A new review study points toward post-exercise ketone supplementation as a way to improve adaptation and performance. What does the uncertain science mean for endurance athletes?

I heard about athletes supplementing with ketones sometime in the mid-2010s. A company reached out, promising the next big breakthrough in endurance performance from this liquid supplement composed of a molecule naturally produced in the body from the breakdown of free fatty acids. They told me that the top cyclists in the world were already using ketones and that it was destined to take over running, too. They sent a few boxes…and they collected dust in the pantry. It felt like a biohack, and I wasn’t comfortable with it.

Over the years, more studies on ketone ingestion emerged, and I started to get more and more intrigued. Rumors came out that about 70 percent of the cycling peloton used the stuff. But they cost a ton, and it was hard to discern what was actual practice and what was just marketing.

It wasn’t until 2023, though, that I embraced that ketones were here to stay, whether I liked it or not. A 2023 study in the American Journal of Physiology-Endocrine and Metabolism had nine men complete two cycling trials, both with one hour consisting of two minutes at 90 percent of aerobic capacity (moderately hard), followed by two minutes at 50 percent of aerobic capacity (very easy). In both trials, the cyclists consumed a carb-protein drink immediately after exercise and at one, two, and three hours later. Here’s the study intervention: in just one trial, participants ingested 0.29 g/kg ketone monoester immediately after exercise and at one and two hours later.

The ketone trial led to 20 percent higher levels of natural erythropoietin (EPO) in the bloodstream.

For comparison, a 2005 study in the British Journal of Sports Medicine found that the initial exposure to altitude training increased EPO by an average of around 50 percent in swimmers, with large individual variability (returning to baseline after a couple of weeks of altitude training), with lots of variation across studies. Given that our bodies produce EPO to increase red blood cell production, and red blood cells transport oxygen that power endurance performance, the ketone study indicated that we could be seeing a supplement that supercharges adaptation and performance.

Context for Ketones

To be 100 percent honest, I was sad when I saw this study. I love performance physiology, but I don’t want to think about a new biohack. Maybe it’s a sign that I’m getting old when a study on cutting-edge science just makes me tired. Get these research protocols off my lawn!

But I also couldn’t bury my head in the sand (though that would probably increase EPO concentrations via hypoxia). Instead of giving into my old-coach fatigue, maybe I can help publicize the emerging science so fewer athletes have an information disadvantage. My final push was last week when a fantastic review article was published in the American Journal of Physiology-Cell Physiology by Ruben Robberechts and Chiel Poffé. If ketone supplementation has the potential that some think it may, the article could be a key step in the future of exercise physiology.

Before getting to the science, I think it’s important to lay out the stakes. Based on the articles (mixed with a heaping dose of gossip), I can see three different scenarios unfolding over the next 10 years.

One, post-exercise ketones don’t live up to their promise, and this is all a nothingburger. That outcome would please me the most, and we all know that what’s most important in science is my pleasure. If researchers did this type of theoretical analysis on other interventions (i.e. heat training, Vitamin D, lifting, ashwagandha, strides, beta-alanine, doubles, creatine), they could come back with similar findings. We are only talking about a few intervention studies and lots of theory, and future research could have different results. Plus, some critics would already be confident making their judgments as the Supreme Court of Nothingburgerland.

Two, ketones could become a more commonly used supplement with benefits for performance and health (like iron). They are expensive, which isn’t great, but maybe they will help athletes be healthier and faster, with limited side effects. On the flip side, maybe more research indicates tradeoffs that lead to benefit:risk calculations with performance or health. Over email, Dr. Poffé–an author of the review study and a key researcher in this field–says that “studies have shown divergent effects on performance depending on the exercise context and whether you take them before, during or after exercise.” Even if they are beneficial in some contexts, it’s not a simple equation of take ketones = get faster.

The third possibility is that they are banned as an illegal performance enhancer. I have no inside info on whether that’s a possibility, and at first blush, it doesn’t seem likely without some health risks. Dr. Poffé says “I honestly don’t see much of a reason to ban ketones while allowing other ergogenic supplements.”

