In 2013, Australian Tom Denniss became the fastest person to circumnavigate the world on foot. His epic journey lasted nearly two years, and for each of the 622 days it took him to run around the planet, Tom completed the equivalent of a marathon or more. Based on distance alone his feat was an extraordinary act of endurance, but along the way Tom also survived a near - death experience on an ice cliff as he was running over the top of the Andes, was chased by dogs, snakes and suspicious border police, narrowly avoided lethal cars and buses, suffered in 60 - degree heat and sub - zero blizzards, tore through 17 pairs of runners, and raised tens of thousands of dollars for Oxfam. He also experienced an amazing diversity of scenery, culture, food and people as he traversed New Zealand, North and South America, Europe from the Atlantic to the Bosphorus, and Australia from Fremantle to Sydney. The World at My Feet is his account of an incredible 26,232 kilometre run, and a vivid insight into an adventure of truly global proportions.
