Recently, while sifting through some of the excruciatingly detailed performance data he'd collected over decades as a Colorado-based triathlon coach, Alan Couzens noticed a pleasing symmetry. All else being equal, the amount of aerobic fitness his athletes lost by getting a year older was almost identical to the amount they gained by adding an hour per month of training time. Want to freeze the biological clock from one birthday to the next? Find a spare 15 minutes per week and fill it with running.

The long-haul practicality of this approach is debatable: after a decade, that additional training time would total 2.5 hours a week. But the underlying premise of what we might call the Couzens Immortality Quotient taps into a fertile area of debate. How much of the aging process is an inevitable slide into decrepitude, and how much is a result of not getting enough exercise?

That's the question Johannes Burtscher of the University of Lausanne, along with colleagues in Switzerland and Austria, posed recently in the International Journal of Environmental Research and Public Health. By pooling the results of more than a dozen studies, the group reached an encouraging, quantifiable conclusion: only about half of the fitness losses suffered by endurance athletes as they get older are attributable to the passage of time. The other half can be chalked up to reduced training.

The standard gauge of aerobic fitness is VO2 max, which measures how quickly you're able to breathe oxygen into your lungs, pump it through your arteries, and use it to help fuel muscle contraction. It's expressed in milliliters of oxygen per kilogram of body weight per minute, and in young adults it typically hovers somewhere in the forties. After age 25, it declines by about 10 percent each decade, dropping more quickly in your sixties and seventies. Among endurance athletes, the numbers aren't so predictable. Some studies find losses of 5 percent per decade; others as much as 46 percent. What accounts for the difference? The extent to which you continue training as you get older. After all, the fitter you are, the more you stand to lose.

The effects of ceasing training entirely seem to be similar in athletes of all ages. Your VO2 max begins to plummet within a few days of stopping exercise, and you might lose as much as 20 percent after 12 weeks. These losses are explained mostly by changes in how much blood your heart can pump with each beat; the good news is that the trend can be reversed fairly quickly when training is resumed. Other age-related changes, such as stiffening arteries, occur more slowly and are harder to undo.

How much of aging is an inevitable slide into decrepitude, and how much is a result of not getting enough exercise?

When Burtscher and his colleagues ran the numbers, they found that 54 percent of the variation in fitness loss by male endurance athletes was explained by differences in how much they trained. That number in women was 39 percent, but the scarcity of data for female subjects makes it impossible to tell whether there's a real physiological difference between the sexes. Overall, the data fits with the observation that athletes who keep training at a fairly constant level over the years lose about 5 percent per decade-half as much as the typical nonathlete.

There are a couple of key questions raised by these findings. The first one: If you miss a year, or a decade, can you get back to where you were? Or is some of that fitness lost forever? There's no research to suggest a solid answer, according to Gregoire Millet, one of Burtscher's colleagues at the University of Lausanne. It probably depends to some degree on how much you trained prior to stopping, and for how long. The risk upon resuming would be that your bones and connective tissue are no longer prepared to handle a heavy load, making you more susceptible to injury.

Still, there are some encouraging hints in the literature. In 2020, researchers published lab data on Tommy Hughes, an Irish man who'd recently run an eye-popping 2:27 marathon at age 59. Hughes's VO2 max was 65.4, more than twice what you'd expect from a largely sedentary man his age. Not surprisingly, Hughes was a former elite marathoner; he competed at the Barcelona Olympics in 1992. But he'd taken a 16-year break from running, starting again at the age of 48. We can't know for sure if that pause hurt him-if it did, it couldn't have been by much, given that he currently holds the world marathon record for the 60-to-64 age group, at 2:30:02.

The other question is how to maintain your training level as the years pass. We all have good intentions, but real life rarely resembles the smooth aging curve that results from graphing the average data from large groups of people. Instead, there are plateaus and gentle declines punctuated by steep drops-you break a leg, your first kid is born, you become addicted to social media, and so on. Avoiding periods of rapid decline goes a long way toward slowing the overall slide.

Another superstar case study, this one published in 2022 by a team led by Bas Van Hooren of Maastricht University in the Netherlands, illustrates the benefits of consistency. A 75-year-old middle-distance runner named Hans Smeets, who holds multiple European and world age-group records, had clocked a VO2 max of 50.5, equal to the highest known measurement for his age. Smeets only began running at 50, further evidence that it's never too late to start (or start again). And once he'd begun, he kept going. Over the next 25 years, he never missed more than a week of training. Initially, he ran more than 85 miles per week, and at 75 he was still logging as many as 50. He attributed his ability to handle all that mileage without injury to doing most of his runs at, in his words, "an easy pace."

