Boucles du château - Dormans 2027

Boucles du Château - Dormans is a 12.5 km night trail race in Dormans, run inside the park of the Château de Dormans. The main race is timed, and the format is simple: three loops after dark, with 240 meters of climbing across the route. Racing Club de Dormans organizes the event, which is on its sixth edition. The course is built for a broad field, with beginners and more experienced runners both in mind, and separate youth races give younger runners their own start instead of mixing them into the main trail race.
