This is a ride we did back in March and should be good for the Labor Day weekend. It keeps us off much of PCH and Ventura Bl. and doesn’t have too much hard climbing.
Out PCH and up Topanga to the post office. Instead of taking Old Topanga, we’ll stay on new Topanga to the top and down to Mulholland. Careful making the left turn here and connect over to Valley Circle Bl. Continue up to Burbank, and then east to De Soto. South past Ventura Bl. where De Soto turns into Serrania and then Wells. Follow Wells to Valley Vista and Rancho and finally a short stretch on Ventura Bl. Stop for snacks at the Corner Bakery on Haskell, and then back over Sepulveda to the Westside.
Total route is 55 miles with 2800 feet of climbing. Not too much! Here is the RideWithGPS for the route: https://ridewithgps.com/routes/29526627
People who want a shorter route can turn around somewhere on Topanga. It may be warm in the valley!
