The headwind felt like hot air coming out of a space heater. My water was hot by the time I got to work. I started sweating by the time I got to the end of my driveway (not very far). Needless to say, it was hot; probably 115 F in the sun over the asphalt since the heat index was supposedly 100 F in the shade.
I took my sweet time, averaging 8.67 mph.
