I did a slightly longer version of my Three Peninsular Ride today:
01:52:53 ... hh:mm:ss
42.48 ... k
22.50 ... kph (average speed)
55.70 ... kph (maximum speed)
A very nice ride. I went a little too fast coming down the AB bridge toward Atlantic Beach. I struck a small pebble during that decent and heard a loud crack as I rode over it and looked down to see I was traveling over 50 kph and thought, "What if I had a blowout at this speed? And here I am on a damn bridge with cars and trucks passing me!"
