As one of the youngest teams in this year's Rottnest Channel Swim, Zoe Davidson and her teenage teammates are more concerned about finishing than setting records.
But if their gruelling training regime is anything to go by, the Mercedes College students are certain to give other competitors a run for their money.
Zoe, Isabella Norrish, Aleisha Sleight and Kate Martin stepped up their training when they decided to swim in the race about a year ago.
The Cottesloe surf lifesavers meet four or five times a week for 30 minutes in the gym and two hours of laps in the pool.
Zoe said they noticed a big improvement in their swimming and enjoyed having a goal. "We have all been thinking about it for a long time and now we are all the right age so we just thought it would be a good experience and a fun thing to do," she said.
"With our experience in the surf club, we got a bit more confidence to do it as well."
Zoe, Isabella and Aleisha are 15 and Kate scrapes past the minimum age at 14. The girls will take turns swimming for about five minutes at a time in their bid to complete the 19.7km open water race course next month.
Zoe admitted their biggest fear was sea sickness and they would test ways to prevent it before the February 23 event."I feel like we are prepared, but we definitely have to keep the training up over the next few weeks," she said.
