What runner doesn't hope to compete in, and complete, a marathon? This 16-week program developed by nine-time New York City Marathon winner Grete Waitz--and used by her to train both amateurs and professionals for the biggest races--can make that dream come true. Written in an efficient and useful style, and featuring more than 50 photos, it discusses base fitness, stretching, proper posture, and staying healthy through it all, as well as how personality and motivation affect training. Waitz also covers the most current and cutting-edge trends in long distance running, including cross training with yoga, Pilates, and deep water running. There's also a special 30-minute beginner's program as well as advice specifically tailored to first-time marathoners over 40 years old.
