Trail Malassis Tour 2026

The Trail Malassis Tour is an annual trail race held at La Butte Verte in Mantes-la-Jolie, located in the French Vexin west of Paris. It typically takes place in November and features two short off-road courses: 6 km and 13 km. These distances are suitable for novice runners, local participants, and those seeking a brief trail race instead of an extended mountain-style event. The routes follow local paths around La Butte Verte, combining forest trails, paved lanes, inclines, and sections alongside the Seine River. A portion of the course extends into the Bois des Beurons within the Rosny forest. The 6 km route is designed for a rapid run over varied terrain, while the 13 km route offers more extensive woodland, ascents, and riverside running. Now in its sixth edition, the race's primary draw is its straightforward, local trail format situated near the town.
