Brittany Runs a Marathon

“You can't rush progress.”

Brittany Forgler (Jillian Bell) is everybody's best friend, the loud one at every party, and she wants a way out of the life that is catching up with her after a doctor's visit goes badly. She has no money for a gym and too much pride to ask anyone for help, so she starts with a single block. Paul Downs Colaizzo gives her Catherine (Michaela Watkins), the neighbor who nudges her along, and the two women stay close even as the miles pile up.
