VO2 max is considered the "gold standard” predictor of longevity; one study involving more than 122,000 participants found that a high VO2 max was associated with a lower risk of dying from stroke, cancer, diabetes, and other health conditions. And for athletes, an improvement in VO2 max indicates that their training is working.

But VO2 max doesn’t offer a comprehensive assessment of your running ability. And obsessing over VO2 max—or any single metric, for that matter—can be detrimental to your training and take away from your enjoyment of the sport. To help put VO2 max in perspective, we consulted with coaches and exercise physiologists. Head to the link in bio for what you need to know.

While many of us would do anything—including training in the AC on a treadmill—to avoid running in the heat, our bodies know exactly what to do in these conditions. And new science says getting a little toasty may be good for our overall health.

As a standout middle-distance runner at Portsmouth Abbey High School in Massachusetts, @margotappleton relied on her trusty Timex watch. These days, as a pro running with @newbalance, she still logs most of her miles on a Timex.

She's not alone—Olympians @fiona_okeeffe and @heather_maclean31 have shared their preferences for low-tech watches. So what makes these high-level athletes want to forgo all the data at their disposal for something simpler—and should recreational runners follow suit? Read the full story at the link in bio.

As peak thunderstorm season approaches, you probably know to check the weather forecast before you head out the door for a run. During warmer months, however, pop-up thunderstorms can often form sporadically without much prior notice.

So, what can you do to stay safe? We talked to meteorologist and marathoner @johnburchfieldweather to learn the top tips for runners caught in severe weather. Link in bio!

Even a 1% increase in pelvic drop, a movement pattern in which the pelvis doesn’t remain level when the body is supported on one leg, can boost injury risk by as much as 80% if left untreated.

The good news is that it’s treatable. At the link in bio, learn from the experts how you can solve Trendelenburg Gait Syndrome (or TGS) to get back to running injury-free.

No matter what your experience level, if you’re looking to race well in shorter distance races, there’s nothing like a track ladder.

These intervals, which feature short, quick bursts of energy, give you a fitness boost that will make you feel unstoppable in your 5K or 10K. Head to the link in bio for the full workout plan.

At 25 years old, @jakobing still has plenty of time to continue his running dominance in the years ahead. But, after getting surgery to repair a longstanding achilles issue in February, he also senses that rushing a return could set him back once more.

"The last couple of months have been about making sure the build-up has been as slow and progressive as possible," the Norwegian runner told @sarahwassnerflynn. How is he managing his return to peak fitness with fatherhood and recovery? Read the full story at the link in bio.

Here’s an ugly truth: Pace shaming is real.

In a sport that is supposed to welcome all speeds and levels — where the overall vibe is usually one of positivity, pride, encouragement, and sometimes even awe — there are too many dismissive voices that may not understand the damage they could cause.

On a psychological and health level, shame-based language can have lasting, harmful effects on a person’s brain and body, neuroscientist @dr.dayagrant writes. Head to the link in bio to learn how.

If you’ve been paying any attention to running news over the past week, you’ve probably seen what @rachel__entrekin just did.

Last Wednesday, the 34-year-old from Birmingham, Alabama completed the @cocodona250 faster than anyone, man or woman, ever has, running at an average 13:28 minute mile pace for just over 56 hours. That includes approximately 19 minutes of sleep, a series of five to ten minute aid station stops, and power hiking up the race’s 38,000 feet of vert.

As she balanced celebration and rest following her historic finish, @davidgleisner had the chance to sit down with Rachel in two post-race interviews to hear the story of the 2026 Cocodona 250 from her point of view. Read the full profile at the link in bio.

Let’s be real. Runners are the worst at stretching, especially when that stretching requires an hour-long session, in a yoga studio, across town, that costs money.

But a little yoga can go a long way for stiff-limbed runners. We asked our friends at @yogajournal for the must-do stretches they'd prescribe for every runner. Learn how you can use them to improve your running at the link in bio.

After more than five days of running from Black Canyon City to Flagstaff, Arizona, the final finishers of the @cocodona250 have crossed the line.

In the final hour before the 125-hour cutoff, known as Golden Hour, finishers included:

-Ashley Livingstone, second Cocodona 250 finish
-Missy Hendricks @ellicul_lucy (Mescalero Apache), second Cocodona 250 finish
-Greg Secatero @secateroendurance (Diné), fourth Cocodona 250 finish
-Robby Chaney @runrobbyrun, second Cocodona 250 finish (final finisher in 2024)
-Wayne Amo, first Cocodona 250 finish and unofficial DFL

After being tended to by the medical team and getting an IV, Wayne Amo said he was “feeling much better.” Congrats to all the @cocodona250 finishers!
