Royal Marines from around the country will descend on Dorset tomorrow for an epic challenge to help fund a baby boy's medical bills.

Cameron MacRae, son of Bovington-based Royal Marine Andy, was born in August 2022 with infantile leukodystrophy, a rare condition that affects the brain's ability to function with a progressive loss of physical and mental capacity.

Due to the rare nature of baby Cameron’s condition, the family - currently being supported by The Royal Marines Charity - has had to find a large amount of money for surgery and the follow-up care needed for treatment.

Although Cameron’s life expectancy remains short, this treatment will give them the chance to be a family and savour the time they have together for as long as possible.

More than £15,000 has been raised for his treatment so far.

Cameron's father Andy has been a proud member of the Royal Marines since 2006 and has served operationally in various countries around the world.

He is currently based with the Armoured Support Group at Bovington Garrison which is organising and running a 24-hour endurance relay race along the notorious South West Coast Path around Lulworth called the 'Rollercoaster'

The race is the brainchild of Corporal Mike Dowd who says the route of the Rollercoaster race will follow the steep path along a challenging 86km part of the steeply undulating path from Lulworth Cove to The Obelisk and back, a total climb of 620m.

Royal Marine Commandos from around the country will compete in the challenge on Thursday.

Cpl Dowd said: "We want to do everything we can to support fellow Royal Marine Andy and his partner Hannah.

"We have done this by melding support for Cam with our ongoing Commando training to maintain individual and team fitness to move at distance over all terrain."

Any support or donations are greatly appreciated and can be made via the gofundme.com website.

The family will be donating additional funds raised to The Royal Marines Charity, Krabble UK, and South West Children's Hospice.
