Long distance trail nutrition: field method
Long distance trail nutrition must follow the real terrain: rolling portions, technical sections, aid stations and weather require simple and anticipated decisions.
Article outline
Key takeaways
Point 1
Think in blocks of land rather than in abstract theory.
Point 2
Maintain a minimum autonomy between two refuelings.
Point 3
Adjust intake formats according to intensity and technicality.
Point 4
Always have a simple digestive fallback plan.
1) Structure the race into nutritional blocks
Identifying the areas where eating/drinking is the easiest and those where it is especially important to maintain. This mapping limits omissions.
A robust trail plan provides for opportunistic intakes without abandoning the overall time frame.
2) Balance autonomy and supplies
Relying solely on supplies increases the risk. An autonomous base stabilizes the strategy, then supplies serve as reinforcement.
The logistics margin must cover a delay or less supply than expected.
3) Protect digestive tolerance during racing
When running becomes technical, simplifying textures and returning to easy intakes helps maintain input without discomfort.
Anything new must be tested in training, not discovered on the day of the objective.
FAQ
Liquid only on trail?
Not always. A liquid/solid mix is often more robust depending on the profile.
Should we completely modify the ultra-trail plan?
The framework can remain the same with more checkpoints and margins.
How to limit slack?
By taking it regularly and anticipated, without waiting for the energy to drop.
How to manage discomfort while climbing?
Temporarily reduce concentration and gradually return to routine.
