Held during the week of July 26–August 2, 2025, the Kia Fjällmaraton Week is Scandinavia’s premier mountain running festival in the Årefjällen region, set amidst the rugged terrain of Jämtland, Sweden. Over eight days, runners can take on a range of trail events from short-distance Vertical km and 5–27 km races to the classic 45 km Kia Fjällmaraton with 1,800 m climb, and the demanding 100 km ultra featuring 3,300 m elevation gain . The 45 km route traverses the Jämtland Triangle—Ottfjället, Hållfjället, and Välliste—with support stations and a wooden finisher’s medal “proving” completion within time limits. The ultra and shorter-race fields draw both elite and recreational runners, with the 50 km and above distances now part of the Spartan Trail World Championship series. Organizers provide sustainable, participant-focused support—including electric Kia transfer shuttles, feed stations serving Umara drinks and local foods, and race village activities—emphasizing trail culture and minimal ecological impact.
