With his historic win at the 2014 Boston Marathon, Meb Keflezighi cemented his legacy as one of the great champions of long-distance running. Runners everywhere wanted to know: How did someone two weeks shy of his 39th birthday - who had only the 15th best time going into the race and years of injuries and setbacks - run his personal best, and become the first American man to win Boston since 1983? For the first time, and in unprecedented detail, Meb reveals his complete training program in his new book, Meb For Mortals: How to Run, Eat and Think like a Champion Marathoner in which he instructs everyday runners how to put into practice the training, nutritional, and mental principles that have guided Meb through his long career.
