Lapland´s flagship: rugged gorges, wooden bridges, and nonstop national park trail through the legendary Bear’s Trail.
Finland’s largest trail running event starts at the Arctic Circle — at Napapiiri, where the 83 km race fires at 22:00 in late May. At 66°N, darkness barely applies: you’ll cover the legendary Karhunkierros (Bear’s Trail) through Oulanka National Park in near-perpetual twilight, past river gorges, suspension bridges, and boreal pine forest from Hautajärvi all the way to the ski village of Ruka. Elevation is gentle by ultra standards — 1,890 m of gain across 83 km (22.77 m/km official) — ranking this among the least vertical courses in the database. The course follows Finland’s most iconic long-distance hiking trail, well-marked and largely runnable, with wave starts and cutoffs at Oulanka (5h, 27.6 km) and Konttainen (15h, 77.1 km) before the 18-hour finish limit. Running since 2013, NUTS Karhunkierros drew 544 starters in the 83 km for 2026, with 436 finishers. ITRA certified. Entry is €194.90 (~2.35 €/km). Kuusamo Airport (KAO) is 28 minutes from Ruka, but international connections are limited — most runners connect via Helsinki. A sauna and hot soup await at the finish.
