The local resident has been forced to postpone the swim a number of times and the new date for the swim is Saturday, February 13.

Laura was due to swim from Palm Beach to Shelly Beach this weekend but it was cancelled due to dangerous sea conditions.

MND took someway away from Laura and her family, which is why she decided to do the epic swim.

"For this event, I chose to do a fundraiser with FightMND in memory of Keith Blackburn," she said.

"Keith was a close family friend of ours who sadly lost his life to MND in 2007."

MND is terminal, the nerves that control your body's movements stop working, rapidly disabling you from moving, speaking and ultimately breathing.

"I read that once someone is diagnosed with MND, they have an average of 27months life expectancy. It is so awful and there is no cure yet," she added.

Laura has some familiarity with the area she will be swimming in.

However, the February 13 swim brings another challenge.

"I have previously swum the Palm Beach to Whale Beach swim a couple of times, along with ocean swims at Newport, Collaroy, Freshwater and Manly. However I have never swum across all of them at once," she said.

"I have heard that there can be a bit of swell around Long Reef which can be a tough component of the swim.

"My fingers are crossed for the best conditions on the day; a nice Nor'easter, little swell and a current dragging me down to Shelly would be great."

When things get tough she knows where to get inspiration from.

"I know there will be times during my swim that I will need to push my mind and body through," she said.

"I will draw inspiration from the support of everyone who has backed me and donated to my fundraiser, and just to soak in and enjoy the experience of the event with my support team and everyone else in the water."

She is no stranger to ultramarathon swims having completed the 19.7 kilometre swim Rottnest Channel swim in 2018.

However, her preparation this time came with a few new challenges.

"The preparation for this ultramarathon swim has been tough for me but I feel I have done as well as I could to get to this point," she said.

"I started training about a year ago, from having a two-year break after swimming the Rottnest Channel swim in 2018.

"Although juggling the training with the restrictions of COVID 19, part-time work and my now 18-month old daughter Lindy, has certainly been challenging.

"I have enjoyed seeing my progress and am proud of my efforts. I try not to get too hard on myself, and just do the best that I can."

Training can be lonely but Laura has a wonderful support base.

"I mostly train by myself consisting of sessions at Ulladulla leisure centre, swimming laps of Mollymook beach and swimming with a resistance rope in our backyard pool," she said.

"I have had a lot of support from family, friends and the community whom without I wouldn't have been able to have this opportunity.

"I cannot thank those enough - especially my mum, Monica, partner Gavin and his mum Jacinta for taking care of Lindy while I trained, along with Kaye Beer for time keeping some of my training swims, Ken Banks and all the Mollymook beach swimmers.

"As you can see it's definitely been a team effort for the preparation."
