A group of top ultra runners will gather in Chandler, Ariz., with hopes of breaking the World Athletics records for 100 kilometers on the road. The event, called Project Carbon X 2 and staged by Hoka One One for the benefit of their athletes, will start and finish at the Wild Horse Pass Motor Sports Park and will use some of the same roads as The Marathon Project which was held with great success last month.

“I’m incredibly excited,” said Hoke One One president Wendy Yang on a video conference today with reporters. “Also feel super fortunate that the team was able to bring this event together.”

The pandemic has meant dramatically fewer competitive opportunities for road running athletes, especially ultra runners who specialize in distances longer than the standard marathon distance of 42.195 km, or 26.2 miles. However, since most ultra runners train alone or in very small groups, the pandemic has given them a chance to put in long blocks of uninterrupted, COVID-safe training and improve their strength and fitness. Tomorrow’s race will offer them a chance to show off their work.

We wanted to give our athletes the chance to compete,” Yang continued. “We felt like our athletes really needed this chance.”

The top targets for tomorrow’s race are the ratified World Athletics 100-K records of 6:33:11 for women, set by Japan’s Tomoe Abe in 2000, and 6:09:14 for men, set by Japan’s Nao Kazami in 2018. Both records were set at the same event, the Lake Saroma 100-K in Hokkaido, Japan. The women’s record works out to a pace of 3:56 per kilometer, which means running two 2:46 marathons back-to-back plus another 15.6 kilometers at the same pace. The men’s record pace of 3:42 per kilometer translates to running back-to-back 2:36 marathons plus the extra distance.

“You never know what can happen in an ultramarathon,” said Hayden Hawks one of the top contenders in the men’s division. Hawks smashed the course record at the venerable JFK 50 Mile (80.5 km) in Maryland last November, clocking 5:18:40. His pace at that event, which included rugged trails and some steep climbs and descents, worked out to 3:58 per kilometer. He said he’s been practicing on flat, loop courses to simulate the conditions in Arizona, and that with his strength and mental toughness he has a chance at the record.

“My greatest strength is probably just my stubbornness,” Hawks said. He added: “I feel like I have this mental strength to push through a lot of pain.”

Hawks’s main rival tomorrow will be ultra star Jim Walmsley, the man whose record he broke at the JFK race. Walmsley is best known as a trail runner, and is the course record holder for the impossibly difficult Western States 100-Miler in Auburn, Calif., where he ran 14:09:28 in 2019 (he also won in 2018). Walmsley already holds the world best for 50 miles on the road of 4:50:08. Using the popular Riegel Formula, that’s equivalent to 6:05:51 for 100-K, comfortably under the 100-K world record by more than three minutes.

Note: Walmsley was on the LetsRun.com Track Talk Podcast this week where he talked about his 100-k world record attempt, his big plans for 2021 and his cancelled 2020. Highlights here.

“I’m really looking forward to improving on my past performances in the 100-K,” Walmsley said today, admitting that he hasn’t yet perfected his approach to that distance yet. He continued: “I think I’m bringing a more mature approach of being more patient.”

If they don’t eclipse the world record, both men could surpass Max King’s USA record of 6:27:44 set in 2014.

On the women’s side, Camille Herron is the top entrant, and she rated her fitness at “80 to 85 percent.” Like Hawks, the holder of the world best for 24 hours on both the road and the track recently won the JFK 50-Miler. She played down the possibility of getting the world record, but said she was in about the same shape as when she won the famed Comrades Marathon in South Africa in 2017 over a distance of 86.73 kilometers. She allowed that a personal best (sub-7:08:35) was possible, despite only doing a six-week build-up.

“I’m definitely confident in my fitness,” said Herron who recently switched sponsors from Nike to Hoka One One and who will be doing her first race in Hoka shoes. She added: “I’m getting fitter every week. I have a pretty good idea of what I’m capable of.”

Also competing in the women’s division is Irish Olympic marathoner Caitriona Jennings, 40, who will be making her 100-K debut. Jennings will be taking a cautious approach to the race because she is 12 weeks pregnant. She said that there will be plenty of ice and fluids available on the course so that she can keep her core temperature in check.

