wall," it is essential to consume carbohydrates regularly—30 to 90 g per hour, depending on the duration and intensity of the race.
3. Prioritize easy-to-digest foods : Your stomach is put under considerable strain during a race, especially at high intensity. Foods that are too rich or poorly tolerated can cause digestive problems and ruin your efforts.

Why is adaptability essential?

Each race has its own specific characteristics that make adjustments essential:

●       The race format : A short race (10 km or a half marathon) may rely on energy stores accumulated before the start, whereas a multi-hour ultramarathon requires continuous fueling to avoid exhaustion.

●       Available aid stations : In some races, aid stations offer specific foods or drinks. You must adapt your strategy to incorporate these options or bring your own supplies if the available choices do not meet your needs.

●       Your personal goals : Are you aiming for a specific finish time or simply to finish? The intensity and duration of your effort directly influence your nutrition plan.

How do you find the right balance?

1. Plan ahead : Take the time to study your race profile (distance, elevation gain, climate) and plan an appropriate nutrition strategy.
2. Test in real-world conditions : As discussed in the section on training camps, test your strategy before the race to validate your choices and make adjustments if necessary.
3. Be ready to improvise : Even with the best planning, unforeseen events can arise. Learn to listen to your body and adjust your intake according to how you feel.

A concrete example of successful adaptation

During the Mont-Blanc 90 km, runners must manage a long race with significant elevation changes, sections exposed to changing weather conditions, and aid stations spaced far apart. A well-designed nutrition plan, such as the one presented in the dedicated strategy guide, offers concrete solutions to meet the demands of your races. But even within this framework, each runner will need to adjust the plan according to their physical condition, how they feel, and the unexpected circumstances encountered along the course.

Toward a personalized and evolving strategy

The goal is not to reinvent the wheel for every race, but to start with a solid foundation and adjust it according to the event’s specific requirements. By combining thorough preparation, testing in real-world conditions, and flexibility, you can build an effective and sustainable nutrition strategy

In summary

The key to successful sports nutrition lies in balancing fundamental principles with adaptability to each situation. By understanding the specific needs of each race and drawing on experiences such as those of Théo Detienne or the recommendations for the Mont-Blanc 90 km, you will be better equipped to take on any challenge, whatever it may be.
