I started training for a February 5K. It doesn't go that well. My speed is not where I want it to be. I have a chest cold, but I still run with it. My experience is that it goes away faster if I run. Indeed, today I already feel better than yesterday.

I run much more in a fast(er) pace than for the marathon training, and in fact more than for previous 5K training cycles. We will see how it works out. I follow Hal Higdon's advanced 5K training plan, which I don't particularly like, but I haven't found anything better.
