Jim Knaub started out as a pole vaulter and made it to the Olympic Trials. Then, after getting hit by a car while on his motorcycle and becoming a paraplegic, he re-invented the sport of wheelchair racing and won the Boston Marathon five times and the Los Angeles Marathon three times. In his mind, though, his most important victories came when he was able to motivate others to get back into the game of life after trauma. Jim Knaub is a true legend of endurance sports and is always a great interview.
