The American ultrarunner credits patience and reduced carbohydrate intake to helping her smash the women’s course record in the Spartathlon, the iconic 153-mile race from Athens to Sparta

Camille Herron continues up to her usual record-breaking ways, smashing the women’s record at the 40th edition of the daunting Spartathlon ultra-distance running event in Greece on October 2. 

Herron, a 41-year-old Lululemon-sponsored runner from Warr Acres, Oklahoma, covered the 153-mile course in 22 hours, 35 minutes and 30 seconds. She shaved more than two hours off the previous record and became the first woman to finish the course in under 24 hours in the 40-year history of the race. 

Spartathlon was created in 1983 to send runners on a journey following the ancient route of Pheidippides, a courier who ran the distance between Athens and Sparta to seek military aid during a battle against the Persians in 490 B.C.. The modern-day race route includes flat roads and mountainous trails with more than 10,000 feet of elevation gain.

Incredibly, Herron averaged 8:55 mile pace, with her fastest mile clocking in at 6:28 (for the seventh mile).

“Wow, it was so much fun because we were running in the footsteps of Phidippides,” Herron says. “The whole time I was running, I was just trying to imagine what he did running on those ancient roads and paths. It’s a little different nowadays having cars and like all these things we have to dodge along the way. But it was incredible. I just loved the whole day because I love both road running and trail running and the course had big sections of each. To have a race that combined all of that, the process in my mind was all about a journey to a destination.”

Greek runner Fotis Zisimopoulos was the overall winner in 19:55:09, a new course record that broke the longstanding mark of 20:25:00 by ultrarunning legend Yiannis Kouros in 1984. Herron finished third overall behind Zisimopoulos and Norway’s Simen Holvik (22:35:31) and shattered the women’s record of 24:48:18 set by Poland’s Patrycja Bereznowska in 2018.

The Spartathlon course starts with a fast urban road section between Athens and Corinth—where dodging vehicles, traffic and pedestrians is necessary—before transitioning onto trails and meandering through vineyards and orchards before eventually going into the Geraneia Mountains. The final section of the course consists of downhill and flat road sections that lead to Sparta.

As she’s known to do, Herron started fast. But she was surprised to have five other women running seven-minute mile pace alongside her. She made a judgment call to slow down a bit, knowing she had a lot of running ahead of her and needed to save her legs.

“In my mind I’m thinking, ‘This is way too fast,’” Herron says. “I was worried we weren’t going to have our legs under us to hit the mountain section. So I ended up just backing off and let all of these women go. They were just hammering it. I was like, ‘Whoa, this is crazy!’ But at the same time, I was inspired by the other women in the race that they had the courage and the strength to go for it. I was like, ‘Hey, you go girl.’”

Finland’s Noora Honkala and Satu Lipiäinen were at the front, followed by Hungary’s Szvetlana Zétényi, Switzerland’s Stine Rex and Germany’s Sarah Mangler. They all wound up building 10- to 30-minute gaps on Herron. But when they entered the trail section with significant climbing, Herron tapped into her uphill abilities and started closing the deficits to the other women. Once back on the roads, she snapped back into her quintessential quick stride turnover and quickly made up the 12-minute gap to pass Lipiäinen, the second-place woman. 

Out front, Honkala ran fast and pushed the pace the whole day. When she entered the mountain phase of the race, she had a 26-minute gap on Herron. But Herron’s relatively strong trail and downhill running abilities paid huge dividends, and with 20 more miles to go, she caught and passed Honkala. Herron surged the rest of the way, ultimately building a gap of more than 50 minutes on Honkala (23:23:03). Lipiäinen finished third (23:48:34), followed by Zétényi (27:57:49) and Rex (28:18:35) in what was the most competitive women’s race in the history of the event.

Herron continues to improve with age, especially in longer events. In February,  she set multiple masters world records and U.S. records at the Raven 24-Hour race in South Carolina, running 150.43K (93.47 miles) in 12 hours, and then crossing the 100-mile mark in 12:52:50. 

Then in March, Herron set a new women’s world record after logging 435.336K (or 270.505 miles) in 48 hours at the Sri Chinmoy 48-Hour Festival in Canberra, Australia. That mark not only broke the existing women’s 48-hour world record of 411.458K (255.668 miles) set by U.K. runner Joasia Zakrzewski, but it also surpassed the all-time American record of 421.939K (262.181 miles) previously set by Olivier LeBlond in 2017. In surpassing LeBlond’s mark, Herron became the first female runner ever to hold an overall American record at any distance.

Herron credits her recent testing with Trent Stellingwerff, the Director of Innovation and Research at the Canadian Sports Institute, for helping discover that Herron has a high VO2 max and produces a naturally high fat oxidation rate when she’s running long distances. Herron underwent that testing as part of Lululemon’s FURTHER initiative, which is backing scientific studies for women as a means to better understand women’s sports performance.

Working with her dietician, Herron used that knowledge to cut back on her carbohydrate intake during Spartathlon to less than 50 grams per hour, down from the 60 to 75 grams per hour that she had been consuming in events earlier this year and in prior years.

Her main source of fueling? Aside from taking a gel every hour, she consumed sections of honey and salt sandwiches that her husband and coach, Conor Holt, served her at aid stations.

“Those changes were life-changing,” Herron says. “I mean, you hear about athletes in marathons and shorter races that are trying to increase carbohydrate intake. But we learned my body is naturally wired for fat oxidation, so I ended up backing off my carbohydrate intake and it made me feel better. It just paid off later in the race. I wasn’t having the gut problems I’ve had in the past, so I was able to just run like a ‘Steady Freddie’ and perform better. It just shows the longer I go, the stronger I am, and I’m able to really show what my natural physiology is capable of beyond a hundred miles.” 

Colt said Herron’s training also played a key role in her success. She put in significant mileage during stints in Oregon, Colorado, and Oklahoma during the summer and then arrived in Greece a week before the race so she could run the course over several days.

“We did our homework and we did the training and she was ready,” Colt says. “She’s got a few more good, good ones in her, I think.” 

Herron dedicated her performance to German ultrarunner and friend Nele Alder-Baerens, who is suffering from Amyotrophic lateral sclerosis (ALS) and can no longer compete. She said she’s inspired by women like Alder-Baerens, who holds the world record for running 85.492K (53.1 miles) in six hours.

She’s grateful for the opportunities Lululemon is providing and is excited to see what continued sports science testing with the Canadian Sports Institute will reveal, especially as it relates to adapting to training and racing through perimenopause.

“It’s important for the general visibility of women and showing what happens when a brand really gets behind women,” Herron says. “Most sports science is based on men, but we’re studying women. I mean, we’re making it happen. The support from Lululemon has just been incredible. And it just goes to show what happens when women are supported in sports. It feels like there’s no ceiling.” 

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.

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.

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.
