Course and logistics
The swim takes place in a sheltered cove to reduce wave exposure. Spectators can walk along the shoreline to view athletes. There is plenty of parking close to the transition area. Check-in requires a photo ID. Athletes may not enter the transition area until they have checked in and have their bib number. A prerace meeting is held in the transition area and the transition area closes before racing begins. Bike and run courses are mapped by the organizer.
