MANNO MOUNTAIN MADNESS 80 km 2026
Also known as: MMM 100mile · MMM
Two laps of the roughly 40km loop in the Asan Mountains on the Kagawa–Tokushima border: the first in the dead of night, the second from dawn, so the same course shows two very different faces. Between laps runners can restock and change at their own car or the gym at the start.
5,600 m of climbing over 80 km (70 m per km). In 2025, 54% of starters finished — a tough one. The median finish was about 16 h, through one night.
