Kieran Abbotts is a PhD student at the University of Oregon, studying human physiology. He earned his master's degree in Metabolism and Exercise Physiology at Colorado State University. The lab that he works at now studies exercise and environment and stressors on physiology. In other words, he's an expert on how the chemicals in the body work during exercise, and what happens when things get out of whack. 

"Essentially, there are two kinds of training. There's functional overreaching, which means you stress the body with hard workouts and long runs. Then you provide adequate time to recover, and you induce adaptations," Abbotts said. This kind of training is ideal-your body is getting stronger. "You want to be functionally overreaching as an elite athlete-so that you're making progress and becoming a better runner, but also giving yourself adequate recovery." 

And then there's non-functional overreaching, which can feel the same to many athletes, but it's very different. 

"With non-functional overreaching you're essentially doing the same thing-big workouts, stressing the body-but not giving yourself enough time to recover. And so you start doing damage." That damage might take a long time to show itself, Abbots said, but it eventually will. 

This might be the most important thing to know about being an athlete at any level. Non-functional overreaching is exactly the same as very healthy training, except without enough rest. And rest is different for everyone, which makes it exceptionally easy to slip from functional overreaching into damaging non-functional overreaching without realizing it. Without adequate rest, the body begins to break down instead of build stronger. 

Stress Is Stress

Professional ultrarunner Cat Bradley, 31, living in Hawaii, has experienced fatigue and burnout in various forms, including just after she won Western States in 2017. 

Winning a big race is great, but it also means all eyes are on you-the pressure is high to stay on top. "After winning Western States, I took a month off, but I was still running at a high level. And for lack of a better term, I felt like I had a gun to my back," Bradley said. "I wanted Western States so badly, and after I won, so many things happened and I never shook that gun-to-the-back feeling. After a while, it led to burnout. I had to take a mental break." 

For many athletes, finding success can be the stress that makes non-functional overreaching feel necessary. How can you take an extended break when you're winning and signing new sponsor contracts? 

A second version of burnout for Bradley came when she went through an especially stressful situation outside of running. She was dealing with such extreme daily emotional stress in her personal life that everything else was affected, including running and training. When the body is enduring stress, it doesn't know (or care) what the cause is. We can't put our life into silos. If there's stress in one's life, everything else needs to be adjusted. It doesn't matter if that stress is "just work" or illness, or relationships. 

When you're overtraining, or chronically overstressed, your body is creating higher levels of "catecholamines" hormones released by your adrenal glands during times of stress like epinephrine, norepinephrine, or adrenaline. "Having those chronically high levels of overstimulation and not enough recovery, you wind up with a desensitization," Abbotts said. "Overstimulation also causes decreased levels of plasma cortisol. Cortisol is the stress hormone, and it plays a very important role in your physiology." 

When you're exercising or stressing the body, cortisol will go up, to help the body deal with the stress. But if you're constantly requiring lots of cortisol, your body will eventually down-regulate. It will adapt and then you'll have low levels of cortisol. This means trouble dealing with physical and mental stress. 

In February, Bradley experienced her most recent version of burnout, and it happened mid-race. Bradley was running the Tarawera 100-miler in New Zealand. Besides training for such a big race, she was also working full-time and planning and preparing for her wedding, which was just days after the race. On top of everything, travel to the event was incredibly stressful. 

"I was in fourth place, I could see third, and at mile 85, I passed out and hit my head on a rock," Bradley said. "We can talk about the reasons that I fainted, but I really think my brain just shut down-it was too much." 

For Bradley, reaching burnout has a lot more to do with outside stressors than the actual running. But now she's aware of that-she continues to work on not reaching the gun-to-the-back feeling. The need to please others. The fear of losing fitness in order to take care of her body. It's an ongoing process, but an important one. 

Overdoing Is the American Way

Professional ultrarunner Sally McRae said, based on her observations, Americans are really bad at taking time off. "I've traveled the world and Americans are really bad at resting," she said. "It's part of our work system. You go anywhere in Europe and everyone takes a month-long holiday. You have a kid and you take a year off. We're not conditioned like that in America. It's like you get one week and then after you work a decade, you get two weeks of vacation." 

