When are you coming down? Team SCCX tries to get together at least once a week, usually on the weekend. As for trails, there is Topanga Canyon State park over in Malibu area, lots of trails off of Angeles Crest (hwy 20 in La Canada/ Flintridge area, and the Arroyo Seco area in Pasadena, off the 210 fwy. Anything in the San gabriel mountains is pretty good too. My favorite is an area in Arroyo Seco behind JPL (Nasa Jet Propulsion Laboratory) in Pasadena, you have a combination of a flat trail with 5 or 6 water crosssings, long gradual climb for 6-7 miles, half way up the climb you can choose to either keep climbing, come back down the way you went up or take the technical singletrack back down, on this trail you have to deal with a few watercrossings, boulders, tree roots, low overhangs and the singletrack being right on the edge of the trail.
