Some think guts is sprinting at the end of a race. But guts is what got you there to begin with. Guts start back in the hills with 6 miles to go and you're thinking of how you can get out of this race without anyone noticing. Guts begin when you still have forty minutes of torture left and you're already hurting more than you ever remember.
