I rode, actually, thought how bad could it be, 4 miles in the morning and 4 miles going home IN THE WORST HEAT!
Everyone in my office made comments about how i was going to ride yesterday, when it was SO hot.
I noticed it was windy right away, with strange breezes pushing at my front tire.
my commute is roughly circular, so no matter what way the wind is blowing, i get a head wind and a tail wind on part of my ride. This time, I felt lucky
the tail wind was on my longish uphill.
To my surprise, i discovered that when it is hot, a tailwind is not always better. It felt like the air was still and muggy while I climbed up that hill.

And the heat radiated off the pavement something fierce. I made it home
none the worse for wear., er, well, a bit sweaty!
