Weighing 250 pounds, a pack a day smoker and a heavy drinker, Dion Leonard's life changed one night after he made a drunken bet with a friend on who could run a half marathon race the quickest. From not being able to run around the block, Dion has since gone on to become one of the most competitive ultra runners in the world competing and completing some of the worlds toughest races across the planets most extreme and inhospitable locations. 










Dion has tested, pushed, broken and set new limits running across formidable landscapes from inhospitable deserts, high altitude mountains to wild jungles. From 100 miles to 240 miles non stop, Dion has rebuilt his mental and physical limits in search of the ultra high, to find himself and to become the best he can be.. Dion's journey from fat to fit has inspired people all around the world to take up running and his influence has encouraged many to push their own boundaries to find themselves and achieve what they didn't think was possible.
