Inside the spectacle of ultrarunning’s most festive top-tier 100-mile race

It’s a hot, sunny Saturday afternoon in the desert northeast of Phoenix, and Lindsay DesRochers is being chased by a dinosaur—as if 85-degree heat, a creaky left knee, and a hot spot on her right big toe aren’t enough to worry about during her first attempt at running 100 miles.

The 44-year-old senior creative recruiter from Scottsdale is 41 miles into the Javelina Jundred, and she also has to contend with a Tyrannosaurus rex who’s making her giggle. The dinosaur is, in fact, local trail running legend, Jerry Bloom, who is sweating and gasping for air inside an inflatable costume that’s kept afloat with a tiny battery-operated fan. He is dressed up as the dino-in-residence and runs alongside DesRochers briefly as she finishes the second loop of the five-lap course before sitting down to refuel and rehydrate in her crew tent.

“The problem with this thing isn’t the heat. It’s just that there’s no oxygen in here. If you run very far, you get oxygen deprivation,” says Bloom, 70, a three-time Western States and Hardrock 100 finisher who’s also run Javelina twice. “For me it’s all in good fun to support Lindsay. I’ve given up trying to be fast a long time ago. But what I’ve learned is that it’s not how far you go and it’s not how fast you go, it’s how you look while you’re doing it.”

Welcome to the Javelina Jundred—the biggest, wildest party in the trail running world.

It’s pretty obvious that the Javelina Jundred is the zaniest event in trail running and, to be frank, nothing even comes close to this dusty desert cavalcade of curiosities. It’s not quite the Burning Man of running, but it might just be better because, first and foremost, it’s a legit ultrarunning event.

More than 850 enthusiastic runners toed the starting line at 6 A.M. to begin the five-lap 100-miler, and about 400 more began the three-lap 100K an hour later. There’s also a single-loop, 19-mile nighttime race called the Jackass Night Trail for about 200 runners that includes a wild DJ’ed party at the Jackass Junction aid station and finishes as the Saturday night revelry is still going strong back at the race compound.

But because Javelina always happens on the weekend before Halloween, there’s a natural party vibe and a non-mandatory-yet-compelling reason for runners, pacers, and support crew to wear costumes. And, let’s face it, Halloween gives everyone license to fly their freak flag, so when you mix that with ultrarunning, just about anything goes. Only here it’s known as Jalloween.

This year’s most popular dress-up themes seem to be tropical and western, but, almost predictably, there are quite a few Barbie and Taylor Swift cosplayers, as well as a few heavy metal rock stars, glow-in-the-dark skeletons, and several very creepy clowns. Dozens more runners race through the desert wearing bunny ears, fox tails, and devil horns.

“This is a safe space for everyone to have fun in their own unique way,” adds Dan Gampon, a Hoka sports marketing representative from Hawaii. “It’s a fun way to give the people a chance to be weird and bring a part of themselves that they might have been wanting to bring out, and give them the opportunity just to have fun anyway they want to.”

Some crew tents are decorated with accouterments to match a particular theme, but most feature colorful holiday twinkle lights, camping chairs, sleeping bags, and coolers full of adult beverages. While there’s a stash of fancy engineered nutrition supplements and electrolyte drinks in every tent, there’s also the widest range of healthy and not-so-healthy snack food you can imagine. (I’m looking at you, guy simultaneously drinking a Red Bull and eating a handful of marshmallow Peeps.)

The Javelina staff and volunteers are fully into the Jalloween theme, too, especially race director Jubilee Paige, who dons several costumes during the 30-hour event—including getups she calls Race Director Barbie, Weird Barbie, The Dude, Cousin Eddie, Chef’s Kiss, and A Macaroni Penguin. She once again ends the event dressed as the Pope—a.k.a., “her Joliness”—because she considers Sunday “Jallelujah Javelina,” a day of celebration.

