Overview
Kumano Old Trails runs across a 52-kilometer course starting from Kumano-Shi, Mie Pref., Japan, taking runners past local landmarks such as the Kumano Kodo, Maruyama Senmaida, Akagi Castle ruins, Tsuenomine, Doro Gorge, and Nunobiki Falls. First held in 2014, the event has staged 10 editions through 2025 and boasts a substantial pack on the trails, commanding a bigger field than 88% of 50k races globally while standing smaller than 12%.
The 10-hour limit sets an 11.5-minute-per-kilometer cutoff pace, creating a mid-pack standard that is tighter than 54% of 50k peers and more generous than 46%. That balance leaves reasonable headroom on technical ground before the December cutoff closes.
