Uninterrupted bike path/lane in the Valley?
I'm new to So Cal, and I'm looking for a training path (road) without stop signs/lights in the Valley. The other day I did a nice 13 mile loop - Woodman - Riverside - Laurel Canyon - Roscoe back to Woodman. Nice bike lanes but I had to stop 23 times on the route for stoplights.
Is there any place in the Valley where there's even a 3 or 4 mile loop with no interruptions?
Nope. In time you will learn the timing of the valley traffic lights. There is a system and it's one of the best in So Cal. On a 30 mile ride just in the valley I maybe need to even slow down 6 times.

Over on the east side....
The La river bike path is a few miles you can loop on that...also in GP and Forest lawn....minimal stops...between those you can get some non stop riding in....and as a bonus..if you want you can do some good climbing up Trash Truck Hill them Mt Hollywood drive...
Mullholland between Cahuenga and Sepulveda. 10 miles or so only 3-4 stops. City streets however no shoulder lots of climbing. Experinced (crazy) riders only.
Try the area along Valley Circle.
I did a run there about a month back. There is a small bike line starting in the north, and it can be a bit dangerous. But, it'll take you from the north valley (118) to the south valley (101) and rides parallel to Topanga Canyon. Once you get out of the first parts, Valley Circle opens up and rides next to homes. There bike lane opens up, and there are a few hills you can go down. I didn't get stopped too often, and had a good time.
If you're a little more advanced, you can even try Box Canyon which is in the same area. I've only driven it when I was younger, and from what I can remember, it's pretty hilly.

Great advice, thanks! I did do a little trek from Van Nuys out to the Hollywood sign via Laurel Canyon and Mulholland Dr. Wow, talk about lots of hills. Griffith Park looks senic. I'll have to do that one next.
