What this race demands
This 500 km multi-day gravel and road cycling event requires sustained effort over a 52-hour time limit across the Gulf of Morbihan and the Lanvaux moors in early April.
Ultra-distance endurance
Covering 500 km across a three-day event demands exceptional aerobic capacity, pacing discipline, and the ability to manage fatigue over consecutive days of riding.
Mixed surface durability
The combination of gravel and road terrain requires equipment reliability and constant physical engagement to absorb vibrations and handle varied traction throughout the route.
Sleep and recovery management
The 52-hour window necessitates effective time management for rest, nutrition, and mechanical maintenance to sustain performance through the designated period.
A consistent intake of 60 to 90 grams of carbohydrates per hour is required to maintain energy levels during prolonged efforts over multiple days.