So, yeah, we’re talking about a wide range of possibilities, which makes sense given the uncertain mechanisms and effects at play. Let’s dig in. (We got even deeper into the nuance on our podcast this week, which you can listen to here.)

Introduction to Ketones

As stated by the review study, ketone bodies “are molecules that are continuously produced from the breakdown of free fatty acids,” primarily in the liver. Ketone body production is upregulated during periods of low carbohydrate availability—that’s why you have heard “ketosis” thrown around for ultrarunners who practice low carbohydrate, high-fat nutrition, aiming to improve fat oxidation and avoid bonking. Ketosis via nutritional interventions comes with way too many downsides for endurance athletes, though, including everything from reduced bone density to diminished high-intensity performance. That makes sense intuitively because low carbohydrate availability is extremely stressful on most body functions, especially the endocrine system.

Ketone esters, enter stage left. Researchers figured out how to create an ester bond between a ketone body precursor and a ketone body (first in 1978 in rats, but not undergoing human testing until 2012). These ketone esters cause a “rapid and transient increase in ketone bodies,” possibly inducing ketosis. It was as if this evolutionary mechanism honed over millions of years now had a dimmer switch. For the chemistry nerds out there, you can probably guess what oral ingestion of an ester is like—not fun. Companies like HVMN honed the taste over time, and now I’d say that ketone esters taste like a robot’s ass. We can only imagine what they tasted like before.

Ketones have mostly been marketed as a before-and-during-exercise supplement, at least in the podcast ads I have heard. Take ketones, burn more fat at higher intensities, win the Tour de France, etc. However, a bunch of studies have shown limited to no acute benefit. For example, a 2017 study in Frontiers of Physiology found that pre-exercise ketone supplementation caused around a two percent performance decrease in 10 male professional cyclists doing a 50-minute time trial.

Perhaps there’s some protocol being used in the cycling peloton that improves acute performance, as the marketing claims indicate. Heck, Tom Evans reportedly took ketone esters on his way to winning Western States, so there must be some benefit for some athletes (or at least neutral impacts), possibly related to perceived effort. Anecdotally, when I tried ketones on a fatigued long run, the lights went out. Thankfully, I had my phone to call the Wuber (when my wife Megan drives to pick me up).

So perhaps it’s something else. Maybe all this ketone hype is because taking them improves recovery and hematological variables, confounding variables that are actually the driving force behind their use (maybe that even explains some of the success stories behind low carb, high fat nutrition approaches. I’d love to see the blood work!).

According to the review, after exercise, circulating ketone bodies are increased. However, any benefits athletes may see from a sustained increase are blunted in advanced athletes practicing good recovery nutrition. Ketone esters “may induce a unique physiological milieu to enhance post-exercise recovery and exercise adaptation as it allows to benefit from the potential beneficial effect of post-exercise ketosis in combination with other nutritional exercise recovery strategies (e.g., carbohydrate-protein recovery drink).” They had me at physiological milieu. Dr. Poffé says that his lab started ketone work in 2016 when “there was already some preliminary data showing that it could help riders during the Tour de France as a recovery aid.”

Mechanisms of Post-Exercise Ketones

I can’t emphasize enough how great this review article is, summarizing extremely uncertain science and studies. Before getting to the EPO mechanisms, let’s briefly touch on a bunch of other considerations. First, ketone bodies may cause epigenetic changes. For example, histone lysine β-hydroxybutylation could increase with ketone body increases, which may “increase transcription of genes involved in the adaptive response to exercise.” Across several different epigenetic mechanisms, it’s possible that ketone bodies could be a signal to the body to adapt to stimuli (which makes sense given their evolutionary role in exercise in energy-limited environments).

Second, ketones could “enhance the restoration of cellular energy status after exercise” while also blunting AMPK phosphorylation, which could enhance recovery due to its role in cellular stress or decrease adaptation due to its role in mitochondrial biogenesis. I love this one because that maybe-good, maybe-bad uncertainty regarding downregulation of AMPK points out just how little is known about the long-term consequences of post-exercise ketones, particularly in conjunction with other impacts.

