Cyclist Alastair Humphreys is returning to the UK tonight after completing his epic four-year journey around the world.
The final leg of Mr Humphreys' solo journey will be a cross-channel ferry from France, after a bike ride that took him 45,000 miles across five continents and through 60 countries.

While his machine is nominally the one he set out on, he has cycled his way through five new wheels, 15 sets of tyres and three new bicycle frames. His worst record for punctures was set in Bolivia - 15 in one frustrating day; although the final stages in Europe have not proved plain sailing. Last week in the Dolomites, he reported "15 punctures in four days, four broken chains, two buckled wheels, a split tyre, a fragile bottom bracket, no back brake, six broken spokes in a cracked rim and split hub and only about 10 gears still working out of 27".
