A father and son canoed for 23 miles for Great Ormond Street Hospital after a number of their friends and relatives died of cancer.
Tony, 57, and Peter Harsum, 35, got in a Canadian canoe for the first time and travelled from Godalming to Shepperton in Surrey on Saturday (August 9).
Speaking the afternoon before their trip, Tony, of Sunnymede, West Green, a body guard for some 15 years, said: “I’m quite excited about it – I suppose it’s like riding a bike – you either pedal or fall off.
“With everything I’ve done over the years I’ve come unscathed so it’s a question of putting something back.
“If we raised £1,000 it would be fantastic, hopefully a lot more.”
Tony said his parents died after contracting cancer.
His friend’s son, of Crawley, survived leukaemia and had been clear of the disease for around four years.
Tony said: “The family have been really supportive.
“We’re spreading out on Facebook and I’ve got some local sponsors.”
A number of Crawley businesses had pledged their support of the pair’s fundraiser.
The supporters included Barkers Taxi Service, Lloyds Barbers and author Casey Kelleher.
The pair hoped to complete the trip in less than eight hours.
Anticipating the challenge, Tony said he kept fit but had suffered “wear and tear” injuries over his career.
He had been involved in some 15 vehicle collisions.
Peter, of Eddington Hill, Broadfield, said he joined to support his father.
