“More than distance runs or faster repetitions, marathon-pace training increases aerobic energy production in slow-twitch cells, builds more capillaries to carry more oxygen to these cells, improves the cells’ ability to export lactate and to reduce acidity, and leads to better running economy-the equivalent of better gas mileage in a car.” “Marathon-pace training is simply one of the best workouts there is for improving the endurance capacity of your slow-twitch, endurance muscle cells,” says Pete Magill, a South Pasadena, California-based coach and author of Build Your Running Body.

After all, good training programs for all other distances include regular work at goal race pace, so why should the marathon be exempt? In a marathon build-up, race-pace workouts not only prepare you physically and mentally to hold a good pace for 26.2 miles. These workouts make obvious sense for marathoners. In recent years, many runners have added to their marathon training an element long used by elites-frequent runs at marathon race pace, either as a stand-alone workout or in the second half of a long run.
