Conner Mantz, Clayton Young, and Leonard Korir will run in the International Pro Team Challenge on May 27.

Memorial Day is always an exceptional celebration for runners in Boulder, Colorado, but this year, it will have some extra special Olympic flair.

On Monday, May 27, more than 40,000 runners will run through the city that’s known for the iconic Flatirons rock formations, the Pearl Street pedestrian mall, and an exceptionally active population in the annual Bolder Boulder 10K. Now in its 44th year, it’s been one of the top road running races in the U.S. since its inception, and this year will serve as one of the final tune-ups for the men’s U.S. Olympic marathon squad before racing in the Paris Olympics later this summer.

Conner Mantz, Clayton Young, and Leonard Korir, the top three finishers in the 2024 U.S. Olympic Trials who will be racing the marathon in the Paris Olympics on August 10, will be competing as Team USA Red in the Bolder Boulder’s International Pro Team Challenge that follows the citizen’s races. (Korir is expected to officially be named to the U.S. team in early May based on final pre-Olympic international rankings.)

The pro race, which has a prize purse of $83,700 before potential bonuses, is one of the things that makes the Bolder Boulder so unique. After all the runners in 98 citizen waves have completed the race, professional men’s and women’s international teams from more than a dozen countries compete on the same course for team and individual titles. The races feature a staggered start, with women beginning 15 minutes before the men so the winners of each race will finish about 10 minutes apart inside the University of Colorado’s Folsom Field football stadium.

The finishing moments are among the thrilling spectacles in American running. By that point, the stadium is filled with a near-capacity crowd of roaring runners, family, and friends who have been watching the action play out on the massive video screens.

“The finish in the full stadium is like nothing else in the sport,” says Mantz, 27, who won the men’s race last year in 29:08 with a thrilling late-race surge to pass Kenya’s Alex Masai in the final 200 meters before the finish. “It was pretty electric. It took away all the pain you’re feeling mid-race. I was like, ‘Just race as hard as you can.’”

Team USA Red will have plenty of competition, from Team USA White, the secondary American team of Jared Ward, Futsum Zienasellassie, and Sam Chelanga, as well as teams from Kenya, Ethiopia, Mexico, and Rwanda. Teams are scored like a cross country race, with points awarded on the basis of finishing place, which means the team with the lowest combined score for all three runners is the winner. Ties are decided by the positions of the third-place finishers.

The women’s Team USA Red team will be led by defending champion Emily Durgin, along with Sara Hall and Boulder native Nell Rojas. Durgin finished ninth at the U.S. Olympic Trials in February and won the USATF 10 Mile Championships on April 7 in Washington D.C. At last year’s Bolder Boulder, she stormed to victory in 33:24, winning by 24 seconds over Kenya’s Daisy Kimeli.

Hall placed fifth in the U.S. Olympic Trials Marathon on February 3 in a U.S. master’s record (2:26:06) and 15th in the Boston Marathon on April 15. The women’s Team USA White roster will be composed of an all-University of Colorado alumnae squad—Makena Morley, Sara Vaughn, and Carrie Verdon.

“I can’t wait to be back in Boulder for the best day of the year,” says Durgin, 29, who will compete in the U.S. Olympic Trials 10,000 meters on the track in late June with the hopes of making the U.S. Olympic team. “Competing with Nell and Sara will make the experience even better.”

The women’s U.S. Olympic marathon team of Fionna O’Keefe, Emily Sisson, and Dakotah Lindwurm were invited to race in the Bolder Boulder but each runner declined, citing scheduling timing conflicts or a disinterest in racing at Boulder’s lofty altitude (5,430 feet). All of the runners who are racing for the U.S. teams in Boulder live at 4,500 feet or higher.

An Olympic Legacy

Boulder is known as one of the top running  meccas in the U.S., in part because elite-level American and international runners have made it their training base since Olympic gold medalist Frank Shorter arrived in the early 1970s. Emma Coburn, Jenny Simpson, Yared Nuguse, Joe Klecker, Jake Riley, Hellen Obiri, and Edna Kiplagat are among the many top-level runners who are currently training in Boulder.  Shorter, the 1972 marathon gold medalist, was a co-founder of Bolder Boulder 10K in 1979, and helped it grow into one of the country’s largest races. 

Since then, numerous U.S. Olympians have raced in the Bolder Boulder, including Deena Kastor (a three-time women’s champion), Aliphine Tuliamuk (the 2022 women’s winner), Alan Culpepper, Elva Dyer, Ryan Hall, Abdi Abdirahman, Jorge Torres, Shalane Flanagan, Amy Cragg, Magdalena Boulet, and Libby Hickman, as well as Korir (who won it in 2022), and Ward (who was fourth in 2022).

Thanks to Boulder’s robust running community and the prestige of the race, the Bolder Boulder has also always featured fast sub-elite runners competing in the early citizen waves. Yet, the race has also celebrated dedicated middle-of-the-pack runners, as well as the first-time runners and walkers in the later waves. It was one of the first races to have bands playing along the course (as well as belly dancers and other entertainers), runners dressed up in costumes, elite wheelchair races, and in recent years, it has been known for a mid-race slip-and-slide and unofficial bacon aid station.

For the past 25 years, the Bolder Boulder has organized a special Memorial Day tribute—one of the largest in the country—that honors military veterans and new cadets.

The U.S. men’s Olympic marathon team competing in this year’s Bolder Boulder will be a legacy moment for the race, says Bolder Boulder race director Cliff Bosley.

“Having the three men that will represent our country in the marathon at this summer’s Paris Olympic Games is something we are extremely proud of,” Bosley says. “All three ran here last year, and to have them back is just incredible for the race, the city of Boulder, and the sport of running.”

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.

Several other crucial dates will shape the road to the historic race. The substitution period will run from 15 to 31 March 2027, while 3 May 2027 is the final deadline for runners to submit their qualifying performances, seeding information and other required entry details.

To qualify for the 2027 Comrades Marathon, runners must complete a 42.2km marathon in under five hours between 15 June 2026 and 3 May 2027.

The journey will finally culminate on Sunday, 13 June 2027, when thousands of runners are expected to line up for the historic 100th edition of the Comrades Marathon.

The 2027 race will represent a remarkable moment for the legendary South African ultramarathon. For more than a century, the Comrades Marathon has captured the imagination of runners and spectators with its extraordinary test of endurance, determination and human spirit. Its centenary edition will celebrate the generations of athletes who have faced its demanding roads, conquered its challenges and helped build one of the world's most respected endurance events.

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.
