The Trail du Chemin des Dames is a trail race held in Chamouille, Aisne, northern France, on the historic Chemin des Dames site. The event features three race distances: a 12 km night race, a 12 km daytime race, and a 25 km race. All races include approximately 300 meters of elevation gain.
The race routes traverse a natural landscape connected to local history, with courses designed around the heritage of the Chemin des Dames region. This event is suitable for runners seeking short to mid-distance trail running, rather than ultra-distance mountain races. The 12 km night race offers a distinct experience on the same historically significant terrain.
