21 km de l'Yvette - Bures-sur-Yvette 2027

The 21 km de l'Yvette begins at Stade Chabrat in Bures-sur-Yvette, Essonne, at 10:00 AM in late March. This 21.1 km run focuses on trails and local paths, differing from a road-only city race. The course follows paths through the Chevreuse valley, connecting Gif-sur-Yvette, Orsay, and Chevreuse. Organized by the Mairie de Bures-sur-Yvette, this race is in its early stages, having just completed its second edition following a successful debut. Descriptions highlight the course as unique and diverse, with an affordable entry fee aligning with its character as a community event rather than a large commercial undertaking.