For McRae, avoiding burnout and overtraining has a lot to do with creating a life that's sustainable. She started working when she was 15-years-old, so she realized earlier than most that life couldn't just be working as hard as possible to count down to retirement. 

"Perspective is massive when it comes to burnout. My goal every year is to find the wonder and the beauty and the joy in what I do. Because it's my job, but it's also my life," McRae said. "And I really believe we're supposed to rest-it should be a normal part of our life. Whether that's taking a vacation or taking an off-season. I take a two-month offseason and I have for a long time." 

One of the most important parts about rest and not overstressing the body is that everyone is different. An overstressed body can lead to hormonal imbalances, which in turn affects everything. 

"When you're overtraining, you tend to get mood changes and have trouble sleeping," Abbotts said. "Two of the big things that stand out are you're exhausted but you can't sleep. And the other is irritability-mood swings, and depression." When you get to the point that you've overstressed your body for so long that the chemicals are changing, pretty much everything starts falling apart.

And even though everyone is different, you'd never know that from looking at social media. "I know social media makes it seem like ultrarunners are running 40 miles a day, doing a 100-mile race every other weekend," McRae said. "And that's insane. You've got to be in touch with yourself. It's very different to wake up and feel sore or tired, but if you wake up and feel like you have no joy in the thing you're doing, you need a real break from it."

How Can the Running Community Do Better?

Elite ultrarunner and running coach Sandi Nypaver wants runners to get more in touch with how they're feeling and less concerned about numbers or what anyone else is doing. 

"I have to have honest talks with people I'm coaching. I need them to feel like they can tell me how they feel, because sometimes they think they have to stick to the training plan for the week no matter what," she said. "But the plan is never set in stone. It's meant to be adjusted based on how you're feeling. Some weeks we might feel great and not need to change anything, while other weeks we might have to totally crash the plan and do something else." 

It's easy to judge ourselves against everyone else, especially when results and reactions are so public and available. 

"It's easy to say, 'if that person only took three days off after a big race, and now they're already back to training, that must be what you're supposed to do,'" she said. "But even at the highest level, training is different for everyone. Resting is different for everyone." 

"Something that's really, really hard for many runners to understand is that once you're not sore anymore, that you're still not recovered," Nypaver said. "A lot of research says that things are still going on in your body for up to four weeks after, for certain races, depending on the distance." 

Sometimes it's difficult to be aware of subtle signs when the soreness is gone. "Convincing people that they need to chill out for a while, even past the soreness, can be really difficult." But after a huge effort, and before the next, people rarely end up saying things like, "I really wish I hadn't rested so thoroughly." Part of it is actually having a recovery plan. Putting rest days on the calendar, focusing on foam rolling and mobility on days that you're not "doing." 

"And, actually just relaxing. Taking it easy. It's not just a running model, we live in a culture where we're always being asked to do more," Nypaver said. "I wish instead of always thinking about doing more, we'd focus on how we want to be more. A lot of us want to be more relaxed and less stressed and happier and enjoy our lives. We need to put our attention on that instead of trying to do so much. It's something I struggle with all the time."

We don't get validation for resting, relaxing, and being present because there's no tangible thing to show for it. There's no "be really calm often" challenge on Strava. But the bigger rewards are great. You just have to trade in immediate dopamine hits for a much more balanced, happier life. 

Simple, right?

"One thing I'm doing, and asking my athletes to do, is to write down your intentions," Nypaver said. "One of my intentions is to chill out more this summer and enjoy it. I grew up thinking it's all about running, and I have to go all-in on running. But having other outlets, other things that I like to do, is so important."  

When you've reached burnout-an extended period of non-functional overreaching, prolonged rest is the only way to let the body fix itself. 

"Once you are overtrained, you need to stop training," Abbotts said. "It's just kind of the bottom line. Maybe some people can get away with greatly reducing their training load, but most of the time you need to stop. You need an extended amount of time off." 

There's nothing glamorous about rest. There's no prize money in relaxing. But it's the absolute key ingredient in extended performance, and in a much healthier, happier life. 

At 60, retired Newcastle teacher Jon Strong is preparing to complete a marathon challenge 12 years in the making — and there is just one letter left to tick off.

Strong has already completed 25 marathons, with each race beginning with a different letter of the alphabet. Now, only J remains.

