TAMBA100 100mile 2026
Also known as: TAMBA 100
A selection-based 100-miler that leaves Tanba-no-Mori Koen in Tamba City, Hyogo, at dawn and links the city's mountains. It grew from the idea of joining the area's rugged hills into one route and has been featured on NHK BS's 'Great Race'.
The course tops out at 1,000 m (low point 81 m). About 30% of the distance is gentle (under 5% grade). In 2026, 45% of starters finished — a tough one. The median finish was about 54 h, through 2 nights.
