Life cycle

A four-year-old boy and his father are attempting to break into the record books by cycling the length of Britain.

Henry and Adrian Cole, from Winscombe, Somerset, are two thirds of the way through the 874-mile trek from Land's End to John O'Groats.

Adrian, 35, an accountant, is doing most of the pedalling on the pair's converted tandem bicycle.

But when they cross the finish line in June, Henry will become the youngest person to complete the challenge.

The father and son's journey began in August last year, but because of Mr Cole's job it has been split into three parts.

The pair have already cycled 500 miles up the length of England, and are now preparing for the final, Scottish section, which will begin later this month. They cover an average of 30 miles a day with Henry pedalling a trailer cycle attached to the back of his father's bike.

Henry's mum Sara, 38, follows behind in a car which doubles as a supply vehicle.

Mr Cole said: "Henry just loves it, no matter how many miles we've covered he carries on pedalling away with a grin on his face. "Although he is not on a separate bicycle his little legs never stop pushing so he is always contributing to the forward propulsion of the bike."

The pair are raising money for Bristol-based head injury charity Headway and the St. Mary's Church, Langford PowerHouse Project.
