Cover of Cross the Lines: A Journey to Complete the Marathon Grand Slam At age 42, William Thomas decided to take up running for the first time in his life, with a goal of running a marathon. A couple years later, he had a new goal: to complete The Marathon Grand Slam, which consists of completing a marathon on all 7 continents and at the North Pole. Over the years that followed his journey took him to Singapore, France, Brazil, South Africa, Australia, Antarctica, and, in 2016, to the North Pole. CROSS THE LINES is the story of this journey, not just the races but also the lessons he learned along the way, lessons that can help not only in running but also in business, leadership, and in all aspects of life.
