Taipei's road cycling holy land, 'Waishuangxi Zhongshe Road,' has always been the standard test for cyclists' climbing abilities. After six months of solid self-training and body management, successfully shedding 14 kilograms, CT Yeh returns to this familiar winding mountain road for a timed post-test. The camera, in a subjective perspective, weaves through the quiet night dotted with dim streetlights, while the screen simultaneously displays real-time heart rate, cadence, and speed data from the bike computer. Facing the relentless series of gentle and steep slopes on Zhongshe Road, the lightness of pedaling and the rhythm of cornering feel entirely different without the burden of 14 kilograms. In this self-competitive night climb test, just how significant an evolution in fitness will it reveal?
