British ultra-athlete Rob Pope left his job to recreate Forrest Gump's fictional run, traversing America five times.
The English veterinarian is the first person to complete the epic run covering 15,600 miles, or 25,000 kilometres.
It took him 18 months and raised money for the World Wildlife Fund and Peace Direct.
He's no stranger to endurance events and holds the Guinness World Record for the fastest marathon, dressed as a film character.
Rob Pope now has a podcast - "How to be Superhuman".
His memoir Becoming Forrest - one man's epic run across America catalogues the ins and outs of his endurance run, the injuries, stamina sapping days, forest fires, wildlife and wild weather, and also a marriage proposal.
