15 minutes on the treadmill, barefoot; second day in a row. Remembered to bring a little water to stave off the thirst. That was smart. So was turning on the music.
But when I asked myself Why are you doing this? and the answer was (in part) To get better sleep, I felt a touch of irony.
Treadmill says I burned 177 calories.
1.01 miles; pace was 4.04 mi/hr.
