Marathon Bresse Dombes - Châtillon-sur-Chalaronne 2027

The Marathon Bresse Dombes begins at the hippodrome in Châtillon-sur-Chalaronne, a medieval town in France’s Ain department. The main race is available solo or as a relay for teams of two or four. The program also features a half marathon, 10 km, 5 km, children’s races, and walks from 7 km to 12 km. The marathon follows a figure-8 course with 310 meters of elevation gain, winding through the Dombes ponds, Bresse countryside, and past several castles before proceeding toward Vonnas, the hometown of chef Georges Blanc. From Vonnas, it merges with the half marathon route back to Châtillon. Pacers will be available on course, along with shuttles to the half marathon start. Aid stations will be well-stocked, costumes are encouraged, and solidarity walks will support cancer research. The finish line is in the town center, under the Porte de Villars, near the long market halls.
