Well, I didn’t cough up a lung…
… but I did cough up something phlegmalicious.
Lessons learned: my time for a mile was about the same as it was when I was but one score old. This means that my base fitness level hasn’t gone down (a good thing) but it hasn’t improved (a bad thing). The remedy is obvious: do it again tomorrow. I’ll have to work out a schedule for the regular work week though. My work hours give a preference to evening workouts. I’m not sure if this will be more or less difficult than working out in the morning.
Also, I was not able to run the whole thing, but had to walk a bit in the middle, perhaps fifty yards. Aside from that, I kept moving at all times.
It felt good, surprisingly, except for the phlegm.
Next steps: Repeat. Extend. Endure.
