Up Sepulveda to Moraga and then wind our way through scenic Bel Air, past a few way-to-big monstrosities, then up the steps of Stradella to Mulholland Drive. The short ride returns to the Westside via Sepulveda. The long ride continues on Mulholland over the San Diego Fwy to Encino Hills Drive for a steep descent into the Valley. From Hayvenhurst, continue to wind our way over the (not-so) secret commuter route to Valley Vista, Wells, and Dumetz, to Topanga Canyon. Take a break at the Starbucks, and then climb New Topanga over and down to PCH. The short route is 30 hilly miles. The long route is 48 miles with more hills and 3700 feet of climbing. There are a few steep sections.
