Setting off from Changliu Elementary School in the early morning, after warming up through Puli and Shuili, the ride officially cuts into Provincial Highway 21 on the New Central Cross-Island Highway, heading straight for Tataka Saddle. This trip adds Checheng and Dongpu as bonuses, totaling 120 kilometers with over 3,200 meters of climbing. The camera gives viewers a first look at the newly opened New Dongpu Tunnel, followed by a rapid elevation gain, temperatures dropping to 5 degrees Celsius, and the course enveloped in thick fog, like a fairyland. Facing the classic hellish section, the 'Zombie Slope,' with its relentless steep grades, riders push hard against the cold wind and lactic acid buildup, creating a visually stunning contrast between the freezing conditions and the majestic mountains.
