Route: Alpine Dam + Mt. Tam
Distance: 53.7 miles
Take it from San Francisco-based Strava when they say, "in Marin County, the Alpine Dam Loop is second to none." We agree, having been inspired ourselves to do this ride many times after crossing the Golden Gate Bridge. There are no bad views, only bike-friendly coffee shops, charming towns, and gratifying climbs that always test your limits. Bonus: keep an eye out for pro cyclist and local Evelyn Stevens out for a training ride.
