Breathing is the process of taking in oxygen to fuel your running, and there are right and wrong ways to do it. If you’re currently breathing incorrect during your training, you could slow down your progress. Even if you don’t feel like it is difficult to breathe when running.
Are you taking in air via nose or mouth while running? There are so much controversial out there regarding to the running breathing technique. The best answer should be pick up the technique that you feel most comfortable with since no one understand your body better than yourself. A simple rule is, breathing via your mouth while running in high intensity since it helps to take more air in, while you doing a long run say half or full marathon at a slower pace, you can breath via nose. Breathing via nose help you to be able to talk while running, even carry on the full sentence in your conversation.
For me mouth breathing is by far the best way to breath while running, largely because it brings in more oxygen than breathing through the nose.
Anyway, just breathe and running. It doesn’t matter whether you’re breathing out of your nose or your mouth while you run, the most important is get yourself moving. When you’re training hard, you’ll have to breathe through your mouth to take in enough oxygen.