The final chapter will be written at the Jersey Marathon on October 4, where Strong will line up for the 26th and final race of his remarkable A-to-Z marathon project, which he began in 2014.

For Strong, however, completing the alphabet has been about more than simply finding 26 races. His commitment to environmentalism means he does not fly, making travel to certain marathons considerably more complicated.

That was precisely why the letter J remained unfinished for so long.

The Jersey Marathon takes place on a Sunday, and for years the ferry schedule made the trip difficult to combine with his teaching commitments. Getting back in time for school on Monday morning was simply not possible.

That changed when Strong retired this summer after an impressive 28-year career teaching French, German and Spanish at Dame Allan’s Schools in Newcastle, where he most recently served as Head of Modern Languages.

With his teaching career now behind him, the final piece of the puzzle could finally fall into place.

His alphabet marathon journey has taken him to races across Europe, including the Venice Marathon, Rotterdam Marathon, Germany’s X-ray Marathon and Spain’s Quijote Marathon, named after the legendary character Don Quixote.

Many of those races have been completed in under three hours and 30 minutes, while Strong’s marathon personal best stands at an impressive 2:58.

There is also one unusual ritual that has accompanied him throughout the journey: beetroot juice.

Strong drinks it three hours before every marathon — a routine he has followed for so long that he jokes he would not dare stop now.

After 25 marathons, countless training miles and years of travelling by ferry rather than plane, the finish line in Jersey will represent far more than the end of another 26.2-mile race.

It will complete an extraordinary 12-year quest to run a marathon for every letter of the alphabet.

On October 4, the long-awaited J will finally be ticked off.

One alphabet. Twenty-six marathons. Twelve years. One final letter.

Men's road running is moving into extraordinary territory, and two athletes are increasingly at the heart of its breathtaking evolution: Yomif Kejelcha of Ethiopia and Sabastian Sawe of Kenya.

The pair represent the remarkable depth of modern East African distance running, but they are also doing something even more significant: pushing the boundaries of marathon and half-marathon performance to levels that once seemed almost unimaginable. Through their exceptional speed, endurance and ability to perform at the highest level, Kejelcha and Sawe are helping to redefine what is possible on the roads.

Sawe has established himself as one of the most formidable marathon runners in the world. His astonishing 1:59:30 marathon performance at TCS London Marathon on April 26, 2026, marked as a world record, African record and Kenyan record, demonstrated the extraordinary level the marathon has now reached. It also underlined his position at the very top of the men's marathon world rankings.

Kejelcha has been equally sensational, although his journey has highlighted a different kind of versatility. The Ethiopian, whose background includes world-class performances on the track and across shorter road distances, ran 1:59:41 for the marathon debut also at the TCS London Marathon on April 26, 2026, a performance marked as a national record. Just four months later, he delivered another stunning display by clocking 56:51 for the half marathon at the Argentina's capital, Buenos Aires on August 23, 2026, with the performance marked as a pending world record, African record and Ethiopian national record.

That combination of performances illustrates just how exceptional this new generation has become. Kejelcha's ability to threaten the absolute limits over the half marathon while also producing a sub-two-hour marathon performance speaks to his extraordinary range. Sawe, meanwhile, has continued to establish himself as a dominant force over the classic 42.195km distance, combining remarkable efficiency with the strength and speed required to compete at the very highest level.

The two stars are now preparing to take their talents to different stages of the road-running calendar. Kejelcha's next focus is the Valencia Marathon on December 6, where he will once again turn his attention to the marathon distance and look to build on his remarkable breakthrough over 42.195km. Sawe, meanwhile, is set to race the BMW Berlin Marathon on September 27, giving the Kenyan another major opportunity to showcase his extraordinary marathon strength on one of the world's fastest and most prestigious courses.

Those upcoming races add another fascinating dimension to their respective journeys. While Kejelcha heads to Valencia carrying exceptional speed and versatility into another marathon challenge, Sawe will arrive in Berlin with his sights firmly fixed on maintaining his dominance at the highest level of the sport.

What makes their rise particularly exciting is the wider message it sends to athletics. The marathon is no longer progressing only through small margins. The standards at the top are being pushed relentlessly forward, and performances that once appeared impossible are becoming increasingly realistic.

