This event has four swim distances to choose from, 1.2km, 2.5km and 5km open water swim.
The WOW Challenge is for everyone from champions, weekend warriors, kids, multiclass swimmers, fast, slow, young and old swimmers.
It’s also an opportunity to mingle with some of the best open water swimmers in the world with past winners including 2015 World Champion Jordan Wilimovsky, Team USA’s Katy Campbell, Australian Dolphin Sam Sheppard and Brazilian Olympian Lisandra De Carvalho.
This swim starts on the beach before swimmers head out to round two buoys before returning to shore to finish.
