Barrie and David Searle rode from George to Cape Town and discovered that age and experience have their advantages and disadvantages when it comes to endurance.

Manchester Grammar School sixth-form pupil David, 16, said: "Dad was pretty steady when it came to riding, by that I mean he was consistently at the back of pack.

"But I don't think he suffered quite as badly as me. After one marathon stint I had to be prized off the saddle, as my muscles were so sore."

The brave duo raised the money for London-based Norwood, which helps the socially disadvantaged and those with learning difficulties.

David added: "We did quite a bit of training together before we flew out, in the gym and across Cheshire, but it doesn't prepare you for cycling 50 miles each day."

And David and his dad encountered those who live in many of South Africa's poor townships.

He said: "The ride covered some of the most scenic landscapes in South Africa with breathtaking vistas at every point.

"We had a chance to go to the townships and see how the vast majority of South Africans still live in abject poverty.

"There were families of eight or nine living in a single corrugated iron shack with just one room.

"It made me realise just how lucky I am and made me even more determined to continue to work for charity throughout my life."

Yeshurun Hebrew Congregation member Barrie has previously completed three other long distance cycle rides for Norwood.

The 55-year-old barrister said: "It is important that everyone appreciates their own good health.

"I am sure David now has a better understanding of disability after seeing six Downs Syndrome fellow riders on tandems with their carers."

The Searle cycling team are planning another trip to India next year - and this time hope to make it a threesome with 15-year-old younger son, Aaron.
