Marathon world record evolution (2026)

Last year I wrote an update of the all-time men’s marathon best times and the world record evolution (post here, following an older one from 2014, ahead of running that year’s Rotterdam marathon). This is a new update including 2026 best time as this has been an extraordinary year: the world record has been beaten and the two hours barrier has been broken in an official race for the first time in history. The 2026 version of the post includes all marathon times below 2h08′ up to and including today’s New York marathon.

As in the previous posts, I use the website “Track and Field all-time Performances” (maintained since years ago by Peter Larsson). As Larsson has not updated his marathon times list since mid August, this time I completed the dataset with World Athletics all-time toplists (which added 86 times from the races between late September and late October) and with today’s New York marathon results (from LetsRun, still provisional at the time of writing, as NYRR has not yet published the official ones).

With the data of all-time best men’s marathon I plotted the chart below with the best 2,239 times, i.e., all those below 2h08′, and their dates, highlighting marathon times by Haile Gebrselassie, Wilson Kipsang, Eliud Kipchoge, Kenenisa Bekele, Kelvin Kiptum, Sabastian Sawe, Yomif Kejelcha, Jacob Kiplimo and Amos Kipruto.

All-time best marathon results, 2,239 times below 2h08

Some stats in relation to those 2,239 times under 2h08′ (they were 1,903 when I reviewed them in September 2025; 249 of them have been achieved in 2026 alone, more than in any previous year!):

  • Countries of which athletes achieved most such times: Kenya 959 times or 42.8%, Ethiopia 666 times or 29.7%, Japan 138 (6.2%), Morocco 51 (2.3%), Eritrea 51 (2.3%), USA 34 (1.5%), Uganda 27 (1.2%), Spain 27 (1.2%), Israel 26 (1.2%). Those are the top 9 countries, there are another 35 from which athletes have run below 2h08′ (for a total of 44 countries).
  • There are 872 athletes that have run below 2h08′. The individuals who have done so more often: Eliud Kipchoge 18 times (he still runs marathons, he even won the Melbourne marathon 3 weeks ago in 2h09 at 41 years old!), Sisay Lemma 17, Tamirat Tola 16, Amos Kipruto 15, Tsegay Kebede 15, Benson Kipruto 14, Abel Kirui 13, Evans Chebet 12, Wilson Kipsang 12, Geoffrey Kamworor 12, Bernard Kiprop 12, Birhanu Legese 11, … Kenenisa Bekele 10, Haile Gebrselassie 10…

Now, if we raise the bar to see the times at or below 2h05′, we find 301 times (they were 231 a year ago):

  • Countries of which athletes achieved most such times: Kenya 135 times or 44.9%, Ethiopia 121 times or 40.2% (both combined 85.1%!), Uganda 7 (2.3%), Tanzania 7 (2.3%), Belgium 5 (1.7%), Germany 5 (1.7%). Those are the top 6 countries, there are another 15 from which athletes have run at or below 2h05′ (for a total of 21 countries, 5 more than last year).
  • There are 154 athletes that have run at or below 2h05′ (30 more than last year). The individuals who have done so more often: Eliud Kipchoge 14 times, Amos Kipruto 10, Tamirat Tola 10, Wilson Kipsang 8, Sisay Lemma 7, Birhanu Legese 6, Gabriel Geay 5, Alexander Mutiso 5, Leul Gebrselassie 5, Sabastian Sawe 4,  Kenenisa Bekele 4, and several other athletes with 4, and with 3 times including Kelvin Kiptum, Dennis Kimetto, Geoffrey Mutai and Haile Gebrselassie.
  • Which are the fastest marathons? The cities where most of those 301 times at or below 2h05′ have been achieved are: Berlin 41, Valencia 39, London 33, Amsterdam 28, Dubai 27, Chicago 24, Rotterdam 22, Tokyo 21. Those are the top 8 cities (accounting for 78% of those 301 times), there are other 17 cities where such fast times have been achieved.

