Late November in Puli and the surrounding Nantou mountains brings cool, generally stable conditions. Daytime temperatures near the start at 500m elevation run 15–20°C, but mountain sections reach 1500–2000m where it is significantly colder. Nights drop below 10°C and can approach freezing at higher elevations. With a 4AM start, 104km runners spend multiple hours in cold darkness before dawn. A waterproof jacket is mandatory; a mid-layer in the cpD drop bag is strongly recommended for slower runners. The post-typhoon November season is drier than summer, but mountain weather can change rapidly. Open ridgeline sections between cpB and the upper course have significant UV exposure during mid-race daylight hours.
Temperatures drop well below 10°C at elevation overnight. Waterproof jacket mandatory; mid-layer recommended in cpD drop bag for slower runners.
Exposed ridgeline sections in mid-course have significant sun exposure; sunscreen and hat recommended.
Mountain conditions can change rapidly; race-day weather in Puli does not reflect conditions at elevation.
