Every fall, a group of Denver runners celebrates National Taco Day by running 31 miles using the fast food Mexican chain as aid stations

Imagine you’re 12 miles into a running race and you arrive at an aid station, where, instead of refueling with energy gels, you’re required to eat a 540-calorie Taco Bell Crunchwrap Supreme. 

Yes, that’s one of the mid-race snacks you’ll need to consume if you want to be an official finisher of a bizarre and spirited, 31-mile run through the greater Denver area.

Welcome, if you dare, to the annual Taco Bell 50K Ultramarathon. 

What started as an offhand suggestion on a Saturday morning training run has now become a stupid and fun gastro-intensive ultra-distance event with 10 “aid station” stops at various Taco Bell restaurants. But, as silly as it seems, it’s all about sharing the community of running, says founder Dan Zolnikov. 

Held every October for the past six years, and loosely coinciding with National Taco Day (yes, that’s a thing), it’s an unconventional and entirely unsanctioned fun run that has several ridiculous rules—a.k.a. the semi-optional Taco Bell 50K Commandments that are printed on the back of the event’s race bibs—including the need to eat something from the Taco Bell menu at every stop. 

While that could mean consuming something small at most of the restaurant visits—like, say, an order of Nacho Fries or Cinnamon Twists—the fourth and eighth aid stations demand a higher level of gastrointestinal fortitude. At those stops, participants must opt for one of the larger and more calorie-intensive “Supreme” menu items, such as a Crunchwrap Supreme, Burrito Supreme, or Nacho Cheese Doritos Locos Tacos Supreme.

“I always tell people it’s fun until the fourth stop,” says Zolnikov, a Denver lawyer and avid ultrarunner who started the event in 2018. “Most of those that are new to it are like, ‘Wait, I’ve gotta eat a Chalupa Supreme or a Crunchwrap Supreme and then keep running for almost 20 more miles?’ And we laugh and say, ‘Yep! That’s what we do.’ Honestly, that’s when a lot of people are like, ‘I think I’m just going to go home.’”

Running the Taco Bell 50K is what many ultrarunners call out-of-the-ordinary Type 2 fun—something that conceptually sounds fun before and afterwards, but in actuality is not quite that fun while it’s happening. But word has gotten out and it’s been compelling enough to have grown to a record 40 participants this year. There’s no entry fee, but each runner is expected to pay for their own food. 

While the Taco Bell chain of 7,000 Mexican-themed fast food restaurants isn’t a sponsor of the event—and the event organizers explicitly remind participants of that—a Denver-based Taco Bell franchise group agreed to open one of its locations early this year to accommodate the 7 A.M. start and welcome runners with free breakfast burritos, thanks, in part, to the persistent prodding of Jason Romero, one of the event’s original instigators.

Not just a zany group run, the Taco Bell 50K is rooted in ultrarunning lore and takes cues from some of the country’s most famous races. Not only does the course alternate between clockwise and counterclockwise every other year—a la Colorado’s Hardrock 100—it also requires runners to keep their Taco Bell food wrappers as an ode to how runners need to tear a page out of hidden books on the Barkleys Marathon course.

While Leadville 100 luminary Ken Chlouber has famously motivated runners for 40 years by saying “You’re better than you think you are, you can do more than you think you can,” Romero says the motto of the Taco Bell 50K is that “you’re hungrier than you think you are, and you can eat more than you think you can.” 

How does a convoluted event like the Taco Bell 50K get started in the first place? At a farmer’s market, of course. 

During long Saturday morning training runs in the spring of 2016, Zolnikov and running buddy Mike Oliva developed a habit of refueling by eating fresh, Colorado-grown or locally crafted food at Denver farmer’s markets. On one run, Oliva randomly stopped to use a bathroom at a Taco Bell and suggested to Zolnikov they should consider changing their route the next weekend and make Taco Bells their impromptu aid stations. 

“As soon as he said it, we laughed but then there was this awkward, five-minute silence between the two of us,” Zolnikov recalls. “We were just kind of jogging along and not really saying anything, but he said it so it was out there. I think we realized it was a stupid idea, but, as ultrarunners, we kind of wanted to do it. So I asked him, ‘Do you want to do that next week?’ And he was like, ‘No dude, just forget I said anything. Let’s just forget it.’” 

Although the idea never conjured up mouth-watering excitement, the odd craving to do it never went away. The banter about the idea continued on their Denver running Facebook group, as well as at weekly training runs of the Denver chapter of Achilles International, a running club in which runners with disabilities are guided on weekly training runs and weekend races. 

Oliva started that group in 2013, and it has met for weekly runs at Denver’s Washington Park every Monday night for the past 10 years, developing an easy-going camaraderie between guides and runners. 

“This talk about running to Taco Bells went on for about two years, and finally I got sick of hearing the trash talk, and just said, ‘That’s it, we’re doing it,” says Romero, 53, a regular Achilles runner who is legally blind. “And as soon as I said it, it kind of got silent. But I’m not about talking, I’m about doing. So I said, ‘You put together a course and we’re going to do this.” 

Within a few days Zolnikov had plotted out a course using Google Maps and Strava, connecting nine Taco Bells in the Denver metropolitan area in a 31.52-mile loop. (To make it an even 10 aid stations, the event starts and finishes at the same Taco Bell on the southwest side of the city.) And then, a few weeks later, in October 2018, seven courageous runners gave it a go and five finished in about seven and a half hours. (The other two tapped out, waving the white napkin of surrender midway through the route.)

