HUNDREDS of amateur athletes competed alongside Olympic, world and commonwealth champions Ky Hurst, Michael Klim, Susie O'Neill, Mel Gorman, Craig 'Crowie' Alexander and Courtney Atkinson at the Fujifilm Triathlon and Ocean Swim on Hamilton Island over the weekend.

The fifth edition of the event saw Ky Hurst narrowly take out the open men's 2km ocean swim on picturesque Whitehaven Beach in a time of 23:15, in front of Joshua Richardson on 23:16 and Jackson Van Der Zant on 23:21. This was Hurst's fourth win in as many years at the event.

Mel Gorman took out the 750m 'anything goes' race, her first since shoulder surgery just a few months ago.

Hurst said the Fujifilm Triathlon and Ocean Swim was on his "must do list" every year.

"Competing alongside the likes of Klim and O'Neill, along with amateurs and people just keen to give it a go, makes it a really unique event," he said.

Saturday's sprint triathlon on Hamilton Island was won by local Ryan Palazzi in a time of 01:08:44, with Elyse Foster taking the women's title just five minutes behind. Susie O'Neill's daughter Emma placed second, with Madame Butterfly herself placing fifth.

The unique course sees challengers tackle a 750m ocean swim across Catseye Bay, followed by a 20km cycle including laps of Hamilton Island's airport runway, before finishing with a 5km challenging hill run culminating in a beachside finish.

Olympic gold medallist Michael Klim's 'The Milk Men' team finished first in the men's team category, while Crowie and Atkinson's respective mixed teams failed to place.

The Whitehaven Beach Ocean Swim is the only sporting event permitted to be held in the waters off this world famous beach. Race lengths include 2km and 750m competitive races, as well as a 750m 'anything goes' and 350m kids event.
