This was a tough day to run fast. I'd planned to do a fartlek workout anyway, but Amy and Aaron were in the Cool Springs area and wanted to meet me for lunch. She told me to run fast so I could meet them quickly, which made me take off too fast for the first mile. The first 8 speed bursts felt good, and only the last one was half-hearted. It was HOT today! I had to change out of my cotton work shirt afterward (while waiting for Amy) because it got too sweaty.
