Hasetsune Cup 71.5km 2026
Also known as: HASETSUNE CUP · Japan Mountain Endurance Race
Okutama's mountain endurance race, held since 1993. Starting from Itsukaichi at midday, runners follow ridges over Mt. Shoto, Mitosan and Odake through the night, then descend the Konpira ridge back to the start. Water points are few, so self-sufficiency is part of its tradition.
The course tops out at 1,511 m (low point 171 m). There are 2 big climbs: 817 m around 0–18 km; 682 m around 24–37 km. About 40% of the distance is gentle (under 5% grade). In 2025, 73% of starters finished. The median finish was about 18 h, through one night.
