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 where he now works 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.

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.

Kenya delivered another commanding display of distance-running excellence at the Antrim Coast Half Marathon, with Isaia Lasoi leading a memorable Kenyan clean sweep of the men's podium in a race packed with world-class performances.

Lasoi emerged victorious after a thrilling battle at the front, crossing the finish line in a superb 58:26 setting a new course record. His winning performance underlined his strength and speed over the half-marathon distance, but he was made to work all the way by fellow Kenyan Daniel Mateiko, who finished just three seconds behind in 58:29 after an electrifying duel for the title.

The contest between the two leaders produced one of the standout moments of the race, with both athletes pushing deep into elite territory as they fought for victory. In the end, Lasoi found just enough to secure the win, while Mateiko's narrow defeat highlighted the remarkable depth and quality of Kenya's leading distance runners.

Vincent Kipkorir completed the Kenyan sweep, taking third place in 1:00:38 to ensure that all three places on the podium belonged to Kenyan athletes. Samwel Chebolei added further Kenyan strength to the results, finishing fourth in 1:01:01, while Amos Langat was also among the leading finishers.

The international field featured several prominent names. Australia's Jimmy Whelan produced a strong run, while Ethiopia's Yismaw Dillu featured among the front group. American marathon star Galen Rupp also delivered a notable performance, clocking 1:01:29 in another competitive outing for the experienced distance runner. Former world-class track and road athlete Edward Cheserek was also among the top finishers.

Lasoi's 58:26 victory, however, was the defining performance of the day. Together with Mateiko and Kipkorir, he gave Kenya a perfect podium and another emphatic reminder of the country's extraordinary strength in elite road running.

The Antrim Coast Half Marathon once again provided a fast, competitive stage for some of the world's finest distance runners, but when the decisive moments arrived, it was Kenya that owned the podium.

One of the most iconic milestones in the history of ultramarathon running is drawing closer, with entries for the historic 100th edition of the Comrades Marathon set to open on Tuesday, 25 August 2026.

The Comrades Marathon Association has officially announced a detailed entry process for the 2027 race, which will unfold in three stages and give runners around the world the opportunity to secure their place in what promises to be one of the most significant editions ever held of The Ultimate Human Race.

The announcement followed the official launch of the 2027 Comrades Marathon on Wednesday, 19 August, when the centenary campaign, “The Greatest Story Ever Run,” was unveiled alongside a special logo created exclusively for the landmark 100th edition.

The launch also revealed several major highlights for the Centenary Race. The historic event will take place on Sunday, 13 June 2027, and will be a Down Run, with 28,000 places available. The entry process will include a ballot, while the race will offer a record R8.919 million in prize money. Organisers have also set an ambitious goal of raising R10 million for the Amabeadibeadi charities, adding an important charitable dimension to the centenary celebrations. One of the defining moments of the launch was the unveiling of the special Centenary mark, created to commemorate this extraordinary milestone in the history of the race.

The entry process begins on 25 August at 10:00 a.m. SAST, when entries open for Green Number runners, Yellow Number runners and Amabeadibeadi charity entrants.

The next phase follows on 2 September at 10:00 a.m. SAST, when entries open for Comrades Marathon Association members. This window will remain open for 72 hours or until the available entry allocation is filled, with places offered on a strictly first-come, first-served basis.

For general entrants, the process will move to a ballot system. General entries open on 9 September at 10:00 a.m. SAST, with runners able to enter the ballot until it closes on 22 September at 4:30 p.m. SAST. The ballot draw is then scheduled to take place on 23 September.

For runners dreaming of becoming part of this historic occasion, the road to Comrades 2027 is now clearly marked. From the opening of entries in August 2026 to race day in June 2027, every deadline will matter.

The Greatest Story Ever Run is preparing for its most historic chapter yet.

American sprint standout Sam Blaskowski is taking steps toward an international future with Poland after uncovering a powerful connection to his family's ancestral homeland.

The 23-year-old sprinter, who has established himself as one of the fastest Americans of his generation with a personal best of 9.89 seconds in the 100 metres, has begun the process of obtaining Polish citizenship with the aim of eventually representing Poland in international competition.

Blaskowski's connection to the country traces back through his great-grandparents, Franciszek and Julian Błaszkowski, who emigrated from Poland to the United States in 1905. Their journey more than a century ago has now opened an unexpected new chapter for their descendant, whose athletic ambitions could soon carry the Błaszkowski name back onto the international stage under Polish colours.

The sprinter has already received support from the Polish Athletics Association as he works through the citizenship and eligibility process. Should his transfer of allegiance be completed, Blaskowski could become a significant addition to Poland's sprint programme.

His credentials certainly make the prospect an exciting one. In addition to his sub-10-second speed over 100 metres, Blaskowski owns a personal best of 19.93 seconds in the 200 metres, demonstrating the kind of versatility that could prove valuable both individually and in Poland's 4x100m relay squad.

For Blaskowski, however, the move is about more than simply changing national colours. It represents an opportunity to reconnect with his family's heritage while pursuing his ambitions at the highest level of the sport.

With his sights set on becoming part of Poland's international sprint team and competing for relay medals, Blaskowski's journey from discovering his Polish roots to potentially representing the country of his ancestors could become one of the most fascinating allegiance stories in world athletics.

A century after Franciszek and Julian Błaszkowski left Poland for America, their family's story may now be coming full circle—this time at full sprint.
