By Matthias Henkert · Runner, road cyclist and developer of WattRun · Last reviewed
Quick Answer: The Records and Their Pace
All records are as of October 2026. The table below covers every benchmark discussed in this article. Paces are rounded to the nearest second from the finish time (42.195 km).
| Record | Athlete | Race | Time | Pace/mi | Pace/km |
|---|---|---|---|---|---|
| Men’s WR | Sabastian Sawe | London 2026 | 1:59:30 | 4:33 | 2:50 |
| Previous men’s WR | Kelvin Kiptum | Chicago 2023 | 2:00:35 | 4:36 | 2:51 |
| Women’s WR (mixed race) | Ruth Chepngetich | Chicago 2024 | 2:09:56 | 4:57 | 3:05 |
| Women-only WR | Tigst Assefa | London 2026 | 2:15:41 | 5:11 | 3:13 |
| Sub-2 (unofficial) | Eliud Kipchoge | Vienna 2019 | 1:59:40 | 4:34 | 2:50 |
The official marathon world record pace for men is 4:33 per mile. For women it’s 4:57 per mile. These numbers become even more remarkable when you put them next to everyday running experience.
How Fast Is World Record Pace, Really?
Marathon world record pace—4:33 per mile for men—is a speed most recreational runners can’t sustain for a single minute, let alone 26.2 miles.
To put it in concrete terms:
- Twice the speed of a typical recreational finisher. A runner completing a marathon in 4:30 holds roughly 10:18 per mile. World record pace is more than 2.2 times faster.
- Faster than many people sprint. A 4:33/mi effort corresponds to running 100 meters in about 17 seconds. Elite sprinters run 100m in 10–12 seconds, so Sawe’s marathon pace sits in the range many club runners can only hold for a few seconds of all-out effort.
- No meaningful fade. The frightening detail isn’t just the pace—it’s the consistency. The splits across marathon splits by mile for top WR efforts show almost metronomic evenness, with minor negative splits in the second half.
The women’s record pace of 4:57/mi is equally staggering. Ruth Chepngetich averaged just under five minutes per mile for the entire race.
The Men’s Record: Sabastian Sawe’s 1:59:30
On April 26, 2026, Sabastian Sawe of Kenya won the London Marathon in 1:59:30, taking 65 seconds off Kelvin Kiptum’s 2:00:35. World Athletics ratified the time in July 2026 and called Sawe the first man to break two hours in a record-eligible marathon.
- Pace: 4:33 per mile / 2:50 per kilometer
- Context: Unlike Kipchoge’s 1:59:40 in Vienna (see below), Sawe’s run came in an open race under standard competition rules, which is why it counts as a world record.
The Previous Men’s Record: Kelvin Kiptum’s 2:00:35
On October 8, 2023, Kelvin Kiptum of Kenya crossed the finish line at the Bank of America Chicago Marathon in 2:00:35, shattering Eliud Kipchoge’s previous record of 2:01:09 by 34 seconds.
Key details of Kiptum’s run:
- Pace: 4:36 per mile / 2:51 per kilometer
- Splits: Kiptum ran the first half in 1:00:48 and the second half in 59:47—a 61-second negative split.
- Conditions: Cool autumn morning in Chicago, a notoriously fast course with minimal elevation change.
- Coaching: Coached by Gervais Hakizimana, Kiptum was only 23 years old at the time, making the performance even more extraordinary.
Tragically, Kiptum passed away in a road accident in February 2024. His 2:00:35 stood as the world record until Sawe’s 1:59:30 in London in April 2026.

The Women’s Records
Ruth Chepngetich — 2:09:56 (Women’s Outright WR)
On October 13, 2024, Ruth Chepngetich of Kenya set the women’s marathon world record at the same Chicago course that witnessed Kiptum’s breakthrough a year earlier. Her time of 2:09:56 took 1 minute 57 seconds off the previous record (Tigst Assefa’s 2:11:53 from Berlin 2023).
- Pace: 4:57 per mile / 3:05 per kilometer
- First half: Chepngetich went through halfway in 1:04:16, an aggressive front-loading strategy that paid off.
- Significance: She became the first woman to break 2:10 in the marathon, a milestone that had seemed distant for years.
- Doping case: In July 2025 the Athletics Integrity Unit (AIU) provisionally suspended Chepngetich after a sample from March 14, 2025 tested positive for hydrochlorothiazide (HCTZ), a banned diuretic. In October 2025 the AIU banned her for three years, backdated to April 19, 2025. The disqualification covers results from March 14, 2025 onward, so the 2024 Chicago record was not annulled and remains the ratified world record.
