American Oympic gold medallist Brooke Bennett led the way over the 10 kilometre course in the Round the Sound swim on Sunday.

Morgan Wolfe was the first male in the 10K as he was timed in two hours, 25 minutes and 59 seconds.

A total of 322 swimmers took part in the charity event, 315 of them finishing.

Competitors got the chance to tackle five distances — 10K, 7.25K, 4K, 2K and 0.8K

Three females grabbed the honours in the 7.25 race — Katharine Owen finished 2:01:18, followed by Jenny Wolfe (2:06:54) and then Darcy La (2:08:49).

Over 4K, Tyler Smith got home first in 56:01, more than four minutes ahead of Kirsten Read (1:00:36). CJ Hinckley was third in 1:02:21.
