Yesterdays Run

I tryed to do a short fast run yesterday. I went 2.13 miles at a 7:49 pace....My time was 16:37. My knee felt good. I rested for about 1 hour then went on a slow jog for another 3 miles. The knee started getting a little tighter, however was still ok. I'm still going to ask the Sports Doctor afew question today. Just to get his opinion. Wish me luck.
