Tyin Filefjell Extreme 2026

Tyin Filefjell Extreme is a high-mountain running weekend at Tyin Filefjell in early September, with the main race day on Saturday. The race menu has three distances: the 7.5 km Børren se Skyrace, the 21 km signature half marathon, and the 53 km Tyin Filefjell Ultra. All three routes run through mountain terrain, with autumn colors around the course and rough nature rather than city streets. The event is built for a wide field, from first-time mountain runners to people chasing personal goals, and the weekend program includes spectators, running culture, and good food; the ultra is the newest option for runners who want to keep their season going with something longer and steeper.
