[A CONFIRMER] Trail Malassis - 13 km 2026

The Trail Malassis Tour is a short nature trail race held in Mantes-la-Jolie, located in the Yvelines department of Île-de-France. The primary 13 km course involves an ascent of approximately 200 metres. This event is typically scheduled for mid-November; however, participants should confirm the precise date with the organizer before registering. The race takes place within the French Vexin region, featuring trails that wind through forests, across hills, and alongside sections of the Seine River. AS Mantaise is the organizing body, and participants also have the option of a shorter 6 km course. The 13 km distance is the preferred choice for many, appealing to runners seeking a concise trail race with sufficient elevation gain to provide a genuine off-road challenge.
