The Clean Half is modeled after the world famous Maui Channel Crossing Relay Swim where teams of 6 people swim 10 miles across the dark blue Lanai Channel. In the case of the Clean Half, each team had 5 people, either of all the same sex, or mixed teams. Since the race is a relay, the entire event involves “leapfrogging” from one swimmer to the next, allowing for maximum performance for a short period of time, and then giving a chance for the swimmer to recharge on the boat before returning to the sea. In the first rotation of swimmers, each person was bound to swim 20 minute-legs before changing to the next swimmer. Thereafter, each swimmer swam 10 minute-legs. This race is based on time periods of each swim, not on the distance each swimmer covers, as that would be impossible to monitor in an ocean event.
