Dutch Masters of MTB 101 km E-Bike Marathon

Dutch Masters of MTB is a 200 km mountain bike ultra-marathon starting in Haarle, with riders beginning shortly before sunrise. It is considered the toughest MTB challenge in the Netherlands. The format is more akin to a full-day survival test than a standard marathon, requiring attention to pacing, nutrition, hydration, bike handling, and mental fortitude. The target finish time is approximately 13 hours, meaning most riders spend the majority of the day managing their energy rather than maintaining a consistent rhythm. The route crosses Salland and the Sallandse Heuvelrug, with over 70% of the course off-road. Riders navigate singletrack, forest roads, gravel paths, and extended climbs, demanding both speed and technical skill. Several significant aid stations are available, including a main one near the halfway point, yet the event emphasizes rider self-sufficiency. In a nation where many routes are flat and quick, this event distinguishes itself through its length, rugged terrain, and demanding latter half, establishing it as a key event for Dutch marathon and ultra mountain bikers.
