This 19.7 km open water swimming event demands exceptional endurance and continuous stroke efficiency over an extended endurance duration.
Distance endurance
The 19.7 km crossing requires prolonged muscular endurance and sustained cardiovascular output over many hours in open water.
Open water capability
Navigating a direct ocean crossing demands strong sighting skills, mental resilience, and the ability to maintain form without walls or rest.
