The Last Barrier | by RT Johno

On a grey London morning, Sabastian Sawe ran into the realm of the impossible and made it look like inevitability

For decades, the two hour marathon existed in the same mental space as the four minute mile once did: a number so round, so clean, so close to what the best humans could do, that it became less a time and more a philosophical boundary. Could a person 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 Kimaru Sawe answered both questions in the same breath. He crossed the finish line on The Mall in 1 hour, 59 minutes and 30 seconds. No asterisks. No controlled course. No rotating pacemakers shielding him from the wind. Just a bib number, a World Marathon Major, a drug tested field, and the best runners on the planet chasing him.

The previous world record of 2:00:35, set by the late Kelvin Kiptum at the 2023 Chicago Marathon, did not just fall. It was obliterated by 65 seconds.

And Sawe was not alone in breaking through. Ethiopia’s Yomif Kejelcha, running his first ever marathon, finished 11 seconds behind him in 1:59:41. Uganda’s Jacob Kiplimo was third in 2:00:28, himself inside Kiptum’s old record. Three men under the previous world record in a single race. Two of them under two hours.

The four minute mile fell in 1954. It took 46 days for a second man to break it, and 16 more followed within two years. The two hour marathon lasted approximately the length of a deep breath between the first and second man through the door. Walls, it turns out, fall in clusters.

Sawe was born and raised in the Rift Valley, in a village called Barsombe in Uasin Gishu County. The region is the most prolific incubator of 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 high altitude farmland in western Kenya.

But Sawe was, by the standards of Kenyan marathon royalty, a late bloomer. Kiptum was running 2:01 in his debut at 22. Kipchoge was world 5,000 metre champion as a teenager. Sawe spent most of his twenties on the track and on the half marathon circuit, building a career that was impressive but not yet historic. He set a course record at the Rome Ostia Half Marathon in 2022, won the World Road Running Championships half marathon in 2023, and was part of Kenya’s gold medal team at the World Cross Country Championships.

His marathon debut came in December 2024 at Valencia. He won in 2:02:05, one of the fastest debut times in history. He followed it with a victory in London in April 2025 (2:02:27) and then Berlin the following September (2:02:16, in warm conditions that almost certainly masked faster potential). Four marathons, four victories, and a quiet trajectory that pointed toward something larger.

His coach, the Italian trainer Claudio Berardelli, has described Sawe as calm, analytical, and highly focused. Fellow athletes and training partners paint a similar picture: a man who does not waste words, does not court publicity, and does not let the noise of the sport pull him away from the 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 hung over the London Marathon long before the gun fired.

Kiptum set the course record at London in 2023 with a 2:01:25, then ran 2:00:35 in Chicago that October to claim the world record. He was 24, clearly ascending, and had announced his intention to become the first man to break two hours in a sanctioned race at the Rotterdam Marathon in April 2024.

He never made it. On the night of 11 February 2024, Kiptum lost control of his car on the Eldoret Kaptagat road in western Kenya. He and his Rwandan coach, Gervais Hakizimana, were killed instantly. A third passenger survived with injuries. His world record had been officially ratified by World Athletics just five days earlier.

The running world mourned not just the man, but the future he represented. Kiptum was, almost everyone agreed, the one most likely to break two hours first. His death left an open question: who would carry the torch he had been denied the chance to hold?

Sawe never claimed that mantle publicly. In the days before London 2026, he downplayed world record talk, telling reporters that Kiptum’s course record of 2:01:25 was his target. His coach Berardelli revealed that Sawe had been injured through the autumn and had only resumed proper training in January. By February, the stated goal was simply to defend his London title.

The conditions on Sunday were near perfect: overcast, cool, minimal wind. The pacers were tasked with delivering a halfway split of 60:30, and they did their job. Sawe and five others passed the 13.1 mile mark in 60:29.

From there, Sawe began to do what he does best: run away from people.

As the pacers dropped off, Sawe and Kejelcha emerged as the two strongest runners in the field. Kiplimo held on gamely but could not match their pace. The race became a private war between two men: one a four time marathon winner chasing history, the other a debutant with a former half marathon world record on his resume and apparently no concept of what a sensible first marathon should look like.

Sawe’s closing speed was breathtaking. His final 2.195 kilometres, from the 40 kilometre mark to the finish, was covered in 5 minutes and 51 seconds, an average pace of approximately 4:17 per mile, which equates to a hypothetical marathon pace of around 1:52. That is the fastest anyone has ever covered that segment of the marathon distance.

After mile 25, Kejelcha finally yielded. Sawe powered down The Mall with his form looking as crisp as it had at the start. He saw the clock. He punched the air.

