Shinetsu Five Mountains 100mile 2026
Also known as: SFMT
A one-way journey linking the five Shinetsu peaks on the Niigata–Nagano border, from Madarao Kogen to the finish at Iizuna. It starts in the evening and runs through the night; a pacer may join from Kurohime, and family or friends can crew at the aid stations.
The course tops out at 1,747 m (low point 226 m). There are 3 big climbs: 1,022 m around 60–80 km; 927 m around 93–123 km; 602 m around 127–144 km. About 40% of the distance is gentle (under 5% grade). In 2025, 44% of starters finished — a tough one. The median finish was about 31 h, through 2 nights.