That, as it turns out, aligns perfectly with Couzens's view about what's required for long-term athletic success: lots of low-intensity exercise. To be sure, the idea of adding an hour of training per month every year to ward off the effects of aging sounds suspiciously like an endurance version of the legend of Milo of Croton, the ancient Olympian wrestler said to have lifted a calf over his head every day until it was a full-grown bull. In both cases, each step in the process seems simple, but the result is nonetheless improbable, let's call it.

Yet, as an aspiration, or simply as a formulation of what's possible, the Couzens Immortality Quotient tells us the same thing as the examples of Tommy Hughes and Hans Smeets, and as Johannes Burtscher's meta-analysis. You don't train less because you're getting old; you get old, to a surprising extent, because skipping that long Sunday run with your pals becomes a habit instead of a rare exception. Don't do it.

Some victories are measured by finish times. Others are defined by the obstacles overcome simply to reach the starting line.

For American Paralympic swimmer Ali Truwit, completing the New York City Marathon represented far more than covering 26.2 miles. It was the culmination of an extraordinary journey of survival, resilience, and unwavering determination that began with a life-altering shark attack just two years earlier.

On a crisp November morning in 2025, Truwit crossed the iconic finish line wearing a carbon-fibre running blade, fulfilling a promise she had made while recovering in a hospital bed after losing her lower left leg. The emotional milestone marked another remarkable chapter in one of the most inspiring comeback stories in modern sport.

The road to that unforgettable finish began only days after Truwit celebrated a major personal achievement. In May 2023, she completed her first marathon in Copenhagen alongside her mother. Just ten days later, while enjoying a graduation trip to Turks and Caicos with former Yale swimming teammate Sophie Pilkinton, tragedy struck.

While the pair were snorkelling, a shark attacked Truwit, severely injuring her left leg. Displaying remarkable courage, the two swam approximately 55 metres back to their boat, where Pilkinton—then a medical student—quickly applied a tourniquet that stopped the bleeding and ultimately saved Truwit's life.

Doctors were forced to amputate her lower left leg on her 23rd birthday.

Even in the darkest moments of recovery, Truwit's determination never disappeared. Reflecting on having recently completed her first marathon, she joked with one of the first responders that at least she had managed to run a marathon before the attack. The responder's simple but powerful reply would remain with her throughout rehabilitation: "You'll run another one."

Those words became a source of hope during the long and demanding road back.

Only weeks after surgery, Truwit began learning to walk on a prosthetic limb before gradually returning to the swimming pool. The process was anything but straightforward. The water that had once been her sanctuary became a source of painful memories, yet she refused to allow fear to define her future.

Her relentless work ethic soon produced extraordinary results.

Less than 16 months after the attack, Truwit represented the United States at the Paris 2024 Paralympic Games, producing a sensational performance to claim both silver and bronze medals. Standing on the Paralympic podium was a powerful reminder of how far she had come in such a short period, and she dedicated those achievements to everyone who had helped save her life.

Still, another dream remained unfinished.

The New York City Marathon carried deep personal significance. It was not merely another endurance event but a symbolic return to the city where her life had changed forever. On November 2, 2025, she lined up in Staten Island accompanied by 13 family members and close friends, all proudly representing her nonprofit foundation, Stronger Than You Think. Among them was Pilkinton, the friend whose quick thinking had preserved her life on that unforgettable day in the Caribbean.

Together, they covered every mile of the marathon before celebrating an emotional finish that Truwit later described as being "over the moon."

Completing a marathon on a carbon-fibre running blade presents challenges far beyond those faced by able-bodied runners. The prosthetic demands greater strength from the hips, core, and remaining leg while requiring exceptional balance, coordination, and endurance. Truwit's preparation combined months of disciplined training, patience, and mental resilience as she effectively taught herself how to run again.

Her story extends well beyond medals and marathon finishes.

Inspired by her own recovery, Truwit founded Stronger Than You Think, a nonprofit organisation dedicated to helping individuals overcome physical and financial barriers following limb loss. Recognising that sports prosthetics can cost tens of thousands of dollars and are often not covered by insurance, the foundation provides financial assistance for prosthetic devices, supports water-safety education, and promotes opportunities within Paralympic sport.

