Kevin Carr ran the equivalent of a marathon a day as he jogged his way through 26 different countries over 621 days.
The challenge saw him run across Europe, India, Australia, New Zealand, Canada, America, South America and Ireland.
Along the way he came face to face with snakes, scorpions, wild dogs, wolves, bears and mountain lions.
He covered the distance with just a trailer of supplies to help him on his way.
