Raid du Bugey is a non-timed road cycling event held in Lagnieu, Ain department, eastern France, typically at the end of April. Participants can select from three hilly routes: the full Raid du Bugey, approximately 130 km with about 2,400 m of elevation gain; Portes du Bugey, around 80 km with roughly 1,680 m; and a shorter 50 km discovery ride with less climbing. The event is organized by Déchaine Ton Coeur, a local association that raises funds for medical research through sports and cultural activities.
The routes traverse the Bugey hills, featuring climbs such as Col des Fossés, Col de Fay, and the higher Col de Portes. From Col de Portes, a view of the Rhône is visible, marking a clear point on the longest route. This event is designed for road cyclists seeking distance and elevation without competitive timing, with its charitable mission being key: proceeds and contributions directly support chosen research programs, including pediatric cancer research by a Lyon-based team.
