John Korir Wins 2025 Boston Marathon, Sets New Record

John Korir of Kenya won the 2025 Boston Marathon with a time of 2:04:45, overcoming an early fall to surge ahead in the final miles and secure victory. His win is particularly notable as he joins his brother Wesley Korir, the 2012 Boston champion, making them the first set of brothers to have both won the historic race. John, who also won the 2024 Chicago Marathon, credited advice from Wesley for helping him strategize on Boston’s challenging course, especially during the decisive stretch at Heartbreak Hill. Korir’s strong finish separated him from a competitive field that included past champions, with Americans also showing strong performances. With his Boston win, John pledged his earnings to support a middle school in Kenya. This victory cements the Korir brothers’ place in marathon history, highlighting both family legacy and individual achievement.
