The Two-Hour Marathon Barrier Is Broken: Sawe's 1:59:30, Explained

Sabastian Sawe ran 1:59:30 in London, the first sub-two-hour marathon in a record-eligible race. Here's what happened and why it counts.

By Written Facts Staff6 min read

If you've ever watched a finish clock at a fall road race, you know the moment when it rolls past a round number and the runners just behind it groan. For decades, 2:00:00 was that number for the marathon, and in a legal race nobody got in ahead of it. That ended on April 26, 2026. Sabastian Sawe of Kenya won the London Marathon in 1:59:30. It was the first marathon under two hours in a race that counts for records, and World Athletics has since ratified it as the world record.

What happened in London

The race didn't start with a reckless sprint. The lead pack went through 5K in 14:14 and 10K in 28:35, which was right on the pace of the old world record. Six men reached halfway together in 1:00:29.

At that point the group was on course for roughly a two-hour finish, not clearly under it. The record came from the second half. Subtracting the halfway split from the finish time gives Sawe a second half of about 59:01, roughly 88 seconds faster than his first. Running the back half faster than the front is called a negative split. Doing it by that much at world-record pace is what turned a fast race into a historic one.

Sawe also had company. Yomif Kejelcha of Ethiopia, running his first marathon, finished second in 1:59:41, also under two hours and only 11 seconds back. Jacob Kiplimo of Uganda was third in 2:00:28, 58 seconds behind the winner. Conditions were reported as ideal.

The women's race was historic too. Tigst Assefa ran 2:15:41, a world record for a women-only race, and it has also been ratified.

What 1:59:30 means in numbers

A marathon is 42.195 km (26.2 miles). Holding 1:59:30 for the whole distance works out to these averages, calculated from the finish time:

  • About 2:50 per kilometer
  • About 4:33 per mile
  • About 14:10 for every 5K, run more than eight times in a row
  • About 21.2 km/h (13.2 mph)

For comparison, many fit recreational runners would be pleased to hold that per-mile pace for a single mile.

Wait, didn't Kipchoge already do this?

He did, but not in a race. On October 12, 2019, Eliud Kipchoge ran 1:59:40.2 in Vienna in the INEOS 1:59 Challenge. It was a remarkable run, but it was never eligible as a record, for several reasons:

  • It wasn't an open competition. The event was built around one athlete.
  • Pacemakers rotated in and out in fresh groups, which isn't allowed under record rules.
  • Drinks were handed to him from a bicycle instead of collected at fixed stations.
  • A pace car projected a laser line on the road to show the pacers where to run.

Vienna was itself a second try. Kipchoge's 2017 Nike Breaking2 attempt in Italy, run under similar controlled conditions, missed two hours by about 25 seconds.

So Vienna showed that a human body could run a marathon in under two hours. London showed it could happen in a real race, with real rivals, under the normal rules. Sawe's time is also about 10 seconds faster than Kipchoge's Vienna run, though the two efforts were run under such different conditions that the comparison is only rough.

How fast the record fell

The official men's record has dropped quickly over the past eight years:

  • 2:01:39: Eliud Kipchoge, Berlin, September 16, 2018
  • 2:01:09: Eliud Kipchoge, Berlin, September 25, 2022
  • 2:00:35: Kelvin Kiptum, Chicago, October 8, 2023 (ratified February 6, 2024)
  • 1:59:30: Sabastian Sawe, London, April 26, 2026

That is 2 minutes 9 seconds off the record in under eight years. Sawe's jump alone was 65 seconds. For a record that usually moves by a few seconds at a time, that is a huge step.

The shoes

Equipment is part of the story, as it has been in every recent marathon record. Sawe, Kejelcha and Assefa all wore the Adidas Adizero Adios Pro Evo 3, a racing shoe that weighs about 97 grams (3.4 ounces). It came out as a limited release, with reported prices around $500.

Shoes don't run the race. Training, pacing, competition and good weather all matter. But the fact that both men who broke two hours wore the same model is likely to keep the debate over shoe technology going.

Making it official

A fast time doesn't become a world record when the runner crosses the line. World Athletics has to review it first, including the course measurement, the timing and the doping controls. Sawe's 1:59:30 was ratified as part of a batch of seven senior records and one U20 record set in the first five months of 2026, announced in reports dated July 23, 2026. Assefa's 2:15:41 was ratified in the same batch.

After the barrier fell

The record hasn't been threatened since. Sawe withdrew from the Berlin Marathon in August with a stress fracture. That fall classic, run on September 27, went to Guye Adola of Ethiopia in 2:02:50. Berlin's course record is still Kipchoge's 2:01:09 from 2022.

That leaves 1:59:30 as the mark to beat this fall marathon season. How much lower it can go is anyone's guess. It's worth noting, though, that the first sub-two-hour race produced two of them, and that the winner ran his second half in about 59 minutes. Until recently, two hours looked like a hard limit for the marathon. Now it's simply a fast time.
