CLAM TRAIL 2026

Clam'Trail is an urban trail race held in Clamart, southwest of Paris. Its course alternates between neighborhood streets and woodland paths. While recent editions took place in autumn, the next race date is unconfirmed; runners should verify with the organizer before registering. The event features two distances: a 20 km route with 315 meters of elevation gain and a 10 km route with 128 meters of elevation gain. The route crosses the streets of the Galvents Corby neighborhood and the trails of the Bois de Clamart, offering more variety than a flat road race while remaining close to the city. Organized by CSM Clamart, it welcomes participants running solo, with family, or with friends. Aid stations and changing rooms are available on-site. Non-runners can participate by volunteering at the start village.
