N3PUC 100mile (self-challenge) 2026
Also known as: Nishikan 3 Peaks Ultra Challenge
A self-run 100-mile challenge on the Nishikan Sanzan, the three peaks of Kakuda, Yahiko and Kugami in Niigata. Runners repeat a loop that links the ridge-traverse trail with road sections, entirely self-supported with no aid stations or course marking.
The course tops out at 622 m (low point 3 m). About 50% of the distance is gentle (under 5% grade). In 2026, 58% of starters finished — a tough one. The median finish was about 37 h, through one night.
