Here is a preview slideshow of the Saturday route for the 2010 Rough Riders Rally. The route is approximately 45 miles with approximately 5000' of elevation gain and features single track, double track, fire road, gravel road, abandoned paved road, and newly paved road. Some consider this "mountain bike territory," but this route is 99% rideable by an accomplished Rough Rider on a road bike with 32mm cyclocross tyres (or on a cyclocross bike), and perhaps 90-95% rideable on a road bike with 28mm road tyres.
Special thanks to my long-time friend and local guide, Ed Levinson, a Furnace Creek 508 veteran who owned and operated a bike shop here for over ten years. (Our host shop for the Rally will be Mt. Tam Bikes at 357 Miller Avenue, as pictured in the slideshow.)
This region is truly superb cycling, with fantastic views of the San Francisco Bay, Alcatraz, the Marin Headlands, Mt. Tamalpais ("Mt. Tam"), Tiburon, Mill Valley, the Bay Bridge, a bit of the Golden Gate Bridge, and dramatic, rugged Northern California coastline. Honestly, this is cycling paradise, a region unparalleled for its beauty, diversity of scenery and riding surfaces, and its cycling-friendly trail signage and local population!
