Flu recovery run #1

I didn't have high expectations when I set out on this 4 mile run. So it went better than expected. My effort level was consistent with a recovery run and I felt OK. But I did have some aches in places when I started. I was worn out when I finished and I can feel it in my lungs, that kind of burning, aching feeling you get from wind sprints.  But I held back even though I felt good and I didn't bonk.
