This concept is critical: The actions of Ritzenhein’s body told him he could run some spectacular races, and sure enough he went out and did exactly what his body told him it could do. Confidence is not some nonphysical quality snatched from the spiritual dimension and installed in the mind. It is the feeling that arises when the body’s knowledge of itself is in harmony with a person’s dreams. Confidence is really the runner’s best guide through the training process toward race goals. Workout split times are great, but only inasmuch as they build confidence, which is also influenced by experience, like Liz’s experience of learning that her rival Susan had run a 19:56 5K. Runners are typically taught to believe that the primary objective of training is to stimulate the physiological adaptations that will enable them to achieve their race goals. But what exactly are those adaptations, and what is needed to stimulate them? It does not really matter. What matters is that the unconscious brain knows when the body is capable of achieving the goals of the conscious mind and communicates this knowledge to consciousness in the form of the feeling of confidence.
