description Ice Swimming Overview
Ice swimming is an extreme endurance sport where athletes swim in water temperatures of 5 degrees Celsius or below, typically without wetsuits. Events often take place in 25-meter pools cut into frozen lakes or rivers, requiring competitors to navigate freezing water while maintaining racing speeds. Governed by the International Ice Swimming Association (IISA), the sport features specific standardized distances, including the Ice Mile and the Ice Kilometer. It appeals to open-water swimmers seeking high-adrenaline cold-water challenges and physiological endurance tests.
