Two-time world champion Abel Kirui denied Dickson Chumba a second straight Chicago Marathon title, seizing a narrow lead in the closing kilometers and holding on for the win in the Windy City on Sunday.
Kirui, the 2012 Olympic silver medallist, won in 2hrs 11min 23sec with Chumba second in 2:11:26 and Gideon Kipketer third in 2:12:20.
While Chumba was unable to repeat his 2015 triumph, Kenya's Florence Kiplagat won her second straight Chicago crown, powering to a dominant victory in 2:21:32, almost two seconds ahead of runner-up Edna Kiplagat's 2:23:28.
Valentine Kipketer completed the Kenyan women's sweep, finishing third in 2:23:41.
