From an Olympic medalist runner and the record-holder in the women's marathon and half-marathon, a vividly inspirational memoir on using positive psychology and brain science to achieve unparalleled athletic success The day Deena Kastor became a truly elite runner was the day she realized that she had to ignore her talent--it had taken her so far, but only conquering the mental piece could unlock higher levels of achievement. In Let Your Mind Run, the vaunted Olympic medalist and marathon and half-marathon record holder, will reveal how she incorporated the benefits of positive psychology into her already-dedicated running practice, setting her on a course to conquer women's distance running. Blending both narrative running insights and deep-dive brain science, this book will appeal to and motivate steadfast athletes, determined runners, and tough-as-nails coaches, and beyond. This memoir, written by perhaps the most famous American woman active in the competitive world of distance running, will appeal to the pragmatic athletic population, and jointly to fans of engaging sports narratives, inspirational memoirs, and uplifiting biographies.
