Nicole, when I had Pneumonia a couple of years ago (November/December 2006), I had to take 3 weeks off... then the day I could start back, I got a stomach virus... so another 3 days off... so basically a month off - from any Aerobic activity.<br><br>
When I started back, after a few days to work out the 'kinks' - I felt good running. It comes back so quickly. You'll be fine. Just do what you can, and what feels comfortable. Swimming, and cycling will help though. I couldn't even do that stuff during my break, all I did was some pushups, and core work, to keep from feeling like a slob. My doctor laughed at me... because I kept asking when I could start back to running. He supports my decision to run, and totally works with me (he runs the occaisional 10k himself, and has run a marathon or two), but I think he thinks I'm nuts <img alt="biggrin.gif" src="http://files.kickrunners.com/smilies/biggrin.gif">
