Kick off your trail season with a legendary and notoriously muddy challenge on the outskirts of Paris at the **MaxiCross on January 31 & February 1, 2026**. This historic event in the Forêt de Montmorency, known for its prehistoric heritage and vast gypsum quarries, offers four distinct distances over the weekend: an 18 km and a 10 km race on Saturday, followed by a 25 km and a demanding 42 km on Sunday, plus a 10 km walk/hike. With a reputation as the early-season proving ground for the region's top athletes, the course's steep slopes and deep mud promise to test your legs and resolve like few others.
Residents of Bouffémont enjoy free entry for the 10 km events, highlighting the strong local community spirit. Registration typically opens well in advance, so keep a close eye on the official channels to secure your spot before the races fill up. Whether you're tackling the long, grueling 42 km or the fast and furious 10 km, the MaxiCross delivers a uniquely tough, authentic, and unforgettable trail running experience just minutes from the French capital.
