A slower but nice rest run

I ran an hour along the Jordan River Parkway and enjoyed myself. My wakeup HR was 54 due to not enough sleep Sunday night (a phone call woke me up and I couldn't go back to sleep. The call was a wrong number), and I could tell I was tired. So, I made it a "real" rest run. The temperature was in the mid 30s (F) during the run, and the sky was cloudy with a 5-10 mph headwind going out.
