Meet Glennis: A professional runner who has been running for more than 20 years and trains at the Olympic level. And Danica, a writer and marathoner who is working to get back in shape after having a baby. Together, they coach more then 75 students. Watch how they inspire each other, because, "Behind every strong woman is a tribe of other strong women who have her back."
