Brittany Runs a Marathon is a true story about a 20 something year old woman who goes to the doctor to get some adderall. When the doctor sees her, he suggests she lose weight. As time passes she decides to run to lose weight. The movie is an OK movie. It tells a good story that has to do a lot with friendships and hardships. If you’re enjoying what I’m explaining the movie is about, go see it. I give it two and a half stars.
