Okay, so this isn't me. I found this picture on the internet and it was taken in temperatures of -60C which does put things in perspective a bit...
But still, I think Minus Four this morning is the lowest temperature I've run in. It was beautiful, though, to be out and to see the sun "sort of" come up through the freezing fog. The bushes and trees were a bit like this chap's eyelashes are here. I'm so glad I went.
To try and offset the cold-induced asthma, I wore my buff over my mouth for the first third of the run, until it got too damp with the moisture from my breath, at which point I tucked it under my chin.
Two things happened when I got home.
1) I fell up the front steps. I was entirely unhurt, except for my pride which was very hurt indeed. Mind you, it serves me right as I was just entering that very smug state I sometimes get into post-run. I live in a busy road and at that time in the morning the world and its spouse were on their way to work so plenty of people saw me...
2) When I went to take my buff off, I initially couldn't. The moisture on it had frozen solid.
