Growing up in Santa Monica, California, Julie Weiss would do almost anything for love. She drank, she quit school, she stole - and she ended up a mother in her teens. Years later, overweight and depressed, she put one foot in front of another and found a new road beckoning. In 2012-13, Julie - aka the Marathon Goddess - ran 52 marathons in 52 weeks.

Deena Kastor was a star youth runner with tremendous promise, yet her career almost ended after college, when her competitive method - run as hard as possible, for fear of losing - fostered a frustration and negativity and brought her to the brink of burnout. On the verge of quitting, she took a chance and moved to the high altitudes of Alamosa, Colorado, where legendary coach Joe Vigil had started the first professional distance-running team. There she encountered the idea that would transform her running career: the notion that changing her thinking - shaping her mind to be more encouraging, kind, and resilient - could make her faster than she’d ever imagined possible.
