I am an old fat guy. I ride quite a bit but I eat and drink beer. Life is good. But today the ride in was almost 80 degrees and very humid. I made sure I drank both my water bottles and one extra one from the px and one on the ride home. Actually 14 miles at 94 degrees wasnt too bad at all. I did not set any speed records but I actually felt like I could turn around and ride back. The only problem was I wear glasses so I cant wipe my forhead with my glove when I stop at stop lights, and I was sweating so much the sweat would get in my eyes and burn big time. I avoided hot days last year, but I am riding again tomorw even if it is 94. Gotta draw the line somewhere. feel great.
