Course de la Passerelle is an April trail-running event in Pratz, a village in France’s Jura department in Bourgogne-Franche-Comté. It has been running since 1996 and uses the Haut-Jura setting for short, nature races rather than a big-city road format. The main adult options include a 12 km solo trail with about 450 m of climbing, a two-person relay over 2 x 6 km with 180 m of gain per runner, a 4-hour non-stop format on a 6 km loop, and untimed 6 km or 12 km hikes with free starts.
The course is built around forest paths and Haut-Jura countryside, with the 6 km loop giving the event a compact structure for relay teams and the endurance format. It is aimed at a mixed local field: solo trail runners, pairs who want to split the effort, walkers, families, and children all have their own place on the program. The children’s races cover ages 3 to 15, from 300 m for the youngest to 2300 m for older juniors, and they cost 2 euros on site. Those kids’ races have no rankings, and every finisher gets a gift at the line.
