Check So Cal Cycling.com, under training rides. There are a few. BArry Wolfe ride Tues and Thur morning. Love Ride and the Amigos ride on Sunday out of Griffith Park. Depending on what time in MArch the Rose Bowl Ride will start Tues and Thursday Nights. There are 100 rides that leave Santa Monica on Saturday. Monday Night is Wolfpack which is super fast night ride that leaves down from Echo Park. Cyclones is another night ride on Mondays thats a little slower and shorter than Wolfpack. Hope this helps
