The 44th Sun Moon Lake International Swimming Festival was held on September 20, 2026, in Nantou County, attracting approximately 21,700 participants from 38 countries.

To improve safety, organizers implemented a new “real-name dual-chip” sensing system. This required swimmers to wear specialized chips on both their wrists and torpedo buoys to allow for real-time movement monitoring and efficient location identification during emergencies.

During the event, Spanish swimmer Zhao Weixin recorded the fastest time, completing the nearly 3-kilometer course in 56 minutes and 27 seconds. To promote ecological sustainability, Nantou County Magistrate Xu Shu-hua released 10,000 fish fry into the lake. The festival also introduced commemorative medals for finishers to supplement traditional certificates.
