Ever wonder what it takes to run 26.2 miles faster than most of us can drive through city traffic? Meet John Korir, the Kenyan marathoner who’s rewriting the record books and inspiring fans around the world. From Chicago to Boston, his name has become synonymous with speed, grit, and the pursuit of greatness.
Who Is John Korir?
John Korir was born in 1996 in Kitale, Kenya, a region famous for producing some of the world’s best distance runners. By his late 20s, he had already carved out a place among the sport’s elite.
He won the 2024 Chicago Marathon in 2:02:44 — the second-fastest time in the race’s history.
In 2025, he claimed victory at the Boston Marathon, joining his brother Wesley Korir, who won the same race in 2012. Together, they became the first brothers to win Boston.
His half marathon personal best is an astonishing 58:50, set in Ras Al Khaimah in 2024.
That combination of speed and consistency has made him one of the most exciting athletes to watch today.

Like many Kenyan runners, Korir grew up running to school and through the hilly terrain of the Rift Valley. But his career really took off when he began competing internationally.
