SURF LIFESAVING: A Sydney teeanger tagged as one of Australia's best up-and-coming ironwomen is targeting a feat achieved by Sunshine Coast legend Grant Kenny, when the open Australian Surf Lifesaving Championships starts on Thursday.

Lizzie Welborn, 18, has stated she'd like to repeat the historic double carried out by Kenny at Maroochydore at The Aussies in 1980, when he won the under-19 and open ironman races on the same afternoon.

"You don't have your whole life to do it so I'm running out of time,” she told Surf Life Saving Australia. 

"The double is definitely something I've been wanting to do. 

"I won the under-17 Ironwoman last year and tried to back up and do the open so I almost got there and I'll try again this year. 

"It's an amazing goal to have to put yourself up there with Grant Kenny, but it's a hard thing to do.”

At 53, Kenny is still going strong in the surf. 

On Monday, he paddled backwards on his way to winning the 50-54 ironman at the Australian Masters, at North Kirra on the Gold Coast.
