Rock n'Trail is a trail running event held in the local quarries of Muneville-le-Bingard, in Normandy's Manche department. The event's identity stems from its quarry setting, offering runners a rough, mineral course instead of a soft forest trail. The program features a short loop of approximately 7 to 7.6 km with 160 to 200 m of elevation gain, a 20 km trail race, and 24-hour formats for solo, duo, and team participants.
