It was the proverbial brass monkeys when I headed out on my run (the outdoor thermometer by the kitchen window said 2ºC, when I came back and got in the car it said 0ºC). I kept a buff over my mouth for most of the run. Initially this was just to keep warm, but as I hit Summerhill Road it was full of cars, so offered a little protection against the fumes. Lots of dodging people on the pavements, I will have to remember my runbell if I want to run this route at this time of day again.
