On a gray morning in London, Sebastien Saoi entered the world of the impossible and made it seem inevitable.
For decades, the two-hour marathon has existed in the same mental space as the four-minute mile: a number so round, so clean, so close to what even the best human beings can do, that it has become less of a time and more of a philosophical boundary. Can anyone run 26.2 miles in under 120 minutes? And if they could, would it count?
On Sunday 27 April 2026, in front of hundreds of thousands of spectators lining the streets of central London, a 31-year-old Kenyan named Sabastian Kimaro Saoe answered both questions at the same time. He crossed the finish line at the mall in 1 hour, 59 minutes and 30 seconds. No asterisk. There is no censorship path. There are no rotating defibrillators to protect him from the wind. Just a chestnut, a world marathon leader, a drug-tested field, and the best runners on the planet chasing it.
The previous world record of 2:00:35, set by the late Kelvin Kiptum at the 2023 Chicago Marathon, hasn’t just fallen. It was blurred for 65 seconds.
Sawi was not alone in the hack. Ethiopian runner Yomif Kegelcha, who ran his first ever marathon, finished 11 seconds behind in a time of 1:59:41. Ugandan Jacob Kiplimo came in third place with a time of 2:00:28, which was also within Kiptum’s old record. Three men under the previous world record in one race. Two of them were less than two hours long.
He broke the four-minute mile in 1954. It took the second man 46 days to break it, and another 16 people followed within two years. The marathon lasted for about two hours with a deep breath between the first and second man through the door. It turns out that the walls are falling in bunches.
Sawe was born and raised in the Rift Valley, in a village called Barsumbi in Uasin Gishu District. The region is the most prolific incubator for long-distance running talent the world has ever known: Kiptum, Eliud Kipchoge, Faith Kipyegon, David Rudisha and a seemingly endless line of Kalenjin distance runners have all emerged from this patch of highland farmland in western Kenya.
But Sawi was, by the standards of Kenyan marathon kings, a latecomer. Kiptom ran 2:01 in his debut at the age of 22. Kipchoge was world champion in the 5,000 meters when he was a teenager. Sawi spent most of his twenties on the track and on the half marathon circuit, where he built an impressive but not yet historic career. He set a course record in the Rome Ostia Half Marathon in 2022, won the World Road Running Half Marathon Championships in 2023, and was part of Kenya’s gold-medal-winning team at the World Cross Country Championships.
His marathon debut came in December 2024 in Valencia. He won with a time of 2:02:05, one of the fastest debut times in history. He followed it up with a win in London in April 2025 (2:02:27), then in Berlin the following September (2:02:16, in warm conditions that almost certainly masked faster potential). Four marathons, four wins and a quiet trajectory point toward something bigger.
His Italian coach, Claudio Berardelli, described Sawi as calm, analytical, and highly focused. His fellow athletes and training partners paint a similar picture: a man who doesn’t waste words, doesn’t attract publicity, and doesn’t let the hype of sports keep him away from work. He trains at altitude in Kapsabet, in the heart of the Rift Valley, and lives a life that revolves almost entirely around preparation.
The ghost of Kelvin Kiptum loomed over the London Marathon long before the shooting.
Kiptum set the course record in London in 2023 with a time of 2:01:25, then ran 2:00:35 in Chicago in October of that year to set the world record. He was 24 years old, clearly an up-and-comer, and announced his intention to become the first man to run two hours in a sanctioned race at the Rotterdam Marathon in April 2024.
He never did that. On the night of February 11, 2024, Kiptom lost control of his car on the Eldoret-Kaptagat road in western Kenya. He and his Rwandan coach, Jervis Hakizimana, were killed instantly. A third passenger survived his injuries. His world record had been officially ratified by World Athletics just five days earlier.
The running world mourned not only the man, but the future he represented. Kiptum, almost everyone agreed, was the one most likely to break the first two hours. His death left an open question: Who would carry the torch he was denied the opportunity to carry?
Sawe has never claimed that mantle publicly. In the days leading up to London 2026, he played down talk of the world record, telling reporters that Kiptom’s record of 2:01:25 was his target. His coach Berardelli revealed that Sawi was injured during the fall and did not resume proper training until January. By February, the stated goal was simply to defend his title in London.
Conditions on Sunday were nearly perfect: overcast, cool, and little wind. The Pacers were tasked with splitting the halfway line 60:30, and they did their job. Sawe and five others passed the 13.1-mile mark in 60:29.
From there, Sawi started doing what he did best: running away from people.
With the players declining, Sawe and Kejelcha have emerged as the strongest runners in the field. Kiplimo held on bravely but was unable to keep up with his pace. The race became a private war between two men: one a four-time marathon winner chasing history, the other a novice with a previous half-marathon world record on his resume and who seemed to have no concept of what a reasonable first marathon should look like.
The closing speed of Sawe was amazing. The final 2.195km, from the 40km mark to the finish, were covered in 5 minutes and 51 seconds, at an average pace of around 4:17 per mile, which equates to a hypothetical marathon pace of around 1:52. This is the fastest person ever to cover this portion of the marathon distance.
