2026 London Marathon

The women's race was originally announced to include Olympic champion Sifan Hassan and world marathon champion Peres Jepchirchir, but both runners withdrew due to injury, leaving Tigst Assefa, Joyceline Jepkosgei, and Hellen Obiri as the headliners. Tigst said in the pre-race press conference that she was fitter than she was last year, when she won the race and set a 2:15:50 women's-only world record. In the men's race, the debut of Yomif Kejelcha was highly anticipated as the Ethiopian was coming off both a successful track career and several fast half marathon performances. Sabastian Sawe, the defending champion, was viewed as trustworthy given that he had voluntarily subjected himself to increased drug testing paid for by his sponsor Adidas in the lead-up to the race. However, he revealed during the pre-race press conference that he had been dealing with a back injury before the race. 5,000 m and 10,000 m world record holder Joshua Cheptegei was also entered in the race, but he had struggled in his three career marathons before London. ==Race==

Men By five kilometres into the men's race, a group of six runners had separated from the rest of the pack. Sawe, the defending champion, was joined by Paris Olympic champion Tamirat Tola, world cross country champion Jacob Kiplimo, marathon debutant Yomif Kejelcha, Deresa Geleta, and Amos Kipruto. They were led by a group of pacers through the half marathon in one hour and 29 seconds, aligned with the 60:30 target pace. The pacers were able to block the wind until after , at which point Sawe sped up (contrary to expectations that runners would run faster when behind a pacesetter). into the race, only Sawe and Kejelcha remained in the lead with Kiplimo trailing. At , the pair was still only at a projected 2:01 finish, but Sawe split a 13:54 5K run from 30 to 35K to bring the pace down to 2:00:29. Sawe's 24th mile time of 4:12 was the fastest individual mile split recorded in any marathon, but Kejelcha remained in contact with the lead. Kejelcha was finally dropped after the 25th mile, leaving Sawe by himself as he ran the stretch from 40 km to 42.195 km in 5 minutes and 51 seconds. Both Sawe and Kejelcha broke the two-hour marathon barrier, while Kiplimo broke the previous world record time of 2:00:35 in 3rd place. All of the top five runners ran a personal record time over the marathon distance. By , only Tigst, Obiri, and Jepkosgei remained. They ran the half marathon in 1:06:12, half a minute faster than Tigst's split the previous year and only two minutes slower than the 1:04:16 split run during Ruth Chepngetich's 2:09:56 mixed-gender world record run. The trio slowed in the following miles, running every 5 km split after 20 km in over 16 minutes. Nonetheless, Tigst maintained the pace enough to break her own women's-only world record by nine seconds, finishing in 2:15:41. Obiri and Jepkosgei also ran under 2 hours and 16 minutes, marking the first time that three women had broken the 2:16 barrier in the same race. ==Reception==
