Book excerpt: Girls (and boys!) can become stronger and more resilient simply by realizing how strong and resilient they already are, and running provides a pathway to that realization. Programs like Girls on the Run (which serves more than 200,000 girls each year, through 200 councils, across all 50 states) help kids discover their inner reservoirs of fortitude. Such programs address the whole child when she most needs a counterbalance to harmful stereotypes of who she should be and how she should act. In the words of participants, “Girls on the Run made me realize that I am the boss of my brain.” “At Girls on the Run I learned how to be comfortable in my own skin!” Refusing to quit, overcoming weariness, skinned knees, and self-doubt to finish a cross-country run, the resolute narrator of I Am Darn Tough realizes that she is stronger than she thought, inside and out. I Am Darn Tough shapes the Girls on the Run philosophy into a beautifully illustrated narrative to inspire any child, anytime, who wants to run toward greater confidence in themselves.