Third, ketones alter g-receptor signaling, which “mediate cellular responses to a wide variety of external agents.” Fourth, ketones show anti-inflammation and anti-oxidation properties, which seems good at first glance but could theoretically cause long-term reductions in training adaptations since the inflammation response can spur adaptation. Fifth, ketones may influence neurotransmitter concentrations in the brain, which could profoundly impact perceived exertion (and possibly even mental health, though that’s a topic for another day).

The next cohort of potential adaptations are at the cutting edge of science but still theoretical. Ketones could increase muscle glycogen resynthesis, reduce protein degradation and enhance protein synthesis, spur angiogenesis that leads to more capillaries to supply blood to working muscles, induce favorable changes in muscle mitochondria, and improve sleep quality in athletes who are training hard. You can put those variables together with a 2019 study in the Journal of Physiology, where male athletes completed a three-week overload training block with six days a week of two-a-day training sessions, with one group having post-exercise ketones. That study found higher tolerated training load in the ketone group and improved performance. (The study was the subject of a Letter to the Editor disputing some of the conclusions.)

A 2023 study looked at a similar three-week overload block, validating the findings. They had 18 male athletes complete 10 training sessions per week, with one group taking post-exercise and pre-sleep ketones and the other taking a placebo. The ketone group “increased the number of capillary contacts and the capillary-to-fibre perimeter exchange index by 44 percent and 42 percent,” plus “substantially increased vascular endothelial growth factor and endothelial nitric oxide synthase expression both at the protein and at the mRNA level.” And the money finding: EPO concentrations in the ketone group increased by 26 percent. That study was eye-opening for the possible recovery and adaptation benefits of ketones, and it brings us back to the elephant in the room: potential hematological changes from increased EPO production.

Hematological Changes

In 2018, a study in the Diabetes Care journal found increasing levels of EPO after a ketone body infusion. The authors of the 2023 study that started this article cited this study as part of the impetus for their investigation (read their amazing summary here). We’re seeing similar findings in athletes in the 2023 studies, which found 20 percent and 26 percent increases in EPO production in the ketone groups relative to controls. But the science is not there to make a definitive conclusion.

In the title of this article, I promised uncertain science, and now we are deep in it. First, we don’t know how much this EPO change may impact performance. “Currently,” the review says, “it has not been identified if the observed changes in EPO post-exercise are indeed sufficient to induce an improvement in hemoglobin mass and oxygen transport capacity in humans, and whether these effects are additive to stimuli that are frequently used by athletes to increases EPO such as hypoxia.” It’s possible that these changes don’t correspond to performance benefits.

And get a load of this: “The precise physiological mechanism underlying ketone body-induced upregulation of EPO is currently unknown.” However, based on mouse models, the researchers theorize that it relates to H39K acetylation in kidney cells.

Are Ketones the Future?

There are tons of unanswered questions. How do these types of adaptations change over time? The longest study right now is a few weeks.

Do the processes change in female athletes? That’s one of my big concerns in making any recommendations since metabolic processes can vary based on gender. While more research is needed, Dr. Poffé indicates that past studies likely show that the results can be extrapolated to female athletes. “In a recent, unpublished study,” he says, “we observed that some effects are even more pronounced in females.”

How about aging athletes? Athletes of different levels, with different goals and backgrounds? What’s the right dosage and timing? Would the same responses happen at altitude? Should consumption be periodized? With similar studies, would other interventions lead to similar findings? Should ketones be banned altogether?

I don’t know the answers to those questions, and a lot more studies are needed before I make coaching recommendations other than “be careful” and “keep it simple.”

“Similar to most nutritional supplements,” Dr. Poffé says, “the long term effects (e.g. what occurs if you supplement for multiple years) are not known.” When athletes take ketones, he says instead of taking them chronically, to supplement “during periods of limited recovery opportunities,” like training camps. From a performance perspective, he advises to consider ketones when everything else is sorted out around training, nutrition, and recovery. They are “the final step,” not the first one.

In September, after reading the research, I dusted off that old package of ketones and opened up a serving for myself. Then I threw it in the trash because it seemed like a health hazard after all those years. I ordered a new package and started experimenting with them a couple days a week post-exercise. In October, at the Blue Sky Marathon, I closed the final four miles two minutes faster than last year to set a course record.

