World Open Water Swimming Federation Ratification

• The World Open Water Swimming Federation defined and ratified the Yukon River Swim as a solo, assisted, escorted, non-stop marathon swim down the Yukon River in the Yukon Territory of western Canada.
• The swim was deemed assisted because Edgley wore performance-enhancing non-standard equipment throughout the swim (i.e., wetsuit,neoprene hoodie, neoprene gloves, and neoprene booties) that benefitted his speed, aided in his buoyancy, and increased his heat retention throughout the swim. This performance-enhancing non-standard equipment was necessary due to low water and air temperatures for safety purposes.
