The Runner's World Advanced Running Book is not your basic running book. It goes well beyond the fundamentals and delves into such fascinating areas as physiology, interval training and race strategy. It picks up where other running books leave off. Rather than just explaining how to run, the Runner's World Advanced Running Book tells you how you can run farther and faster, how you improve performance by supplementing your diet with the right vitamins, how the world's best runners pace themselves to record times.
