I took yesterday off and decided to let my body rest.  My knee felt much better yesterday afternoon and evening.  I decided to run this morning and take it nice and easy with my length dependant on how my knee was feeling.  For the first 2 miles I could tell that the knee was not "normal" but it did not hurt at all.  At mile 2 I stopped and gave the quads a good stretch.  I started running after that and whamo, the knee felt better.  I think I had some tighness in my quads that was causing some tension on the knee.  I stopped a couple more times and just stretched and the knee felt good for the rest of the run.  I kept my time around 8:45-9 minute miles so I was not pushing at all.  Now I am at work and it feels just fine still.  I am hoping a recovery run and a good stretch of the quads was what my body needed.
