Hvittingfoss Trail Challenge 2026

The Hvittingfoss Trail Challenge is a demanding trail race held in Hvittingfoss, Norway, starting and finishing at Hvittingfoss skole. It takes place on a Saturday in September and features two distances: 25 km and 54 km. The shorter course includes 1200 vertical meters of ascent, and the longer course ascends 2500 vertical meters, indicating it is a challenging event. The organizers refer to it as Buskerud's most difficult trail run, a description supported by the course profiles, which show significant elevation gain over compact distances. Participants can select either the 25 km route or the longer 54 km option, with registration managed via EQ Timing.
