About this event
The Zengwen Reservoir Marathon is one of Taiwan's longest-running road races, tracing the shoreline roads of the island's largest reservoir in the hills between Tainan and Chiayi. AIMS lists the 2026 edition on Sunday 13 December 2026. The rolling, scenic course is a favourite winter target for southern runners escaping the summer heat. Full and shorter distances are staged from the reservoir recreation area.
