Running is one of the few activities that reveals the way in which primal instinctive repetition cannot be replaced by any amount of science or emotion or tactics. In the face of such a basic, cumulative, natural process all technology, passion, and trick will fall short. Keep It Simple Stupid. The only way to get to the finish line is by taking one more step, and then another until eventually you cover it. Not one step that can be skipped. So do the miles. And look forward to the speed.
