In one of the most significant moments in athletics history, Kenya's Sabastian Sawe became the first person to break the two-hour mark in an officially sanctioned marathon on Sunday, crossing the finish line at the London Marathon in 1 hour, 59 minutes and 30 seconds. The 29-year-old defending champion, running along the iconic final straight on The Mall, surged clear of his rivals in the closing kilometres to shatter the previous men's world record — set by fellow Kenyan Kelvin Kiptum in Chicago in 2023 — by a remarkable 65 seconds. "What comes today is not for me alone," Sawe said after the race, "but for all of us today in London."

The achievement was made all the more extraordinary by the performances behind him. Ethiopia's Yomif Kejelcha, competing in his very first marathon, also finished under two hours with a time of 1:59:41, while Uganda's Jacob Kiplimo crossed in 2:00:28 — itself seven seconds faster than Kiptum's former world record. All three men on the podium finished beneath what had until Sunday been the sport's ultimate barrier. Sawe, who wore Adidas's new Pro Evo 3 shoe — weighing less than 100 grams — ran the first half in 1:00:29 before accelerating, covering the second half in just 59 minutes and one second.

The sub-two-hour milestone had famously been achieved once before, but not under official conditions. Kenyan long-distance legend Eliud Kipchoge ran 1:59:40 in Vienna in October 2019, in a specially arranged event that used rotating pacemakers and did not conform to standard competition rules. That effort, while celebrated as a proof of concept, was never ratified as a world record. Sawe's time on Sunday not only matches official record criteria but also beats Kipchoge's Vienna mark by ten seconds. Experts attribute the latest leap in performance to advances in footwear technology — modern carbon-plate "supershoes" are estimated to save runners around a minute and a half over the full 42.195-kilometre distance — as well as improved nutritional strategies, with elite athletes now consuming over 100 grams of carbohydrates per hour during races.

Some athletics specialists believe the record may not stand for long. London, while largely flat, is not considered the fastest marathon course in the world; circuits in Berlin and Valencia are seen as potentially quicker venues. Should the same calibre of field assemble there under ideal conditions, further improvements could follow. "The goalposts have literally just moved for marathon running," said Paula Radcliffe, herself a former London Marathon winner, during BBC commentary.

Elsewhere at Sunday's race, Ethiopia's Tigst Assefa defended her women's title in 2:15:41, the fastest time ever recorded in a women's-only marathon, though it remained 16 seconds short of the course record set by Radcliffe herself in 2003 in a mixed-gender race. In the wheelchair events, Swiss athletes Marcel Hug and Catherine Debrunner both claimed titles, with Hug securing his sixth consecutive men's victory and eighth overall.
