CHICAGO (AP) — Brigid Kosgei of Kenya won the Chicago Marathon on Sunday in 2 hours, 14 minutes, 4 seconds to break the world record in the event.

The 25-year-old Kosgei bested the previous mark of 2:15:25 set by Paula Radcliffe in London 16 years ago. Kosgei won in Chicago last year in 2:18:35.

“I’m feeling good and I am happy because I was not expected to run like this,” Kosgei said.

Kosgei’s run came little more than 24 hours after fellow Kenyan Eliud Kipchoge became the first man to run 26.2 miles in less than two hours, clocking 1:59:41 in Vienna. Unlike Kipchoge’s performance, however, Kosgei’s mark was set in an official race on a record-eligible course.

Radcliffe first set a world record at Chicago in 2002 before besting her own mark a year later in London.

Lawrence Cherono sprinted across the finish in the men’s race to beat Dejene Debela by one second, finishing in 2:05:45.
