I was afraid somebody would ask that! Average speed, which in my defense, includes stops in city traffic at rush hour on the way home, quite a few hills on the back roads, quite a warm day and a wind that was not as bad but still a factor: 11.5 mph AVS which came to 6 hours and 40 minutes of pedaling. Made one 20 minute stop for lunch; one 10 minute stop for a cookie and a lemonade and two or three 5 minute breaks en route. Think I could have used a bit more hydration because on one of the steeper hills I began to get cramps in the right thigh. Actually got off the bike and walked it off for a few minutes and was not bothered thereafter. There were also very enjoyable moments of sailing along at 18 to 20 mph on flat sections, a few rather thrilling descents at up to 30 mph. No flats!
