Formosa Trail 104K (Puli, Taiwan) 2026
Also known as: Formosa Ultra-Trail
Based in Puli, Nantou, in central Taiwan, it follows old Indigenous trails the organizers rediscovered on historical maps and have restored since 2016, crossing Mt. Wugonglun, Guantou Mountain near Wushe, Wujie village and the Zhuoshe forest road through Atayal, Seediq and Bunun lands.
The course tops out at 2,017 m (low point 489 m). There are 3 big climbs: 1,181 m around 0–11 km; 1,386 m around 55–62 km; 849 m around 87–92 km. Only about 30% is gentle (under 5% grade); most of it is climbing or descending. The median finish was about 23 h, through one night.
