I already knew from last year that running a single mile is an odd feeling at first, and that when you compare it with the misery you felt during the middle school mile run, it puts your fitness gains into amazing perspective.
The stretch of subzero wind chills and its corresponding single-mile-run streak have taught me a few more things about the experience:
1. Basically, my head will never not sweat if I'm moving faster than a brisk walk for more than a few steps.
2. My nose will still run, but I can make it back without a Kleenex break.
3. I still need to stretch afterwards. I'd gotten lazy about it, thanks to some poor time management, and after a few days of that, I woke up with my first charley horse in years.
I haven't skipped stretching since, and the charley horses haven't recurred. Correlation doesn't mean causation, but right now, I think my theory is a good one.
4. Though I happily miss out on the runger, I still catch a brief runner's high. That also might just be relief that the Holiday Run Streak lives another day, but hey, whatever lifts the spirits!
