Thousands of Swimmers Take on Taiwan’s Sun Moon Lake

Horns Blair in central Taiwan, signalling the start of an epic swimming event. Now in its 44th year, the Sun Moon Lake International Swimming Carnival drew more than 21,000 swimmers from over 30 countries, who braved a roughly three-kilometre swim across one of the country's most picturesque sights. But with more than 20,000 people in the water at once, safety is a major challenge. This year, organisers deployed boats and aerial surveillance, and introduced a new two-chip tracking system. Officials say the real-time tracking system, combined with professional water rescue teams, should improve safety monitoring and search and rescue efficiency, helping authorities keep track of thousands of swimmers during the cross-lake challenge.
