Brr! Not exactly toasty this morning.

Not sure how trail runners in Siberia deal with this or worse. Assuming there are Siberian trail runners.

It really isn't much different than 0 degrees. You have to just bundle up and cover your face.

Is it even safe to breathe cold air like that? One time I ran when it was 7 degrees. I lasted ~15 minutes then thought maybe my lungs were going to ice over.

Ya, it's quite safe. It takes about 20:00 of constant exposure at -17 (0mph wind) to cause frostbite and your bronchi are neither exposed to air that cold nor for more than a second or so. There is such a thing as cold air induced asthma when your airways constrict. Dress correctly and it doesn't feel any different than 0 degrees or even +20 degrees.

And I know those numbers because before I headed out this morning I looked it up!
