Raid Lozère Sport Nature starts from Mende in the Lozère department of southern France, with Parc de Wunsiedel used as a launch point for the long-format race. It is a team multisport raid rather than a standard running race: competitors switch between mountain biking, packraft, trekking, and orienteering, with electronic chips used for timing and for checking each control or activity change.
The hardest version sends teams of four over about 330 km with roughly 9,000 m of climbing across 48 hours, and everyone on a team must stay together. The route can begin with a short orienteering section in Mende, move onto the Lot river by packraft, and use mountain-bike maps where each section has a separate start and finish. The village orienteering is unusual because there may be no physical markers on the ground: racers use an aerial photo map, match real places to a set of photos, and ignore decoy images that do not match any control. The event also runs shorter youth and discovery raids, and some competitors travel from outside France, including Belgium.
