MTB Marathon & Gravel Challenge 2026

The MTB Marathon & Gravel Challenge begins and ends in Hillerød, Denmark, on an October Sunday. It offers mountain bike marathon routes of 103 km, 57 km, and 32 km, alongside a gravel race of approximately 63 km. The MTB marathon is an XC bike race, and the organizer states it is Denmark's largest and oldest event of its kind. October weather in the Hillerød area is typically cool, with crisp, cloudy conditions, occasional sunshine, and temperatures frequently ranging from 6°C to 14°C. The longer MTB routes utilize multiple start groups, from Elite to Motion, separating faster competitors from those focused on completion. The gravel route follows a distinct course for over half its length, with about half of it on gravel paths separate from the MTB riders. The event fosters a significant local cycling atmosphere: Peter Reibert Hansen of Allerød OK is involved in the organization, and the event is described as a "big bike party" in Hillerød.
