Les Défis de la Boucle - Etape 1 2026

Les Défis de la Boucle - Etape 1 is a 10 km night trail race in Fontain, a village in the Doubs department of Bourgogne-Franche-Comté in eastern France. It is scheduled for mid-November and is the first stage of the Défis de la Boucle series. The event keeps its format simple: a short off-road race after dark, with the town itself part of the atmosphere. Organizers describe it as a “party in town,” and the program includes separate routes for children and juniors, making it suitable for families as well as adult runners.
