This event takes place just south of Albertville in the Savoie region of France. It has become very popular since it first started in 2013 and now attracts top-level trail runners. Runners have the choice of three courses: the Intégrale (149km), Traversée Nord (87km) and Parcours des Crêtes (62km). The Intégrale consists of 90 percent single-track and takes runners from 271m to a high point of 2892m at Belledonne Cross. All three courses provide beautiful views of the surrounding lakes and mountains.