The Javelina Jundred was founded in 2003 by Phoenix ultrarunner Geri Kilgariff as an irreverent, party-oriented run on a multi-loop course, and gradually gained regional and then national popularity as word spread through the ultrarunning community about how much fun it was. Local ultrarunner Jamil Coury took over as race director in 2008. The next year he started Aravaipa Running, a Phoenix-based company that bought and now owns 75 other running events in Arizona, Colorado, Utah, Nevada, and New Hampshire.

Despite increased popularity and significant growth, Coury, Paige, and the rest of the Aravaipa crew have been able to maintain Javelina’s grassroots experience while growing it to about 1,500 runners in three events with at least that many pacers, crew, and family members hanging around the race compound. In many ways, it represents the best of both where trail running has been, but also where it could be heading.

“The race was born from a fun spirit of running with friends and looping in the desert—shout-out to Geri Kilgariff for her creation of the event in 2003,” Paige says. “But as it’s evolved, we saw opportunities to elevate the race to an ‘event’ experience for runners and crews—an ultra festival—the music and lights and entertainment just enhances that experience. However you experience Javelina, I just want you to have fun!”

As the sun begins to set, several top competitors in the 100-miler are scattered out on the remote sections of the course in hot pursuit of four Golden Ticket entries into next summer’s Western States 100. (Two tickets each for the men’s and women’s races.) That includes Boulder, Colorado, runner Jonathan Rea, who is back after a second-place finish a year ago, and—with newfound confidence from a fourth-place finish at the CCC 100K in Chamonix, France—is tearing up the desert trails on course-record pace. Triathlete-turned-ultrarunner Heather Jackson, who splits time between Bend, Oregon, and Tucson, Arizona, also takes it out hot, hoping to make up for a frustrating fifth-lap fade last year after unbearable quad pain reduced her to a walk and forced her to settle for a fifth-place finish in her 100-mile debut.

Earlier in the day, Denver’s Rajpaul Pannu and San Francisco’s Anna Kacius made quick work of the less-competitive, three-lap 100K race, finishing first and second overall, respectively, and setting new men’s (7:15:53) and women’s (8:13:07) course records in the process, while winning by more than an hour over their nearest competitors.

Ultrarunning GOAT Courtney Dauwalter from Leadville, Colorado, is out there, too, but she’s not racing for the win. She’s running the 100K with her mom, Tracy, a 66-year-old avid trail runner from Edina, Minnesota. They attempted a 50-miler in Minnesota last fall, but were timed out before the finish, so this year they chose the big party race in the desert where Courtney set a course record in 2016 before she became a household name. They’re not in costumes, but they’re running as Team Bucket List and wearing matching white shirts, cactus-themed socks, and olive-green-and-black shorts.

Because runners constantly revolve through the turnaround point at the start/finish area, everyone else is always on the move throughout the race compound. Some are drinking craft beers and mingling as they wait for their runners, while others are watching the race livestream on their phones or from the jumbotron in the Javelina Jeadquarters circus tent. Still others are devouring freshly cooked artisan pizzas made to order in the Freak Brothers Pizza mobile brick wood-fired oven.

Rousing cheers and applause catch everyone’s attention every few moments as an elite runner arrives—including the ever-smiling Jackson, who quickly heads out on her fifth and final lap with a 30-minute lead in the women’s 100-miler.

“Heather is just amazing,” says Troy Brown, 48, a trail runner from Coto de Caza, California. “She’s always smiling. I’m just a fanboy, but I like anyone who can smile that much through pain.”

After Jackson runs out of sight, Brown quickly shifts his focus to getting his feet into an inflatable T-Rex costume so he can participate in the costume contest, an informal event that brings out a sheriff riding an inflatable rooster, Minnie Mouse, a foursome of Teletubbies and, of course, several dinosaurs. There’s also a guy dressed as Aladdin wearing a large golden lamp around his waist who is joined by a scantily clad Jasmine character who not-so-discreetly rubs the lamp in a Not Suitable for Work (NSFW) scene that draws both raucous laughs and shocked gasps from the crowd.

