淳安界首体育中心（自行车馆）

The velodrome at Chunan Jieshou Sports Centre stands on the shore of Qiandao Lake in Jieshou township, Chunan county, the main building of the Chunan Asian Games village and the only permanent new venue in the cluster. Its design concept, sunrise, leaping fish and the pearl of a thousand islands, shapes the roof and facade with fishing-culture motifs, so the building reads from a distance as a pearl set in the landscape or as ripples spreading from a fish breaking the surface. It covers a 9,700 sqm footprint with 24,282 sqm of floor area and rises 40 m; the elliptical roof spans 132 m on its long axis and 101 m on its short axis, with a 32 m canopy over a stiffened single-layer lattice shell erected by inner-ring integral lifting, the longest steel span ever built in Chunan. Inside are a 250 m standard indoor track, 3,040 spectator seats, competition and warm-up areas, athletes' facilities and media workspace. From 26 to 29 September 2023 the venue staged the 12 track cycling events of the Hangzhou Asian Games, producing 12 gold medals. After the Games it continues to host national track championships, national and provincial squad training, public ride sessions and youth coaching, and together with the outdoor road, mountain-bike and BMX courses it forms a complete cycling base about half an hour by road from Chunan county town along the lakeside highway. As the main building of the Asian Games village it anchored the athletes' compound during the Games, and its 250 m track is the standard length for international track cycling. Across four days the track decided 12 medal events, among them team pursuit, madison, keirin and individual sprint.