Although it was mostly a celebratory season-ending fun run among a core group of friends for the first few years, it has garnered more interest as word of mouth spread. A few of the Achilles runners have joined in the fun every year.

“It’s not a glamorous route,” says Ben Garrett, who took over as race director after running the Taco Bell 50K for the first time in 2022. “It’s kind of what you’d call an urban ultra through the ‘scenic’ parts of Denver.”

Garrett, a 25-year-old structural engineer, was training for his first marathon when he was cajoled into joining the Taco Bell 50K—despite never having run more than 16 miles. He joined willingly and finished, giving him a boost of confidence heading into the Disney World Marathon three months later.

“It was great to know I could run that far before my marathon, especially knowing I had a stomach of steel after that,” Garrett says with a laugh. “But it also inspired me to run more. After my first marathon, I did another marathon and then a couple of 50Ks. Now I’m hooked for life.”

There are no winners, and there are no prizes. Instead over the years, runners have piled on extra gastrointestinal challenges for extra satiation. 

There’s the Baja Blast Challenge, which entails only imbibing two liters of Mountain Dew Baja Blast during the run, and then there’s the Diablo Challenge, which consists of oozing a packet of Taco Bell’s next-level hot and spicy Diablo Sauce on every single food item throughout the run. (By the way, two of the more precarious event rules state that no Pepto Bismal, Alka Seltzer, Pepcid AC or Mylanta will be allowed on the course, and the bathroom stops are only allowed at the Taco Bell restaurants.)

As if consuming 1,500 calories during the run wasn’t enough, some runners have added their own challenges—such as devouring a Voodoo Doughnut during the middle of it—and many runners engage in the Diablo Shooter Challenge, which is simply sucking down a packet of the restaurant’s fiery hot sauce to conclude the run. But to be fair, one of the forgiving commandments is the notion that every runner can take a mulligan and skip eating at one of the stops.

“It’s just meant to be a fun run,” says Denver runner Bill Garner, who has participated in five of the six Taco Bell 50Ks. “It’s the one ultra where you’re just really out there for the camaraderie. I don’t really feel like anybody’s racing, although I’m sure somebody’s going to show up one year and try to run it all-out. But for most of us, it’s a big camaraderie run.” 

It is mostly about the community spirit that pervades running, but for Garner, the Taco Bell 50K inspired him to run farther and pursue new running goals. Prior to participating in the first event in 2018, the 53-year-old cybersecurity technology specialist and strict vegetarian primarily ran marathons and half marathons on the roads. Since then, his focus has become ultra-distance races on trails, and believe it or not, he typically relies on cold Taco Bell bean-and-cheese burritos in his aid station resupplies.

“It’s the perfect ultra fuel,” says Garner, who consumed numerous Taco Bell delicacies enroute to finishing the Kansas Rails to Trails 100-miler in 2019. 

“I thought these ultrarunners were crazy, and I jumped into this because it was crazy, but then it changed my life,” he says. “I had never run an ultramarathon before I did the Taco Bell run, and I definitely learned that, if you just keep eating, you can keep going. That’s what ultras are all about.” 

A few years ago, Portland, Oregon, runner Bobi Jo Ousnamer befriended several Colorado runners in an online forum while training for the Pikes Peak Marathon. They told her about the Taco Bell 50K and asked her to come out and run it in 2019, but she couldn’t fit it into her schedule because she was training for her first 100-miler. 

However, she made it out for the 2020 edition, amid the Covid-19 pandemic. (That year, a small group of runners ran through Taco Bell drive-thrus to order their food because the inside dining areas weren’t open.) During the run, she admitted she had devised her own Taco Bell 50K course in Portland. That immediately sparked interest in doing Denver and Portland events on back-to-back days, which they finally pulled off in 2022 on the day of the Portland Marathon. 

That event included stops at seven Taco Bells and a marathon aid station a friend organized on her front lawn, where they devoured homemade breakfast tacos. Calling it the Double Deuce Challenge, it included 62 miles and 18 taco stops in two cities in less than 36 hours.

“I made the mistake of mentioning to Jason Romero that I had created a Portland course and he was like, ‘Oh my God, we’re doing a double!’” says Ousnamer, 34, who works as a juvenile public defender in Portland. “So for the fifth anniversary, he announced that we’d be doing this double. I think we all thought he was kind of joking, but as the months went on, he was like, ‘All right, I’ve got a plane ticket so we’re doing this.’ The Taco Bells are not as close together as the Denver ones and it’s hillier in Portland, so it was a bit of a bigger challenge. We were definitely feeling it on day two.”

Although the Taco Bell 50K has always meant to have been a low-key, end-of-the-season celebration for local runners, it’s continued to gain notoriety and to push the envelope of what’s possible. Runners in Texas and New Jersey have reached out about developing something similar, as have a couple of running clubs in Europe. Although the event details were typically only posted on Facebook when Zolnikov managed it, Garrett upped its visibility and inclusivity by developing an informational website with a link to the Strava map of the course.

Will the Taco Bell 50K continue to grow? 

“Honestly, I never wanted to see it start to begin with, but it’s kind of turned into this force of nature that’s bigger than me and bigger than Jason, and it’s become its own thing now,” Zolnikov says. “People can use it for whatever they want it to be, and if someone wants to get bragging rights for racing through it as fast as they can, go for it. My thing has always been about getting together and running, and, OK, ‘Let’s do this kind of dumb thing, and let’s have fun doing it.”

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.
