I wish I could think up stuff like that.
I think some people are just physically better able to tolerate heat than others. To say I sweat excessively is an understatement. I always have. I don't know anyone who sweats more than I do. I can literally soak a tee shirt and most of my shorts with just mild exertion on a hot day.
I rode 53 miles today. The thermometer at the bank said 100 degrees on my way home. I wore trunks, a long sleeved wicking tee shirt, and a wide brimmed hat to protect me from the sun. I drank about a gallon of water and a quart of Gatorade. As I was riding I kind of felt like my pedaling was turning a big fan that blew air on me and kept me cool. I felt good as long as I was moving. There were a few other folks out on the trail too, but not many.
I figured it was too hot to do anything else so I might as well go out for a ride.
