I ran another 5 miles on the Jordan River Parkway and had a great run! My right leg and knee felt fine before, during, and after the run. The temperature during my run was 20 - 23 (F), and my three layers were adequate. My pace during the last half-mile was 13:40, slightly faster than on Wednesday. The path had some ice on it, but there were plenty of dry spots that I used to navigate around the ice.
After my run on Wednesday, my right leg and knee were slightly sore, but by today they were fine. I've noticed this pattern before, that I need two rest days for my right leg and knee to recover from a 5-mile run. I didn't notice this for my shorter runs.
