Raid Nature Vercors 2027

Raid Nature Vercors is a team adventure race in Isère, on the edge of the Vercors, with recent editions based in Saint-Romans and Chatte. It is run around late May, and it is not a simple running race: teams move through several disciplines, including trail running, mountain biking, bike-and-run, orienteering, and a surprise event. The format gives racers a shorter and a longer option, with recent courses listed around 30 to 43.6 km for the discovery route and 60 to 70.6 km for the harder challenge. Teams can include 2, 3, 4, or 5 people, so the day is built around navigation, pacing, bike handling, and teamwork rather than just individual speed. The Discovery results are tracked separately, which underlines that the event makes room for newcomers as well as teams looking for the longer raid.
