Here in Richond TX most of the time I spend riding is in the mid to high eigthties on morning rides. Sometimes the low nineties when I finally get myself out of the house. I usually average 13 miles an hour for 15 miles. There's usually a good enough breeze to slow me down. I've been pushing this year to go faster without much results. Anyway the heat makes it harder. I would like to see how I would do when it's in the mid seventies but that's not very often here.
