The SFR Adventure Series

Creek crossing

Ever dream of Passo Gavia? Khardung La? Paso Agua Negra? Some of us certainly do. But it's not easy to cut a month out of life to explore mountain roads on the far side of the globe.

The good news is that there is much beauty and wildness right on our doorstep. The Adventure Series organized by the San Francisco Randonneurs visits some of the more spectacular country within a day's ride of San Francisco and strings those sights and smells into epic rides.

We offer a full brevet series of 200-600Km brevets homologated by the Audax Club Parisien and run under the auspices of Randonneurs USA. All of them feature remote roads, a mix of pavement and dirt, and unusually large amounts of climbing.

Per-mile, the Marin Mountains 200K is probably the hardest course. It is difficult to finish within the time limit, since RUSA and ACP timing rules assume paved rides and make no provision for rugged terrain. King Ridge and Orr Springs, however, are much tougher overall. Their length, remoteness, and scenic beauty make them experiences you will not soon forget!

These brevets occur after other full brevet series in the area, and they are scheduled from longest to shortest distance to take full advantage of long summer days. The dates for 2016 are as follows:

This year, Old Cazadero and Marin Mountains are delayed by a month relative to their traditional dates in order to accommodate Paris-Brest-Paris in August. For registration, waivers, and fees, please see

All four routes are also available as RUSA permanents.

These courses were designed by Max Poletto with help from many others. Thanks to David Strong for inspiration and course suggestions, Rob Hawks and Kara O'Keefe for encouragement and support, and Chip Coldwell, Russ Fairles, Jesse Gibbs, Brian Koss, Vidas Placiakis, and David Strong for exploring several ride segments with me.
