Long(ish) runs

We ran 6 miles on Saturday which is the longest run so far, and my personal long distance record.  I felt pretty good for the first 5 miles, but felt a sharp pain in the shin/knee area.  I walked for about 20 seconds to get a better sense of the pain and whether I would be able to complete the last mile.  I felt good enough to finish the run but the tendon (my guess) on the outside of the knee was (and has been) bothering me for the rest of the weekend. 

We ran 5 miles today and I was extremely nervous that my tendon pain was going to keep me from the run.  But I felt great throughout the entire run and am very encouraged by the lack of pain and the strength I felt during the run.  We are due to run 4 miles tomorrow which, in my brief history of running, the second consecutive day of running has resulted in a bad run.  It was pretty darn cold this morning, with the thermometer showing 45 degrees.  I'm hoping for a bit warmer tomorrow, but once my muscles got warmed up I found the cool air very refreshing so maybe I should be careful for what I wish for.
