Rounding the turn toward Coolidge Corner, Kimberly Romanello felt like she didn’t have any gas left in the tank. Scene: Boston, her first-ever marathon, mile 22, April 17, 2017. Her head hurt. Her feet ached. Sweat pooled down her back, saturating her Multiple Myeloma Research Foundation mesh tank. Gazing into the sign-wielding crowd, her breath labored, she paused for a moment.

“I had a minute there when I was doubting everything and why I had signed up in the first place,” reflects the 30-year-old Bostonian. “But then, I thought about the pain that my loved ones experienced throughout their battles with MM. And that’s when my running mantras came into play.”

A subset of self-talk, a mantra is a single word or short statement repeated frequently to aid concentration or help accomplish an objective. Romanello’s go-tos are common for runners: a simple “You got this,” or “Run with your heart.” Shutting down her inner uncertainty wasn’t easy, but shifting her focus to these positive statements ultimately helped her finish her first marathon in just under five and a half hours.

“Thoughts affect feelings, and feelings affect performance,” explains Jim Afremow, Ph.D., sports psychology expert in Phoenix and author of . “Change your thinking, and you’ll change your performance.”

If that sounds almost too easy, know that there’s plenty of research to back it up. According to a study in Medicine & Science in Sports & Exercise, motivational self-talk can reduce perception of effort and increase endurance, which may lead to a leg up on the competition. In the study, recreational cyclists who learned to use motivational self-talk statements could cycle 18 percent longer than they’d been able to before implementing this strategy. They also had a lower rate of perceived exertion than those who didn’t engage in positive self-talk. Put into running terms: A few happy thoughts could help you push your usual 30-minute run to 35 minutes with ease.

“Your mind can be your weapon or your weakness.”

So, yes, mantras can actually make a big difference. But not just any old saying will get the job done. The language you use in that short and sweet pep talk makes a major impact. “Your mind can be your weapon or your weakness,” says Lenny Wiersma, Ph.D., a professor of sports psychology at California State University in Fullerton who’s worked with athletes from UFC fighters to ultramarathoners. “It’s a weapon when we’re utilizing it to draw on banked energy, allowing us to dig a little deeper and enjoy an experience more. It’s a weakness if we aren’t aware that what we are saying can negatively change our perception of difficulty or distract us.”

For example, instead of focusing on what’s going wrong mid-stride, home in on positive statements. Swap out something like “I hate hills” for “You can crush hills.” When mile nine of a half marathon feels impossible, ditch the “I suck at this distance” thoughts for an affirming “You’re crushing this distance” mantra. As Afremow says, “You’re the one who’s capable of changing the script to your running story.”



Swap Out “I” for “You”

Using the word “I” can stress you out instead of helping you regulate your feelings and behavior, according to a study in the Journal of Personality and Social Psychology. Make your words more effective by talking to yourself like you’re someone else, Wiersma says. Take it a step further by bringing someone you care about or admire into focus. “Imagine someone who is powerful saying your mantra,” he suggests. “Hear their voice. It’ll take a simple technique to the next level.”

Say It Out Loud

Starting to fatigue? Bring your mantras to life by voicing them—even quietly. Trust us, the weird stares are worth it. One study found that basketball players passed the ball faster when they motivated themselves out loud, and that the strategy worked for any task based on speed, strength, or power.

Use the Immersion Technique

Once you settle on what your go-to motivational phrases are, amp up their impact by surrounding yourself with the sayings from morning to night, especially in the weeks and days leading up to a race or competition. Try embedding them in your email signature or on your phone’s home screen. Share them on your social media. Then, repeat your running mantras to yourself periodically while spending three to five minutes visualizing yourself as the runner you want to be. “It’ll help you to reinforce the way you want to think, feel, and run,” Afremow says.

Edit Yourself

We all have a friend who swears like a sailor (and maybe that friend is you). While it’s one thing to use profanity in jest with your buddies, it’s another to make that type of language commonplace in your mantras. Because profanity has a negative connotation, many people don’t react well to that type of degrading talk, Wiersma says. Be aware of how expletives make you feel, especially on repeat. It can be a powerful tactic for some, he adds, but most are better off avoiding obscenities altogether.

Match Your Mantra to the Moment

Have different running mantras that you can use at different points of your race or distance so they don’t lose their power, Wiersma suggests. So, one for mile two of a 10K, but another for mile eight. “This way, it won’t become background noise,” he says. “Reserve those chosen few for when you really need to dig deep.”
