Check-In and Time Limits

Ride Share

The Marin Century has instituted a Ride Share service.  Save some gas money and share the trip with a fellow cyclist.  Ride Shares (car pools) will get priority parking at the Start/Finish until the lot is full.  Click here to find a ride, or share your car.

Time
All riders must check-in, and personally sign-in, prior to starting the ride. You will be given a event number making you eligible for support and food and water at rest stops. Anyone found “crashing” the ride will be disqualified and will be forever banned from entering future Marin Cyclist rides and events.
