“How do you survive those less-than-perfect situations when discipline isn’t enough? When grittiness gets you through the workouts but can’t seem to get you through the rest of the day? As a runner, you’re highly in tune with your body, and you know its highs and lows; you know your normal aches and pains, and you know when you should probably see the athletic trainer. Learning the highs and lows of your mind is much harder.”
