Normally I run a two-hour medium run, but today I felt tired and reduced the run to one hour. My wakeup HR was 49, and I felt pretty good throughout the morning and early afternoon, but as soon as I started running (about 3 pm) I could tell I was tired. There was a headwind (5 mph) going out.
I picked up litter during the run, and enjoyed being out, even though I wasn't full of energy. The temperature was in the mid to high 40s (F). I wore long pants, which was a mistake, and I got quite warm during the run (taking off my windbreaker helped).
