Nick Butter, 30, set a world record after running 26.2 miles in 196 countries recognised by the United Nations. He completed his final journey in Athens, Greece, on Sunday.
Mr Butter quit his banking job to embark on his solo expedition in January last year after being inspired by a friend with terminal cancer.
He has since covered 5,130 miles in organised events across seven continents, overcoming the extreme heat of the Sahara Desert and bitter cold of Antarctica.
During the 675-day adventure he has been hit by a car, bitten by a dog, broken his elbow and even been shot at. He hopes to raise a total of 250,000 for Prostate Cancer UK.
