Kraftloppet MTB is a mountain bike race held at Bergsvallen, Bergsbyn SK in Skellefteå, Sweden. Starts are scheduled for late morning, with the finish closing by mid-afternoon. Participants can select either a 56 km or a 21 km course. The event also includes shorter races for children, covering 6 km and 2.7 km.
The route crosses hilly terrain, distinguishing it from a simple flat ride. The 56 km race offers a competition class, a recreational class, and a recreational electric-bike class. This distance also serves as a qualifier for CykelVasan. Elite riders and amateur cyclists utilize the same event base, where food and light refreshments are available for purchase by both participants and spectators.
