Your legs have more in them. Your breathing says otherwise. If your lungs are the first thing to tap out on a tempo run or a long effort, you're not alone, and it's one of the most trainable parts of your running.
In this blog, you'll learn how to breathe better while running, why your tongue plays a bigger role than you'd think, and which running endurance tools help you breathe easier over the miles.
Five Ways to Breathe Better on Your Next Run
Breathing efficiency during exercise comes down to a few simple habits. Start with these.
1. Run Your Easy Days Easy
If you can't get a full sentence out, you're going too hard for an easy run. Slow down until you can talk in short sentences. Your breathing settles, and you still build fitness.
2. Breathe From Your Belly
Shallow chest breaths fill up fast and leave you gasping. Let your belly push out as you breathe in, and pull it back in as you breathe out. It feels odd at first, then it becomes automatic.
3. Match Your Breath to Your Stride
A steady rhythm keeps you from gasping. On easy runs, try breathing in for three steps and out for two. When the effort picks up, switch to in for two, out for one.
4. Use Your Nose on Easy Runs
Easy miles are a great time to practice breathing through your nose. On hard efforts, breathing through your mouth as well is completely normal. Use whatever keeps you relaxed.
5. Relax Your Shoulders
Tight shoulders make for tight breathing. Every mile or so, drop your shoulders, shake out your hands, and reset.
Why Your Tongue Is Part of the Answer
Most running tips skip one thing: your tongue sits right in the path of every breath you take.
When your tongue slides toward the back of your mouth, it can crowd the space air needs to move through. When it rests forward, that path stays more open. Try it right now. Let your tongue drop back and take a breath. Then rest it on the roof of your mouth, just behind your front teeth, and breathe again. Feel the difference?
How a Performance Mouthpiece Helps You Breathe Better
Thinking about your tongue for an entire run isn't realistic. That's where a performance mouthpiece earns its spot.
AIRWAAV lowers respiratory rate by up to 20% (peer-reviewed). Its patented intake bar gives your tongue a spot to sit forward as you bite down, and the design helps position your jaw to open your airway. That's the idea behind AIRWAAV's Breathe Better to Endure Longer benefit. After a long effort, it supports Stay Calm to Recover Faster too, since AIRWAAV reduces post-exercise cortisol by up to 50% (peer-reviewed).
Both are built on 15+ years of peer-reviewed research, developed in collaboration with Dr. Dena Garner, a researcher in muscle physiology and airway performance.
Long runs mean long wear time, so comfort matters most. If you'd rather barely notice it, PX1's relaxed, open fit is a natural match. If you like it held firmly in place, go PX2.
Can't decide? The Performance Hybrid Pack gives you both, so you can try each on the road.
Running Endurance Tools That Help You Breathe Easier
Good form does most of the work. The right gear makes it easier to hold onto, mile after mile:
-
A heart rate monitor: It helps you keep easy runs truly easy, so your breathing stays under control.
-
A steady beat: A metronome app or a playlist with a steady tempo makes it easier to lock in your breathing rhythm.
-
Nasal Strips: AIRWAAV Nasal Strips support nasal breathing on easy miles, and the enhanced adhesive holds through sweat and 8–10 hours of wear.
-
A performance mouthpiece: It keeps your jaw and tongue in a good spot for breathing, so you don't have to think about it.
Pair Nasal Strips with your Performance Mouthpiece, and you've got the Performance System, a dual-airway advantage in training.
Tips for Your First Few Runs With a Mouthpiece
A little setup helps it feel natural fast:
-
Fit it first: Follow the how-to-fit & use guide before your first run.
-
Start with easy miles: Wear it on a short, easy run before a long run or a race.
-
Give it a few runs: Breathing with a mouthpiece takes a little getting used to.
-
Test it before race day: Save new gear for training until it feels like second nature.
Before long, it'll feel like a normal part of your running kit.
FAQs
Should I breathe through my nose or mouth when running?
Both work. Nose breathing is great practice on easy runs, and adding your mouth on harder efforts is normal. Go with what keeps you relaxed.
Why do I get out of breath so fast when running?
Usually, your pace is outrunning your breathing. Ease off a little, build more easy miles, and your breathing will catch up.
Can I run with a performance mouthpiece in?
Yes. The AIRWAAV Performance Mouthpiece is built for training, including long runs. Pick the fit that feels best over the miles.
Is PX1 or PX2 better for running?
Neither. They have identical performance benefits. PX1 feels lighter, and PX2 feels more locked in.
Can I use my HSA or FSA?
Yes. AIRWAAV is HSA/FSA eligible.
Breathe Easier on Every Run With AIRWAAV
Better breathing on a run comes down to a few simple moves: an easier pace when you need it, belly breaths, a steady rhythm, and an open airway. Your tongue is part of that last one, and it's the piece that's easiest to overlook.
Practice the habits, then let the right gear help you hold them over the miles. Go PX1 for a relaxed fit, PX2 for a locked-in fit, or the Hybrid Pack to try both, and add Nasal Strips for the full Performance System.