That probably had nothing to do with ketones, right? I’m no Olympian, but I train hard. And when looking back on the race and why I could finish so fast while feeling so good, I would be burying my head in the sand not to consider one of the only variables that changed.

I’m not sure what the future holds with post-exercise ketone supplementation. Maybe it’s all snake oil and placebo, with some studies that find physiological anomalies without a demonstration that it fundamentally alters performance trajectories, destined to be covering dust in the pantry of exercise physiology history.

Or maybe we’re seeing the dawn of a revolution in endurance training and performance.

 

British middle-distance star Keely Hodgkinson is proving that the impact of an Olympic champion extends far beyond the medals she wins, as her remarkable achievements continue to inspire young girls to believe in their own sporting dreams.

A heartwarming image of a young British girl recreating Hodgkinson’s iconic champion pose, dressed in a replica of her racing kit and proudly draped in the Union Jack, has captured the beautiful connection between sporting heroes and the next generation of athletes. It is a powerful reminder that what begins as admiration for a champion can eventually become the inspiration to follow in her footsteps.

Hodgkinson secured her place among Britain's greatest middle-distance runners at the Paris 2024 Olympic Games, where she won the women's 800 metres gold medal in 1:56.72. The victory marked the culmination of years of determination and perseverance, bringing Olympic glory to a career that had already seen her claim silver at the Tokyo 2020 Olympics and the 2022 World Athletics Championships.

Her triumph in Paris was more than a personal milestone. It was a moment that allowed countless young athletes to see what was possible through dedication, confidence and a willingness to pursue ambitious goals.

For Hodgkinson, the power of inspiration is something she understands personally. As a nine-year-old girl, she watched Dame Jessica Ennis-Hill win heptathlon gold at the London 2012 Olympic Games. That unforgettable performance helped spark her own interest in athletics, setting her on a journey that would eventually lead her to the top of the Olympic podium.

Now, more than a decade later, Hodgkinson has become the very kind of sporting role model who can ignite that same ambition in another young athlete.

The young fan's recreation of her Olympic hero is a touching reflection of how sporting success can influence children long before they take their first competitive steps on the track. Wearing a champion's colours, adopting her winning pose and celebrating her achievements may seem like simple gestures, but they represent something much bigger: the beginning of a dream.

Hodgkinson has also developed a distinctive identity beyond her performances, with her confident race-day style, Union Jack-inspired details and unapologetic personality making her a recognisable figure in British athletics. For many young fans, she represents a modern champion who combines world-class ability with individuality and self-belief.

Her story also highlights the importance of visibility in sport. When young girls see women achieving extraordinary things on the world's biggest stages, they are given tangible examples of what determination and ambition can accomplish. Champions such as Hodgkinson help make athletics more accessible and exciting, encouraging the next generation to lace up their trainers, join a club and discover their own potential.

Of course, not every young admirer will become an Olympic medallist, but the influence of a sporting hero can extend well beyond competition. The confidence to try something new, the discipline to work towards a goal and the courage to keep going after disappointment are lessons that can shape a lifetime.

For Hodgkinson, her legacy will ultimately be measured by more than the gold medals she wins or the records she may break. It will also be reflected in the young athletes who find the courage to chase their ambitions because they watched her succeed.

Just as Ennis-Hill's triumph at London 2012 helped inspire a young Hodgkinson, the British 800m champion is now passing that inspiration forward, showing a new generation that today's dreams can become tomorrow's achievements.

Somewhere among the young fans proudly recreating her winning pose could be a future British champion, an Olympic medallist or even the next athlete to redefine the limits of the 800 metres.

Today, she may be a little girl looking up to her hero. Tomorrow, she could be the champion inspiring millions of others.

At 67, Canadian runner Pete Benson is preparing to take on one of the most extraordinary endurance challenges in marathon running: completing seven marathons across seven continents in just seven days while raising money for a cause that reaches far beyond the finish line.

