Where to ride in San Diego?

I’m going to be in San Diego for work this week and I am wondering where I should ride. I’ll be staying at the Westin Horton Plaza (near downtown, I think). Need to get in 55 miles. Does anyone know any good resources to find routes (preferably with maps)? Anyone interested in riding on Friday morning?

jump on the 101 from Pacific Hwy, go north as far as you like
