Wow, second degree, that musta hurt like a fothermucker. How long before the burning sensation dissipated? I'm not sure if there's a difference between first degree frostbite and frostnip, but in my case last year, I was in serious pain the first two hours afterwards, but still had to take a painkiller later in order to get to sleep. This year, I've gotten better about recognizing the signs, and the longest I've felt serious pain has been an hour or so. Strangely, last Saturday's mild frostnip kinda had a delayed reaction. Usually, the pain starts as soon as the feet warm up, but this time it was an hour or two later, and only on one toe.
I think Yvonne's been the most impressive, because she was able to run bare fairly consistently throughout the winter, and it seems like she can handle moisture pretty well. Most of my mileage has been on dry surfaces, and either at the beginning and the end of winter, or during my California trip in January.
My PR was a windchill PR, which isn't quite the same as a pure temperature PR. Still, it's amazing how much more doable those colder temps are when the surfaces are bone-dry. Now that my calluses are reforming, my tolerances are back to where they were earlier. This morning's run-commute at 11F felt positively balmy. I had to take off my gloves and balaclava, cuz there was no wind.
I thought you guys in Ottawa had more or less the same temps as we do. We've been dipping above and below freezing for a while now. We had a cold weekend, but today it's supposed to be up around 40F, and we should have above-freezing highs from here on out. Like you said, all we need now is for the street sweepers to mobilize!
Rain/snow is forecast for tomorrow, so I'll try to get in a longer run later today.
