Planning Your Ultra-Trail Race: The Invisible Skill of Great Trail Runners

Performance in ultra-trail isn't just about training. It's also built on paper, long before the starting gun. After dozens of ultras and a few records, one observation consistently stands out: many athletes train seriously, but very few truly plan their race.

In ultra-endurance, the differences rarely come down to physical condition alone. They come down to effort management, nutrition, hydration, aid station strategy, and the ability to anticipate difficulties.

It is precisely for this reason that having a detailed plan is essential: a tool that transforms a course into a complete roadmap with split times, segmented sections, nutritional strategy, hydration needs, weather forecasts, and aid station points.

Three Fundamental Principles of Ultra-Trail Planning

1. A Race is Built Before the Start

In an ultra, most mistakes stem from a lack of anticipation, not a lack of physical fitness. You might know your training plan by heart but ignore the essentials: what time you'll reach aid stations, how much water to carry between two points, how many carbohydrates to ingest, what temperatures to face, where the critical sections of the course are located.

Without these answers prepared in advance, fatigue will make decisions for you. Planning means making important decisions while you are still clear-headed and rested.

2. Nutrition is Prepared Like a Training Session

In a 14-hour ultra, needs can reach 60 grams of carbohydrates and 500 milliliters of water per hour. In total: 840 grams of carbohydrates and nearly 7 liters of water over the entire race.

These quantities cannot be improvised at the 60-kilometer mark. You need to know precisely what you're starting with, what you'll take at aid stations, when to eat, and when to refill your flasks. Waiting for feelings of hunger or thirst means the deficit has already set in.

The golden rule: plan your nutrition before the physiological need arises. In ultra-endurance, prevention is always better than correction.

3. Split Times Reassure and Guide

Many athletes avoid looking at their projected split times, fearing added pressure. Often, the opposite happens: a good plan reduces uncertainty.

Well-calibrated split times help you to:

  • Pace your effort from the start
  • Start at the right pace
  • Anticipate difficult moments
  • Maintain your rhythm on less demanding sections

Each race can be broken down into segments with distances, elevation gains, estimated times, projected schedules, and expected weather conditions. When fatigue sets in, this breakdown serves as a mental map: a clear direction to follow, without having to recalculate everything in the fog of exhaustion.

A good plan gives you a stable benchmark at the precise moment your mental resolve wavers.

Scientific Insight: Implementation Intentions

Psychologist Peter Gollwitzer (1999) studied why some intentions turn into concrete actions while others remain unfulfilled. His discovery: transforming a vague goal into a structured "if... then..." plan ("if a certain situation arises, then I will act in this way") significantly increases the chances of sticking to a decision, even under fatigue or stress.

These implementation intentions work because they link the decision to an identifiable signal in advance. The brain then executes an already prepared response instead of having to arbitrate mid-race, under cognitive strain.

Application in ultra-trail: A good race plan multiplies the "if... then..." statements: so many decisions made upstream, before fatigue sets in and impairs your judgment.

The Philosophy of a Good Planning Tool

The goal of an effective planning system is to bring together everything that matters before a start:

  • The detailed course
  • Key segments
  • Projected split times
  • Weather forecasts
  • Aid station locations
  • Hydration plan
  • Carbohydrate strategy

To answer one fundamental question: does my plan hold up?

In ultra-endurance, performance is primarily built in preparation. The best trail runners are not just those who train the most; they are those who arrive at the start with a clear, tested, and adjusted plan.

Key Takeaways

  • An ultra-trail race should be prepared like a structured project
  • Key decisions must be made before the start, not during the effort
  • Nutrition and hydration are planned precisely, down to the hour and gram
  • Split times reduce uncertainty and guide your pace
  • A good plan helps maintain your clarity when mental fatigue sets in

In trail running, the mountains are already unpredictable enough. It's best to control what can be controlled. Planning isn't an extra constraint: it's your best ally to transform solid preparation into real performance on race day.
