Wearing purple shorts, a blue and white tie-dyed T-shirt, a bright pink hat, a light blue Salomon hydration pack, fluorescent yellow-rimmed Oakley sunglasses, and a pair of Hoka Speedgoat 5 shoes, Chaiwen Chou was a vibe as she crossed the finish line of Ultra-Trail du Mont-Blanc (UTMB) on Sunday afternoon in Chamonix, France.

Chou, who had also freshened up the pink and purple tint of her hair before the race, stood out among the numerous other dusty and weary runners clad in more traditionally colored trail garb as they took their final strides in the epic 106-mile race around the Mont Blanc massif.

But what was most remarkable about the 41-year-old software developer from New York City was the huge smile on her face and expression of pure joy that emanated from her. When she arrived at the finish line after 45 hours and 15 minutes of running-about 75 minutes before the cutoff-she was beaming ear to ear and greeted with big hugs from her mom, brother, partner, and a good friend who helped crew her on her journey.

While her interest in running started on a bit of a whim a decade ago, her continued passion and progression have led her to run more than 30 trail running races, including the biggest and most celebrated one in the world. On Sunday, she was one of 95 American runners to complete the grueling UTMB course.

"So when I turned 30, I had this typical New Year's resolution, like, I want to get fit, I want to learn how to run," said Chou, who grew up in Massachusetts. "And then I met a friend who ran, and I started running with him and doing group runs. And then we started running trails, and we specifically entered The North Face Endurance Challenge, and that's where I ran my first marathon, and fell in love with trail running and then learned about ultrarunning and this whole world that I never even knew existed."For many recreational ultrarunners from around the world like Chou, UTMB sits at the top of their lifelong bucket list. It means starting at the same time as the elite professional runners on Friday evening in Chamonix, and maneuvering through the same rugged and aesthetic 106-mile loop with a daunting 32,000-feet plus of climbing and descending. It's historic, and the crowds and the energy around it are unparalleled.

It's also a monumental challenge to complete.

Trail Running's Infectious Buzz

Ultra-trail running is having a moment right now-especially since the end of the Covid pandemic-but it probably started a decade ago as the urge to run beyond the marathon gained mainstream traction and destination races around the world started to become desirable goal races for recreational runners.The North Face Endurance Challenge began as a singular 50-mile championship-style trail race near San Francisco in 2006 with a $30,000 prize purse, but it evolved into a multi-distance race weekend (from 10K to 50 miles) aimed at encouraging runners of all abilities to immerse themselves in the sport. After a few successful years of the event in Mill Valley, California, it expanded to several locations across the U.S.-upstate New York, Madison, Wisconsin, and Washington D.C., among others-and around the world.

Although The North Face pulled the plug on the series in late 2019 with a suggestion that it was going to reimagine the event format, nothing ever materialized after the Covid-19 pandemic temporarily disrupted the world-and specifically running events-in 2020. But those events played a big role in introducing runners and non-runners alike to the unique aspects of trail running, and many of those who caught the bug-like Chou-have continued to chase their passion in global events like the UTMB World Series.

Chou and her friends returned to The North Face Endurance Challenge four years in a row and she upped the ante each time, going from the marathon to the 50K and finally to consecutive finishes in the 50-miler. She competed in the 50-mile race in San Francisco in 2017 and 2019 and then started traveling to other races around the U.S. and eventually around the world. By 2020, she had completed the Madeira Island 115K race in Portugal and the Tarawera Ultramarathon 100-miler in New Zealand.

Once Covid subsided, Chou set her sights on trying to get into UTMB, which she did by collecting running stones and finishing seventh at the Grindstone 100 amid torrential rain storms last September in northwest Virginia. Her training for UTMB was interrupted in February when, just a week after she found out she secured an entry into UTMB through the lottery, she broke her ankle. Then once she got to Chamonix a week before the race, she smashed her left  knee on a shakeout run and it swelled up pretty badly.

As such, her UTMB experience was rougher than she had hoped-the 80-degree heat and the 32,000 feet of vertical gain and descent pushed her to her limits-as she had challenges fueling consistently and also got sick several times. But she persevered and reached her primary goal of finishing.

Officially, she was the 1,542nd finisher out of 1,760 runners who completed the full loop. (A total of 1,001 runners started but did not finish.) She did whatever it took and she crossed the finish line.

