Does your breathing hurt while running in Winter?
Cold, dry air can cause real discomfort for many runners during the winter months, but don’t let that stop you from getting your runs in.
Give it time - you may find your body will adapt and become better at processing the cold air. Try slowing down the pace while you’re going through that transition. Give it a month. If it’s still giving your problems, not all is lost. Simply make sure your well hydrated all winter long and try wearing a balaclava to cover your mouth and nose, that should help. When doing that, go through periods in the run where you pull the balaclava down and practicing take in the cold air without the balaclava filter.
