“You can't rush progress.”

Hilarious and outgoing, Brittany Forgler, is everybody’s best friend ― except her own. Her partying, underemployment and toxic relationships are catching up with her. She receives a startling wake-up call when a visit to the doctor reveals how unhealthy she is. Motivated to lose weight, but too broke for a gym and too proud to ask for help, Brit is at a loss, until her neighbor pushes her to run one sweaty block. Soon, she sets an almost unthinkable goal: the New York City Marathon.