“I’m so happy,” he told the BBC. “Approaching the end of the race, I was feeling strong. The Ethiopian was so competitive. I think he was the one who helped a lot. And finally reaching the finishing line, I saw the time, and I was so excited.”

Kipchoge, the man who ran 1:59:40 in the Ineos 1:59 Challenge in Vienna in 2019 (an unofficial, non record eligible performance with rotating pacers and a pace car), posted his congratulations from his own social media account. He called it a historic day and said it proved that humanity was “just at the beginning of what is possible.”

The conversation about shoes cannot be avoided.

Sawe wore the Adidas Adizero Adios Pro Evo 3, a shoe that was being used for the first time in a marathon in London. It weighs 97 grams (3.4 ounces) in a men’s size 9, roughly 30 per cent lighter than its predecessor, with a 39 millimetre stack height sitting one millimetre below the World Athletics legal limit. Four of the top five male finishers wore Adidas.

It is an irony worth sitting with. Nike launched the Breaking 2 project in 2016 with the explicit goal of engineering a sub two hour marathon. Kipchoge ran 2:00:25 in that controlled attempt in 2017, then broke through with 1:59:40 in Vienna in 2019, both in Nike prototypes. Nike’s VaporFly and AlphaFly range drove the carbon plate revolution so completely that some sponsored athletes from rival brands were reportedly blacking out the swoosh and wearing them anyway.

And yet, when the barrier finally fell in open competition, the man who broke it was wearing Adidas. In a rare nod to a rival, Nike posted a message on its Instagram account after the race, acknowledging Sawe’s achievement without naming him directly.

The shoe technology question does not diminish the human achievement. Every era of sport has its advances: fibreglass poles, clap skates, full body swimsuits. What Sawe did still required Sawe. 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 layer to this story that matters, particularly in a sport wounded by doping scandals.

Kenyan marathon running has been hit hard in recent years. Ruth Chepngetich, the 2024 Chicago Marathon women’s champion who ran a world record 2:09:56, received a three year ban for doping in 2025. The pattern of fast times followed by bans has eroded trust in the sport.

Sawe’s response was unusual: he volunteered for enhanced, unannounced out of competition drug testing by the Athletics Integrity Unit. In the buildup to the 2025 Berlin Marathon alone, he underwent 25 tests, believed to be one of the most extensive voluntary testing protocols any marathoner has ever submitted to. His sponsor, Adidas, covers the cost, reportedly around $50,000 per year. He has passed every test.

It does not silence all sceptics. Nothing ever does. But it is a statement of intent that goes well beyond what is required, and it places the burden of evidence on anyone who wants to question the performance.

On the women’s side, the day belonged once again to Tigst Assefa.

The Ethiopian defended her London title in 2:15:41, lowering her own women’s only world record of 2:15:50 set in London the previous year. She held off Hellen Obiri, the two time Boston and New York City Marathon champion, and Joyciline Jepkosgei, who had been the world’s fastest female marathoner in 2025 with a 2:14:00 in Valencia.

The finish was decided in the final 400 metres, where Assefa’s track speed proved decisive, opening a 12 second gap on Obiri and another two seconds on Jepkosgei.

At a press conference the following day, Assefa was characteristically direct. She said she knew 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 was no secret to it.

She also acknowledged the broader significance of the day. “Obviously when we’re thinking about the history, we’re thinking very much about Sabastian’s achievement,” she said. “So I think what it says about running is that anything is possible.”

It is worth remembering what two hours actually means in a marathon.

To run 26.2 miles in under 120 minutes requires sustaining an average pace of approximately 4:34 per mile, or 2:50 per kilometre, for the entire distance. That is faster than most recreational runners can sprint a single mile. Sawe held that pace, and at times exceeded it considerably, for nearly two hours without stopping.

The world record when Nike launched the Breaking 2 project in 2016 was 2:02:57, held by Dennis Kimetto. In a decade, the record dropped by three and a half minutes, an extraordinary compression in a discipline where improvements are typically measured in seconds.

Whether the record will continue to fall at that rate is impossible to predict. What seems certain is that Sawe’s 1:59:30 will not be the last word. Kejelcha, at 28, has decades of competitive marathon running ahead of him. Kiplimo, the half marathon world record holder, is 25. The depth of talent in East African distance running suggests that sub two will become, like the four minute mile before it, a marker that exceptional athletes clear regularly rather than a ceiling.

For now, the record belongs to a quiet man from Barsombe who did not seek fame, submitted to more drug tests than anyone asked him to, and ran the last two kilometres of a marathon at a pace that defied physiology.

Sawe 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 ran through it anyway.
