"My 27km ultramarathon swim will be in recognition of the 27-month life expectancy for someone diagnosed with motor neuron disease (MND)," she said.

"This ocean swim will take me between eight and nine hours,

"However, it will only take you a few short minutes if you wish to contribute a donation to help us fight MND together."

Laura, this month, will swim from Palm Beach to Shelly Beach [South of Manly] and she is up for the challenge because she has set her sights on raining much-needed funds for MND.

Her gaol is $10 000 and so far has raised $6,486.

Go here to support Laura.

Donations over $2 are tax-deductible and can be made direct to FightMND on their secure website.

Meanwhile, swimming can be a lonely sport but during a recent training swim, Laura was overwhelmed with the support she received.

Some people got in the water to swim with her, others provided support on stand up paddle and surfboards.

Arriving home at the conclusion of 20 kms, over six hours in the water, swimming in what turned out to be in difficult conditions, there were Lloyd and Ruth, Sue, Kaye and Monica, all present to share with Laura, in her remarkable achievement.

Laura was lost for words trying to explain her gratitude for all the swimmers who turned up throughout the morning to make this such a memorable occasion for her.

"Although the swimmers are a motley crew in some regards, an odd assortment of people who are largely drawn together through their common love for the ocean, its time like these when you see the beautiful caring nature become so evident in many of the swim group, chipping in as best they can to help out a friend," Laura said.

Laura was as overwhelmed with gratitude.

"Thanks to all the swimmers who contributed. It was a beautiful day," she added