“It wasn’t a decision I took lightly,” she said emphasizing that she had consulted with her doctor before agreeing to compete. She added: “I think (the water and ice on the course) will help with hydration and keep my temperature down.”

The athletes will start and finish on the race track, and will run about nine laps of an 11-kilometer circuit (Walmsley estimated that each full lap would take him about 41 minutes). The course was measured by two World Athletics “A” measurers, Joe Galope and Jay Wright (an “A” measurer must be used in order for a course to be eligible for a World Athletics record). The event will have in-competition drug testing done by the USA Anti-Doping Agency, also a requirement for setting a world record.

All of the competitors will be wearing the new Hoka One One Carbon X 2 shoe. Colin Ingram, Hoka’s director of product, called the new shoe “one of our sharpest tools in the box.” He explained that the shoe had been improved over its predecessor by incorporating “swallow tail construction” to improve deceleration on the foot strike, and lowering the carbon plate to get it closer to the ground.

“It allows for a more natural gait,” Ingram said.

While Hoka One One has not disclosed the cost of the event, it is significant, especially making it as safe as possible from the coronavirus. Mike McManus, Hoka’s director of global marketing, said that every athlete had at least three antigen PCR tests in the last week, and that masks and social distancing were required at all times except when the athletes are on the course. An industry insider contacted by Race Results Weekly estimated the cost of COVID mitigation for the event was around $60,000.

“It’s been a huge challenge for us to make this event happen in a very safe way,” McManus said.

The race will be streamed live and free at hokaoneone.com beginning at 9:00 a.m. Eastern Standard Time.

Three extraordinary performances that captivated the athletics world have now been officially ratified by World Athletics, with Jacob Kiplimo, Ja’Kobe Tharp and Emmanuel Wanyonyi securing their places in the history books with remarkable world-record performances.

Uganda’s Jacob Kiplimo delivered a breathtaking 57:20 at the EDP Lisbon Half Marathon on 8 March 2026, producing what was then a spectacular world record. His performance underlined his exceptional ability over the half-marathon distance and further strengthened his status as one of the finest road runners of his generation.

American hurdler Ja’Kobe Tharp created his own piece of history in Eugene on 10 June 2026, storming to 12.75 seconds in the 110m hurdles. The sensational performance came with a legal +1.0m/s following wind and established Tharp as the new world record-holder, marking a remarkable breakthrough on the global stage.

Kenya’s Emmanuel Wanyonyi completed the trio with a sensational 2:11.83 world record in the 1000m. The Olympic champion produced the performance in Monaco, lowering Noah Ngeny’s long-standing 2:11.96 world record from 1999. It was another extraordinary demonstration of Wanyonyi’s speed, strength and versatility beyond his specialist 800m distance.

What makes the three records particularly special is the variety of disciplines involved. Kiplimo conquered the demanding half marathon, Tharp mastered the technical challenge of sprint hurdling, while Wanyonyi extended his middle-distance brilliance over 1000m. Each performance showcased a different form of athletic excellence, yet all three athletes reached the same extraordinary destination: the world-record books.

Accuracy Note: Kiplimo’s 57:20 has since been surpassed by Ethiopia’s Yomif Kejelcha, who ran 56:51 at the Media Maratón Ciudad de Buenos Aires on 23 August 2026, taking 29 seconds off Kiplimo’s mark. The newer performance was still listed as pending ratification, meaning Kiplimo’s mark had been overtaken on the clock even as his record was among those formally ratified.

The ratification of the Kiplimo, Tharp and Wanyonyi performances nevertheless gives official recognition to three spectacular moments that will remain significant chapters in the 2026 athletics season.

Three athletes. Three extraordinary performances. Three officially ratified world records. From Lisbon to Eugene and Monaco, Kiplimo, Tharp and Wanyonyi have added another unforgettable chapter to the story of athletics

Uganda’s rapidly rising distance-running star Harbert Kibet has been provisionally suspended by the Athletics Integrity Unit (AIU) over the alleged presence and use of prohibited substances.

