Défi de Derborence

Défi de Derborence begins in Aven, Swiss Valais, offering three races and one food-focused E-bike ride. The race choices include mountain biking, trail running, and junior duo orienteering, catering to off-road riders, runners, and younger teams rather than a single discipline. All courses start in Aven. The gourmet E-bike route travels through the vineyards of Vétroz and Conthey, while other routes proceed on paths in the Mayens-de-Conthey. This is the event's sixth edition, featuring on-site catering and music in the event area post-race.
