5,000 runners are expected to run this year’s Memorial Day 10K on May 29

At bedtime last week, legendary American distance runner Melody Fairchild regaled her 7-year-old son Dakota with tales of the Bolder Boulder 10K he plans to run this year.

One of the biggest road races in the world for the past several decades, the race sends 40,000 runners through the streets of Boulder, Colorado, on a point-to-point race that ends at the University of Colorado (CU) football stadium, full of cheering spectators and fellow runners.

“I told him it’s an amazing feeling to run into that stadium,” Fairchild says. “When you hit the field, the whole crowd is cheering for everybody. You feel like they’re cheering for you. He had this huge smile on his face.”

And if 50,000 people cheering isn’t enough, there’s also the famous slip-n-slide, numerous bands playing on the course, runners and spectators wearing outrageous costumes, and the military jet flyover by the Colorado Air National Guard you can feel in your bones. Named America’s All-Time Best 10K, it’s likely to be one of the biggest parties you’ll ever attend.

Fairchild recounted for Dakota her experience as the U.S. captain for the Bolder Boulder’s first International Team Challenge professional race in 1998.

“I remember looking out the window and seeing the stadium full. I was so nervous, I thought I was gonna vomit all over the floor,” she says. “When I walked out and they introduced me as the local hometown girl, the whole crowd roared.”

Fairchild ran her first Bolder Boulder at age eight. She went on to win the citizens’ race three times (1989, 1990, 1991) when she was a record-setting high schooler, became an All-American and NCAA champion at the University of Oregon, and then qualified for the U.S. Olympic Trials in the 10,000-meter run and marathon as a professional runner. But the Bolder Boulder has always held a special place in her heart, which is why she has continued to run it through the years and why she’s so eager to introduce Dakota to it.

The idea for the Bolder Boulder germinated in the mind of a father watching his five children participate in all-day track meets. It was the summer of 1978 at the upswing of the original American running boom, and runner and local businessman Steve Bosley had grown frustrated with the disorganized events and parents berating their children for not running fast enough.

Bosley, then 37, reached out to his friend, Boulder resident and international running icon Frank Shorter, a two-time Olympic medalist in the marathon, for help designing a race that would serve their community and promote the sport of running. The race would not only become a Colorado icon, it set a gold standard for road races around the world and helped elevate women’s running in unprecedented ways.

During the spring of 1979, Cliff Bosley, the current race director, went door to door with his Boy Scout troop, passing out posters to encourage neighbors to run his dad’s inaugural race. The poster announced a 4,000-participant cap and enticed Boulderites to “Run with Frank Shorter and Ric Rojas!” for a mere $6.50 entry fee. (Rojas was another local elite athlete who would go on to win the inaugural race in 1979. His daughter, Nell Rojas, a current professional runner, won the women’s citizen’s race 40 years later in 2019.)

Bosley recalls giving a man in his front yard a poster who threw it back in his face in disbelief. “‘Yeah right, 4,000!’ the man scoffed. “I was just a 12-year-old kid. You believe everything your parents tell you. I thought, ‘Dad says it could happen—why won’t it?!’”

The inaugural race saw 2,700 registrations. The next year, it doubled in size and live entertainment was added to the celebration. Participation continued to soar in the ensuing years and decades, eventually reaching 50,421 in 2010. With an average of 45,000 finishers over the past 10 years, it’s now the seventh-largest road race in the nation and the largest Memorial Day celebration in the U.S.

From its inception, the Bolder Boulder 10K offered equal prize money for the female and male winners. In 1984, it created a separate elite race from the citizens’ race. There was also a deliberate split in the women’s and men’s elite race so that both races could be showcased equally and covered live on the local TV broadcast. Today, it offers one of the largest non-marathon prize purses in the U.S., but this did not come without a lot of work.

Initially road races were precluded from paying prize money to athletes because it changed their amateur athlete status, preventing them from competing in the Olympics. In the early 1980s, Steve Bosley, then the president of the Bank of Boulder, worked with two local attorneys, Frank Shorter, and TAC (The Athletics Congress which was then the name of the national governing body for the sport; now it’s known as USATF), to create a mechanism using trust accounts for athletes to earn prize money. It was then paid into athletes’ individual trust accounts so they could draw living and training expenses. At the time these accounts were called TACTRUST Accounts, and the Bank of Boulder was the steward of 95 percent of all of these accounts on behalf of both American and international athletes from around the world.

