第27回NACトレイルランinニセコ 2026

NAC Trail Run in Niseko is a mountain trail race around Niseko Annupuri in Kutchan, Hokkaido, with the listed race day falling in September. Annupuri is a ski resort in winter, but in summer it turns into a mountain route with about 1,000 meters of elevation difference. Runners can choose roughly 5 km, 10 km, or 30 km, so the event ranges from a child-friendly beginner option to a hard mountain run. The 30 km race includes real climbing rather than road-style running on gentle paths. The 10 km stays inside the ski resort area, while the 5 km is meant for beginners and children who want a shorter trail experience. The series is listed as the 27th NAC Trail Run in Niseko, which points to a local event with a long enough history to have built a regular place on the Hokkaido trail calendar.
