A few years ago as I was developing curriculum for a pre-teen girls therapy group I was creating, I came across Girls on the Run. GOTR is a program for 8-13 year old girls that focuses on healthy body-image, confidence, and self-esteem. In addition to learning and discussing these topics at each meeting (2x/week), they also run and learn about ways to stay healthy. At the end of the semester long program, the girls participate in a 5k. What an amazing program! I can’t say enough good things about it.
