ROCKIN 48 km 2026
Also known as: MYOKO TRAIL
Set in Myoko-Togakushi Renzan National Park on the Niigata-Nagano border, it loops from the Ikenotaira Onsen area past Naena Falls, Sasagamine and the Yumemidaira trail. The course is built for speed, and in early summer Naena Falls runs high with snowmelt.
The course tops out at 1,387 m (low point 672 m). The main climb comes early on: 690 m around 6–18 km. About 40% of the distance is gentle (under 5% grade). The median finish was about 7 h.
