How to Breathe While Running

If you’ve ever found yourself gasping for air during a run, you're not alone. Many runners whether beginners or seasoned athletes struggle with breathing properly while jogging or sprinting. The good news? Learning how to breathe more efficiently can improve your running performance, reduce fatigue, and help you recover faster.

Here’s what you need to know about breathing while running, and how to train your breath for better results.

Why Proper Breathing Matters During a Run

When you run, your muscles demand more oxygen to keep moving. The harder you work, the more carbon dioxide you produce making it essential to maintain a breathing pattern that balances oxygen intake and carbon dioxide output. Poor breathing can lead to side stitches, early fatigue, or even dizziness.

But when you breathe properly:

• You improve your body’s oxygen efficiency

• You reduce tension in the shoulders, neck, and chest

• You enhance stamina and endurance over time

• You recover more easily post-run

One study found that endurance athletes who used breathing training had significantly improved performance over a six-week period, highlighting just how impactful better breath control can be.

Mouth vs. Nose Breathing: What’s Best?

While nose breathing can help filter and humidify air, most experts agree that mouth breathing is best during moderate to high-intensity runs. It allows you to take in more air with less effort, helping you meet the oxygen demands of your working muscles.

That said, during warmups or slower recovery jogs, inhaling through the nose and exhaling through the mouth can help regulate your pace and calm the nervous system.

How to Coordinate Your Breath With Your Stride

Using a breathing rhythm, or breathing in sync with your steps, helps create a more natural, consistent pattern especially during longer runs.

Try these popular breathing ratios:

• 3:3 pattern (inhale for 3 steps, exhale for 3 steps): Ideal for easy runs or warmups

• 2:2 pattern (inhale for 2 steps, exhale for 2 steps): Common for moderate efforts or tempo runs

• 2:1 or 1:1 pattern (inhale for 2 steps, exhale for 1; or equal steps for each): Useful for sprints or hill climbs

Experiment with different rhythms until you find one that feels sustainable and aligns with your pace.

Diaphragmatic Breathing vs. Chest Breathing

Many runners unknowingly take shallow, rapid breaths from the chest. This can limit oxygen intake and lead to tension. Instead, focus on diaphragmatic breathing deep breathing from your belly to maximize lung capacity and oxygen delivery.

How to practice:

1. Lie on your back with one hand on your chest and the other on your abdomen.

2. Inhale deeply through your nose, aiming to expand your belly more than your chest.

3. Exhale slowly through your mouth.

4. Practice for 5–10 minutes daily and gradually incorporate into your running.

Over time, diaphragmatic breathing can improve endurance and reduce shortness of breath, especially for distance runners.

Try This: Breathing Drills for Runners

Incorporate these drills into your routine to improve control and efficiency:

• Box Breathing: Inhale for 4 counts, hold for 4, exhale for 4, hold for 4. Great for calming pre-run nerves.

• Pursed-Lip Exhalations: Inhale through the nose and exhale slowly through pursed lips. This extends the breath and can reduce anxiety or tension.

• Rhythmic Stride Practice: While walking or jogging, time your breath with your steps to build awareness.

Managing Shortness of Breath on Runs

If you find yourself breathless early into a run:

• Slow your pace and walk if needed

• Focus on long, deep breaths rather than shallow pants

• Check your posture stand tall to allow full lung expansion

• Use a rhythmic pattern to settle your breath

Remember, your body needs time to adapt. Give yourself permission to take it easy while you train your lungs just like you would your legs.

When to See a Doctor

While breathlessness can be part of building endurance, it shouldn’t be extreme or persistent. If you notice:

• Wheezing or tightness in your chest

• Coughing fits during or after running

• Sudden dizziness or shortness of breath at rest

It may be time to speak with a healthcare provider. Conditions like exercise-induced asthma or other respiratory issues may require treatment.
