Course & Elevation
The Lyon marathon is part of Run in Lyon by Harmonie Mutuelle, an event organised by A.S.O. on the first Sunday of October, alongside a half marathon, a 10 km and a 5 km Run Solidaire. All races start in the Vieux Lyon, on the Saône quays opposite the former Palais de Justice, and finish at Place Bellecour. The 2026 marathon used a new route without the Croix-Rousse tunnel: it follows the Saône for around 8 km, crosses the river at the Paul-Bocuse bridge at Collonges-au-Mont-d'Or, returns through the Presqu'île to the Terreaux at about 16 km, then runs through the Parc de la Tête d'Or and the Cité Internationale before dropping to the Rhône banks and Gerland. It finishes via the Raymond-Barre bridge, the Confluences museum and quai Rambaud. The time limit is 5 hours 30 minutes. A marathon in Lyon was first run in 1983, created by the Jeune Chambre Économique de Lyon, and the Run in Lyon event began in 2010. The women's course record is 2:43:34, set by Jeanne Garreau in 2025. In 2026 about 36,000 runners took part across all races, and the next edition is set for Sunday 3 October 2027.
