Memories of the brother who died in a boating accident are spurring on a runner during every kilometre of his 772km challenge – one kilometre for every week his sibling was alive.

Charlie Hutton was just 14 when he died after being hit by a wave and swept onto the spinning propeller of a boat while on holiday on the Dorset coast in July 2012.

And since then his brothers Sam and Tom have kept his memory alive by completing fundraising challenges to raise money for the RNLI.

Collectively Team Hutton has raised almost £20,000 for the charity and 23-year-old Sam hopes Challenge Charlie will bring in thousands more.

He started the challenge on June 16 and will end it on September 20, which would have been the Whitgift School pupil's 17th birthday.

The 97 days equates to 14 weeks and each week ends with a 14km run, 1km for each of the 14 years that he lived.

Charlie, who lived with his family in South Croydon, had been a talented hockey player with his eye on a place in the Great Britain team by the 2020 Olympics.

And his brother Sam said if he was here he would pushing him to run more.

The marketing executive said: “When I’m about to go out for the run I think about Charlie and the reason why I’m doing it.

“If he was here I think he would be constantly pushing me to go faster and saying catch up.

“He would be constantly competitive.”

Team Hutton’s first fundraiser was the BUPA Great South Run in October 2012 and since then they have completed other sporting events including the London Marathon and a half ironman.

Sam, of Nepaul Road, Battersea, said doing these challenges has helped the brothers.

He said: “If the fundraising wasn’t there I would feel a void.

“The world has lost an amazing person and the best way I can see it is to try to make up for what has been lost.

“I’m trying to keep his memory alive and I do the challenges to remind everyone of what we have lost.

“The only reason Challenge Charlie is doing so well is because people loved Charlie so much.

“I would love as many people to join me as possible and if people want to go out running they can and people can buy a t-shirt and get their friends to go out and run with them for Charlie.

“That would be the dream, to have people I don’t know running for Challenge Charlie.”
