Les Trails de Rousset Serre-Ponçon is a trail running series held in Rousset, a village in the Hautes-Alpes of southeastern France, with races in early June. Participants can select from 10 km, 18 km, 23 km, and 36 km distances, catering to both short trail runs and demanding mountain efforts. The routes wind through the village, nearby mountains, and the lake area close to Serre-Ponçon.
The 36 km Tour de la Viste is the longest event, featuring 1,850 metres of elevation gain, and the 23 km Trail du Lac requires 1,100 metres of ascent. Over 100 runners participated in each of these distances during the last edition. The 18 km Trophée des Celliers is contested as a three-person relay, with each team member running 6 km. The 10 km Trail du Belvédère offers the shortest distance on the schedule.