One of the most circulated photos of the Bolder Boulder 10K is that of Shorter, the 1972 Olympic marathon champion, winning the 1981 race— the first time the race finished in the University of Colorado’s Folsom Stadium. But that same year, Ellen Hart, then 23, won the women’s race—although she says there was no finish line tape for the female winner.

“It was the most exciting thing I had ever seen,” she recalls. “Since I was a little girl, I had wanted to go to the Olympics. I thought, Oh my god. This is like the Olympics! I traveled to races all over the world and the BB was my favorite race.”

Hart would move to Boulder in 1982, and then win the race again in 1983 before the four-year reign of Portugal Olympian Rosa Mota. In many ways, Hart says, her success in the Bolder Boulder launched her career as a professional athlete.

She went on to place 11th at the inaugural women’s U.S. Olympic Trials Marathon in 1984, set an American record in the 30K, and won 18 world championship titles in triathlon and duathlon racing. “In terms of women’s sports, the Bolder Boulder was certainly more forward-thinking than any other race I ever attended,” Hart says.

The race organization was also ahead of its time when it began the Women’s High Altitude Training Camp, something it did not offer for men, in 1989. The 100-day program was designed to bring five talented post-collegiate female runners to Boulder to train prior to racing Bolder Boulder. Runners were placed in volunteer host families, provided an elite coordinator and a trail guide, and given access to a local gym and the university’s track to train.

New Jersey runner Inge Schuurmans McClory was a member of the 1990 team.

“I really didn’t feel worthy of national attention, but I applied for the program not even thinking I was going to get in,” she says. She was not only accepted, but she fell in love with Boulder and stayed.

“I went to graduate school here. I met my husband here. I coached cross country and track at CU. It sort of was the launching pad for the rest of my life, and I owe it to the Bolder Boulder and that high-altitude training camp,” says McClory, now a physician’s assistant who has trained cardiac patients—the Brave Hearts—for the Bolder Boulder since 2000.

Since 1996, there have consistently been more women (average 53-54 percent) than men completing the race. Cliff Bosley attributes this to his mom creating a walking division in 1984 so that her father, diagnosed with prostate cancer, could participate.

“We kind of look at it as a placeholder,” says Bosley, “You come in as a walker and now you’re on the continuum. Let’s help you become a jogger. Let’s help you become a racer.” This exemplifies the Bolder Boulder’s rallying cry, “Oh Yes You Can!” that it established in 1979.

The Bolder Boulder has always been defined by its strong community involvement, which includes an eager network of volunteers, aid stations staffed by local running groups, and the thousands of spectators who line the streets and fill the stadium. Historically, the race donates more than $100,000 to local nonprofits and community groups that volunteer. Even during the pandemic, the race still found a way to contribute.

“Knowing we could not stage the Bolder Boulder in-person, we created a virtual event called the VirtuALL 10K and offered it at no cost,” Bosley says. Thousands of T-shirts, designed for the 2020 race that went unused, were donated to shelters.

Another Bolder Boulder program that supports the community is the BB Racers Club. Created in 1996, the program prepares children for the race, so their experience is a positive one. Initially started as a middle school program, this club now includes elementary schools. Children who are signed up are given a special training program, coach, and starting wave. Fairchild’s Boulder Mountain Warriors club, of which her son Dakota is a participant, is training a large number of BB Racers this year.

Bosley is prepared for up to 45,000 participants at this year’s race on May 29. And just as they did 44 years ago, race organizers will serve participants a sack lunch and send them a postcard in the mail with their finishing place, pace, time, and ranking in their age group.

“I can still remember checking the mailbox every single day until it came,” says Fairchild. “It makes me emotional just thinking about how much attention to detail they’ve always given hundreds of thousands of people. They care so much. It’s not an accident that they are the best 10K in the world.”

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 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.
