Blefjells Beste Troll Route: Norway's Most Remote 57km Mountain Loop
Norway's remote cabin-country ultra for runners who want the mountains without the crowds. Blefjells Beste covers 57km and around 1830–2000m D+ on a loop from private cabin Bestebu on the Blefjell massif in Numedal, Buskerud — no formal aid stations, mandatory gear, and occasional reindeer for company. More than a third of the course follows Nordmannsslepa, the historic T-marked trail spanning the length of Store-Ble, with off-trail moorland and exposed plateau terrain filling the rest.
The finale drops through narrow, increasingly steep singletrack that runners describe as flying. Tiny and deliberately so: around 150 starters per year, organized since 2015 by Langt og Lenge volunteers. Entry starts at 975 NOK (1.5–2€/km), not sold out. ITRA awards 2 points and Mountain Level 3; UTMB Index classifies it as a 50K race. Oslo Airport is 2 hours by car; a race-day shuttle runs from Lampeland. Note: the 2026 Troll route was shortened to 53km — check the official site for updated course data.

Is Blefjells Beste 57km suitable for first-time ultra runners?
Is Blefjells Beste 57km suitable for first-time ultra runners?▼
The 14-hour time limit and relatively gentle average gradient (ranking 304 of ~390 in the DTR database for uphill steepness) make Blefjells Beste physically accessible to experienced trail runners attempting their first ultra — but zero formal aid stations and mandatory gear requirements mean the race is self-sufficient by design. You carry all food and safety equipment for 57km on remote exposed moorland. If you're comfortable navigating Norwegian mountain terrain unsupported, this is a manageable but genuinely wild first ultra.

Fully Self-Sufficient: Blefjells Beste 57km'sTroll Route Has Zero Aid Stations
Are there aid stations on Blefjells Beste's Troll route?
▼
No — ITRA officially records zero aid stations for the Troll route. Every runner carries all their own food, water, and safety equipment for the full 57km. Mandatory gear applies regardless of weather forecast, and the race strictly enforces this: the course crosses remote exposed Blefjell plateau with no infrastructure. This is a defining design choice by organizer Langt og Lenge, not a gap in the event logistics — Blefjells Beste is explicitly a self-sufficient mountain experience.
How Do You Get to Blefjells Beste 57km's Remote Start at Bestebu Cabin?
How Do You Get to Blefjells Beste 57km's Remote Start at Bestebu Cabin?▼
Yes, but it requires planning. Oslo Airport (OSL) is approximately 2 hours from Lampeland and Flesberg by public transport (check Entur app for connections). The start/finish at Bestebu cabin sits at the end of an 8km dirt mountain road with very limited parking capacity. The race organizes a shuttle bus from Lampeland and Flesberg on race morning — this must be booked and paid for in advance during registration. Overnight accommodation in Lampeland or Flesberg is strongly recommended for runners arriving by public transport.
Record Year and Small Field: The Blefjells Beste 57km Finisher Profile
How many runners finish Blefjells Beste 57km?
▼
UTMB Index records confirm 74 finishers in 2024 from an approximately 150-participant field. Internal low-confidence data suggests around 91 finishers in 2025 — a likely record year consistent with a Kondis headline calling it "rekordstor" (record-large). The race deliberately limits its field to around 150 runners across all distances, making Blefjells Beste among the most intimate UTMB Index 50K races in Scandinavia.
