A couple of days ago, I advised against running alone during extremely cold conditions -- especially when it's dark.
This morning, with the thermometer reading minus-12, and facing the fact that none of my running partners appeared at our meeting place, I had to make a decision: Follow my advice or turn around and, despite investing about 15 minutes bundling up and another 10 driving to our meeting location, head home.
I compromised, sort of. I cut a mile off the route, covering 3 miles, all the while reminding myself how I would use my flashlight to flag down a passing vehicle should I take a tumble and be unable to get up.
No life-threatening situations to report.
All in all, it didn't feel any colder at 12 below than it did yesterday -- what was it, 4 below? -- though I did put on heavier clothing today.
What's been the coldest temperature in which you've done any physical exercise?
