Sabastian Sawe runs first ratified sub-two-hour marathon in London

Sabastian Sawe runs first ratified sub-two-hour marathon in London

New Capabilities
By Newzino Staff |

Two men finished a competitive marathon under two hours on the same day, ending a barrier that stood since the modern marathon was timed

Today: Sawe runs 1:59:30; Kejelcha 1:59:41 on debut

Overview

For 117 years, no person had run a marathon in under two hours under standard race conditions. On Sunday morning in London, two did. Kenya's Sabastian Sawe crossed the finish line on The Mall in 1 hour, 59 minutes, 30 seconds, lopping 65 seconds off the previous world record. Ethiopia's Yomif Kejelcha, running his first marathon ever, finished 11 seconds behind him in 1:59:41.

Why it matters

A physiological ceiling once treated as the limit of human endurance has been crossed in open competition — and three runners cleared it or came within a minute on the same day.

Timeline

  1. Sawe runs 1:59:30; Kejelcha 1:59:41 on debut

    Record

    Two runners finish a competitive marathon under two hours on the same day. Kiplimo, third, runs 2:00:28 — also under the previous world record. Tigst Assefa lowers the women-only world record to 2:15:41 in the same race.

  2. Sawe runs 2:02:16 in Berlin to lead the world

    Performance

    Sawe wins his third marathon in three starts, signalling he is the heir apparent to Kiptum's pursuit of the barrier.

  3. Kiptum dies in car accident at age 24

    Death

    Kiptum and his coach are killed when their vehicle leaves a road near Kaptagat, Kenya, days before he was to begin a Rotterdam build-up aimed at sub-two.

  4. World Athletics ratifies Kiptum's record

    Ratification

    Kiptum's 2:00:35 becomes the official men's world record after standard review.

  5. Kelvin Kiptum runs 2:00:35 in Chicago

    Record

    The 23-year-old Kenyan takes 34 seconds off Kipchoge's record, finishing his second 13.1 miles in 59:47 and bringing the sub-two barrier into striking distance.

  6. Kipchoge sets official world record in Berlin

    Record

    Kipchoge runs 2:01:09 in open competition, lowering his own ratified world record by 30 seconds.

  7. Kipchoge breaks two hours in Vienna — but not for the record book

    Attempt

    At the INEOS 1:59 Challenge in Vienna, Kipchoge runs 1:59:40 with rotating pacers and a pace car. World Athletics declines to consider it for ratification because of the assistance.

  8. Nike's Breaking2 falls short by 25 seconds

    Attempt

    Kipchoge runs 2:00:25 at Italy's Monza racetrack in Nike's first engineered sub-two attempt. The effort introduces the carbon-plated Vaporfly prototype that would reshape distance running.

Scenarios

1

World Athletics ratifies 1:59:30 as the new world record

Discussed by: Race director Hugh Brasher; coverage in Reuters, World Athletics, BBC

The standard ratification process — drug testing, course measurement verification, pacemaker compliance — proceeds without complication. Within roughly two months, 1:59:30 enters the record books as the first sub-two marathon. This is the consensus expected outcome given that London is a long-established record-eligible course and there were no irregularities in the race.

2

Sub-two becomes routine at the next major marathons

Discussed by: Athletics analysts at LetsRun, Sports Illustrated, The Times

Just as sub-four-minute miles multiplied within months of Bannister's run, several runners go under two hours at Berlin in September, Chicago in October, and the next London. The fact that two men did it on the same day, with a third within a minute, suggests the barrier was psychological as much as physiological. Expect more attempts on flat, fast courses with similar pacer arrangements.

3

Doping or technology controversy clouds the result

Discussed by: Athletics Integrity Unit; investigative reporting at LetsRun and The Athletic

Sub-two times draw renewed scrutiny over carbon-plated 'super shoes' and East African doping cases. World Athletics could tighten shoe rules — current limits permit one carbon plate and 40mm of stack height — or open a probe into specific athletes. Sawe has preempted some of this by publicly requesting more frequent testing, but the broader credibility debate intensifies.

4

Tokyo or Berlin engineers a 1:58 attempt

Discussed by: Marathon historians at Outside, Runner's World

With the barrier broken, attention shifts to the next round number. A major marathon — likely Berlin or a one-off event — assembles pacemakers and conditions for a 1:58 push. Whether that requires another decade or just the next training cycle is the open question; physiologists once estimated the human limit at 1:57:58.

Historical Context

Roger Bannister breaks the four-minute mile (1954)

May 1954

What Happened

On a windy afternoon at Oxford's Iffley Road track, medical student Roger Bannister ran 3:59.4 with pacing help from Chris Brasher and Chris Chataway, becoming the first person to run a mile in under four minutes. The barrier had stood for nine years since Sweden's Gunder Hägg ran 4:01.4 in 1945, and physiologists had argued the human body could not cross it.

Outcome

Short Term

Australia's John Landy lowered the mark to 3:57.9 just 46 days later. Within three years, 16 more runners ran sub-four.

Long Term

The mile record now stands at 3:43.13, set by Hicham El Guerrouj in 1999. Sub-four miles have been run by more than 1,700 athletes.

Why It's Relevant Today

The closest analogue to Sunday's race. Both barriers were treated as biological ceilings; both fell in races with paced lead-outs; both proved psychological as much as physiological. The pattern that followed Bannister — a flood of athletes clearing the mark within years — is what many expect now.

Bob Beamon's leap at Mexico City (1968)

October 1968

What Happened

American long jumper Bob Beamon jumped 8.90 metres at the Mexico City Olympics, breaking the world record by 55 centimetres — a margin so large that the mark had been called 'unbreakable' for a generation. Officials had to summon a steel tape because the optical measuring device did not extend that far.

Outcome

Short Term

Beamon's jump won Olympic gold by 71 centimetres over the silver medalist.

Long Term

The record stood for 23 years before Mike Powell jumped 8.95 m in 1991. Beamon's mark remains the Olympic record.

Why It's Relevant Today

A reminder that some performances reset expectations of what is possible. Sawe's 65-second margin over Kiptum's record is the largest single improvement in the men's marathon mark since electronic timing began — closer to a generational leap than an incremental gain.

Nike Vaporfly arrives at the marathon (2017)

2017

What Happened

Nike unveiled the Vaporfly 4%, the first commercially available marathon shoe with a full-length carbon fibre plate sandwiched in a thick, springy foam midsole. Independent studies measured a 4% improvement in running economy compared with previous racing flats. Within months, every men's and women's marathon major had been won in the new shoes.

Outcome

Short Term

World records and major marathon wins shifted to the new shoe technology, with rivals scrambling to catch up.

Long Term

World Athletics introduced rules in 2020 capping stack height at 40 mm and limiting plates. Carbon-plated 'super shoes' from Adidas, ASICS, and others now dominate elite racing.

Why It's Relevant Today

Sub-two would not have happened in 2026 without the shoe revolution that started in 2017. Sawe and Kejelcha both wore Adidas Adios Pro Evo prototypes; understanding the result requires understanding that technology is part of why the barrier fell now rather than later.
