Try some real mountain biking! Expect struggle, sweat and achy legs. Cykelvasan 45 is the mountain bike race for those who want a real challenge but aren’t yet ready for the 90 km. The first 15 km of the race are technically advanced and probably Cykelvasan’s most demanding stretch. The race is 45 km, starting in Oxberg and running on 37 km of forest road, 6 km of gravel and 2 km of asphalt before reaching the Mora finish line.
