Seine-Marathon 76 2026

The Seine Marathon 76 begins in Rouen, France, in the Seine-Maritime department, gathering over 15,000 runners each September. This Normandy running event includes a marathon, half marathon, 10K, and 5K, accommodating everyone from seasoned marathoners to casual runners, younger participants, and older athletes. The event emphasizes a festive, community atmosphere, integrating solidarity, environmental respect, sporting values, and Rouen’s heritage into its core identity. The marathon route is largely flat, tracing the Seine before entering Rouen’s historic heart. Participants will pass the Botanical Garden, Rouen Cathedral, the Gros-Horloge, and the Museum of Fine Arts, with local residents cheering from the streets. Though only seven editions old, the race attracts a significant crowd and possesses a distinct local character, blending a road race with a city-wide event. French runners Aurélien Declosmesnil and Camille Chaigneau have both claimed victory, demonstrating that the elite competition can be strong while the broader event remains accessible and communal.
