Duo Trail Cavalaire-sur-Mer takes place in late October in Cavalaire-sur-Mer, on the Var coast of Provence-Alpes-Côte d'Azur, France. The format is key: it is run as a two-person race, meaning you enter and cover the course with a partner, not as a solo runner. The event provides short and longer trail options, approximately 11 km and 25 km, plus a discovery-distance course for those seeking a more accessible introduction to the format.
The Cavalaire race serves as the Côte d'Azur stage of the Challenge Duo Trail, a four-event series organized by ExpéNATURE. The series also includes a spring race at Pourrières / Sainte-Baume, a summer race at Isola 2000 / Mercantour, and a winter Snow Duo Trail, also at Isola 2000 / Mercantour. The Cavalaire event utilizes the coast and local trails, where shared effort is as important as speed. It is designed for runners, trail fans, hikers, and pairs looking for a race completed side by side.
