On 31 December 2011, Australian Tom Denniss took two years off from his successful business career to take on a remarkable challenge. He embarked upon a run around the world. A run that would take more than 20 months, and cover over 26,000 km. In simple terms, running the equivalent of 622 marathons in an equivalent number of days. Beginning at Sydney's Opera House, Tom headed east, across five continents, crossing the Rockies and the Andes, as well as deserts like the Nullarbor before finishing at precisely the same place on 13 September 2013-the fastest ever circumnavigation of the Earth on foot. In The World at My Feet, he shares his fascinating and sometimes frightening experiences along the way, with insights and anecdotes from all over the world-all at a pace which allows you to really appreciate the experience.
