A Kingston CEO is hoping a punishing 14km swim will raise £10,000 for disabled children.

Michael Byrne, chief executive of a construction industry group, will compete in the Thames Marathon in aid of Caudwell Children, which provides practical and emotional support to disabled children and their families.

The 45-year-old, despite having no connection with disability, said he discovered the charity online and was compelled to fundraise for them.

He said: "The work they do is incredible. Once I saw the assistance they give to disabled children and their families I was hooked."

No stranger to the Thames Marathon, the father of five completed the challenge last year - he said he will be happy if he avoids swallowing quite as much water as last time.

His training to prepare for the race, on August 5, currently involves swimming several miles three times a week and going to the gym three times a week.

An initial target of four hours "may prove to be more difficult," said Mr Byrne, after he tore his calf in a skiing accident that left him with a blood clot and slowed his training down.

Caudwell Children has supported more than 25,000 families since 2000, by providing equipment, in-hospital or home support, treatment, therapy and short and long trips - including to Disney World - for children with life-limiting conditions.

Head of events Kerrie Davies said she was delighted by Mr Byrne's support, and wished him every success in his challenge.
