淳安界首体育中心（小轮车赛场）

The BMX racing track at Chunan Jieshou Sports Centre sits in Yanjia village, Jieshou township, Chunan county, laid out around the velodrome as one of the five temporary venues of the Hangzhou Asian Games cluster, with a start area, the track itself, a competition zone and a warm-up area. Built to the UCI BMX racing standard, the course is about 400 m long and combines a starting ramp, jumps, rollers and several bends; the start hill's height and gradient follow world-championship practice, so riders launch from an elevated gate and spend well under a minute per run jumping, carving and overtaking on a constantly undulating surface. On 1 October 2023 the venue decided the men's and women's BMX racing events, two gold medals and the last cycling competition of the Chunan programme. The track is cut into the hillside above Qiandao Lake, with spectator areas along both sides that put the riders' airtime within close view. After the Games it passed to the Jieshou sports centre for unified operation and continues to stage national BMX championships, youth training camps and public taster sessions, forming a cycling base together with the velodrome and the mountain-bike course. Drivers reach Jieshou from Hangzhou via the Hangxinjing expressway and the lakeside ring road, and the township is about half an hour from Qiandao Lake town, with the Asian Games village and its supporting accommodation available for training camps and events. BMX racing has been an Olympic discipline since Beijing 2008, and the Chunan course is one of the few UCI-standard BMX tracks in Zhejiang, built with a permanent start hill so that it can be used outside the Games period.