The 21-year-old is facing allegations involving triamcinolone acetonide and exogenous steroids, with the substances reportedly confirmed through Isotope Ratio Mass Spectrometry (IRMS) analysis. The development brings an abrupt halt to what had appeared to be the emergence of one of Uganda’s most promising young distance-running talents.

Kibet had enjoyed a remarkable breakthrough in February when he made his road 10-kilometre debut at the 10K Facsa Castellón in Spain. He produced a stunning performance to win in a world-leading 26:39, a time that placed him at No. 4 on the all-time road 10K list at the time and immediately elevated his status in international distance running.

His rapid rise had already earned him opportunities to represent Uganda on the global stage. Kibet competed for his country at the World Championships in Tokyo last year, although he did not progress beyond the heats.

His most recent competition came in May at the Xiamen Diamond League, where he finished 15th in the men's 5000 metres in 13:46.45. He has not competed since that race.

The provisional suspension now casts uncertainty over the immediate future of an athlete whose spectacular 10K performance earlier this year had generated enormous excitement. However, it is important to stress that a provisional suspension is not a final finding of an anti-doping rule violation.

The case will now continue through the appropriate anti-doping process, during which the evidence and circumstances surrounding the allegations will be considered before any final decision is reached.

For Kibet, the development represents a dramatic and unexpected turn in a season that had begun with one of the most remarkable performances in the history of road distance running. The athletics world will now await further developments as the AIU process moves forward.

The women’s 100m hurdles is set for a spectacular showdown at the Brussels Diamond League Final on September 5, where Olympic champion Masai Russell will lead one of the strongest fields of the season in the battle for the coveted Diamond Trophy.

Russell arrives in Brussels in extraordinary form and as the athlete everyone will be chasing. The American star has enjoyed a remarkable season, combining consistency with breathtaking speed, and recently delivered another unforgettable performance when she ran a sensational 12.09 seconds in Zurich to break the world record.

That performance further strengthened Russell’s position as the dominant force in the event. Her remarkable consistency has been equally impressive, with the Olympic champion winning all 10 of her finals so far this season. With 48 points, she also finished at the top of the Diamond League standings during the regular season.

However, the points race is now behind her. In Brussels, everything comes down to one final. The Diamond League Final offers no room for complacency, and Russell will have to defeat an exceptional collection of world-class hurdlers to leave Belgium with the Diamond Trophy.

Among her biggest challengers is Nigeria’s Tobi Amusan, one of the finest hurdlers of her generation and a former world record holder. The field also includes Dutch star Nadine Visser, Bahamas standout Devynne Charlton and Poland’s Pia Skrzyszowska, ensuring that Russell will face serious opposition over every hurdle.

American Alaysha Johnson, Jamaica’s Megan Simmonds and Belgium’s Yanla Ndjip-Nyemeck complete a fascinating eight-athlete lineup for what promises to be one of the highlights of the Diamond League Final.

With Russell’s unbeaten record, her recent world-record performance and the Diamond Trophy on the line, the pressure will be immense when the athletes take their marks. Yet in an event as unpredictable and technically demanding as the 100m hurdles, one mistake can completely change the outcome.

Russell may arrive as the overwhelming favourite, but Brussels offers her rivals one final opportunity to produce something special. The stage is set for a thrilling race between the fastest and most accomplished hurdlers in the world—and after a season of dominance, Russell now has one more hurdle to clear in her pursuit of Diamond League glory.

Women’s 100m Hurdles Final Start List

 1. Masai Russell — United States

 2. Tobi Amusan — Nigeria

 3. Nadine Visser — Netherlands

 4. Devynne Charlton — Bahamas

 5. Pia Skrzyszowska — Poland

 6. Alaysha Johnson — United States

 7. Megan Simmonds — Jamaica

 8. Yanla Ndjip-Nyemeck — Belgium

One race. Eight elite hurdlers. One Diamond Trophy. Will Masai Russell complete another unforgettable chapter of her remarkable season, or will Brussels produce a surprise?

The 2026 Bank of America Chicago Marathon is set to introduce an important new innovation that could change the way runners approach hydration during major road races.

