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.” 

The prospect of seeing one of athletics' biggest stars back on the track is growing stronger, with Jakob Ingebrigtsen reportedly targeting a return to competition later this summer following his recovery from Achilles tendon surgery.

According to comments made by his agent, Daniel Wessfeldt, in an interview with Norwegian media, the double Olympic champion could make his long-awaited comeback at one of three major European meetings in July. The leading options under consideration are the Monaco Diamond League on July 10, the Hungarian Athletics Grand Prix on July 14, and the London Diamond League on July 18.

For athletics fans, the possibility of Ingebrigtsen lining up in London would add another layer of excitement to an already highly anticipated Diamond League meeting. The Norwegian middle-distance sensation has become one of the sport's most dominant figures in recent years, collecting Olympic, world and European titles while consistently rewriting record books.

His 2026 campaign was put on hold after he underwent surgery on his Achilles tendon earlier this year, forcing him to focus on rehabilitation rather than competition. Since then, questions have surrounded when the 24-year-old would be ready to return to racing.

The latest update suggests that decision will largely depend on how his training progresses over the coming weeks. If recovery continues according to plan, July could mark the beginning of his return to elite competition ahead of the latter stages of the season.

A comeback at either Monaco, Budapest or London would immediately place Ingebrigtsen back among the sport's biggest storylines. Each meeting is renowned for producing world-class performances, and any appearance by the Norwegian would attract significant attention from fans eager to see how quickly he can regain top form after his injury setback.

While no final decision has been confirmed, the signs are increasingly positive. After months away from competition, Jakob Ingebrigtsen appears to be edging closer to a return, with London's Diamond League meeting emerging as one of the most intriguing possibilities on his road back to the track.

Should his recovery continue smoothly, athletics could soon welcome back one of its brightest and most influential stars.

What should have been the defining moment of Emad Bashir-Mohammed's young running career instead turned into one of the most talked-about controversies in American road racing this year.

The 23-year-old crossed the finish line first in the men's citizen's race at the prestigious Bolder Boulder 10K on Memorial Day in Colorado, stopping the clock at an impressive 29:50. His performance was not only a commanding victory but also one of the fastest winning times ever recorded in the event's long and celebrated history. Bashir-Mohammed finished eight seconds clear of his nearest challenger and appeared to have secured a breakthrough triumph.

For nearly two hours, he was the undisputed winner.

Then everything changed.

Race officials announced that Bashir-Mohammed had been disqualified after determining that he had started in the wrong wave. According to Bolder Boulder regulations, he had been assigned to the AA wave but lined up with the faster A wave, which began earlier. Event rules allow runners to move backward into a slower wave, but prohibit athletes from advancing into a faster one.

As a result, Bashir-Mohammed's victory was erased from the record books.

The citizen's title was subsequently awarded to Nickolas Scudder, who crossed the line second in 29:58. The promotion handed Scudder back-to-back citizen's race victories, while Bashir-Mohammed was left to grapple with the disappointment of losing a win he believed he had earned on the road.

The disqualification has since ignited widespread debate across the running community.

Bashir-Mohammed maintains that he did not intentionally violate the rules. He claims that after collecting his AA bib, he spoke with race personnel and was permitted to start with the A wave after presenting evidence of his recent performances. In a statement shared after the race, he expressed frustration over the decision, arguing that his goal was simply to compete against the strongest field available and produce the fastest time possible.

Race organizers, however, stood firmly behind their ruling. Officials stated that wave-assignment regulations are clearly communicated in pre-race information and reiterated during packet collection. They also noted that hundreds of participants are disqualified each year for moving into faster start groups, emphasizing that consistent enforcement is necessary to maintain fairness for all competitors.

The incident has divided opinion among runners and fans alike. Some believe the rules must be applied equally regardless of an athlete's finishing position, arguing that wave assignments are a fundamental part of race organization. Others feel the punishment is harsh, particularly if Bashir-Mohammed genuinely received approval to move up before the start.

What remains undisputed is the quality of his performance. On the roads of Boulder, Bashir-Mohammed demonstrated the fitness and speed required to outrun the field by a significant margin. Yet in road racing, crossing the finish line first is only part of the equation. Compliance with race regulations carries equal weight.

For Bashir-Mohammed, the day will be remembered as a painful lesson in the fine margins that can define elite competition. A remarkable run delivered a memorable victory, but a dispute over wave placement ultimately overshadowed the achievement, leaving behind a controversy that continues to fuel discussion throughout the running world.

A fast race, a costly administrative error, and a debate that may linger long after the finish-line tape has been packed away.

The men's 100 metres at the 2026 Rome Diamond League is shaping up to be one of the most anticipated sprint races of the season, with an exceptional field featuring some of the fastest men in the world.

