We do a night ride with lights on Monday, Wednesday and Thursdays. We leave
Colonel Bill Barber Marine Corps Memorial Park at the corner of Barranca Parkway and Harvard in Irvine and ride down to the back bay, do some loops and back to the park ending up with about 25 miles. We stay on the bike trail the whole way. If you're interested let me know. We average about 18 or 19 mph for the whole ride.
