Ultra Raid Des 3 Vallées 2026

The Ultra Raid des 3 Vallées is a three-day mountain bike raid held in Miavoye, Belgium. It combines stage racing with XC marathon riding, an uncommon format for Belgian mountain biking. The main event, the Ultra 6000, spans 273 km across three days and includes 6,846 meters of elevation gain. The course crosses three Belgian valleys via off-road trails, with the longest day reaching 140 km on Saturday. Over 400 cyclists participate in the challenge, attracting a broad field rather than a niche group. Mathias Cloostermans won the primary race by leading all three days, followed by Benjamin Rosart and Ludovic Recolet.
