What You Have to Know
Creator Allison Mercer competed for Crew USA on the 2026 IAU 100K World Championships in Ames, Spain, on September 20, the place she completed fifteenth. Individuals Charlie Lawrence and Courtney Olsen swept the person titles and the American males narrowly received the staff competitors for the primary time within the occasion’s storied 39-year historical past. Mercer attracts on her personal expertise, in addition to insights from Lawrence and Olsen, to make her case for why this format is worthy of your consideration.
America received a operating world championship final weekend.
Did you hear about it?
Most likely not.
That’s partly as a result of one other highway operating world championship was happening in Copenhagen on the identical weekend, with the mile, 5K, and half marathon drawing the eye of the operating world. These races have apparent enchantment: They’re quick, acquainted, straightforward to grasp, full of huge names, and more and more straightforward to package deal for tv and social media.
And it’s partly as a result of not that many individuals take note of highway operating past the 26.2 distance.
Whereas eyes had been turned to Denmark, the 100-kilometer highway operating world championships placed on by the Worldwide Affiliation of Ultrarunners (IAU), was happening in Ames, Spain. There, runners spent greater than six hours circling a 5K course as temperatures climbed from a cushty 61degrees Fahrenheit to over 90 levels and 87% humidity. That championship was nuts. It was thrilling. It showcased a few of the easiest of American distance operating. And it deserved a much bigger viewers.
Earlier than I am going any additional, I ought to state my biases, as a result of I’m fairly biased: I ran for Crew USA and completed fifteenth within the girls’s race. However that additionally makes me uniquely certified to let you know why the race—and highway ultras at massive—are so particular:
For starters, Crew USA captured the person title in each the boys’s and ladies’s occasions. After DNFing from the final highway 100K world champs in 2024 as a result of harm, Charlie Lawrence from Boulder, Colorado, received the boys’s race in 6:09:25. He pulled away from Lithuanian world-record-holder Aleksandr Sorokin simply earlier than midway and finally prolonged his result in two minutes.
“I knew at that time it was mine to lose, and I wasn’t going to,” Charlie instructed me. “This has been the massive race on the calendar for the final two years. It means so much.”
Charlie averaged 5:56 minute-per-mile tempo, the equal of operating back-to-back 2:35 marathons after which some.
In the meantime within the girls’s race, Seattle’s Courtney Olsen handed Miho Nakata with lower than 10 miles to go to maneuver into the lead. She received by a minute in 7:10:31—that’s 6:50 mile tempo, for 62 miles. The wildest half about it’s that Olsen, who had been feeling overworked and overwhelmed at dwelling, virtually didn’t even fly to Spain.
“I used to be very near not coming in any respect and the one purpose I did was as a result of I bought all the pieces as nonrefundable and I didn’t wish to let the ladies’s staff down,” she stated.
And there’s extra: The American males put collectively the sort of staff efficiency that Hollywood goals about. The staff occasion is scored by the mixed instances of the highest three finishers. Crew USA’s outcome was ok to beat Nice Britain for gold—by simply 44 seconds.
Not for the Faint of Coronary heart (or Abdomen)

Forty 4 seconds over three runners and 100 kilometers is nearly inconceivable to wrap your head round. It’s straightforward to really feel like you could have on a regular basis on the earth to make errors in a race this lengthy, however these 44 are a reminder of how each little element compounds. How aggressively do you begin? How a lot do you drink? When do you soak up energy? How do you reply when the temperature immediately rises? And, maybe most significantly, how a lot do you could have left when everybody else is starting to disintegrate?
“You might want to have the fueling dialed. You must have the pacing proper. The cooling perfected. There are such a lot of different components you have to good to place up an incredible efficiency,” Charlie stated. “It’s a real distance that may push you.”
That’s what makes elite highway ultrarunning so compelling. It’s not merely about surviving a ridiculous distance. On the world championship stage, these athletes are racing. They’re operating quick sufficient to make the marathon seem like the midway level after which asking their our bodies to maintain going for an additional 36 miles.
The situations in Spain made these achievements much more spectacular. The morning started comparatively cool, however the temperature climbed sharply because the race progressed. Shade was restricted, the pavement mirrored the rising warmth that even a summer time of coaching in Atlanta didn’t put together me for, and runners needed to handle the accumulating stress on their our bodies with no reprieve. In contrast to in path ultras, you don’t get an excuse to hike for a minute on the steep or technical sections as a result of there are none.

“Street ultras generally are a large take a look at,” Charlie instructed me. “You’re going at a tempo that you simply’re not fairly positive you may maintain for the entire distance and you realize you’re most likely going to be holding on for pricey life sooner or later.”
Past the sheer athleticism, an entire lot can go incorrect. There are upsets and battles inside battles. It’s fairly compelling stuff. But within the U.S., ultrarunning—and particularly highway ultrarunning—nonetheless exists exterior the mainstream operating dialog.
That’s unusual if you take a look at what different international locations have performed with the game. In South Africa, the Comrades Marathon and Two Oceans Marathon have turn into cultural establishments. They don’t seem to be handled as obscure races for a small group of people that occur to take pleasure in operating very far. They’ve historical past, rivalries, heroes, traditions, spectators, and a spot within the nation’s sporting identification.
America has the elements to construct one thing comparable. We have now the races, the communities, and more and more, the athletes able to competing for world titles. We have now the livestreaming capabilities. What we do not need but is identical stage of consideration and cultural recognition.

Perhaps that adjustments when folks truly see what these runners can do. In fact, higher TV protection (or any TV protection) would assist. The subsequent time a 50K or 100K comes via your space, go watch. Higher but, in case you are a runner, enter one. You do not need to be able to operating six hours at Charlie or Courtney’s paces to understand what is occurring. Stand alongside the course and watch the leaders come via. Take a look at their splits. Take into consideration how far they’ve already gone and the way a lot farther they nonetheless should run.
Then do not forget that these will not be folks merely attempting to complete. They’re racing one another, making tactical choices, managing warmth and vitamin, and looking for one other gear after their our bodies have already been working for hours.
Or don’t—Olsen, for one, actually doesn’t care.
“It’s in my nature to love issues that aren’t so hip,” she stated. “This sounds pretentious or self-satisfying, however I additionally suppose I like issues forward of their time, which means I can foresee however I’m additionally ill-timed. I can completely see the highway 50-mile and 100K turning into attention-grabbing to folks as soon as I’ve exited it, figuring out my luck.”

She’s used to the feedback about highway ultras being for “no names who couldn’t excel on the marathon and needed to transfer up.” And he or she’s used to tuning them out.
“I like all of the folks I get to fulfill and the locations I get to see due to operating this distance,” she stated. “I care an entire lot extra about rising my world view than getting an individual or a sponsor to see the worth.”
The 100K distance is the crown jewel of highway ultrarunning, with the world championship at this distance courting again to 1987, 39 years in the past. The U.S. simply produced two particular person 100K world champions and its first ever males’s staff world championship. The boys’s staff received by 44 seconds. That’s not some obscure outcome buried on the backside of the operating world.
It’s a story about American endurance athletes reaching the best stage of their sport. We needs to be paying consideration, as a result of if we begin celebrating these performances now, maybe the following technology will develop up seeing highway ultrarunning not on the fringe of operating, however as one other testing floor the place Individuals can race the perfect on the earth.
