淳安界首体育中心（公路自行车赛场）

The road cycling course of the Chunan Jieshou Sports Centre lies in Jieshou township, Chunan county, Hangzhou, one of five temporary outdoor competition venues in the cluster, with both the start and the finish at the lakeside sports centre. The race borrows the county's lakeside public roads: the men's route runs 207.7 km, almost exactly one lap of Qiandao Lake, and the women's route 142 km, passing through 14 townships and linking the Chunyang Highway and Chunkai Line, two roads officially rated among China's most beautiful rural routes. The course has 37 bridges, 30 tunnels and 1,071 junctions, varies in width, and mixes flat sections with climbs, descents and sharp bends; its highest point sits at about 342 m, which is why the event is called the marathon of road cycling and why it was the longest route at the Hangzhou Asian Games. From 3 to 5 October 2023 the venue staged the men's road race, men's time trial, women's road race and women's time trial, producing four gold medals. The whole Jieshou cluster covers about 8.4 sq km, split evenly between land and water, and apart from the permanent velodrome every outdoor venue was built as a temporary installation. After the Games the lakeside circuit continues to host the Tour of Qiandao Lake, the Hello100 series and mass rides, feeding steady traffic to guesthouses, orchards and scenic spots in the riverside townships and anchoring the lake's sports-tourism economy. In June 2023 the same roads hosted the national road championships as the Asian Games test event, and on race days the circuit is closed to traffic, with team buses and warm-up loops based at the sports centre beside the athletes' village.
