This week I interviewed Dr. Phi Maffetone (July 22, 2008). The focus of the interview is on using his principles to train for longer events, marathons and ultra marathons. There is also a discussion on nutrition, avoiding stress and injury, exceeding MAHR during races, and what he is doing these days.
