This weekend's State Bay of Islands Classic in Paihia seems to be getting more and more popular as the event has increased by 16 per cent on last year's numbers.
In all, 930 swimmers will compete in this weekend's races, which doubles as the second in a six-race series around the country this summer.
The final four rounds will be held in the New Year in Wellington, Akaroa, Mount Maunganui and on Auckland's North Shore.
This weekend's race is a 3.3km swim from Russell to Paihia, with Aucklander Phillip Ryan being one of the favourites.
"I love swimming the Bay of Islands race. It's exhilarating swimming across the bay and I'm really looking forward to it," he said.
