Trail de Saint-Didier is a trail-running event held in Saint-Didier, located in France’s Vaucluse department. The event offers a range of distances, from shorter runs suitable for the village to a long trail race. Distances listed include approximately 8-9 km, 13-14 km, 26-27 km, and 42-44 km. The longest route involves a climb of about 1,950 metres. The 26 km race requires significant climbing ability, with approximately 1,000 metres of ascent, while the shorter races maintain a challenging profile without being flat.
The day's schedule is organized by distance, beginning with the long race. This is followed by the 26 km, the 13.4 km, and finally the shortest run. Some event details also note a 14 km option that can be completed individually or in pairs. The organizer is Les Mollets Petillants. This race is rooted in the local trail-running club community rather than large-scale urban road races, featuring diverse distances, substantial climbs, and a format that accommodates both seasoned trail runners and those preferring shorter distances.
