Counselor, lecturer, sort-of-single mom, and runner Courtney Edwards visits the Pain Cave to address the mental side of the sport...but maybe not in the way you've heard it before.  We cover a lot of ground: the emotional benefits of running and exercise, the biochemical basis behind these emotions, addictive behaviors, eating disorders, the impact of running on psychology, mindfulness and gratitude, how to tackle periods of low motivation, and the pros and cons of goal setting.
