Thanks to Rick for an awesome suggestion!
Meet in the parking lot (the part that faces Reservation Road, next to Jack in the Box). Address is 211 Reservation Road, Marina, CA.
Ride the Monterey Peninsula Recreational Trail and Ocean View Blvd/Sunset Dr to either Pt. Piños (~28 miles round trip) or Spanish Bay (~30 miles round trip). Stop for lunch somewhere near Fisherman's Wharf or Cannery Row on the way back.

Note that ridewithgps elevation calculations always result in more climbing than actual. This is pretty much a flat ride.
This is sure to be a fun ride with ocean views galore!