Now let’s look at the evolution of the World Record since 1985 in this other chart:

World record evolution since 1985, ending with Sawe 1:59:30 in 2026

Some comments to the chart:

  • In the last 41 years, the record has been beaten 14 times.
  • The current world record was set by Sabastian Sawe in London on 26 April 2026 with 1h59’30”, at the age of 31. It is the first official time below 2 hours and it was ratified by World Athletics in July (Eliud Kipchoge had run 1:59:41 in Vienna in 2019, but that exhibition, with rotating pacemakers, was not record-eligible).
  • That London race was historic beyond the record: Yomif Kejelcha (1h59’41”) and Jacob Kiplimo (2h00’28”) also finished under the previous world record, with Amos Kipruto 4th in 2h01’39”, Tamirat Tola 5th in 2h02’59” and Deresa Geleta 6th in 2h03’23”.
  • Sawe took 1’05” off Kiptum’s record, which had lasted two years and a half. The biggest improvement of the record was still made by Eliud Kipchoge, who took 1’18” off Dennis Kimetto’s previous record in 2018.
  • The record that lasted the most was Dinsamo’s 2:06:50 in 1988, which took just over 10 years to be beaten by Ronaldo da Costa in 1998.
  • 3 athletes have set the world record twice: Khalid Khannouchi, Haile Gebrselassie and Eliud Kipchoge.
  • Geoffrey Mutai ran in 2h03’02” in Boston 2011 and this year John Kipkosgei won Boston in 2h01’52”; as Boston is a downhill point-to-point course, those times do not count for the record.
  • In the same day in London, Tigst Assefa set a women-only world record of 2h15’41” (improving her own mark from 2025), with Hellen Obiri (2h15’53”) and Joyciline Jepkosgei (2h15’55”) completing the first race ever with 3 women below 2h16′ (see World Athletics report and London Marathon).

Other remarkable marathon facts from 2026:

  • Amos Kipruto won Chicago in 2h01’09”, equalling to the second the world record that Kipchoge had set in Berlin 2022.
  • Guye Adola won Berlin in 2h02’50”, and Tamirat Tola won Beijing in 2h03’10”.
  • Eliud Kipchoge, close to turning 42, ran won Melbourne two weeks ago.
  • Today in New York, Andreas Almgren (the reigning world half marathon champion) won in his marathon debut with 2h06’01”; 13 men ran below 2h08′.

What is the best age to run marathons?

I plotted this other chart looking at the best 2,239 marathon times vs the age the runners had at the time of completing each of those races (for the 2,201 of them for which the sources include the full birth date).

Marathon times vs age

Most of the times below 2h08′ are achieved between 23 and 33 years old, and the very best ones are spread between 25 and 37, with the exceptions of the 3 marathons ran by Kelvin Kiptum, including his former world record at 23.9, Tadese Takele (2h03’24” at 21.1) and the 2h00’28” by Jacob Kiplimo at 25.4. Sawe’s world record, on the contrary, was set at 31.1. The youngest ever to run such a fast marathon was Tsegaye Mekonnen: 2h04’32” in Dubai 2014 at 18.6.

Another interesting chart to relate best times and age is the histogram below. In that one we can see that effectively most of the times below 2h08′ are achieved between 24 and 30 years old, and between 23 and 33 (both included) 79% of those times are achieved.

Histogram of marathon best times by age

Let’s see what Valencia brings in December with Yomif Kejelcha and John Korir on the roster.

Marathon world record evolution (2025)

Last time I checked all-time men’s best marathon times and the world record evolution was in 2014 ahead of running Rotterdam marathon (post back then). In this blog post I’m going to make an update, share some charts and review some statistics. For that purpose, I use the website “Track and Field all-time Performances” (maintained since years ago by Peter Larsson).

With the data of all-time best men’s marathon I plotted the chart below with the best 1,903 times, i.e., all those below 2h08′ and their dates, highlighting marathon times by Haile Gebrselassie, Wilson Kipsang, Eliud Kipchoge, Kenenisa Bekele and Kelvin Kiptum.

Some stats in relation to those 1,903 times under 2h08′:

  • Countries of which athletes achieved most such times: Kenya 853 times or 44.8%, Ethiopia 570 times or 30.0%, Japan 114 (6.0%), Morocco 44 (2.3%), Eritrea 41 (2.2%), Israel 20 (1.1%), France 20 (1.1%), Uganda 19 (1.0%). Those are the top 9 countries, there are another 34 from which athletes have run below 2h08′ (for a total of 43 countries).
  • There are 742 athletes that have run below 2h08′. The individuals who have done so more often: Eliud Kipchoge 18 times, Sisay Lemma 17, Tsegay Kebede 15, Tamirat Tola 13, Abel Kirui 13, Wilson Kipsang 12, Bernard Kiprop 12, Evans Chebet 12, Benson Kipruto 12, Laban Korir 11, Emmanuel Mutai 11, Amos Kipruto 11, Birhanu Legese 11, Kenenisa Bekele 10, Haile Gebrselassie 10, Leul Gebrselassie 10, Deso Gelmisa 10…

