Brigid Kosgei breaks world record at Chicago Marathon

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. She won in Chicago last year in 2:18:35. 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. Ababel Yeshaneh and Gelete Burka, both of Ethiopia, finished second and third on Sunday. Yeshaneh's time was 2:20:51 and Burka's was 2:20:55.
