Trail Runner Nutrition: Why Protein Quality Matters in Your Preparation

In trail running, preparation is built on several pillars: training, recovery, sleep, and nutrition.

Carbohydrates naturally hold a central place in endurance sports. However, when you're stacking long runs, elevation sessions, strength training, and high-volume weeks, proteins also become a major part of the equation.

And beyond the quantity consumed lies another question: what quality of protein are you really putting on your plate?

It's precisely around this reflection that Trail Running Lab welcomes Féroce among its Trail Running Lab partners.

A French brand specializing in meats and fish selected according to several criteria: nutritional density, origin, traceability, farming or fishing methods, and laboratory analyses. An approach that directly aligns with our vision at TRL: understanding what we do, measuring what can be measured, and building performance on solid foundations.

Why Proteins Are So Important for Trail Runners

Running in the mountains places significant demands on the body.

Each training week combines repeated muscle contractions, impacts, positive elevation, descents, energy fatigue, and physiological adaptations. Nutrition then supports the mechanisms of recovery and adaptation to training.

Recent research in endurance athletes indicates protein requirements are higher than those of the general population. A study published in 2023, following a 20 km effort, estimated around 1.6 g of protein per kilogram per day as the intake associated with maximizing whole-body protein synthesis in the participants studied. A review published in 2025 suggests around 1.8 g/kg/day as a relevant benchmark for many endurance athletes, with adaptations based on training context and energy intake.

For a 70 kg trail runner, this represents, for example, about 110 to 125 g of daily protein at these intake levels.

The goal remains simple: distribute your intake throughout the day with complete meals adapted to your training load.

Proteins and Trail Running: Looking Beyond the Grams

Two meals showing a similar quantity of protein can provide very different nutritional profiles.

Animal products are notably sources of complete proteins, as well as vitamin B12, heme iron, zinc, selenium, and various B vitamins. The Féroce dossier also highlights the integration of liver, heart, and kidneys into certain products to increase their micronutrient density.

For the trail runner, this concept of nutritional density deserves a real place in their dietary strategy.

Training creates needs. The plate provides the necessary materials for the body's functioning. Regular meals and food diversity then transform this logic into sustainable habits.

This is where the Féroce philosophy becomes interesting.

Féroce: An Approach Based on Traceability and Measurement

Féroce develops a range of meats and fish around five pillars: nutritional density, documented controls, traceable origin, production systems, and daily practicality.

Each product is associated with an origin, a supply chain, and a batch. The brand also documents the producers and their practices.

One of the points we find particularly interesting at TRL concerns the analyses accessible to the consumer.

Depending on the product and the supply chain, Féroce analyzes various nutritional markers as well as relevant contaminants such as heavy metals, drug residues, or pesticides. The available results can be accessed via the QR code on the label.

Concretely, the process looks like this:

1. You scan the product's QR code
2. You access information about its origin and producer
3. You consult the available analyses

This is exactly the process presented in the Féroce dossier.

For a sports community accustomed to analyzing its kilometers, elevation, heart rate, load, or RPE, this logic of transparency applied to nutrition makes a lot of sense.

When Farming Systems Also Influence Nutritional Profile

The origin of a food tells only part of the story. Farming practices, animal feed, and fishing methods also influence the composition of products.

Féroce thus indicates that, for certain analyzed and compared products, omega-3 levels reach up to four times those of organic or conventional references used in their comparisons. The brand also conducts analyses, depending on the products, for fatty acids, vitamins, or minerals.

This approach allows for moving from a marketing promise to measurable and consultable information.

And at TRL, we're pretty fond of data.

What Does a Féroce Box Actually Look Like?

The operation aims for simplicity.

Féroce currently offers two formats, Box M and Box L, customizable with different meat and fish references. The frequency can be chosen from several rhythms, and each delivery arrives frozen at your home.

The idea is to create a ready supply of proteins at home that are easy to integrate into your weekly meals.

For a trail runner juggling work, training, recovery, and personal life, this organization brings one precious thing above all: simplicity.

Some examples of use:

• ground meat with rice and vegetables after a session;
• fish, potatoes, and vegetables for a recovery dinner;
• meatballs with pasta and vegetables during a high-volume week;
• meat, starches, and vegetables in a complete meal after a long run.

Féroce also offers certain recipes combining muscle meat and offal, with the goal of integrating more micronutrients into formats that are simple to cook.

And After a Big Trail Run?

After a long or intense session, nutritional recovery relies on a coherent combination of carbohydrates, proteins, hydration, and overall energy intake.

Carbohydrates notably contribute to replenishing glycogen reserves, while proteins support protein synthesis and training-related adaptations.

On Trail Running Lab, we have already dedicated a trail nutrition and hydration guide, with benchmarks on carbohydrates, sodium, hydration, and post-effort recovery.

The approach remains the same: thinking of nutrition as a continuation of training.

You plan your sessions.

You adapt their intensity.

You organize your high-volume and recovery weeks.

Your nutrition deserves the same consistency.