The official sub-two-hour marathon remains one of athletics' ultimate frontiers. Achieving it under standard race conditions would represent one of the greatest endurance breakthroughs in sporting history. Yet with athletes such as Sawe already breaking the two-hour barrier and Kejelcha running only seconds above it while also producing unprecedented half-marathon speed, that frontier appears closer than ever.

Their careers are different, and their strengths are not identical. Sawe has rapidly become a dominant marathon specialist, while Kejelcha brings exceptional versatility from the track to the roads and across multiple distances. But together, they symbolize the relentless progression of men's road running.

Yomif Kejelcha and Sabastian Sawe are not merely among the fastest men of their generation. They are helping to drive the sport toward a future that once seemed unthinkable. With Valencia and Berlin now on their horizons, the next chapter of this remarkable road-running revolution is already waiting to be written.

Jamaica’s Oblique Seville delivered another sensational statement at the Silesia Wanda Diamond League, storming to victory in a breathtaking men’s 100 metres and setting a new meeting record of 9.83 seconds that made sprinting history in Chorzów, Poland.

In one of the deepest and most extraordinary sprint races ever witnessed, Seville powered clear of a world-class field to take the win, with Kenneth Bednarek of the United States finishing second in 9.87 and fellow American Christian Coleman completing the podium in 9.93.

But Seville’s meeting-record victory was only one part of the remarkable story. For the first time in history, all nine athletes in a single men's 100m race broke the 10-second barrier, producing an unprecedented display of sprinting depth.

The historic race also marked only the second time that every athlete in a men's 100m final had broken 10 seconds, following the eight-man final at the Paris 2024 Olympic Games. In Silesia, however, the achievement went even further, with an entire nine-man field dipping below the iconic barrier.

Nigeria’s Kayinsola Ajayi produced another impressive performance to finish fourth in 9.94, while South Africa’s Gift Leotlela followed in fifth with 9.95. Canada’s Olympic champion Andre De Grasse clocked 9.96 in sixth, with South African star Akani Simbine recording the same time in seventh.

American Ronnie Baker added another sub-10-second performance with 9.97 for eighth place, while Cameroon’s Emmanuel Eseme ensured the historic sweep was complete by running 9.99 in ninth.

Men's 100m Results – Silesia Wanda Diamond League

1. Oblique Seville (Jamaica) — 9.83 Meeting Record

2. Kenneth Bednarek (United States) — 9.87

3. Christian Coleman (United States) — 9.93

4. Kayinsola Ajayi (Nigeria) — 9.94

5. Gift Leotlela (South Africa) — 9.95

6. Andre De Grasse (Canada) — 9.96

7. Akani Simbine (South Africa) — 9.96

8. Ronnie Baker (United States) — 9.97

9. Emmanuel Eseme (Cameroon) — 9.99

For Seville, the victory was another emphatic demonstration of his exceptional form and his ability to rise to the occasion against the strongest opposition. His 9.83 not only secured the Diamond League win but also lowered the Silesia meeting record, putting an exclamation mark on a performance of the highest quality.

Nine men went under 10 seconds. Seville went under 9.84. On an unforgettable day in Silesia, the Jamaican stood tallest in a race that pushed the boundaries of what men's sprinting has ever seen.

Ethiopia’s Fotyеn Tesfay Haylu delivered one of the most remarkable women’s half-marathon performances ever seen on American soil on Sunday, powering to a commanding victory at the 2026 Buenos Aires Half Marathon in Argentina in 1:03:57.

Running with exceptional confidence and strength, Tesfay took control of the race and produced a superb solo performance to rewrite the event record. Her breathtaking run also carried historic significance, as she became the first woman to break the 64-minute barrier for the half marathon in the Americas, producing what is being celebrated as the fastest women’s half-marathon performance ever recorded on the continent.

The Ethiopian star was in a class of her own, crossing the finish line more than a minute clear of Turkey’s Nevin Can, who finished second in 1:05:06. Another Turkish athlete, Selin Can, completed the podium in third place with 1:05:11, as the leading trio all produced strong performances on the fast streets of Buenos Aires.

Kenya also featured prominently in the top positions, with Irene Jepchumba Kimais taking fourth in 1:06:04, followed by Sheila Chepkirui in fifth with 1:06:13. Magaret Akidor Ngathike finished sixth in 1:06:46, while fellow Kenyan Deborah Samum claimed seventh place in 1:08:32.

