Full 3.5-hour unedited race livestream of the 2025 Zinan Temple 99.9K Circuit Challenge! The biggest highlight is the self-made "CT Dynamic Data Live Broadcasting System," which overlays real-time speed, cadence, power output, and gradient changes onto the footage. Right after the start, the feed cuts to the lead group for a high-speed chase lasting 20 kilometers, where the first-person perspective and fluctuating power data give you a deep sense of the elite group's intense pulling rhythm. In the middle and later stages, facing Nantou's rolling hills and long climbs, the video authentically captures the rider's gear adjustments and mental struggle as fatigue sets in.
