The first person to travel around the world on a unicycle

The first person to travel around the world on a unicycle will be joined by cycling champ Mark Beaumont as he starts his final leg.

Ed Pratt, who has peddled 18,000 miles across four continents on one wheel, has today (Thur) begun the final 500 miles of his three-year journey.

The 22-year-old was joint by record-breaking Scot cyclist Mark Beaumont as he left Edinburgh and headed for Chilthorne Domer, Somerset.
