24 year old Tom and 22 year old Sam Hutton are now in training for the London Marathon, aiming to raise £15,000 for the rescue services who tried to save their brother.
Last October, they took part in the Great South Run raising over £5,000 and they also plan to do a 14km Thames swim in August.
Tom, 24, a trainee lawyer, said, “The RNLI were absolutely amazing in their efforts and we want to show our appreciation by raising money for a fantastic charity devoted to saving the lives of people at sea.”
