The swim course is triangular, starting at the beach by Hemingway’s, marked by large buoys at each point and smaller markers defining the edges, going in a clockwise direction. Sometimes swimmers get confused at the turns, so it’s common to have to point out the correct direction.
There are multiple waves of swimmers (up to 4) to help spread the legs and arms a bit.
The water is pretty shallow here, so most swimmers can always just stand and walk if they had to. However, if they are exiting the race, they must exit via a power boat, taken to the Did Not Finish (DNF) dock, for accountability.
