For anyone interested, Saturday I'll be riding a SART Century loop to San Pedro. The point is mainly to see the Tall Ship Festival in San Pedro. Stay around for an hour or two then return. So it is kinda more like a double 1/2 century since the plan is to stay a little while.
Original meet place is the eastern parking lot at Yorba Regional Park. Leave time would be approximately 8 am.
Forgot to post average speeds.
Cumulative average speed should be around 16 mph after accounting for lights and turns in Long Beach.
My group of 3 usually averages 17 mph on the way out to the beach and 19 mph on the way back (due to the tail wind).
