Cough, Cough...Again?

I started getting a bit of a cough last night / this morning. I can't believe it...could it just be a relapse of what I had two weeks ago? Something new?

I'm not sure, but I'm going to try and take it easy. I have an 8 mile run scheduled for tomorrow morning, but I'll push it to Sunday if I don't feel up to it tomorrow.

I just hope this will not be an ongoing thing during marathon training....
