Below is the route sheet, and a video, from a really excellent 42 mile loop we rode on November 21, 2008 out in south-eastern San Diego County. The 13 miles of dirt road on this loop is rideable on a road bike with 28mm tyres, IMHO, but we rode, and recommend, tyres wider than that for this route.
This was my second Rough Riding adventure on my 1984 Holdsworth Special, a British sport-tourer which was my first ever sponsored bike. Originally, back in 1984, I set it up with all Campy Super Record and tubular wheels. This was my first pro-level racing bike and I rode it during my San Francisco to Los Angeles world record on April 17-18, 1984, when I was 17. A year later I became sponsored by American custom frame builder Ron Stout and so the Holdsworth became my back-up bike. After racing RAAM in 1987 I pretty much quit riding the Holdsworth. I think it's been sitting around for literally 20 years with no parts on it. Recently I put it together as a Rough Stuff bike with most of the parts, and wheels, from my Bridgestone RB-1. Thus it's mostly Suntour parts with Phil Wood hubs and bottom bracket, and 700x by 32mm Vittoria Cross XN Pro tyres and 38/28 low gear. This bike is an absolute dream for Rough Riding! (I'll do a full post just about this bike at a later date.)
Whatever bike you ride, this is simply a really nice ride to do. The dirt road section through Boulder Creek is superb, with wide, dramatic vistas, absolutely epic, long climbs, vast quantities of silence, and a true back-country feel. As with some of the other rides we've reported about here, if you pay attention, you'll spot some other dirt roads in the area; we plan to go back and investigate those, too. (Many are noted on the route sheet below.)
Here is the route sheet. Bring a San Diego County map for reference. Plan on about 4.5 to 5.5 hours, total time. Be sure to bring plenty of water and food as you will find no supplies, and essentially no people, on this route until you get to Lake Cuyamaca!

Below: Here's a Quicktime video slideshow of the whole ride, but don't waste your time on this little, itty-bitty version! Instead, click here for the full-size Quicktime slideshow with large images which we have hosted on our website. There are 76 images, plus a soundtrack (turn up speakers), so it should be pretty fun and interesting. Let us know what you think by posting a comment below! Thanks for your support and interest!
