That's a good ride.

If you haven't tried it yet, the rail trail along the Sprinter line is a good ride as well. I usually ride Country Club lane to El Norte, Borden, then in towards the San Marcos Civic Center along Mission. There's a bunch of restaurants near the Civic Center and it makes for a good pit stop. You can pick up the rail trail near the Civic Center and take it all the way back to the Escondido transit center.

There's not much traffic at all along that route (and none of course on the trail).

Lake Wohlford was an absolute butt kicker. Worst hill I have ever ridden. I got my butt handed to me by about 50 "real" cyclists on the way up including the guy I was riding with.