One of the best dressed-up groups of the event is a foursome of women from California’s Healdsburg Running Company: Dominique Chevalier (“Western Barbie”), Krista Kappus (“Alien Barbie”), Saddie Alloway (“Rootin’ Tootin’ Diva Barbie”), and Susan Oh (“Disco Bob Ross”). But the costume contest winners are the Montana Mermaids, a bikini-and-grass-skirt trio from Bozeman—Lena Romeo, Kara Haskell, and Liv Bleskin—who were there to crew and support elite runners Rachael Norfleet of Montana in the 100K and Utah’s Ryan Montgomery in the 100-miler.

The sun begins to set, but the party’s just getting started as DJ Colter Stillwell pumps tracks through the sound system as a full moon rises in the eastern sky. One of the rowdiest dancers is Brendan O’Hara, a Colorado trail runner who’s dressed up in a red-and-white mouse outfit with flashing lights similar to what popular Canadian electronic musician Deadmau5 wears on stage. As lots of energized runners entered in the Jackass race are about to head out into the night, two professional fire dancers perform a mesmerizing routine adjacent to the start line.

Just after dark, Rea comes flying into the finish area, stopping just short of the finish line to pantomime deadlifting a colossal barbell before crossing the line in a new course record of 12:43:10. Seattle runner Blake Slattengren stopped the clock next in 12:58:07 to claim the second Golden Ticket, while Montgomery ran another strong race to take the final podium spot in 13:01:14.

Redeeming herself from last year, Jackson finishes strong to win the women’s race and finish sixth overall, thanks in part to the aggressive pacing of Devon Yanko. Jackson’s time of 14:24:47 is the second-fastest women’s time ever behind Camille Herron’s 14:03:23 course record from 2021. Spain’s Ragna Debats (14:55:27) outran Riley Brady (15:29:17) to earn the second women’s Golden Ticket.

Not long after midnight, the Dauwalters finish, too. Covered in dust, sweat, and even a little bit of blood—Tracy took a tumble on the first lap early the previous morning—they cross the finish line after 17 hours of running with big smiles and hug in a classic mother-daughter moment. Late Sunday morning, DesRochers makes it to the finish line, too, in 27:31:41, battling hard to overcome dehydration, an upset stomach, and nagging hip flexor pain at various points during the race.

“I was prepared for it to be hard, and I knew I was going to hurt. At some point, I was like, Oh, right, this is what running 100 miles feels like,” DesRochers says. “It was difficult, but I kept my positive mental attitude the whole way. I have a buddy who has a saying, ‘Forward is a pace,’ so I kept repeating that and kept putting one foot in front of the other and I didn’t quit.”

Something that’s especially apparent at Javelina is that everyone is celebrated as an equal, regardless of finishing times, trail running experience, athletic ability, age, or any other dissimilar details. The event goes out of its way to create an environment that promotes visibility and inclusion for everyone, and the community of participants seems to embrace it by cheering and encouraging for everyone the same.

It has partnered with Native Women Running, Latinos Run, and Black Men Run each of the past several years to bring their runners to the race, and it was also one of the first ultra events to offer a non-binary category. This year there were six non-binary runners racing over its three races, led by Willow Dolde in the 100-miler (20:01:29), Andreas Anderson in the 100K (13:54:30), and Tasha Hartwig in the Jackass 31K (6:42:07). (Although Brady, a non-binary runner from Boulder, was competing in the women’s division because they were racing for a Golden Ticket, they were also, unofficially, the top non-binary runner in the race.)

As the golden hour comes and goes early Sunday afternoon—and final finishers Holly Sitzmann,  Jim Buckley, Brittany Edmiston, and Leslie Astle squeeze under the 30-hour cutoff with help from their pacers and crew—it’s clear that everyone at Javelina is celebrated equally and enthusiastically. That also includes two unofficial finishers—Rayna Rodriguez and Tatiana Orozco—who complete the 100-mile course just outside of the time cutoff, but are welcomed by a scream tunnel of remaining spectators and the adulation of Paige even though neither will receive a finisher’s buckle.

“Javelina is a celebration, and the invitation to run and participate at Javelina extends to everyone,” Paige says. “I want to ultimately show how amazing the community is and that this sport is for everybody and every body—the spirit of ultra is diverse and should be celebrated.”

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.
