You complete a timed swim of 5 kilometers and/or 10 kilometers in a 50-meter pool of your choice, then submit your times online. Some people swim for competition - to compare themselves to other swimmers doing the same event, some for the challenge, some for fitness, and others do it for fun — all who wish to participate are welcome. Your submitted time determines the final order of finish.
