Girls on the Run-Chicago is a non-profit after school program for 3rd through 8th grade girls. We use running to help prepare girls for a lifetime of self respect and healthy living. The character-building program focuses on building self-esteem, confidence and improving physical and emotional health. Over the course of a 12-week season our volunteer coaches teach life-skills lesson such as handling bullies, dealing with body image and the media, making healthy decisions and contributing to the community. Along the way, the girls train together to run in a 5k (3.1 mile) run, the WonderGirl 5k.

The WonderGirl race series, with more than 70 events across the United States and Canada, is the second largest 5k race series in the nation.
