Formosa Trail is a trail ultramarathon held on the mountain trails of Puli in central Taiwan, featuring multiple distances including a challenging 104km ultra.
What this race demands
The Formosa Trail 104 km ultramarathon demands profound endurance to sustain forward progress across a continuous mountain trail distance without a stated elevation profile.
Extended Distance
Covering 104 kilometers requires deep aerobic conditioning and pacing discipline to manage energy expenditure over many hours of continuous movement.
Terrain Adaptability
Racing on mountain trails in central Taiwan necessitates technical agility and lower-leg resilience to handle uneven surfaces and sustained changes in grade.
Given the ultra-distance format lasting well beyond two and a half hours, athletes should target 60 to 90 grams of carbohydrates per hour to maintain glycogen stores and energy levels.
