Notes
I ran this an hour earlier than normal, and with no coffee beforehand. The sun really compounds the heat issues for me on these longer runs, so I thought I'd try doing one mostly before the sun came up. It was a bit scary at the park at 4:30 under a full moon.
I started off slower than normal, but my HR still stayed very very low. I averaged UNDER 130 for the first 5, which is just weird. I saw a cop parked at the entrance to the park at the end of my first lap. He was probably sleeping. If it were midnight, I might not suspect so, but 5:00 AM? What's he protecting the park from?
Overall, the experience of getting the run pretty much done before the sun is up was a positive one. I'm still not sure how much I'll do it, because it's hard to wake up. I'm also sort of wondering if not having coffee was responsible for my HR being low.