After mile 25, Kejelcha finally gave up. Sawe turned off The Mall and it looked as sharp as it did in the beginning. He saw the clock. He punched the air.
“I’m very happy,” he told the BBC. “Towards the end of the race, I was feeling strong. The Ethiopian was very competitive. I think he was the one who helped me a lot. I finally got to the finish line, saw the time, and was very excited.”
Kipchoge, the man who ran 1:59:40 in the Ineos 1:59 Challenge in Vienna in 2019 (an unofficial, non-standard qualifying performance with spinners and a fast car), posted his congratulations through his social media account. He described it as a historic day and said it proved that humanity was “at the beginning of what is possible.”
Talking about shoes cannot be avoided.
Sawe wore the Adidas Adizero Adios Pro Evo 3, the shoe first used in the London Marathon. It weighs 97 grams (3.4 ounces) in a men’s size 9, almost 30 percent lighter than its predecessor, with a stack height of 39 millimeters less than the World Athletics legal limit. Four of the top five men wore Adidas gear.
It’s a paradox worth sitting with. Nike launched the Breaking 2 project in 2016 with the clear goal of engineering a sub-two-hour marathon. Kipchoge ran 2:00:25 in that controlled attempt in 2017, then broke 1:59:40 in Vienna in 2019, both in Nike prototypes. Nike’s VaporFly and AlphaFly lineups led the carbon plate revolution so thoroughly that some athletes sponsored by rival brands were blocking out the logo and wearing it anyway.
However, when the barrier finally came down in open competition, the man who broke it was wearing Adidas. In a rare reference to a competitor, Nike posted a message on its Instagram account after the race, acknowledging Sawi’s achievement without mentioning his name directly.
The issue of shoe technology does not diminish human achievement. Every era of sports has its advances: fiberglass poles, clapping sleds, full-body swimsuits. What Sawi did still requires Sawi. But the Adizero Evo 3’s weight and mechanical properties are part of the story, just as Kiptum’s Nike AlphaFly 3 was part of his 2:00:35 in Chicago.
There is another important layer to this story, especially in a sport scarred by doping scandals.
The Kenyan marathon has been hit hard in recent years. Ruth Chepnjitich, the 2024 women’s Chicago Marathon champion who ran a world record of 2:09:56, received a three-year doping ban in 2025. The pattern of fast times that followed the ban has eroded confidence in the sport.
Sawe’s response was unusual: he volunteered to undergo an enhanced, unannounced out-of-competition drug test by the Athletics Integrity Unit. In the lead-up to the 2025 Berlin Marathon alone, he underwent 25 tests, believed to be one of the most comprehensive voluntary testing protocols ever undertaken by any marathon runner. Its sponsor, Adidas, covers the cost, which is said to be about $50,000 a year. He passed every test.
It doesn’t silence all the skeptics. Nothing happens at all. But it is a statement of intent that goes far beyond what is required, and places the burden of evidence on anyone who wants to question the performance.
On the women’s side, today is again Tigist Assefa.
The Ethiopian defended her title in London with a time of 2:15:41, lowering the only women’s world record of 2:15:50, which she set in London the previous year. She edged out Helen O’Berry, a two-time Boston and New York Marathon champion, and Joycelyn Jepkosgei, who was the world’s fastest marathon runner in 2025 with a time of 2:14:00 in Valencia.
The finish was decided in the final 400 metres, where Assefa’s speed proved decisive, opening a gap of 12 seconds on Obiri and another two seconds on Jepkosgei.
At a press conference the next day, Assefa was characteristically direct. She said she realized the record was possible after the first five kilometres, when the pace was fast, but she felt comfortable. She attributed her success to hard work and said there is no secret to that.
It also acknowledged the broader significance of the day. “Obviously when we think about history, we think a lot about Sebastian’s achievement,” she said. “So I think what it says about running is that anything is possible.”
It’s worth remembering what two hours actually means in a marathon.
Running 26.2 miles in less than 120 minutes requires maintaining an average pace of about 4:34 per mile, or 2:50 per kilometer, for the entire distance. That’s faster than most recreational runners can run a mile. Sao maintained that pace, and sometimes exceeded it significantly, for nearly two hours without stopping.
The world record when Nike launched Project Breaking 2 in 2016 was 2:02:57, which was held by Dennis Kimetto. In a decade, the record has fallen by three and a half minutes, an extraordinary pressure in a field where improvements are usually measured in seconds.
It is impossible to predict whether the record will continue to decline at this rate. What seems certain is that what Sawi 1:59:30 said will not be the final word. Kegelsha, 28, has decades of competitive marathoning ahead of him. Kiplimo, the half marathon world record holder, is 25 years old. The depth of talent in East African long-distance running suggests that under two minutes will become, like the four-minute distance before it, a mark regularly crossed by exceptional athletes rather than a ceiling.
For now, the record belongs to a quiet man from Barsomby who didn’t seek fame, took more drug tests than anyone asked of him, and ran the final two kilometers of the marathon at a pace that defied his physiology.
Sawi ate two slices of bread with honey and tea for breakfast on Sunday morning. The two-hour barrier was not on his mind.
Then he passed through it anyway.
