Rupp, who is a former track star and three-time Olympian, finished the Boston Marathon in second place a year ago and became the first American since 1964 to win a medal in the 10,000 meters at the 2012 London Olympics.
Three-time Olympian Galen Rupp was the victor, in 2:09:20. The two-time Olympic medalist (silver in the 10,000-meter in 2012, bronze in the marathon in 2016) is the first American to win the Chicago Marathon since Khalid Khannouchi in 2002.
Last year's champion Abel Kirui of Kenya finished second.
"This is my third marathon and I'm very happy to have won here", Dibaba said after her win. I made the mistake in the past of going out a little too hard too soon and you still have a long ways to go for several miles. Dibaba was out in front on her own, having gapped Kosgei, while Kirui, Rupp and Ethiopian Sisay Lemma were in contention duking out who would finish where on the men's podium.
"I just tried to relax and when I make the move be decisive".

Ethiopian Tirunesh Dibaba pushed toward a course-record pace nearly from the start to win the women's side of the Marathon in 2:18:31. She went out with an aggressive pace and was all alone by the 30-kilometer mark. Her sub-2:21 clocking is a course record for Americans.
Florence Kiplagat's 10km time of 32:28 was also 19 seconds faster than Radcliffe's record split but by 15km it was Hasay, third this year in Boston, leading in 49:02, three seconds under record pace. The Kenyan fell back with 10km remaining, leaving Dibaba alone to the end. Amongst her successes are: three Olympic gold medals, she is nine-time world champion and world record holder over 5,000m.
She has won several laurels for the East African country at the Olympics and in other worldwide competitions.
Rupp was second at the Boston Marathon.
