Creating a healthy, connected Marin one ride at a time.
Since 1998, the Marin County Bicycle Coalition has worked alongside public and private partners to transform how Marin moves. We advocate for safer streets, expand access to trails, and build a cycling community that welcomes everyone from the daily commuter to the weekend trail rider to the student who gets their first bike through Cory’s Ride. When you ride Marin’s roads, trails, and pathways, you experience MCBC.
