I had the same experience as Elk. I always thought it was good to exercise with a cold, and I was told to do it at 75% of my normal workout. But I got a regular old cold one year and was not about to let it stop my workouts. Needless to say I ended up with a cold for about a month, I felt awful until I stopped to let my body recover. That might just be how my body works, though. So I recommend going for a ride while you have the weather but taking it easy to see how you feel.

I hope you feel better soon.