Now, if we raise the bar to see the times at or below 2h05′, we find 231 times:

  • Countries of which athletes achieved most such times: Kenya 108 times or 46.8%, Ethiopia 98 times or 42.4% (both combined 89.2%!), Tanzania 4 (1.7%), Belgium 4 (1.7%), Netherlands 3 (1.3%). Those are the top 5 countries, there are another 11 from which athletes have run at or below 2h05′ (for a total of 16 countries).
  • There are 124 athletes that have run at or below 2h05′. The individuals who have done so more often: Eliud Kipchoge 14 times, Tamirat Tola 8, Wilson Kipsang 8, Sisay Lemma 7, Amos Kipruto 6, Birhanu Legese 6, Leul Gebrselassie 5, three athletes with 4 times including Kenenisa Bekele, 14 athletes with 3 times including Kelvin Kiptum, Dennis Kimetto, Geoffrey Mutai and Haile Gebrselassie, 23 athletes with 2 times including Patrick Makau…
  • Which are the fastest marathons? The cities where most of those 231 times at or below 2h05′ have been achieved are: Berlin and Valencia with 35 each, London and Dubai with 27 each, Rotterdam 18, Amsterdam and Chicago with 15 each, Tokyo 14. Those are the top 8 cities (accounting for 81% of those 231 times), there are other 16 cities where such fast times have been achieved.

Now let’s look at the evolution of the World Record since 1985 in this other chart:

Some comments to the chart:

  • In the last 40 years, the record has been beaten 13 times.
  • The current world record was set by Kelvin Kiptum in Chicago in 2023 with 2h00’35” at the age of 23.9. He sadly passed away in a car crash a few months later. His career was very promising, having run only 3 marathons, all three in less than 12 months, all 3 below 2h02′. 3 of the best 7 times, 1 of the only 4 men having run below that mark.
  • The record that lasted the most was Dinsamo’s 2:06:50 in 1988, which took just over 10 years to be beaten by Ronaldo da Costa in 1998.
  • 3 athletes have set the world record twice: Khalid Khannouchi, Haile Gebrselassie and Eliud Kipchoge.
  • The biggest improvement of the record was made by Eliud Kipchoge who took 1’18” off Dennis Kimetto’s previous record.
  • Geoffrey Mutai ran in 2h03’02” before 3 world records set the bar below his time, however, as he achieved that in Boston 2011 (downhill and point to point race) it didn’t count for the record.

What is the best age to run marathons?

I plotted this other chart looking at the best 1,903 marathon times vs the age the runners had at the time of completing each of those races.

Most of the times below 2h08′ are achieved between 23 and 33 years old, but indeed most of the best ones are achieved between 28 and 39 years old, with the exception of the 3 marathons ran by Kelvin Kiptum, including his current world record.

Another interesting chart to relate best times and age is the histogram below. In that one we can see that effectively most of the times below 2h08′ are achieved between 24 and 30 years old, and between 23 and 33 (both included) 80% of those times are achieved.

Rotterdam Marathon preview

Next Sunday, April 13th, I will take part in the Rotterdam Marathon together with the usual suspects (Jaime, Serna and Manuel). I am arriving to this marathon a bit short of training as I already reflected at the time of running Blagnac’s half marathon about a month ago. I may have completed just about 2/3 of the training plan I followed, having run just about 500km in the 16 weeks preceding the marathon. Thus, in this preview instead of talking about how I arrive to it I wanted to focus on the front of the race.

Rotterdam marathon is one of the fastest marathons in the world nowadays. On top of that, I learnt a few weeks ago that Kenyan athlete Eliud Kipchoge will take part in it. Kipchoge has today the 7th best time (1) in the distance (2h4’5″), achieved in only his second attempt at a marathon, in Berlin on the 29th of September 2013, when Wilson Kipsang beat the World Record (2h3’23”). I then wondered whether on Sunday a new world record could be set.

To be clear, setting up an athletics record is not an easy feat. Especially not in a marathon. But taking that question as a departure point I deep dived a bit into the data in order to learn more about the race.

