Melodramatic, but the truth…
A runner who could not run was out of his element. He would not even think of himself as an athlete; ridiculously there would be a kind of guilt about it; that was the worst part. He would begin to feel uncomfortable around his training comrades and the feeling would be mutual, like a newly wounded soldier among the embarrassed whole ones, who would not wish to be reminded of certain crap game aspects of life.
Once A Runner, John L. Parker, Jr.
Great book about a miler breaking four minutes
