The one-percent theory is difficult to prove (and, therefore, not called the one-percent rule), but anecdotal information shows that the theory does seem to hold true. For every element you add to OR improve on in your training, you will improve your race time by 1 percent: Stretching, Allowing Recovery Days, Doing Circuits, Doing Workouts, Using Great Running Technique, Does Strides & Drills, Hydrating Well, Eating the Best Possible Foods, Using Energy Gels, and Getting Enough Sleep. Doing some of these can improve your time by far more than 1 percent, but the idea is that they all add up.
