I take it as a sign that humans really are a tropical species that most of us hate winter.

A ski mask wouldn't make you look like a terrorist.

I adapted a workshop spark mask as a face protector for cycling. It does not insulate, but it does keep the wind off, in very cold areas it will also perhaps need wiping to stop it misting and freezing. I had to sow extra buttons on to the hat of course.

You should have stayed home, have a cup of tea and a nice fattening cake.

Why not run indoors? Surely there is a gym there somewhere?

Running in the cold is invigorating to say the least...scarf or ski mask would help. Only thing I didn't like was my toes getting frosty the instant I stopped. Enjoy the winter wonderland, we never get those in southern Alablamama we did get about 4" back in 2011...I was working at one of the hospitals and 2...yes TWO locals were brought in with broken bones...for trying to ride their Harleys in the snow...both were in total denial, each claiming "I could handle it"...to which I asked, " and you are in here becauuuuse???"...you could have heard a pin drop...smfh

Your ski mask observation may be sadly accurate. Many years ago late on a cold windy winter night I walked to the YMCA (my gym) wearing a dark brown ski mask. When I crossed the major street between the YMCA and a huge church, an old car with an idiot young white man stopped in the middle of the road. He rolled down his windows and yelled (over and over) "Hey you fucking nigger! Go back to Africa you fucking monkey . . . . . etc etc. I am not dark skinned.

On another cold winter night, wearing a ski mask, as I was entering the YMCA several patrons who were leaving displayed profound fear when they saw me. They acted like I was going to kill them.

As for figuring something out, I have found wearing an N-95 mask is very warm when running between buildings.
