Running or racing when you are sick

I am not a Doctor, but I know my own body well enough to determine the difference between being very sick and just having a cold. I have had a nagging cold for close to 10 days now, but I actually feel better when I workout and I had a decent 5K race last weekend (18:57) finishing in the top 10. Let me get to the point of my post, which is that YOU CAN workout and even race if you just have a head cold. I used to shy away from training when I even felt the slightest symptoms of a cold coming on, but now, I try to train right through as long as I am not getting any worse. By no means do I suggest that anyone workout or race with a fever, a severe chest cold, bronchitis or pneumonia, but a mild head cold is no big deal and if you are like me, you might find out that you actually feel better after some good hard exercise!!!
