You said "perfect weather" on a July 4 ride. what does that mean?
I'm 76 now. I used to be a prolific sweater but now I hardly perspire at all. Hot weather utterly wipes me out. An easy 40 mile ride for me in temperatures above 80 degrees would require an REM dream cycle 2 hour nap afterward. That's how I know I've gotten old.
