Catching up after the flu

Had not run since Thursday due to the flu beating me up over the weekend, I was back to the running thing today. I ran after going to the supermarket today after work around 6:45 p.m. I started my run to the conservatory and did 5 laps there, did several battles with a few guys, I think I won but when I was finishing the run I had one guy kicking my heels, and I was huffing and puffing, laps progressed from 6:30,6:10,5:47,5:19,5:04. I am in very bad shape but that can be improved. Glad that I ran today, good things happened there and before the run I was thinking on bagging the run, you never regret a run. Did around 6.3k in 36:51.
