The five friends – Ben Rickhuss, Nigel Capewell, Ben Griffin, Andy Tate and David Powers – completed a Channel-length sponsored swim in support of the appeal. swimming 21 miles between them in a little more than 12 hours, starting at 8am and finishing at 8.10pm.
“We are very grateful to the staff at the sports centre who were very supportive throughout the day and to the people who came to cheer us on and the many others who have sponsored us,” said Andy Tate.
Caroline said: “I am in awe of the guys have done and cannot thank them enough for all their hard work and effort!”
