"That’s the funny thing about running. The deceptive thing about it. It may seem mindless, but it’s really largely mental. If the mind’s not strong, the body acts weak, even if it’s not. If the mind says it’s too cold or too rainy or too windy to run, the body will be more than happy to agree. If the mind says it would be better to rest or recover or cut practice, the body will be glad to oblige."
