The Trail de la Plaine - 11 km is a trail race held at Stade du Sibano in Noisy-le-Roi, Yvelines, west of Paris. The 11 km race begins in the morning, includes approximately 90 meters of elevation gain, and is part of a larger local event featuring a 22 km trail race, a 3 km race, Nordic walking, and a 1 km children’s race.
The race is described as “100% nature,” emphasizing a short off-road run over a demanding mountain course. Participants receive a meal with their entry. The event also includes a village area with a tombola, activities, and games. One euro from each registration supports the association Un Pas Vers La Vie. Entry numbers are limited, making early registration advisable for this community-focused race.