For the first time, participants in an Abbott World Marathon Major will have the opportunity to refill their own approved, self-carried hydration containers while competing on the course. The initiative will make its debut through four Culligan Water Refill Stations strategically positioned along the 26.2-mile route.

The refill stations will be located shortly before Aid Station 4 at Mile 5.7, Aid Station 7 at Mile 10.1, Aid Station 12 at Mile 15.7 and Aid Station 16 at Mile 20.3. At each location, runners carrying approved personal hydration gear will be able to stop and refill with Culligan-filtered water before continuing their race.

The move represents a significant step forward for one of the world's most prestigious marathons. Chicago will become the first Abbott World Marathon Major to formally provide runners with the opportunity to refill personal hydration containers during the race, opening the door to a potentially more sustainable approach to supporting thousands of participants over the marathon distance.

Beyond the environmental benefits, the initiative will also be fascinating to watch from a sporting perspective. Hydration is a crucial part of marathon performance, particularly for runners competing over more than two hours and for the many recreational athletes spending considerably longer on the course. The effectiveness and convenience of the refill stations, as well as how smoothly runners are able to use them without disrupting their rhythm, will be closely observed.

The project is also designed to reduce reliance on single-use hydration products while giving runners greater flexibility and control over how they manage their fluids during the race. If successfully implemented, Chicago's new approach could provide an important example for other major endurance events around the world.

Culligan International President and Chief Operating Officer Al Hamood said the company's involvement reflects its wider commitment to innovation, sustainability and improving the race-day experience for athletes.

The 2026 Chicago Marathon will therefore offer much more than another spectacular day of elite racing and personal achievement. It will also serve as a live test of an idea that could help shape the future of hydration at major marathons.

When the 2026 Bank of America Chicago Marathon gets underway, runners will not only be racing against the clock—they will also be part of something entirely new. At four points along the legendary 26.2-mile course, a simple refill could become a glimpse into the future of marathon running. The real question will be how smoothly thousands of athletes embrace the system and whether Chicago's bold experiment can set a new standard for the sport. If it succeeds, the ripple effect could extend far beyond the streets of Chicago, inspiring major races around the world to rethink how they keep runners hydrated while reducing waste. In 2026, one of marathon running's biggest stages will be testing a small but potentially game-changing idea—proving that sometimes the future of the sport may be waiting at the next water refill station.

Indianapolis is set to become the home of American indoor track and field for the next two years after USA Track & Field confirmed that the city will host the 2027 and 2028 USATF Indoor Championships at the Indiana State Fairgrounds.

The nation’s leading athletes will compete at the Indiana Farm Bureau Fall Creek Pavilion, with the 2027 championships scheduled for February 19–21, followed by the 2028 edition from February 18–20.

The announcement marks a significant moment for Indianapolis and its long-standing connection with the sport. The 2027 championships will take place 40 years after the city hosted the inaugural World Indoor Championships at the Hoosier Dome in 1987, bringing another major chapter of elite indoor athletics back to a city with a rich track and field history.

Although Indianapolis is home to USA Track & Field's national office and has hosted major athletics competitions over the years, the upcoming editions will be the first time the city has staged the USATF Indoor Championships. The Indiana State Fairgrounds has nevertheless developed into an increasingly important venue for the sport, providing a major platform for elite indoor competition.

The consecutive championships will give athletes two years of high-stakes competition on one of America's growing indoor stages, with national titles and places among the country's finest athletes once again on the line.

The 2028 USATF Indoor Championships will carry even greater significance, serving as a selection event for athletes hoping to represent the United States at the 2028 World Athletics Indoor Championships in Odisha, India. That will add another layer of intensity to the competition as athletes battle not only for national honours but also for the opportunity to compete on the global stage.

For Indianapolis, the return represents more than simply hosting another national championship. Four decades after welcoming the world's finest athletes for the inaugural World Indoor Championships, the city is preparing to once again place track and field firmly in the national spotlight.

With two consecutive editions now secured, Indianapolis is ready to welcome America's best indoor athletes as they chase national glory, international selection and the chance to create another memorable chapter in the city's proud athletics history.
