What this race demands
The 100 km de Millau requires sustaining forward motion across an ultra-distance road running format over 1100 meters of elevation gain.
Ultra Distance Endurance
Covering 100 kilometers on foot places extreme demands on musculoskeletal durability, soft tissue resilience, and pacing discipline.
Climbing Management
Accumulating 1100 meters of elevation over the course requires efficient climbing mechanics and careful energy management to prevent premature fatigue.
Given the extended duration well beyond 2.5 hours, athletes must commit to a structured carbohydrate intake of 60 to 90 grams per hour to sustain energy levels.
