淳安界首体育中心（游泳赛场）

The swimming venue of Chunan Jieshou Sports Centre is the open-water course of the Hangzhou Asian Games, lying south of the centre of the Chunan Asian Games village in Jieshou township, Chunan county, with separate racing and warm-up water areas as one of the cluster's five temporary venues. It uses Qiandao Lake directly: the lake district is mountainous but gently sloped, the water is broad and fed by a dense river network, and the body is classed as national grade-one water, known as the finest water under heaven, with clarity and temperature well suited to long-distance open-water racing. On 6 and 7 October 2023 the venue staged the men's and women's 10 km marathon swims, two gold medals; Zhang Ziyang won the men's race in 1:55:45.8 and Lan Tianchen took silver 0.4 seconds behind. Chunan holds open-water events every year, and the May 2023 Qiandao Lake open-water swimming meet drew 171 teams and more than 3,500 swimmers, with over 8,000 visitors watching and travelling; the meet returned to Chunan in September 2024. The venue is a temporary installation with a start pontoon, buoyed course, timing systems and rescue boats, and after the Games it keeps its open-water and watersports function, sharing shoreline and water with the triathlon venue to anchor the lake's summer watersports season. The venue sits inside the 8.4 sq km Jieshou cluster, half land and half water, next to the triathlon course and the Asian Games village, and is reached from Qiandao Lake town along the lakeside ring road. Marathon swimming closed the Games' open-water programme on 6 and 7 October 2023, in the final week of the Hangzhou 2022 schedule.
