Not too bad, heat & humidity-wise. This weekend is supposed to be abhorrent, by Vermont standards. 90Fs...
I rode behind a 20-something guy with a messenger bag on a red hybrid. Then a guy on an MTB came out onto the MUP and we had the world's slowest peloton.

Nah, it wasn't that bad. 15 or 16MPH into a headwind. Relaxed.
Saw quite a few other riders out today. Nice to see.
