Setting off at dawn from Qixingtan Beach in Hualien, the riders cruise at high speed along Provincial Highway 9 in the morning light, then cut onto Provincial Highway 8, the Central Cross-Island Highway. The footage passes through Taroko's magnificent canyon cliffs and a series of tunnels, and as altitude gradually increases, the route pushes from Tianxiang and Xinbaiyang up to the alpine coniferous forests of Bilu Sacred Tree. The video details pacing strategies for long, high-altitude climbs, timed nutrition intake, and cadence control and muscle fatigue management on sustained steep gradients. As the race reaches the brutal section after Dayuling, where thin oxygen and double-digit gradients hit simultaneously, how can the remaining energy be rationed to fight to the finish?
