Okay, I am NOT a runner, but I do it because I'm not 18 anymore and cardio is required to stay fit. I know my limits, and I've been able to extend those limits with patience and persistence. But, now that the temps have dropped in our area, I'm struggling. I find that a mile into my runs I'm breathing hot daggers into my lungs, and my chest continues to throb after my runs, too. I drink warm water when I get home. That seems to help a little, but it's very discouraging. Is this just something that you get over? Is there a breathing technique that I don't know? HELP!!
It may be something you can get used to, depending on temperature, but some people have problems in cold air. Meanwhile, you can get a neck gaiter or a scarf or a ski mask/balaclava to cover your mouth and/or nose. It makes it a little harder to breath but definitely helps with the temperature. I have a thin balaclava that I use when temps get to the low 20s/teens.
What did the trick for me is wearing it only over my neck, surprisingly enough, even though I stil take in the cold air it does not hurt as it used to. In very cold days, I wear it also over my nose and mouth as lenzlaw suggested, but I try not to as I find it quite unconfortable.

Recently running half marathons. Six completed so far. Now looking for number 7. Once I get to 10 I will start thinking about full marathons.
