This 400k/600k covers a huge diversity of territory from beach views along the PCH, to 50 miles of grade isolated bike paths, to views of the highest peaks in Southern California (San Jacinto and San Gorgonio), huge wind turbines, vast desert landscapes, vista of lakes and high plains, and back to Pacific ocean.  The 400k has only 6000 feet of climbing, mostly in a slow gradual climb toward Beaumont.  The 600k adds one huge climb up Montezuma, right after the overnight, but otherwise the additional climbing is spread out and relatively short.  It’s scheduled early in the year to avoid the possible high temperatures in Palm Springs desert area.  The weather at this time of year is generally exceptionally pleasant, except (600k only) for normally cold temperature at the top of Montezuma in the early morning hours.

The route  makes a giant  loop from Foothill Ranch to Laguna Beach and the PCH, Santa Ana River Trail (SART), Corona, Norco, Upper SART, San Bernardino / Redlands, Beaumont Banning, through the pass of San Jacinto and San Gorgonio, around Palm Springs and Palm Desert, a stretch along the Salton Sea, then back East to Borrego Springs for the overnight stop at Desert Sands Vintage Trailer Park.  We will have a nice spread of food, place to shower, and even a few hours sleep if you desire.  The 400k ends at the 600k overnight control and a shuttle will be provided back to the start in the morning. The 600k continues climbing 4000 feet up the Montezuma Borrego Hwy (the glass elevator), then downhill to Lake Henshaw, past Mt Palomar, onto Valley Center, and then onto Oceanside.  From there, north along the Pacific coast to San Clemente, Dana Point and then inland back to Foothill Ranch.  The first day has little climbing and mostly gradual grades.  The second day (600k only) has the monster Montezuma climb, and a few other bumps, but nothing big.  Overall it covers a vast area of Southern California with great views and minimal urban slowdowns.

Please signup at least 5 days prior, so shuttle service seating space (400k only) and other logistics can be properly handled.  For both 400k and 600k riders will have drop bag service to the overnight control, even large pads and sleeping bags are fine too.  Actual bed space is limited to first come first serve, but we have had plenty of floor space in the past for everyone.  If you want a private room for peace and quiet, reserve early in Borrego Springs as all the motels fill up well ahead of time.
