I could tell during my situps that my body was tired. However, my wakeup HR was 51, and that was a good sign. I left home realizing that I might abort the run due to being tired. I ran at a slower pace than I did on Monday and made it through the 10.2 miles without walking. It took me about 16 minutes longer than on Monday. The temperature was in the mid 40s F, but there was a 10-15 mph headwind on the way out. I was looking forward to a tailwind on the way back, but the wind had mostly died down by the time I turned around.
