In Punta Arenas, Chile, in November 1998, Karl Bushby set out on one of the most remarkable journeys of modern times. His plan is as simple as it is extraordinary: to walk up the Americas, across the Bering Strait, through Asia, Russia and Europe, back through the Channel Tunnel and returning to Britain in 2011.

It is a journey of remarkable endurance -- 20 miles a day, 3,000 miles a year, 36,000 miles in total. By the time Karl returns, he will have crossed four continents, twenty-five countries, a frozen sea, six deserts and seven mountain ranges.

But more than that, unlike other similar expeditions, Karl is attempting it single-handed: no huge support teams, no large sponsorship deals, this is the inspiring true story of a man facing remarkable odds -- and winning.
