When you’re on that course and want to give up, think about all the times you kept going. Not just in running, but all those times you were strong in life. When you hugged your crying friend, when you grabbed your mom’s shaking hand, when you decided to keep living. Let those moments of pure strength rush through your blood until you realize you are indeed strong enough to beat this course. Because you are strong, no matter what anyone thinks.
