THE OBR: OLEMA - BOLINAS RIDGE
Total Elevation: 6,669 feet
Escape reality and enjoy the entirety of the Bolinas Ridge on the Olema-Bolinas Ridge Gravel Ride, or The OBR Gravel Ride. Ascending Mt. Tam on Railroad Grade is just the start of this hefty mixed terrain ride. From East Peak, enjoy a mixture of pavement and gravel descending back down to the intersection of Ridgecrest and Bo-Fax.
