I went on a brief 4  miler yesterday after about a week off.  I went home on a short vacation, and my sinuses were giving me grief.  I didn't want to push it and suffer through my time home, so I didn't run while I was there.  

My back is tight today, but I've really got to get back on the running schedule.

I REALLY need to pick out a race for the fall.  Maybe a trail half marathon would be a good thing to shoot for.
