ROUND GIRLS 100 160km 2026
Also known as: Round Girls 100
A women-only race on a roughly 20 km loop of the Fujiyama Power-line Trail and nearby forest roads, based at Fujisan Kodomo-no-Kuni park in Fuji City, Shizuoka. Generous aid, cheer squads and pacer/support options are built in to help runners finish. The 100-mile starts in the evening and runs eight laps across two nights.
The course tops out at 934 m (low point 660 m). About 60% of the distance is gentle (under 5% grade), so there is a lot of running. In 2026, 78% of starters finished. The median finish was about 33 h, through 2 nights.
