International Ice Swimming Association
The International Ice Swimming Association (or IISA) is an extreme swimming governing body that was founded by Ram Barkai to conduct and govern extreme cold water swimming events (e.g., ice miles) where the maximum water temperature is 41°F (5°C) and wetsuits are not allowed. It was selected as the 2013 World Open Water Swimming Offering of the Year. The IISA oversees and ratifies Ice swims all over the world including England (British Ice Swimming Championships in Windermere) and Ireland (Ireland Ice Swimming Championships). Its Fraserburg event is one of the World's Top 100 Open Water Swims. The IISA organizes and sanctions the Ice Cup or International Ice Swimming Association World Cup circuit.
