La Trace des Wolfs is a trail running race held in Gambais, Yvelines, west of Paris. It is scheduled for February and offers two off-road courses: a 15 km route with 275 m of elevation gain, or a 30 km route with 475 m of elevation gain.
The shorter course is suitable for those seeking a concise trail race featuring significant hills. The 30 km option provides a longer run without entering ultra-marathon territory. Specifics like the entry fee should be confirmed with the organizer, and Frédéric Maury is the listed contact for race details.
