Ride a 29 mile sight-seeing loop from Founders Plaza in Balboa Park (north side of El Prado between 6th Ave and Balboa Dr) along the bay to Pt Loma, up Canon St to Catalina Blvd to Cabrillo Monument. Return via Sunset Cliffs, Ocean Beach Bike Path and Mission Hills.
I can bring 3 other cyclists into Cabrillo Park for free. Extra riders will need to either have own pass or pay $3 entry fee (good for 7 days multiple re-entry).
This will be a leisurely paced sight-seeing no-drop ride. Multi-geared mountain & road bikes welcomed. Please bring spare inner tube, pump or CO2 canister, water bottle, snack for yourself, $5 cash (in case of mechanical failure then you'll also have enough to catch a bus home).
And, in case you haven't done much group-riding before:
