Trail de Barbizon is a small early-autumn trail running event in Barbizon, Seine-et-Marne, near Paris in the Île-de-France region. The main race is a discovery-level trail of about 12 to 12.5 km, with children’s races over 900 m and 1.8 km, making the day suitable for families and adults trying a short trail race.
The longer route is a single forest loop, with elevation figures varying between sources, from nearly flat to 250 m of climbing. The setting is the main draw: Barbizon is situated by the forest, and the event targets runners seeking a nature race over a road run through town. Approximately 350 participants are expected, positioning it as a local community race rather than a large trail festival.
