The plan was to go about 4, but to take it easy and see how the knee felt. I also got a new pair of shoes to see if that would help. I got about a mile, and the knee started hurting a little. By the time I reached 1.5, I was done and turned around. It is very frustrating because after a day of rest it feels fine. I can go up and down stairs and walk on it with no problem. It just hurts when I run on it. Total time was 21:58 (7:19/mile).
