Kipchoge pulled away over the last two miles for his first major marathon victory, finishing in 2 hours, 4 minutes, 11 seconds. He was followed by Sammy Kitwara in 2:04:28 and Dickson Chumba in 2:04:32.
Jeptoo was timed in 2:24:35 in winning her fourth straight major marathon. She also captured the 2013-14 World Marathon Majors points championship and took the Boston Marathon in April.
Mare Dibaba of Ethiopia (2:25:37) was second and Florence Kiplagat of Kenya (2:25:57) was third.
The winners earned $100,000. Jeptoo receives an extra $500,000 for winning the series championship.
Ideal conditions — sunny skies and 46-degree temperatures — greeted runners at the start. The men’s pack stayed together for about 20 miles before Kipchoge, Kitwara and Chumba drew away.
Kipchoge and Kitwara were side by side with Chumba right behind after 24 miles. But Kipchoge made it look easy down the stretch. He made a quick burst and was in command as he headed toward the finish at Grant Park.
Jeptoo hasn’t lost a major marathon since she finished second in a sprint to Ethiopia’s Atsede Baysa in the 2012 Chicago Marathon. She smashed the course record to repeat as Boston Marathon champion in the spring and came away with an easy victory in Chicago for the second straight year.
She pulled away after 23 miles, with no one near her at the end. Jeptoo raised her arms as she crossed the line and sank to her knees.
