Tanzawa Looooooops 33 km 2026
Also known as: Tanzawa LOOPS
One lap of a loop around Oyama in the Tanzawa mountains, starting and finishing at a base right by Hadano Station and passing Yabitsu Pass. It is a self-challenge event rather than a ranked race; for 2026 the former Oyama circuit has been partly rerouted for safety.
The course tops out at 1,244 m (low point 79 m). There are 2 big climbs: 1,154 m around 0–13 km; 435 m around 18–20 km. About 40% of the distance is gentle (under 5% grade). The median finish was about 9 h.
