How to Breathe While Running: A Beginner’s Guide

“How do I breathe while running?” is a question almost every beginner asks, usually after a run where they felt constantly out of breath and couldn’t figure out what they were doing wrong. The good news is that breathing while running isn’t as complicated as it feels, and often, the real issue isn’t your breathing at all.

First: breathlessness is usually a pacing problem

Before we get into breathing technique, here’s the most important thing to understand. If you’re gasping for air almost immediately when you run, the most likely cause isn’t bad breathing: it’s that you’re running too fast.

New runners consistently run at a pace they can’t sustain, which leaves them breathless within a minute or two. No breathing technique will fix that, because the problem is intensity, not technique. The fix is to slow down, dramatically. You should be running at a pace where you could hold a conversation. If you can’t speak in full sentences, you’re going too fast, and that’s why you’re out of breath.

So before optimizing your breathing, slow your pace. That alone solves the problem for most beginners.

Breathe deeply, from your belly

Once your pace is under control, the main breathing tip is simple: breathe deeply, not shallowly.

Many people breathe shallowly from their chest, especially when nervous or working hard. Shallow breaths don’t move enough air. Instead, aim to breathe more deeply into your belly, let your stomach expand as you inhale. This is often called diaphragmatic or “belly” breathing, and it gets more oxygen in per breath, which helps you feel less winded.

You don’t need to force it or think about it constantly. Just relax, and let your breaths be full and steady rather than quick and shallow.

Mouth or nose?

Use both. Some beginners worry they should only breathe through their nose, but when you’re exercising, your body needs more air than the nose alone can comfortably supply. Breathing through your mouth (or mouth and nose together) is completely normal and fine while running. Don’t overthink it.

Try a breathing rhythm (optional)

Some runners find it helpful to tie their breathing to their steps, for example: breathing in for a few steps and out for a few steps. This can create a steady, calming rhythm and stop your breathing from becoming ragged.

This is optional. If it helps you settle into a groove, great; if thinking about it feels like a distraction, don’t bother. A relaxed, natural rhythm is the real goal.

Relax the rest of your body

Tension makes breathing harder. Clenched shoulders, a tight jaw, or balled-up fists all waste energy and can make your breathing feel more labored. Every so often during a run, do a quick check: drop your shoulders, relax your hands, unclench your jaw. Loose and relaxed breathes easier.

The bottom line

If you’re constantly out of breath when running, slow down first — most beginner breathlessness is a pacing problem, not a breathing one. Once your pace is conversational, breathe deeply into your belly, use your mouth freely, stay relaxed, and optionally settle into a step-based rhythm.

Breathing while running isn’t a technique you have to master before you’re allowed to run. Slow down, relax, and it largely sorts itself out.
