"There is no established technique for running. It was thousands of years from the time when cavemen attempted to draw running movements, before the cinema camera accurately analyzed the relation of arms and legs in motion. But this in itself has produced no great improvement in running. The human body is centuries in advance of the physiologist, and can perform an integration of heart, lungs and muscles which is too complex for the scientist to analyze. Improvement in running depends on continuous self-discipline by the athlete himself, on acute observation of his reactions to races and training, and above all on judgment, which he must learn for himself. The runner has to make his own decisions on the track—he has no coach there to help him. If a man coaches himself, then he has only himself to blame when he is beaten."
