We love this quote because it's so applicable to running and it's a manta we repeat many times to ourselves. We are capable of a lot more than our mind tells us or convinces us is possible. Next time you are out for a run and your mind tells you to stop, push through and give a little more. If it's your body telling you to stop, i.e., a bad/nervy pain somewhere, stop. However, most of us don't push through the discomfort because we convince ourselves that it doesn't matter. You are capable of a lot more than you think and the greatest highs can come from pushing through discomfort. Give a little more on your next run or workout.
