Post-Donation

I gave blood on Sunday and haven't really noticed any effects until this afternoon. In fact, it felt the past few days like I hadn't donated at all. I was ready for a run today, but I quickly noticed a little fatigue and slowness. I'd planned on doing some speedwork for the first time in a while, and that's what I did. I threw in some fartleks during the course of my 6-miler, speeding up for 4-5 street light poles each time. I didn't run terribly fast, but enough to get down to an 8-minute pace for a few seconds. I also got chicked - twice by the same woman - who totally blew by me when I was shuffling along at 10 minutes/mile. That's okay. I bet she didn't give blood a couple of days ago.
