Race details
Distinctive features
- The 100.7K category is a 64-lap race on a 1.574 km loop, so mental rhythm and aid-station discipline matter more than in a point-to-point road race.
- The event also offers 42.5K, 22.04K, and 11.02K categories, with late-night or early-morning options for some shorter distances.
- Because the course stays around Eternal Golden Castle, support access is straightforward, but 100K runners still face repeated laps and humid Tainan night conditions.
Runner notes
- The 100.7K finish requires 64 laps. If loop races are mentally difficult for you, plan checkpoints such as every 8 or 16 laps for fueling and self-assessment.
- The race runs from evening into the next morning, and September nights in Tainan can still be humid; hydration, electrolytes, and clothing changes deserve early planning.
- The 42.5K, 22.04K, and 11.02K categories are also multiples of the same loop, so confirm whether your category starts in the evening, late night, or early morning.
