Yesterday I rode the beginning of the Shift 1 Route, starting at HWY 395 and Old Castle Road (only 2 miles from my house, as it turns out), and continuing along until I hit HWY 76. There, the route turns right and heads up past Mt. Palomar. I didn't want to spend that much time alone on 76 though, so I just headed back for home. Here's the profile of the first 20 miles or so.