Hailing from Grand Manan, New Brunswick, Benson is set to participate in the Great World Race, an ambitious event that combines the physical demands of marathon running with a demanding journey around the globe. The challenge will require him to complete seven full marathons, each covering 42.195 kilometres, while travelling between continents on a tightly scheduled itinerary.

The challenge is scheduled to begin on November 15, 2026, with pre-event activities expected to start around November 12. Benson's adventure will begin in Antarctica, where the icy terrain and harsh conditions will provide a formidable introduction to the week ahead.

The opening marathon is scheduled for Wolf's Fang in Antarctica, where Benson will face the unfamiliar and potentially unforgiving conditions of the frozen landscape. Reflecting on the prospect of running through the ice and snow, he admitted that the experience is intimidating.

"That's pretty, pretty scary in itself," he said. "Through the ice and snow."

From Antarctica, Benson will travel to Cape Town, South Africa, for his second marathon on November 16. The journey will then continue to Perth, Australia, on November 17, followed by Singapore on November 18. On November 19, he is scheduled to race in the Algarve, Portugal, before heading to Cartagena, Colombia, on November 20. The challenge will conclude in Miami, United States, on November 21.

The demanding itinerary will leave little time for conventional recovery. After each marathon, Benson will need to travel to the next destination, navigate changing time zones and prepare for another 42.195 kilometres. Managing fatigue, nutrition, hydration and sleep will be essential as he attempts to complete the seven races within a single week.

Benson described the unusual routine that awaits him, highlighting the relentless cycle of running and travelling that defines the challenge.

"We run the race, get back on the bus, back on the plane, head to the next one and away we go around the world," Benson said. "That plane becomes our hotel and restaurant for the week, pretty much."

Beyond the physical demands, Benson recognises that taking part in such an ambitious international adventure comes at a considerable financial cost. He describes running as a personal investment, one that has provided him with valuable experiences and opportunities to discover more about himself.

"It's certainly a want, not a need," he said. "Some people go on river cruises and other things that they spend their money on and I spend my money on running and I've learned a lot from it."

Despite the expense, Benson believes the experience is worth the investment.

"So I think the investment is worth it, but it is extravagant," he said.

However, his motivation extends beyond personal achievement. Benson is also using the challenge to raise money for a nonprofit organisation that funds clean-water projects in countries around the world. The fundraising initiative is voluntary and is not a requirement for participating in the event.

By connecting his running adventure to a cause with a tangible impact on communities, Benson hopes to give every kilometre a greater purpose. His effort demonstrates how an individual sporting challenge can also become an opportunity to support work that improves lives.

"I'm happy that there's a purpose behind every mile that I run," he said.

That purpose adds another dimension to Benson's ambitious undertaking. While the seven marathons will test his physical strength, mental resilience and ability to recover between races, his fundraising mission will allow him to contribute to efforts aimed at improving access to clean water around the world.

As November 15 approaches, Benson is preparing for a demanding week that will take him from the ice and snow of Antarctica to the streets of Miami, with five other destinations in between. Each marathon will bring a new test, requiring careful preparation, determination and the ability to keep moving forward despite accumulating fatigue.

At 67, Benson is setting out to complete an extraordinary endurance challenge while supporting a cause beyond himself. Seven marathons, seven continents and seven days will test his limits, but his journey will carry a purpose that extends far beyond the finish line.

Kenyan twins Caroline and Purity Gitonga delivered outstanding performances at the 2026 Valencia Half Marathon in Spain, with both athletes setting new personal bests in a memorable display of endurance, determination, and sibling excellence.

Caroline led the way, clocking an impressive 1:04:59 to finish sixth in the women's race. The performance marked a significant breakthrough for the talented Kenyan, who improved her previous personal best of 1:06:26 by 1 minute and 27 seconds, underlining her continued progress among the world's leading half-marathon runners.

Her twin sister, Purity, was equally impressive, crossing the finish line in 1:05:56 to secure 11th place. She shaved 1 minute and 35 seconds off her previous personal best of 1:07:31, completing a remarkable day for the sisters as they both reached new milestones in their athletic careers.

