Run stronger and race faster by training slower. Respected running expert Matt Fitzgerald explains how the 80/20 running program—in which you do 80 percent of runs at a lower intensity and just 20 percent at a higher intensity—is the best change runners of all abilities can make to improve their performance. A hands-on guide for runners of all levels with training programs for 5K, 10K, half-marathon, and marathon distances.
