John Korir wins the Boston Marathon/HANDOUT
Despite storming to the fifth-fastest marathon time in history, John Korir has made it clear that the late Kelvin Kiptum’s world record is, for now, far from his thoughts.
‎The men’s 42km benchmark stands at 2:00:35, a historic mark Kiptum etched into the record books at the Chicago Marathon in 2023, becoming the first man to shatter the 2:01 barrier.
‎On Monday, Korir delivered a ruthless, front-foot performance on the streets of Boston, powering to victory at the Boston Marathon in a course record time of 2:01:52, catapulting himself to fifth on the all-time list.

‎In doing so, he obliterated the 15-year-old course record of 2:03:02 set by fellow Kenyan Geoffrey Mutai back in 2011.  ‎Korir’s electric run also saw him slice through his previous personal best of 2:02:24, set during his emphatic victory in Valencia last December.
‎Only an elite quartet; Kiptum (2:00:35), Eliud Kipchoge (2:01:09), Kenenisa Bekele (2:01:41) and Sisay Lemma (2:01:48), have clocked faster times.
‎Even with such a seismic performance, Korir remains grounded, insisting his focus is firmly fixed on winning rather than chasing the clock. ‎“I am not worried about the world record at the moment. I just want to run and win, but if the world record comes, it will be good,” Korir said. ‎“Right now, the world record is not in my mind.”
‎In Boston, Korir held off Tanzania’s world marathon champion Alphonce Simbu, who clocked 2:02:47, and former Boston champion Benson Kipruto, who followed closely in 2:02:50. 
‎Interestingly, the Kenyan ace revealed he was unaware of his record-breaking feat even after crossing the line.
‎“When I crossed the finish line, I did not know that I had broken the course record; I was only told after,” he admitted. ‎However, Korir knew from deep within the race that he was locked into a punishing, record-threatening rhythm. ‎“Last year, during my win, I fell at the start and wasn’t sure I would run fast. This year, I was in good shape and knew I would run fast.”
‎“When I crossed the 40km mark, I saw I was at 1:55, so I knew I was well under 2:02 pace and pushed to maintain it all the way to the finish,” he explained. ‎“It feels good to have run such a fast time.”
‎The 29-year-old had previously triumphed in the 2025 edition, clocking 2:04:45, with Simbu again finishing runner-up in 2:05:04, while compatriot Cybrian Kotut sealed third in the same time.  ‎For his latest masterclass, Korir walked away with $150,000 (Sh19.4 million), plus a handsome $50,000 (Sh6.5 million) bonus for rewriting the course record.
‎His Boston dominance had been foreshadowed earlier in the season when he opened his campaign in commanding fashion at the Sirikwa Classic Cross Country Tour on February 14. ‎There, he surged to victory in the senior men’s 10km, clocking 29:44 to see off Amos Kiprotich and Silas Senchura, both of whom timed 29:46.
