The NY Times published an interesting article that very much aligns with my thinking.....you gotta be ready to feel the pain and suffer a bit!
A few good quotes:
“Mental tenacity — and the ability to manage and even thrive on and push through pain — is a key segregator between the mortals and immortals in running,”
“I was given a body that could train every single day.” Tom said, “and a mind, a mentality, that believed that if I trained every day — and I could train every day — I’ll beat you.” and he added “The mentality was I will do whatever it takes to win,” he added. “I was totally willing to have the worst pain. I was totally willing to do whatever it takes to win the race.”
