Cruise up PCH to Malibu for a quick break. Lazy and out-of-shape riders can go home from here. The rest of us will continue up Malibu Canyon to Mulholland Highway and enjoy the gentle rollers back to Old Topanga. Up and down Old Topanga, down Topanga back to the coast, and the zip back to MDR. Short and full rides are about 31 and 50 miles, respectively.
