Beyond 2:10: what is the women’s marathon chasing now?

The next big question in the women’s marathon is no longer whether someone can finish inside two hours and ten minutes. Ruth Chepngetich broke that barrier with 2:09:56 in Chicago in October 2024, while Ethiopia’s Fotyen Tesfay ran 2:10:51 on her marathon debut in Barcelona in March 2026. On Sunday, Tigst Assefa returns to Berlin, the course where her 2:11:53 in 2023 opened a new era. Taken together, the three performances suggest that the once-distant level is no longer tied to one exceptional day: there is now more than one route into the 2:10 range.

This is an original BSR analysis, not an interview or an on-site report. Its fresh starting point is World Athletics’ 24 September Berlin preview; the record data come from the federation’s official lists and ratification notices.

Berlin already rewrote the standard once

Assefa’s 2:11:53 in 2023 was shocking because it cut more than two minutes from Brigid Kosgei’s world record. The contemporary World Athletics report documented more than a course record: it was one of the largest jumps in the history of the women’s marathon. Berlin’s flat route, controlled pacing and Assefa’s track-bred speed aligned.

The record has since moved on. Chepngetich’s 2:09:56 remains the official world record, and Tesfay’s 2:10:51 from 2026 now ranks second on the World Athletics all-time list. Assefa’s Berlin mark is therefore third, but it has not lost importance. It became a bridge between two eras: proof that sub-2:12 was not theoretical, followed by evidence that the level could be repeated and extended.

Two records, two race dynamics

Women’s marathon records require a distinction between two categories. The mixed-race world record is set when men and women compete in the same event, while the women-only record reflects a different race dynamic. Assefa lowered the women-only record to 2:15:50 in London in 2025 and then to 2:15:41 in 2026; World Athletics’ September ratification made the latter official.

The two figures should not be used against each other. Packs form differently, pacemakers can have different roles, and the leaders face different decisions. The 2:09:56 mark shows how far the absolute limit has moved in a fast mixed race. The 2:15:41 mark shows what can be sustained when the elite women run their own contest. Both describe the same broader change: the women’s marathon has become faster, deeper and tactically richer.

The record chase is no longer about one name

The real change may be the density of the all-time list rather than the identity of the record-holder. Tesfay ran 2:10:51 at the 2026 Barcelona Marathon on her debut at the distance. According to the World Athletics report, she immediately moved to second all time. One remarkable debut does not guarantee long-term dominance, but it does show that the next record challenge may not come only from the same two or three established major-marathon champions.

Berlin’s depth makes the same point. The official preview lists seven women with personal bests under 2:20. Defending champion Rosemary Wanjiru, last year’s runner-up Dera Dida and Assefa on one start line promise more than a fast time: they create a race in which pacing mistakes will be punished. Anyone chasing record tempo too early will not have passive extras running behind her.

What would another major leap require?

A marathon record is not a laboratory result. Across 42.195 kilometres, weather, wind, pacemaking, fuelling and the rhythm of the course matter as much as fitness. Berlin is known as a fast course, but a fast course does not guarantee a fast race. The key question is whether the lead group reaches the 30–35km segment through even splits, because that is where the cost of an overambitious opening usually appears.

Assefa’s position is especially compelling. Her 2:11:53 personal best proves she can sustain extreme speed, and World Athletics reports that she wants a new best in Berlin. She would need to improve by more than a minute to beat Tesfay’s 2:10:51, and by almost two minutes to challenge Chepngetich’s 2:09:56 world record. The gap looks small on paper, but it is a long sequence of seconds per kilometre. There is no single point at which it can simply be won back.

That is why the defining moment of a record attempt is not a spectacular opening 5km. Success is more likely to be built from patience and precision: controlled pace, flawless fuelling and reserves for the final seven kilometres. Modern shoes and professional preparation are part of the picture, but they do not alone explain why an athlete can still race late while her body is operating close to its limit.

The return carries more than a time target

For Assefa, Berlin is not merely a favourable course. It is the place where she became a global marathon star. That is both an advantage and a burden. She knows the route’s rhythm, its long straights and the moment when the finish becomes tangible near the Brandenburg Gate. Yet every split will be compared with her 2023 record, even though two women have since moved ahead of her on the all-time list.

A new personal best would therefore be more than a statistical position. It would show that Assefa can adapt to an accelerating discipline three years after her first Berlin breakthrough. That matters especially in the marathon: training cycles are long and opportunities for a true maximum effort are limited. One missed drink, an infection or an overfast first half can rewrite months of work.

Self-control may therefore be as valuable as courage on Sunday. Wanjiru, the defending champion, knows how to win in Berlin; Dida, last year’s runner-up, knows the decisions demanded by the late stages of the course. Assefa arrives with the fastest personal history among them, but she is not racing the clock alone. Every fast kilometre is also a tactical message: who finds the pace comfortable, who is saving energy and who is trying to break the group before the final push.

That is what makes this record era compelling. The clock displays figures that looked futuristic only a few years ago, but the foundation of the race remains unchanged: people make decisions while becoming exhausted. A record becomes a story only when someone wins that sequence of decisions behind the numbers.

The question after 2:10

Breaking the 2:10 barrier can produce a new, overly simple narrative: that every major marathon should now yield a world record. The value of a race, however, is not contained only in the clock. A 2:14 victory in wind, heat or a tactically fractured contest may be better than the number appears. Record pace and winning pace are not always the same thing.

Two stories therefore deserve attention on Sunday. One belongs to the numbers: how long can Assefa, Wanjiru and Dida remain close to 2:10 pace? The other belongs to the race itself: who can decide the contest after the pacemakers step aside, the group breaks and the prepared script ends?

The past three years of women’s marathoning have not established a final frontier; they have removed old certainties. Assefa’s 2:11:53 in Berlin, Chepngetich’s 2:09:56 world record and Tesfay’s 2:10:51 debut are three different stories. Together they say the same thing: the record-level field is widening, the pace has accelerated, and the next great time may not be an inexplicable miracle. The surprise may instead be who produces it, and from what kind of race.
