Randonnée du Téléthon is a December charity event in La Roche-sur-Yon, located in the Vendée department of western France. Organized by Cyclo Touristes Yonnais, participants gather at the Office des Sports Yonnais before starting in the morning. The entry fee is modest, with a reduced rate for club members, and registration takes place on-site.
The event offers multiple participation options: a road cycling route of approximately 74-75 km, shorter cyclo routes around 57 km, gravel routes of 52-55 km, and walking routes from 6 to 10 km. Its defining tradition is its fundraising purpose; all proceeds are donated to AFM-Téléthon. The day emphasizes participation for a cause rather than competitive results, bringing together local cyclists, gravel riders, and walkers.
