In November 1998, in Punta Arenas, Chile, 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 return to Britain in 2011. It is a challenge of epic proportions—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, 25 countries, a frozen sea, six deserts, and seven mountain ranges. Just one man, two feet, and an unstoppable determination. Giant Steps is Karl's diary of the first part of his trip: trekking from one end of the Americas to the other. Raw and revealing, it is an awe-inspiring account of adventure and human endurance.
