The London Marathon has long been one of the fastest races on the global calendar. But the 2026 edition, on April 26, is something different. Four of the six fastest women in marathon history will be on the same start line. The defending champion himself predicts a course record will be needed to retain his title. That doesn't happen often.
Key Takeaways
- The 2026 London Marathon elite field is billed as the fastest in history
- Multiple sub-2:05 runners are lined up for the men's race
- The London Marathon is one of the 6 World Marathon Majors
The Women's Field: A Historic Convergence
Tigst Assefa, the world record holder at 2:11:53 set in Berlin in 2023, will be there. Alongside her: Sifan Hassan, one of the most versatile athletes in the history of distance running. Then Peres Jepchirchir, Olympic champion in Tokyo and Paris. And Joyciline Jepkosgei, whose 2:13:20 personal best ranks her among the all-time greats.
No other marathon has assembled this level of depth in the women's field. The women's course record at London is 2:16:16 — it'll be under serious pressure in April. London's typical April conditions (10-15°C) favor fast times.
The Men's Race: The Defending Champion Under Maximum Pressure
Sabastian Sawe won the 2025 edition in 2:02:27. He's back to defend his title, and he knows what's coming. Against him: Tamirat Tola, Paris 2024 Olympic champion; Joshua Cheptegei, world record holder at 5,000m and 10,000m with a 2:04:52 marathon personal best; and Yomif Kejelcha, one of the best middle-distance runners of his generation transitioning to the marathon.
Sawe himself said it would likely take a course record to keep his title. The men's course record at London is 2:01:25, set by Kelvin Kiptum in 2023. That target is within reach for this field — conditions allowing.
Emile Cairess and the British Records
In a field this loaded, Emile Cairess is running for a national target. The British marathon record belongs to Sir Mo Farah at 2:05:11, set in London in 2018. Cairess's personal best is 2:05:36 — 25 seconds off. With this field setting a hard pace from the start, the conditions are there for a serious attempt.
Why This Edition Matters More Than Usual
The Paris 2024 Olympics reshuffled the marathon hierarchy. Tola won gold, Hassan took bronze, Jepchirchir silver in the women's race. But the road marathon and the Olympic marathon operate on different dynamics. London 2026 is the first major head-to-head since Paris — a direct rematch between the same athletes on a different format.

For spectators on the course or at home, this is one of the most compelling lineups in years. April 26 can't come soon enough.
