I did it! I finally remembered to take carrots to the two horses that I visit during my run. I usually pick a handful of grass, but the ground is covered with snow and I took carrots today.
Nice running day and nice 4.8 mile run. My wakeup HR was 52. It went up because two nights ago I only got 4-5 hours sleep due to waking up with a stomach ache. I usually don't get stomach aches, and I think it was something I ate.