Tigst Assefa — 2:15:41 (Women-Only WR)
World Athletics maintains a separate “women-only” category for races where no male runners or male pacers are present. The women-only world record (as of October 2026) belongs to Tigst Assefa of Ethiopia, who ran 2:15:41 at the London Marathon on April 26, 2026, nine seconds faster than her own previous women-only record of 2:15:50 (London 2025). Peres Jepchirchir’s 2:16:16 (London 2024) held the mark before that.
- Pace: 5:11 per mile / 3:13 per kilometer
- Context: Women-only records matter because mixed-sex races allow women to draft behind or be paced by male runners, which can provide a measurable aerobic advantage over a solo or women-only field.
Both records underline that women’s marathon running is in a golden era, with times improving dramatically in a short window.
The Sub-2 Barrier
The sub-2-hour marathon is the “four-minute mile” of the modern era—a barrier that captured the world’s imagination long before it fell.
Eliud Kipchoge ran 1:59:40 at the INEOS 1:59 Challenge in Vienna on October 12, 2019. His average pace was approximately 4:34 per mile (2:50/km)—faster than Kiptum’s 2:00:35, but 10 seconds slower than Sawe’s 1:59:30 from London 2026, the first sub-2 marathon to count as a world record.
Why It Doesn’t Count
Despite being a breathtaking athletic achievement, Kipchoge’s 1:59:40 is not recognized as an official world record by World Athletics. The reasons:
- Rotating pacers. A team of 41 elite runners took turns forming a precision aerodynamic formation around Kipchoge. World Athletics requires pacers to start the race and not be replaced mid-event.
- No open competition. The event was a time trial, not an open race. Official records must be set in competition open to any eligible athlete.
- Controlled fluid delivery. Drinks were handed to Kipchoge by a cyclist riding alongside him, rather than from fixed aid stations as rules require.
The INEOS event was designed to answer a scientific question—can a human run 26.2 miles in under two hours?—rather than to set a record. On that question, Kipchoge delivered an unambiguous yes. The official men’s world record is Sawe’s 1:59:30.
World Record Pace vs Your Pace
Understanding where world-record pace sits relative to recreational runners gives context that raw numbers alone can’t provide.
| Finish Time | Pace/mi | vs. Men’s WR Pace |
|---|---|---|
| 1:59:30 (WR) | 4:33 | — |
| 2:30:00 | 5:43 | +1:10/mi |
| 3:00:00 | 6:52 | +2:19/mi |
| 3:30:00 | 8:01 | +3:28/mi |
| 4:00:00 | 9:09 | +4:36/mi |
| 4:30:00 | 10:18 | +5:45/mi |
| 5:00:00 | 11:27 | +6:54/mi |
A runner finishing in 4:30—a common recreational result—takes about 2.26 times as long as the world record. Even a very solid 3:00 finisher is running at 6:52/mi, 2:19 per mile slower than Sawe.

As of October 2026, Sabastian Sawe of Kenya holds the men’s marathon world record with 1:59:30 (London, 2026), ratified by World Athletics in July 2026; it replaced Kelvin Kiptum’s 2:00:35 (Chicago, 2023). Ruth Chepngetich of Kenya holds the women’s outright world record with 2:09:56 (Chicago, 2024). Tigst Assefa of Ethiopia holds the women-only record with 2:15:41 (London, 2026).
What is the women’s marathon world record?
The women’s marathon world record (as of October 2026) is 2:09:56, set by Ruth Chepngetich at the 2024 Chicago Marathon. That’s a pace of 4:57 per mile (3:05/km). Chepngetich was banned for three years in October 2025 for a doping violation from March 2025; results before March 14, 2025, including the record, were not annulled. The women-only world record—set in a race without male pacers—is 2:15:41, held by Tigst Assefa from the 2026 London Marathon.
Has anyone run a sub-2-hour marathon?
Yes. Eliud Kipchoge ran 1:59:40 at the INEOS 1:59 Challenge in Vienna in 2019, becoming the first human to cover the marathon distance in under two hours. That run does not count as an official world record because it used rotating pacers, controlled fluid delivery, and was not an open competition as required by World Athletics rules. Sabastian Sawe became the first to do it in a record-eligible race, running 1:59:30 at the 2026 London Marathon.
How fast is world record pace per mile?
The men’s marathon world record pace is 4:33 per mile. Eliud Kipchoge’s unofficial sub-2 run averaged approximately 4:34 per mile. The women’s record pace is 4:57 per mile. These figures are roughly equivalent to running each mile at a speed most club runners can only sustain for 200–400 meters.
Why doesn’t Kipchoge’s 1:59:40 count as a world record?
World Athletics disqualified the INEOS 1:59 Challenge result because it violated three key rules: (1) pacers rotated in shifts rather than starting and finishing the race, (2) the event was a closed time trial rather than open competition, and (3) drinks were delivered by a cyclist rather than from fixed aid stations. The run stands as a historic human achievement—but not an official world record.
