I got out for a noontime run today (OK..more like 12:30pm).
I went to the eye doctor this morning and my eyes were still a bit dilated. I was wearing sunglasses in front of my computer screen, so being outside in the bright sun was a little annoying - but I didn't want to go to the gym an run on the treadmill with sunglasses on (what a sight that would be!!!!)
This was my first official run since giving blood on Monday (I did a run/walk with my son yesterday morning...I'm not sure if that "counts" or not). The first half mile was rough. My legs were stiff and heavy; I was contemplating whether I should stop, turn around and try to run tomorrow morning instead. I somehow convinced myself that it would get better - and luckily it did.
As expected my HR was higher - but not by 15-20 bpm like I thought it may be. Average HR was 156 with an average pace of 10:55/mile. Last week I ran the same lake loop in a slightly faster time - 10:45/mile pace - and an average HR of just a tad lower - 154. Perhaps it won't take me a full three weeks to recover from the blood donation this time???
