Back when I was employed and on occasion commuting by bike out of Brooklyn, I learned that a temp over 85 was too hot and riding in that would really do me in for a few days. I’m a bit of a wimp I guess and I read of folks riding in the 90’s, but for me, no thanks. I got up today to ride at. 7, it was already 84 and headed to over 90 so I opted to not ride, went and did a pool workout instead.
