I ran my 5-mile route on the Jordan River Parkway. It was a heavy run because I was maintaining a faster pace. During the first half-mile, my pace was about 12:15. During the next mile, it was around 11. For the rest of the run, my pace was 10:30-11:00 with a few distances faster than 11:30 and a few around 11:10. I was out at 8 am, and the shade temperature was in the mid 60s. There were quite a few people on the path.
My wakeup HR was 50.