Their performances highlighted the strength of Kenya's distance-running tradition while showcasing the individual talent and shared determination that have made the Gitonga twins athletes to watch. Competing on one of the world's fastest half-marathon courses, Caroline and Purity demonstrated their ability to translate hard training into significant improvements on the international stage.

Having a twin sister who understands the demands of elite athletics can provide a unique source of motivation. From the discipline required during training to the challenges of competing against the world's best, the sisters share a journey that extends beyond the finish line. Their latest achievements in Valencia offer another inspiring example of how ambition, perseverance, and mutual encouragement can drive athletes toward new heights.

For Caroline, finishing sixth in 1:04:59 represents another important step in her development, while Purity's 1:05:56 performance confirms her own impressive progress. Although they finished several places apart, their achievements tell the same powerful story: two athletes pushing their limits and continuing to improve against a highly competitive international field.

Valencia once again provided a stage for exceptional distance-running performances, and the Gitonga twins made the most of the opportunity. Their personal bests are not only a testament to their hard work but also an encouraging sign of what they could accomplish as they continue to gain experience and pursue even greater ambitions.

Two sisters, two personal bests, and one unforgettable day on the roads of Valencia. Caroline and Purity Gitonga have given Kenyan athletics another reason to celebrate, and their latest performances will undoubtedly strengthen interest in what the talented twins can achieve in the seasons ahead.

Australian endurance athlete Mick Marshall has achieved an extraordinary milestone at the 2026 Marine Corps Marathon in Washington, D.C., setting a world record for the fastest marathon completed on crutches after crossing the finish line in an incredible 5:35:50.

Representing Altra as an elite athlete, Marshall demonstrated remarkable determination and perseverance throughout the 26.2-mile (42.195-kilometre) race, turning one of the world's most celebrated marathon events into a stage for an inspiring display of human resilience.

Completing a marathon is a demanding physical challenge for any athlete, requiring months of preparation, mental strength and the ability to push through fatigue. Covering the same distance on crutches presents a different set of challenges, placing considerable demands on the upper body, coordination and endurance. Marshall's achievement highlights the dedication required to overcome obstacles and pursue goals that many might consider beyond reach.

The Marine Corps Marathon, renowned for its patriotic atmosphere, enthusiastic spectators and scenic course through the nation's capital, provided a memorable setting for the record-breaking performance. As thousands of runners pursued their own finish-line goals, Marshall carved out a special place in the event's history with his remarkable effort.

Beyond the record itself, Marshall's achievement carries a message that resonates far beyond the running community. Every movement toward the finish line required determination, patience and an unwavering commitment to the challenge before him. His performance is a reminder that greatness is not measured solely by how quickly someone reaches a destination, but also by the courage it takes to pursue a goal despite the difficulties along the way. For aspiring athletes and anyone facing personal challenges, his accomplishment offers a powerful lesson in perseverance, self-belief and the importance of refusing to give up when the journey becomes difficult.

His performance also serves as a reminder that marathon running is about far more than finishing times and podium positions. It is a test of courage, commitment and the willingness to redefine personal limits. Marshall's accomplishment demonstrates that the spirit of distance running extends beyond conventional expectations, inspiring athletes and spectators alike to reconsider what is possible through determination and hard work.

Marshall's remarkable run also reinforces the inclusive spirit of distance running, where the finish line belongs to everyone willing to take on the challenge. Whether competing for a championship, chasing a personal best or simply striving to complete the distance, every runner has a story worth celebrating. By setting a world record on crutches at one of America's prominent marathon events, Marshall has added an unforgettable chapter to that story, encouraging others to look beyond perceived limitations and pursue their ambitions with renewed confidence.

For Marshall, the 5:35:50 finish represents more than a time on the clock. It marks an extraordinary personal achievement and a moment that celebrates perseverance, resilience and the determination to keep moving forward. His performance has brought renewed attention to the remarkable possibilities within endurance sport and the many different ways athletes can challenge expectations.

Marshall's achievement at the Marine Corps Marathon stands as a powerful testament to the human spirit, demonstrating that success is not always about having the easiest path, but about finding the strength to keep going. His 5:35:50 performance is a reminder that the finish line can represent much more than the completion of a race: it can symbolise courage, possibility and the extraordinary things people can accomplish when they refuse to give up.

