I claimed that I would not run in temperatures of 20 degrees or lower. What I meant was temperatures in the 20s or lower.
Thanks to tfh for pointing out my error, else you might have checked the weather near me, which as of this posting was 24 degrees, and thought, "Whelp, I guess ol' Viper's gonna go run tonight."
What I should have said was "29 degrees or lower" or more simply "below 30 degrees." And while I'm at it, I might as well amend my protest further and say that if the predicted high temperature is below freezing -- that's 32 degrees, for you nincompoops -- I'm not running.
So, in short. I will not be running tonight. I might run tomorrow. Only Goddard knows.