The organisation has already helped provide more than 11 prosthetic limbs, delivered nearly $200,000 in direct support, and funded over 4,000 hours of water-safety lessons benefiting more than 700 young people.

Throughout her journey, Truwit has remained refreshingly honest about the emotional challenges that continue to accompany recovery. She has openly acknowledged that healing is an ongoing process and that grief can still come in waves. Rather than portraying an effortless comeback, she has demonstrated that resilience is built through persistence, even on the hardest days.

Her remarkable transformation resonates far beyond elite sport. While few people will ever experience the trauma she endured, countless runners and athletes understand the frustration of injury, disappointment, or rebuilding after adversity. Truwit's journey serves as a powerful reminder that recovery is rarely linear and that courage is often measured by the willingness to keep moving forward despite uncertainty.

Now looking ahead to the Los Angeles 2028 Paralympic Games, Truwit continues to redefine what is possible. She is no longer known simply as the swimmer who survived a shark attack. She has become a Paralympic medallist, marathon finisher, advocate, and symbol of resilience whose story continues to inspire athletes around the world.

Her journey proves that while life can change in an instant, so too can the strength of the human spirit. Sometimes the greatest triumph is not returning to the person you once were, but discovering someone even stronger than you ever imagined possible.

Sprint and hurdles superstar Sydney McLaughlin-Levrone has entered an exciting new chapter in her remarkable life, welcoming her first child with husband Andre Levrone. The four-time Olympic champion and women's 400m hurdles world record holder announced the birth of their daughter, Savannah Michelle Levrone, who was born on Sunday, July 12, 2026.

The couple shared the joyful news with an emotional message celebrating the arrival of their daughter and expressing gratitude to everyone who supported them throughout the pregnancy. Sydney described Savannah as "our blessing and our joy," while expressing excitement and faith for the future that lies ahead for their growing family.

The announcement marks a deeply personal milestone for one of the most accomplished athletes of her generation. Renowned for redefining the women's 400m hurdles through a succession of record-breaking performances, McLaughlin-Levrone now embraces a new role beyond the track as a mother.

The timing of the announcement adds another layer of significance. Just days earlier, Sydney reflected on the 10th anniversary of qualifying for her first Olympic Games at only 16 years old—a breakthrough that launched one of the most decorated careers in modern athletics. Ten years later, her journey has come full circle with another life-changing milestone, underscoring that her greatest moments continue to extend beyond sporting success.

The arrival of Savannah Michelle Levrone has been met with an outpouring of congratulations from athletes, fans, and the wider sporting community, who have celebrated the couple as they begin this new chapter together.

Morocco's Zineddine Ouria claimed victory in a superb 2:08:49, with Kipchoge finishing 9 minutes and 50 seconds behind the race winner after navigating the demanding course in Porto Alegre.

Kipchoge began the race with controlled and confident pacing, reaching 5km in 15:34 before passing the halfway mark in 1:05:07. As the race entered its decisive stages, the pace gradually slowed, but the veteran marathoner pressed on with characteristic determination, completing the 42.195-kilometre challenge in 2:18:39.

For many, the story will be told through the finishing position. But for those who truly understand greatness, this journey is about far more than medals, records, or podium finishes. Kipchoge's World Tour is a celebration of the sport itself—an opportunity to connect with runners across every continent, inspire the next generation, and continue living by the philosophy that has become synonymous with his career: "No Human Is Limited."

The Brazilian appearance also carried added significance, coming shortly after Kipchoge was permanently honoured in Porto Alegre with his footprints unveiled at the entrance of Parque Harmonia—a lasting tribute to his extraordinary impact on distance running and his enduring legacy in the sport.

Once a champion. Forever an inspiration. Legends do not stop inspiring when the victories become fewer; they inspire because they never stop showing up. Through every stride, every finish line, and every challenge embraced, Kipchoge continues to prove that true greatness is measured not only by what an athlete wins, but by the lives they touch along the way.

With the second stop of his World Tour now complete, Kipchoge will turn his attention to the next chapter of his global adventure when he lines up at the Melbourne Marathon in Australia this October. Wherever he races, millions will once again follow the journey of a man whose legacy extends far beyond the stopwatch.
