Jason Lewis's journey is almost better defined by the mishaps than by its scale. It almost came to a premature end when he was pursued by a salt water crocodile in Australia and again after he was knocked over by an elderly driver as he rollerbladed across the US and almost lost a leg.
He was questioned as a spy in north Africa and has dodged more pirates and bandits than he cares to mention.
No yacht for him when he crossed oceans and seas - that feat was achieved in a cramped and battered pedal-powered boat.
And it is in that craft, after an expedition spanning 13 years, two months and 23 days that Lewis yesterday crossed the meridian line at Greenwich in south-east London and become the first person to circumnavigate the world using only the power of his own muscles.
