The marathon entered a new era on Sunday at the 2026 London Marathon. For the first time in history, two men—Kenya’s Sabastian Sawe and Ethiopia’s Yomif Kejelcha—finished a record-eligible race in under two hours. Sawe’s 1:59:30 not only rewrote the record books but also marked the first time the two-hour barrier had been broken in a race that counted toward official world records.

“Today is a historical day for marathon running,” Eliud Kipchoge, the first man to run a sub-two-hour marathon (though not in a record-eligible race), wrote on Instagram after the race. “We are just at the beginning.”

How the Impossible Became Reality

The London Marathon has long been a stage for history. But Sunday’s performances transcended even the sport’s wildest expectations. Sawe, a 28-year-old Kenyan, didn’t just break the two-hour mark—he obliterated it, finishing in 1:59:30. That time sliced more than a minute off the previous world record of 2:00:35, set by the late Kelvin Kiptum at the 2023 Chicago Marathon. Kiptum, who died in a car accident in February 2024 at age 24, held the record as his final legacy.

Kejelcha, a 26-year-old Ethiopian making his marathon debut, crossed the line just 11 seconds later in 1:59:41. His time set an Ethiopian national record and made him the fastest marathon debutant in history. The two men’s achievements were so dominant that the next finisher, Kenya’s Alexander Mutiso, finished in 2:03:12—nearly four minutes behind.

The Women’s Race: A Historic Trifecta

While the men’s race stole the headlines, the women’s race delivered its own historic moment. Ethiopia’s Tigst Assefa, the 2023 Berlin Marathon champion, defended her London title and broke her own world record for a women-only field, finishing in 2:15:41. Kenya’s Hellen Obiri, in her London debut, set a personal best of 2:15:53, while Joyciline Jepkosgei rounded out the podium in 2:15:55. It was the first time three women had broken 2:16 in the same race.

Why This Race Matters

The two-hour marathon barrier has long been seen as the sport’s equivalent of the four-minute mile—a psychological and physiological limit that once seemed unbreakable. Kipchoge first broke it in 2019 at the INEOS 1:59 Challenge in Vienna, but that race, staged under controlled conditions with rotating pacemakers and a laser-guided light, did not qualify for official world record status. Sunday’s race, by contrast, was run under standard marathon conditions, making Sawe’s and Kejelcha’s times eligible for world records.

“This isn’t just about one race,” said Kipchoge in his post-race statement. “It’s about what the marathon can develop into. The barriers we thought were permanent are falling, and that’s exciting for everyone who loves this sport.”

The Science Behind the Speed

So how did Sawe and Kejelcha do it? The answer lies in a combination of factors: advances in training, nutrition, footwear technology, and race strategy.

• Training: Modern marathon training has evolved to include high-altitude camps, data-driven pacing strategies, and recovery techniques like cryotherapy and hyperbaric chambers. Sawe, for example, trained at Kenya’s high-altitude Rift Valley, a region known for producing elite distance runners.
• Footwear: The introduction of carbon-plated, energy-returning shoes has revolutionized the sport. While some purists argue that these shoes provide an unfair advantage, they have undeniably contributed to faster times across the board. Sawe and Kejelcha both wore the latest iterations of these shoes during the race.
• Race Strategy: The London Marathon’s flat, fast course is designed for record-breaking performances. But even on a perfect course, executing a sub-two-hour marathon requires near-perfect pacing. Sawe and Kejelcha ran the first half in 59:45, a pace that would have seemed suicidal just a decade ago. Their ability to maintain that speed through the second half was a testament to their conditioning and mental toughness.
• Nutrition: Elite marathoners now rely on precise fueling strategies, consuming carbohydrates at regular intervals to maintain energy levels. Sawe, for instance, took in 60 grams of carbohydrates per hour during the race, a regimen that helped him avoid the dreaded “wall” that derails so many runners.

What’s Next for the Marathon?

Sawe’s and Kejelcha’s performances raise an obvious question: How much faster can the marathon get? Kipchoge’s 2019 sub-two-hour run suggested that the barrier was breakable, but few expected it to happen in a record-eligible race so soon. Now that the two-hour mark has been conquered, the next frontier is likely the 1:59:00 barrier—or even lower.

For now, though, the focus is on celebrating what happened in London. “What we have is a moment for the history books,” said World Athletics President Sebastian Coe in a statement. “It’s a reminder of what human beings are capable of when they push the limits of what’s possible.”

Key Takeaways

• First sub-two-hour marathon in a record-eligible race: Sabastian Sawe (1:59:30) and Yomif Kejelcha (1:59:41) made history at the 2026 London Marathon.
• Women’s race delivers historic trifecta: Tigst Assefa (2:15:41), Hellen Obiri (2:15:53), and Joyciline Jepkosgei (2:15:55) all broke 2:16.
• Advances in training, footwear, and nutrition played a key role: These factors combined to make the sub-two-hour marathon a reality.
• Eliud Kipchoge’s legacy: The four-time London Marathon champion’s 2019 sub-two-hour run paved the way for Sunday’s performances.
• The next frontier: With the two-hour barrier broken, the focus now shifts to how much faster the marathon can get.

What to Watch Next

The next major marathon on the calendar is the Berlin Marathon on September 28, 2026. Given the breakthroughs in London, all eyes will be on whether another athlete can push the boundaries even further. Sawe and Kejelcha will likely be among the favorites, but the sport’s rapid evolution means that new contenders could emerge at any time.

For now, though, the marathon world is still processing what happened in London. As Kipchoge set it: “We are just at the beginning.”
