From 25 July to 1 August 2026, the Kia Fjällmaraton Week unfolds across the mountains of Åre and Undersåker, Sweden, with a packed program of trail races. Distances include 8 km, 12 km, 27 km, 45 km (Kia 45K), 100 km, plus the iconic Vertical K (5 km with 1,000 m elevation). The highlight, the Kia 45K, takes place on 1 August 2026, challenging runners with ~1,400 m of ascent, including the crossing of the legendary Ottfjället ridge. Courses traverse alpine meadows, birch forests, technical singletrack, and sweeping ridgelines, supported by aid stations and festival logistics. With a week-long atmosphere of community, music, and mountain culture, Kia Fjällmaraton Week is both a celebration of Scandinavian outdoor life and a test of trail running endurance.
