Brittany Runs a Marathon

B +

The title of this film, “Brittany Runs a Marathon,” is not really a spoiler. Yes, it is an inspiring story of a young woman named Brittany (Jillian Bell, outstanding in her first lead role) who has a sobering visit with a doctor, an equally sobering visit with an expensive gym. She decides that since running is free, she will start with just one block and see — literally — where that takes her. But the real story of the film is about what she discovers along the way about herself and the people around her. Her real problem was not being overweight. Her real problem was what being overweight helped her hide from.

Brittany feels that she is both stuck and drifting. As she approaches 30, her friends all seem to be settling into jobs and relationships while she is still living in college slacker mode, sharing an apartment with her BFF Gretchen (Alice Lee), and barely managing her internship-level job with a small theater group. Brittany is in debt, goes out partying nearly every night, goofs off at work, and makes fun of a neighbor they call “Moneybags Martha,” scrolls through social media to look at everyone else’s seemingly perfect lives, and tries very hard not to notice how awful she feels.

Brittany goes to a doctor because she says she cannot focus and asks him for Adderall. He tells her, as sympathetically as he can, that what she has to do is lose 50 pounds. She cannot afford a gym. The longest journey begins with a single step. And so, she begins with a run for just one block.
