Kitamusashi GIANT'S GATE 2026
The first edition, themed on giant legends of the northern Musashi hills. From Nagatoro Genki Plaza, runners do a southern loop via Mt. Dodaira and Sadamine Pass, then a northern loop via Mt. Jinmi and Mt. Fudo. The course is unmarked, GPX navigation is required, and aid is mostly water and salt.
The course tops out at 873 m (low point 103 m). There are 4 big climbs: 543 m around 0–8 km; 729 m around 20–32 km; 436 m around 57–63 km; 427 m around 69–74 km. About 30% of the distance is gentle (under 5% grade). In 2026, 74% of starters finished. The median finish was about 18 h, through one night.
