CIRCLE WITH A DOT

@officehippy I have a mask called Airtrim that I use if it gets very cold, you look like Darth Vader but it does warm up the air and keep your face warm

@officehippy is it the one in Äkäslompolo? Cool, it's very beautiful up there! I ran a 100K race there a few years ago, but in summer. I have ran there in winter as well but not for a race. My profile photo is from the same place.
You will want shoes with spikes I think, they don't need to be extra warm, I find feet stay warm anyway unless they get wet. Wear layers of socks, preferably wool, instead. If you are not used to breathing cold air you could look into getting a mask of some kind also.
