The itinerary is 20+ miles. Pedal across the Golden Gate and loop through the Marin Headlands and into Tennessee Valley. Expect a 60/40 mix of dirt to pavement, a fair amount of climbing, 360-degree views and good company! Plus after-ride beer and food! As always, Sports Basement guides will be on hand with plenty of snacks, electrolytes and spare tubes, as well as direction and stoke. No one gets dropped!
