Especially in tough economic times, running offers an affordable and positive way to relieve stress and gain a sense of accomplishment. Marathons and—more than ever—half-marathons are the ultimate achievement for runners and have experienced an unprecedented boom in the last several years.

New hunger for reliable information on marathon and half-marathon training, as well as new technologies that have revolutionized ordinary people’s ability to train intelligently, means the time is right for a new edition of longtime Runner’s World contributor Hal Higdon’s classic guide to taking the guesswork out of preparing for a marathon, whether it’s a reader’s first or fiftieth. Since its original publication in 1993, Higdon’s definitive manual has sold over a quarter of a million copies through all channels. The book is such a consistent seller for many reasons, but above and beyond all the others is this one: It works. At the core of the book remains Higdon’s clear and essential information on training, injury prevention, and nutrition. With more than 25 percent new material, this fourth edition of a running classic will be a must-own for both longtime runners and those new to the sport.

HAL HIGDON has contributed to Runner’s World longer than any other writer and is the author of 34 books. He ran eight times in the United States Olympic Trials and won four World Masters Championships. He is one of the founders of the Road Runners Club of America (RRCA).
