4 miles easy

Ran 4 miles easy at Silver Lake this morning. Weather was nice and cool so no excuses there. First 2 miles were smooth at 19:51 (9:54 and 9:55). Started getting occasional sharp pains in right knee and right ankle during 3rd mile so I concentrated on getting a good foot plant. This slowed me down a bit, and I finished the 2nd half in 20:15 (10:08 and 10:07). Total time was 40:06 (10:02 ppm).
