On Patriots' Day, John Korir turned a marathon into a solo procession. Defending champion John Korir shattered the Boston Marathon course record on Monday, riding a tailwind to outrun the strongest field in race history and win in 2 hours, 1 minute, 52 seconds — the fifth-fastest marathon of all time. He crossed the line on Boylston Street with his tongue out and his arms wide, a champion at play.
The Kenyan did not lead early. Korir was second at the half-way stage in 1:01:50, seven seconds behind Lemi Berhanu. The men's race had opened fast under clear skies. It was a chilly start to the 130th running of the race, with temperatures at 45F on a clear day that offered a tailwind of up to 10mph to the runners. Through the middle miles Ethiopia's Milkesa Mengesha pressed ahead, and a chase group formed behind him.
Decided on the hill
Heartbreak Hill settled it. The 29-year-old cemented himself as a Boston legend by launching an attack up Heartbreak Hill, blitzing the uphill 21st mile in 4:42 to open a 22-second gap on the field. Unlike a year before, he did not ease once he crested it. Korir pushed on the downhills through Beacon Street in Brookline, through Kenmore Square in the shadow of Fenway Park, and did not stop until breaking the tape in 2:01:52. He continued to press over the closing miles, extending his lead to 26 seconds by 35km and 43 seconds by 40km.
The chasing runners ran themselves into the record books too. Runner-up Alphonce Felix Simbu of Tanzania in 2:02:47 and third-placer Benson Kipruto of Kenya in 2:02:50 were both under the old record as well. Korir's mark erased a figure that had stood for well over a decade: a new course record of 2:01:52, the previous record of 2:03:02 having been set in 2011 by Kenya's Geoffrey Mutai.
A run of victories
This was not an isolated result but the crest of a long, unbroken run. Korir has now won the past four marathons that he has completed, having notched up victories in Chicago in 2024, Boston and Valencia in 2025 and Boston again in 2026. His return to Boston carried an added layer of family history. A year after joining his brother Wesley, the 2012 champion, as the only relatives to win the race, Korir broke away from the pack as it headed into Heartbreak Hill and opened a large lead.
He said the fast time had surprised even him. "When they told me I had run the course record, that's when I started to be happy," said the Kenyan. "I knew I would defend my title. But I didn't know I could run that fast."
Two brothers, one course, and now a record with Korir's name on it.
