Fjällmaraton

Q: What is the Fjallmaraton 100K? A: The Fjallmaraton 100K is a point-to-point fell ultra running 100km from Fangamon to Ottsjo through the high Jamtland fells of central-west Sweden. The course gains 3,300m D+ (33.0 m/km) with an 8.81% distance-weighted average uphill gradient and -9.04% average downhill gradient (both LOWER-MID tier) -- a runnable fell ultra on sustained moorland and boggy terrain rather than technical alpine rock. The race takes place on Thursday 30 July 2026 as part of Fjallmaratonveckan, a full week of mountain running events including the classic KIA 45K Fjallmaraton (running since 2005), a half-marathon, a vertical kilometer, and children's races. It is part of the Spartan Trail World Championship Series and is ITRA-listed. Entry is tiered from 1,800 to 2,300 SEK. Not sold out.

Q: Is the Fjallmaraton 100K part of a race series? A: Yes. The Fjallmaraton 100K is part of the Spartan Trail World Championship Series, giving the race international competitive significance beyond the Scandinavian circuit. It is also ITRA-listed (results confirmed for 2024 and 2021 editions; specific ITRA points not confirmed in Stage 1 research -- check ITRA listing at Stage 5). The race is Buff-sponsored and one of several Spartan Trail circuit events. Within the Fjallmaraton Week context, the 100K shares the brand with the classic 45K associated with Emelie Forsberg (multiple wins), Ida Nilsson (4 wins), and Jonathan Albon (2021). No course records for the 100K distance are currently in the DTR database.

Q: What is the terrain like on the Fjallmaraton 100K? A: Approximately 98% single trail across sub-arctic moorland and boggy fell. The course traverses Ottfjallet, Hallfjallet, and Grofjallet at roughly 700-1,200m elevation. Distinctive features include plank walkways over wetland sections, knee-deep mud possible even in good weather, and free-running reindeer commonly visible on the first ascent at km 21. This is not technical alpine terrain -- no rock scrambling, no exposed ridges. The physical demands are sustained boggy fell running: soft ground significantly increases energy cost relative to dry mountain path at equivalent gradients. Average July conditions: variable weather, ~13 C background temperatures, rain possible at any time. The 2022 race was notably clear and sunny after a wet July buildup -- conditions vary widely year to year.

Q: How much does the Fjallmaraton 100K cost and when is it held? A: The 2026 race takes place Thursday 30 July 2026. Entry is tiered: 1,800 SEK (early, until 31 Jan 2026 -- past); 2,100 SEK (standard, until 31 May 2026 -- past); 2,300 SEK (late tier, until race day 31 Jul 2026) -- approximately EUR 195-200 at current exchange rates. The auto EUR/km figure is EUR 1.995/km at the standard tier. Registration is not sold out. The Fjallmaraton 100K is part of a full race week (Fjallmaratonveckan); accommodation in Ottsjo is limited -- base in Are and travel to start/finish, booking well in advance given race week demand.
