This trail running event guides athletes through lush forests and dramatic mountain ridgelines around the iconic Shihmen Reservoir in Taoyuan.
What this race demands
This 50-kilometer trail running event requires sustained endurance over nearly 3,000 meters of climbing across mountain ridgelines and forest trails in December.
Climbing volume
Accumulating 2,824 meters of elevation gain over a 50-kilometer distance demands significant vertical resilience and specific preparation for steep ascents and descents.
Muscular durability
Navigating technical mountain ridgelines and forest terrain for an extended duration places high repetitive load on the lower limbs.
Aerobic endurance
The considerable distance and elevation profile require a well-developed aerobic base to sustain forward motion over many hours.
A sustained effort of this duration requires consistent carbohydrate intake of 60 to 90 grams per hour to maintain energy levels.
Estimated finish times