The last time the marathon WR record was set in Rotterdam was in 1988 (26 years ago), when Belayneh Densamo left it at 2:06:50. Since then the WR has been beaten 8 times; once in Chicago, once in London and 6 times in Berlin, among them the last 5 times (see here the progression). Thus, we could confidently say that Berlin is the fastest marathon nowadays.

I then made a comparison of those 4 fast marathons over the last 14 years (since 2000), to see which one was the fastest race each of those years. See the results in the table below:

World fastest marathons (2000-2014).

World fastest marathons (2000-2014).

In the table you may see that out of the 14 years Berlin was the fastest of the 4 marathons in 7 (50%), however Rotterdam was the fastest marathon in 4 of those years (with a best time of 2h4’27”). By average winning times it would came 3rd (with a 2h6’32”) just after Berlin and London.

A curiosity, only twice in the past 14 years has the same runner won both Rotterdam and Berlin marathons in the same natural year: Felix Limo (2004) and Patrick Makau (2010) (2), both times each runner made a faster time in Rotterdam.

My train of thought then suggested: you are only paying attention to the winners’ times, you should compare more times to sense the profile of the race. I then found the following terrific website with all time best performances in track and field (maintained by Peter Larsson). With that database the analysis was rather simple.

I focused on the top 100 all-time marathon best times, of those:

  1. Berlin: 15 of the 100 all-time best times were achieved in Berlin, with a top 5 average time of 2h3’53” and a top 10 average of 2h4’18”.
  2. Chicago: 13/100; 2h4’29” (top 5); 2h5’4″ (top 10).
  3. Dubai: 18/100; 2h4’39” (top 5); 2h4’46” (top 10).
  4. Rotterdam: 14/100; 2h4’40” (top 5); 2h5’54” (top 10).
  5. London: 14/100; 2h5’02” (top 5); 2h5’15” (top 10).

Taking into account the top 100 times, Rotterdam marathon falls to the 4th place, seeing the irruption of Dubai as one of the top marathons, with all those times achieved in the last 6 years (run since 2000).

I then went a further step and made the following graph taking into account the top 1,000 times achieved in the last 45 years and highlighted in red those achieved in Rotterdam:

Marathon top 1000 times vs. those achieved in Rotterdam.

Marathon top 1000 times vs. those achieved in Rotterdam.

With those top 1,000 times, I then went back to compare the head to head of Rotterdam vs. Berlin, this time not only comparing winners times as above (Limo and Makau) but all those runners who run consecutively Rotterdam and Berlin, and checked in which race did they achieve the fastest of the 2 (or 3) times. See the results:

Runners among top 1,000 marathon times having run consecutively in Rotterdam and Berlin.

Runners among top 1,000 marathon times having run consecutively in Rotterdam and Berlin.

Of the top 1,000 marathon times, 16 runners achieved some of then running consecutively in Rotterdam and Berlin (or viceversa) (3). I made this comparison assuming that they must have been in a similar fitness (though not necessary). Of the 16, 9 of them achieved the better time in Rotterdam, 7 in Berlin. Among those times, the best 4 were achieved in Rotterdam (James Kipsang Kwambai, Patrick Makau, Geoffrey Mutai, Abel Kirui).

Then, having seen all these times, tables and graphics:

  • In the last 16 years the marathon WR has been beaten once every second year (8 times).
  • Rotterdam is arguably between the 2nd and the 4th fastest marathon.
  • However, the best time in Rotterdam (2h4’27”, Duncan Kipkemboi in 2009) is only the 14th best time overall.
  • Kipchoge PB is among the top 7 times after only his 2nd attempt at the distance.
  • Kipchoge ran in Berlin in September 2013 (2h4’5″), chances are that he beats that time running consecutively in Rotterdam in 2014.

Given the size of the feat I would not bet much on it, but I would not discard it either. Either way, I will only discover what happened about 2 hours after the race, at the front, has finished.

In case you feel like cheering me up and feel sorry for being thousands of kilometers away, don’t worry: click on this link and you will arrive at a website provided by the organization in which you can leave either one or two support messages that will be shown to me when I run by the kilometer 37 or I am just 500m from the finish line (my bib number for this race will be 1599).

Finally, find a classic picture from my brother (and marathon pal) Jaime symbolizing this marathon:

—

(1) Excluding times from Boston and other races not qualifying for IAAF world records.

(2) A year later, in 2011, Patrick Makau set a new WR in Berlin, 2h3’38”.

(3) Felix Limo, Geoffrey Kipsang and Jackson Koech run 3 consecutive races in a row each.
