James Ketchell rows, climbs and cycles around the world

After a motorcycle crash in 2007, James Ketchell was told by doctors that his ability to walk could be impaired.

But he wanted to prove them wrong. He decided to take on what has been described as the world's toughest triathlon, and earned himself a place in the record books in the process.

He rowed 3,000 miles across the Atlantic, climbed to the summit of Everest, and cycled around the world unaided.
