Running today it was cold, -1c, feels like -6c. I hadn’t checked the weather. I did not think about it, but the canal was frozen over in parts, and it snowed.
I wore a thin vest, a merino running jacket and a thin black gillet. It was quite slippy, but after the first few minutes I was not cold. I might helpfully have worn gloves for the first mile or so, but otherwise it was fine.
Had I known, I would have overdressed. Had I stopped, I would have been underdressed, but as it was, it was fine.
