The Trail des Fontaines is a trail-running series featuring six timed races, from a 7 km option to a 105 km ultra. The routes emphasize trail running over road running, with abundant singletrack and technical sections requiring stable footing and fitness.
The Ultra Trail des Fontaines is the longest event at 104.62 km with approximately 4,000 m of elevation gain and descent. The Marathon du Malbec spans 44.81 km with 1,743 m of ascent, and the Belcours Trail covers 32.8 km with 1,175 m of climbing. The Rose Marie Trail is 14.43 km with 452 m of climbing. For 20 years, the organizers have supported runners, presenting the event as a comprehensive trail weekend rather than a single race.