The 23rd edition of the Standard Chartered Nairobi Marathon delivered a spectacular celebration of endurance, determination and competitive excellence on Sunday, October 25, 2026, as Abraham Kiptum and Mercy Kandie Rotich claimed the men's and women's 42km titles in a memorable showcase of Kenyan road-running talent.

With thousands of runners taking to Nairobi's Southern Bypass, the full marathon provided a compelling test of physical strength, tactical discipline and mental resilience. For the elite athletes at the front, every kilometre presented an opportunity to gain an advantage, while the demanding distance required unwavering concentration from the starting gun to the finish line at Uhuru Gardens.

In the men's race, Kiptum produced an impressive performance to secure victory in 2:10:35, narrowly missing the course record by just 23 seconds. The 37-year-old Kenyan demonstrated his experience and endurance throughout the contest, ultimately establishing himself as the strongest performer over the 42.195-kilometre distance.

Kiptum's victory was particularly significant given his recent return to competitive marathon running. The athlete from Kapsabet had continued rebuilding his career and arrived in Nairobi following victory at the CRDB International Marathon in Dar es Salaam, Tanzania, in August. His latest triumph provided another encouraging chapter in his return to the forefront of distance running.

The men's contest produced an exceptionally close battle for the remaining podium positions. Fellow Kenyan Amos Kipkemoi Cheruiyot finished second in 2:10:37, just two seconds behind the champion, while Mark Kibiwott secured third place in 2:11:05.

Dismas Kiplimo finished fourth in 2:11:15, followed by Henry Kiprono Togom, who completed the top five in 2:11:55. The depth of the leading performances underlined the quality of competition on a morning when the front-runners pushed each other towards impressive finishing times.

Kiptum's performance also highlighted the importance of consistency and preparation in marathon running. Having invested months in training, the experienced Kenyan delivered when it mattered most, navigating the course with the composure required to emerge victorious against a competitive field.

The women's 42km race was equally captivating, with Mercy Kandie Rotich claiming the championship in 2:31:25 after a determined performance over the challenging distance.

Rotich demonstrated resilience and composure as the race unfolded, maintaining her challenge through the later stages before securing the victory. Her performance earned her a place among the latest champions of one of Kenya's prominent annual road-running events.

The battle for the women's title was decided by the narrowest of margins. Peris Jerono finished second in 2:31:27, only two seconds behind Rotich, while Ruth Wakabu completed the podium in 2:31:36. The three leading women finished within just 11 seconds of one another, providing a dramatic conclusion to the contest.

Shyline Jepkorir placed fourth in 2:34:55, while Dorothy Kipkilach finished fifth in 2:36:38, rounding out the leading performers in the women's division.

The narrow margins between the leading athletes reflected the unpredictable nature of marathon racing, where pacing, endurance and the ability to respond under pressure can determine the outcome after more than 42 kilometres of competition.

Beyond the podium battles, the full marathon represented a celebration of the determination that defines long-distance running. Every athlete who took on the distance faced the challenge of managing energy, overcoming fatigue and maintaining the mental strength necessary to reach the finish line.

The Southern Bypass provided the setting for these performances, with the runners navigating the Nairobi course before completing their challenge at Uhuru Gardens. The event brought together elite competitors and recreational athletes, united by the ambition to test their limits over the classic marathon distance.

The 2026 edition once again demonstrated the enduring appeal of road racing in Kenya, a country internationally recognised for producing exceptional distance runners. It also offered a platform for athletes to pursue personal ambitions, compete for prestigious honours and showcase the depth of talent within Kenyan athletics.

For Kiptum and Rotich, however, the day belonged to the pursuit of victory. Their respective performances secured them the coveted men's and women's marathon crowns, while the fiercely contested podium finishes ensured that the 42km races delivered the drama and excitement expected of a major road-running championship.

As the 23rd Standard Chartered Nairobi Marathon concluded, the achievements of the two champions stood out as the defining moments of the full-marathon competition, celebrating not only speed and endurance but also the preparation, perseverance and competitive spirit required to conquer 42.195 kilometres.