"So this is the first time I've  been in the Alps, and I'm just blown away by how beautiful it is," she said. "Even though I was in pain pretty much the whole race because the climbing and the elevation gain here are insane compared to the East Coast! But it was just so beautiful everywhere. It's pretty crazy. But you get to be out there all day though, so that's fun."Every Runner Has a Story

Becky Convery only started running four years ago in the middle of the Covid lockdown. What started as short, occasional runs turned into a passion for trail running that was fueled, in part, by doing group runs with the Virginia Happy Trails Running Club.

Like Chou, Convery also qualified for UTMB through the Grindstone 100. The 58-year-old Washington D.C. attorney almost quit that race, but she dug deep to finish. During UTMB, Convery dealt with GI issues from early on in the race and couldn't keep any food down. It was so bad, she almost dropped out at the 51.5-mile aid station in Courmayeur, Italy. But then she thought of Wayne Chang, a running buddy from Virginia, who did just that last year and immediately regretted it. With her friend's experience top of mind as she struggled, Convery persevered and finished in 45:27 with an hour to spare."I wanted to quit at Grindtone last fall. I was miserable and just wanted to go to bed, but he wouldn't let me quit," Convery said. "He's like, 'Look, I quit UTMB and I woke up a couple hours later, and I was like, 'Oh my God, what have I done?' So when it got hard out there (during UTMB), I thought of Wayne, and even though I couldn't keep food down, I said to myself, 'What would Wayne do?' He'll kill me if I quit, so I knew I couldn't quit. So I just kept going."

As much as UTMB gets considerable international notoriety for the livestream and media coverage around the elites-and understandably so, it draws many of the world's best runners-at the heart, UTMB is a personal journey of courage, commitment, and hope for most of the 2,800 runners who toe the starting line.

And really, that's what the entire sport of ultra-trail running is all about and what differentiates it from road racing. For many, it's not about racing at all-competing against other runners or even the clock-it's about challenging yourself and the natural terrain in pursuit of a dream that might seem like it's on the realistic edge of your abilities.

"It's all about digging deep into yourself," Convery said. "With this race, it's so international and there are so many nations represented, it's just an amazing time up there. Even though most people don't speak each other's language, everybody gets it. Everyone is pulling for each other. It's a great environment out there. I'm glad I made it."

Going the Distance

That's always been the case for 67-year-old Mike Smith, a retired resident of Santa Fe, New Mexico, who reached the finish line 15 minutes after Convery. It was Smith's second year in a row finishing UTMB, and because he won his age group at the Canyons 100K in April, he'll likely be back next year.

"The best part about it is always the people," Smith says. "But, oh gosh, chasing the time cutoff at that last aid station, that hike up to the La Flegere ski area, that's always a challenge."Smith relishes in those kinds of ultra-trail challenges. By reaching the finish line in Chamonix, he recorded the 224th 100-mile trail race finish of his career dating back to the mid-1990s. According to an ultrarunning history site, he ranks No. 2 in the world in all-time 100-mile finishes and first among 100-mile trail races. (Last year's UTMB was his 205th finish, which means he completed 18 100-mile ultra-trail races in the interim.

"This is always a spectacular finish," said his wife, Sandra, who wrote a book about what it's like to crew her husband at races. "This is one of the most exciting finish lines there is. The finish lines at smaller races are exciting because there's such a close community of people, but here, there are so many people from around the world, and that's just wonderful."

In all, 2,761 runners started this year's UTMB and 1,760 finished, including 95 U.S. runners who reached the finish line (out of 152 American starters) under the cutoff. Frenchman Vincent Bouillard was the overall winner in 19:54:23 on Saturday afternoon, but 20 hours later there were still about 1,000 runners moving toward the finish line and trying to beat the 46.5-hour cutoff on Sunday afternoon. Among the 95 U.S. finishers, 41 completed the course after the 40-hour mark.

Lamont King, 51, a runner from Roseville, California, has watched and been inspired by runners finishing in the golden hour of the Western States 100 as a fan and as a board member of the race for years. So finishing UTMB on his first try in 45:59-about 30 minutes before the cutoff-was a special moment for him.

"The race was very, very tough. We just don't have that kind of vertical in California where I'm from," said King, who has been trail running for 20 years. "But it's just amazing to be in this scenery in the mountains. It's just fantastic, and it makes up for a little bit of pain. I did have to push a little bit more than I probably would've liked, but I got it done. Coming in with all those people cheering for you in that final finish is almost overwhelming. It's just beautiful."

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.

2. Nevin Can (Turkey) – 1:05:06

3. Selin Can (Turkey) – 1:05:11

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

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.

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.
