Gère ta boucle - Chailles 2026

Gère Ta Boucle is a loop-format trail race in Chailles, Loir-et-Cher, France, organized by Génération Trail Blois. The race has a simple cutoff: finish each loop in under one hour or you cannot start the next. Runners choose between 3-hour, 6-hour, and 12-hour challenges, completing 3, 6, or 12 loops respectively if they stay within the time limit. Each loop is approximately 7.5 km with 180 m of elevation gain. The race focuses on repeating the same effort while managing pace, rest, and nutrition. A refreshment point is located at the end of each loop, with available time there dependent on your loop completion speed. This event is in its second edition after a successful first running, and entries are limited.
