My wakeup HR was 49, and I felt pretty good. I was on the Jordan River Parkway by 8 am, just as the sun peaked over the Wasatch mountains. While I was running, I saw several young runners with numbers standing near several adults. I stopped to ask what race was being held. It was a 5K fund raiser. The kids looked like Jr. High age.
When I left home, the temperature was 34 (F), but it warmed up as soon as the sun came up, and after I'd run a mile I was plenty warm. My pace for the run was between 11:30 and 12:00, with most of the miles about 11:45. It was nice to be out.