Brazil’s Nubia de Oliveira Silva was eighth in 1:11:13, while Argentina’s Sofia Luna and Dahyana Juarez rounded out the top 10 with times of 1:11:21 and 1:11:28, respectively.

Top 10 Women – 2026 Buenos Aires Half Marathon

1. Fotyеn Tesfay Haylu (Ethiopia) – 1:03:57

2. Nevin Can (Turkey) – 1:05:06

3. Selin Can (Turkey) – 1:05:11

4. Irene Jepchumba Kimais (Kenya) – 1:06:04

5. Sheila Chepkirui (Kenya) – 1:06:13

6. Magaret Akidor Ngathike (Kenya) – 1:06:46

7. Deborah Samum (Kenya) – 1:08:32

8. Nubia de Oliveira Silva (Brazil) – 1:11:13

9. Sofia Luna (Argentina) – 1:11:21

10. Dahyana Juarez (Argentina) – 1:11:28

For Tesfay, it was far more than a race victory. Her 1:03:57 performance was a statement of extraordinary quality, combining speed, endurance and remarkable solo running to produce a landmark result in Buenos Aires. In a race that will be remembered for years to come, the Ethiopian did not simply win—she redefined what was thought possible for women’s half-marathon running in the Americas.

Ethiopia’s Yomif Kejelcha produced one of the most extraordinary performances in road racing history on the streets of Buenos Aires, Argentina, reclaiming the half marathon world record with a sensational 56:51 performance at the 2026 Buenos Aires Half Marathon.

The former world record-holder delivered a breathtaking exhibition of speed and endurance to take 29 seconds off the previous pending mark of 57:20, set by Uganda’s Jacob Kiplimo and takes a huge chunk from his own former official world record. Kejelcha's new performance is pending the standard ratification procedures, but if officially ratified, it will return the world record to the Ethiopian star and mark another remarkable chapter in the evolution of the event. 

Kejelcha's achievement is particularly significant because the 57-minute barrier had already been broken before. Jacob Kiplimo had previously run under 57 minutes, clocking 56:42 that was not ratified demonstrating that the once-unthinkable barrier was possible. Kejelcha, however, has become the second man to run under 57-minute barrier who now returns to the top of the all-time rankings with another historic performance in Buenos Aires.

The Ethiopian's race was remarkable not only for the final time but also for the way he built his performance. He covered the opening five kilometres in 13:44 before reaching 10km in 27:18. Rather than slowing, Kejelcha accelerated through the middle stages, passing 15km in 40:39 and 20km in 54:02 as he continued to push the limits of elite road racing.

By the time he reached the finish line, Kejelcha had completed the race at an extraordinary average pace of approximately 2:42 per kilometre, producing one of the most astonishing sustained efforts ever witnessed in distance running. His stunning run sent a powerful message to the athletics world and further strengthened his status as one of the most formidable distance runners of his generation.

Behind the record-breaking champion, Ethiopia completed a dominant clean sweep of the men's podium. Tadese Worku Gebresilase claimed second place in 59:18, while Bereket Nega Batebo secured third in 1:00:17, giving Ethiopia a memorable one-two-three finish in the Argentine capital.

Kenya’s Jonathan Kipkoech Kamosong finished fourth in 1:00:20, followed by compatriot Simon Maywa in fifth with 1:00:55. Argentina’s Ignacio Erario gave the home supporters plenty to celebrate with an impressive sixth-place finish in 1:00:57, breaking the one-hour barrier in front of an enthusiastic local crowd.

Dillon Kipyeko of Kenya finished seventh in 1:01:07, with Robert Kiprop Koech eighth in 1:02:01. Mexico’s Julio Ortiz Ponce took ninth place in 1:03:17, while Colombia’s Jimmy Gómez completed the top 10 in 1:03:34.

The Buenos Aires Half Marathon will now take its place in the history books as the scene of a truly extraordinary breakthrough. For Kejelcha, this was more than just another victory. It was a spectacular return to the top, reclaiming a world record he had previously held and once again rewriting the limits of the half marathon.

The 56:51 performance remains pending ratification, but Yomif Kejelcha's run has already delivered one of the defining moments in the history of road racing.
