This is so true for me! It became especially true during my 17 mile trail run last weekend. While my legs were aching and telling me to quit, my mind was saying stuff like, "You can do this!", "Push it!", and "Think of how happy you will be at the end". My mind is really the best weapon against negative thoughts and sore ankles. They weren't lying when they said 10% Physical, 90% Mental.
I also love the person who said this: Chrissie Wellington. She's a British triathlete and four time Ironman Triathlon World Champ. And she's one of three women to hold 3 consecutive victories at the Ironman World Championships. If it's one thing I admire, it's a strong woman. She is definitely an athlete I look up to.
Has your mind ever helped you out during a long run or a race?
