About this race
Mud defines the Kluisberg Trail, a February race held in Kluisbergen, Belgium. The wet hills frequently transform the course into a slick challenge. It provides multiple distances, such as 25 km and 35 km, with the 25 km route featuring 735 meters of elevation gain. This event marks its ninth edition and its 25 km distance has been recognized on the UTMB Index calendar.
The course crosses rolling forest paths, cobblestone segments, ascents near Kluisbergen, and offers open vistas of the Flemish countryside. The 35 km choice is intended for trail runners seeking a more demanding day with diverse terrain and significant elevation. The 25 km race can attract a substantial field for a local event, having seen over 600 finishers, and appeals to participants who appreciate muddy conditions, steep inclines, and a course where adverse weather intensifies the challenge.
