In 2003, Joe Henderson released the second edition of his book Marathon Training. He based it on his long experience as a runner (marathoner since the 1960s) and writer (longtime columnist for Runner's World). But at the time of that book's publication he had never coached marathoners directly. That was about to change. Since 2005, he has coached a team of runners training for marathons and half-marathons, and now he details that experience in the book Team Training.
