How to Breathe While Running

It’s easy to get wrapped up in strategies for speed work, stretching or nutrition while training for a race. But many of us forget about an element of running that serves as a foundation for how fast and how far we can go: our breath.

The way you breathe while running is an important part of performing your best. So, how can beginning and advanced runners alike optimize their breathing to maximize running potential? Let’s take a closer look, with the help of a few coaches, including the elite coach, Dr. Jack Daniels.

Our respiratory system pumps oxygen into our bodies and pumps carbon dioxide out. This process becomes more crucial when we are exercising and the demand for oxygen increases.

A study published in the Journal of Applied Physiology found that inhaling and exhaling may account for up to 10 to 15 percent of energy demand during intense exercise, such as running.

When your body isn’t getting enough oxygen during a run, you’ll immediately notice it in your breath: you may be panting or breathing raggedly. But struggling for breath can have systemic effects on your body, even when you stop running. Your body produces lactic acid when oxygen levels are low, which in turn can cause muscle cramps and fatigue.

One way to ensure we are getting as much oxygen as possible is through a breathing technique called diaphragmatic breathing, or belly breathing.

Diaphragmatic breathing is a technique that uses your diaphragm—the large, dome-shaped muscle at the base of your lungs—to help move oxygen in and out of your lungs.

Using the technique can strengthen the diaphragm, decrease the amount of work it takes to breathe and decrease your body’s demand for oxygen, according to the Cleveland Clinic.

A good way to practice belly breathing is to lie down on the floor and place your hand on your belly. When you inhale, try to breathe so that your belly rises and lifts your hand.

Once you’ve got the hang of it, stand up and repeat the steps. With practice, you can train yourself to belly breathe while running, thereby increasing your ability to obtain and use oxygen.

As for whether you should be breathing in through your nose and breathing out through your mouth, or using both, many coaches encourage runners to use the breathing pattern that feels most natural.

“Do a five-minute steady run using a 4:4 rhythm the first minute, then change to a 3:3 rhythm the second minute, a 2:2 the third minute, 1:1 the fourth minute and again to a 4:4 rhythm the fifth minute,” he says. “Many won’t mind that 4:4 the first minute, but realize 4:4 isn’t good by the fifth minute. When on an easy run, 3:3 is a workable rhythm, but it isn’t good enough for a race.”

There’s a significant amount of research that’s been done on rhythmic breathing and running. The authors of one seminal 2013 study, Impact Loading and Locomotor-Respiratory Coordination Significantly Influence Breathing Dynamics in Running Humans, found rhythmic breathing aided in “reducing the work of ventilatory muscles, and minimizing fatigue of respiratory muscles that are critical to endurance aerobic activity.”

If rhythmic breathing supports running economy, is there an ideal rhythm we should be working toward? The short answer: It depends on an individual runner’s fitness level and goals. A beginner or intermediate runner on a long run may do well with a 3:2 or 3:3 pattern, while an elite runner racing in a 5K will likely favor a 2:2 or 2:1 pattern.

These three breathing techniques from Coach Nate will help keep you comfortable on your next run.

1. Breathing in and out through your nose

The first technique is to breathe exclusively in and out through your nose. This forces you to stand taller, activate your diaphragm and breathe into your belly. Try it for 3 to 5 minutes and run as slowly as you need to.

Nose breathing will be the most challenging but also the most important for you to master. Try to make nose breathing your default while walking, working, and reading articles like this.

2. Breathing in through your nose and out through your mouth

The second technique is to breathe in through your nose and out through your mouth, because you can’t breathe exclusively through your nose all the time. This technique is great for long runs and runs where you’re picking up the pace to a moderate effort

Even taking ten to 20 breaths in through your nose and out through your mouth mid-run can provide a helpful reset to your breathing mechanics.

3. Breathing in and out through your mouth

The final technique is to exclusively breathe in and out through your mouth – but with a catch! Mouth breathing is the default technique for most runners but, if practiced too much, it can lead to bad habits like breathing more through the chest and the shoulders than your diaphragm. Breathing this way can lead to side stitches, poor pelvic stability, an elevated heart rate and more erratic, panicked breaths.

When you breathe in and out through your mouth, make sure you’re still breathing deeply into your belly and diaphragm. Mouth breathing is great for harder race efforts when you’re really pushing as it allows you to take in as much air as possible, but it should only be used for when things get difficult.

By practicing these breathing techniques, you can ensure a more efficient and comfortable run. Which breathing pattern do you default to and which are you most excited to try? Write them down and make a plan to practice each technique for at least five minutes on your next run.

Although belly breathing and rhythmic breathing can significantly impact your running, it’s consistency in your training that will ultimately improve your fitness level and increase your body’s ability to utilize oxygen.

USA Track & Field-certified running coach Lou Ann Bakolia, who coaches through her company Off to Run, says consistency is key to becoming a better runner.

“The breathing will come with consistent training,” she says in an email to Fleet Feet. “They have to run at least three days per week.”

USATF coach Tim Clark also says proper breathing can help a runner’s recovery from a hard workout.

“A runner’s level of fitness, and ease of breathing go hand-in-hand,” Clark says in an email. “Therefore, the more fit one is, the quicker one’s recovery.”

Pay attention to your training schedule, focus on your breathing, and your upcoming race may feel a bit breezier.