Audrey Werro announced her arrival as one of the early stars of the 2026 outdoor season with a commanding victory in the women’s 800 metres at the Rabat Diamond League, producing a performance that exceeded even her own expectations.

The Swiss middle-distance talent surged to victory in a brilliant 1:56.56, breaking the meeting record and delivering one of the fastest times recorded worldwide this season. In a race packed with quality, Werro displayed exceptional composure, confidence, and finishing strength to separate herself from the field and stamp her authority on the event.

What made the performance even more remarkable was the athlete's surprise at the level she had already reached so early in the campaign.

"I was not expecting such a strong start to the season," Werro admitted after the race.

The race unfolded at a relentless pace, but Werro remained perfectly positioned throughout. As the athletes approached the bell lap, she glanced at the clock and immediately sensed something special was within reach.

"When I saw the time at the bell, I felt really confident," she said. "I'm really happy with the Meeting Record and looking forward to the rest of the season."

Her confidence proved justified. Maintaining her rhythm over the final 400 metres, Werro powered down the home straight to secure the victory and rewrite the Rabat meeting record books in the process.

The performance sends an early warning to her rivals ahead of a season that promises major championships and high-profile Diamond League battles. Beyond the record-breaking time, Werro's display highlighted her growing maturity as a racer, combining tactical awareness with impressive speed and endurance.

With the outdoor season only beginning, the 1:56.56 clocking suggests that even faster times could be on the horizon. If Rabat is any indication, Audrey Werro may be poised for the biggest season of her career.

Her emphatic victory in Morocco was more than just another Diamond League win—it was a statement of intent from an athlete determined to challenge the world's best throughout 2026.

The city of Boston is set to welcome back one of its most celebrated champions as Kenya’s Sharon Lokedi headlines a world-class field for the 2026 B.A.A. 10K presented by Mass General Brigham Cancer Institute on June 21.

Fresh from another remarkable victory at the Boston Marathon in April, Lokedi returns to the streets of Boston and Cambridge carrying both momentum and confidence as she aims to defend the title she captured in dominant fashion last year.

The two-time Boston Marathon champion has developed a special connection with the historic race city. In 2025, she produced a course-record performance of 2:17:22 to win the Boston Marathon before returning this year to claim another victory in 2:18:51, the second-fastest winning time in the event’s storied history. Her success has cemented her status as one of the premier road runners in the world.

Lokedi will be making her first competitive appearance since her marathon triumph and arrives as the reigning B.A.A. 10K champion after clocking 31:39 over the challenging 6.2-mile course in 2025.

“Boston has become a very special place for me,” Lokedi said ahead of the race. “The atmosphere created by the fans and the community is unlike anywhere else. I’m excited to return and give everything I have to defend my title.”

The women’s race promises to be highly competitive. American Olympian Rachel Smith, who finished second at the Boston 5K in April, leads the domestic challenge. Kenya’s strong contingent includes African 10,000m champion Gladys Kwamboka, former B.A.A. 10K runner-up Stacy Ndiwa, and experienced road racer Viola Cheptoo. British Olympian Jessica Warner-Judd adds further international depth to a field packed with proven performers.

The men’s race is equally impressive, featuring elite athletes from 13 nations.

Ethiopia’s Dawit Seare enters as one of the leading contenders after capturing the 2025 Boston 5K title and bringing the fastest 10K personal best in the field at 27:21. Kenya will be represented by an accomplished group led by Alexander Mutiso, winner of the 2024 London Marathon and runner-up at last year’s New York City Marathon.

Patrick Kiprop also arrives in outstanding form after securing victory at the prestigious BolderBoulder 10K on Memorial Day, while Alex Masai returns looking to continue his strong record in Boston. Masai recently finished ninth at the Boston Marathon and has earned three top-ten finishes at the B.A.A. 10K.

Among the international stars making their mark is South Africa’s Adriaan Wildschutt, who makes his race debut after an impressive season highlighted by victory at the NYC Half Marathon in 59:30. Ethiopia’s Olympic bronze medallist Hagos Gebrhiwet adds further quality to the field, bringing a wealth of championship experience and previous success in Boston.

Canadian national 10K champion Andrew Alexander, two-time U.S. Olympian Hillary Bor, marathon standout Ryan Ford, and reigning USA 25K champion Andrew Colley complete a field stacked with talent and depth.

With defending champions, Olympic finalists, national champions and rising stars all converging on Boston, the 2026 B.A.A. 10K is shaping up to be one of the most competitive editions in recent memory. For Sharon Lokedi, however, the mission is simple: return to the city where she has repeatedly excelled and add another memorable chapter to her growing Boston legacy.
