Trail du Chalam is a village trail-running event in La Pesse, Haut-Jura, with the start and finish located in the village. It takes place in September and features two main off-road distances: 15 km and 10 km. Separate races are organized for adolescents, and a playful course is available for younger schoolchildren from CP to CM2.
The race is central to La Pesse’s patronal festival, not a standalone running event. The village organizes two days of activities around it, including sport, crafts, food, and drinks. The Union Sportive et Culturelle de La Pesse coordinates the event, with several local associations assisting in running the wider festival. This brings runners, families, volunteers, and village groups together in a shared program.
