Girls on the Run is a non-profit program that uses running to teach girls life skills and encourage physical activity. Through twice weekly lessons taught by certified coaches, the program curriculum draws from Lerner's Five C's of youth development model to improve girls' competence, confidence, caring, character, and connection. An evaluation of the Spring 2015 Greenville County Girls on the Run program found statistically significant increases in participants' self-efficacy towards physical activity and time spent being physically active based on pre- and post-season surveys. While other measures like confidence and connection also increased, the changes were not statistically significant.
