Dennis Kimetto is officially on fire in 2013.
The 29-year-old Kenyan won the 2013 Chicago Marathon in impressive fashion on Sunday, adding yet another course record to his resume this year.
In fact, second-place finisher Emmanuel Mutai was happy with his time, despite the loss.
On the women's side, Rita Jeptoo of Kenya (who else?) won her fifth career marathon and second marathon of 2013. Jemima Jelagat Sumgong came in second.
Here's a look at the top finishers of the 2013 Chicago Marathon on Sunday.
Dennis Kimetto, Kenya
Dennis Kimetto not only won the 2013 Chicago Marathon on Sunday, he also set the course record with an unofficial time of 2:03:45, eclipsing last year's mark by almost a whole minute, per the Chicago Tribune.
After getting edged by Geoffrey Mutai in the blistering 2012 Berlin Marathon, he has been red-hot in 2013, capturing course records at both the Chicago Marathon and the Tokyo Marathon.
Emmanuel Mutai, Kenya
Emmanuel Mutai finished seven seconds behind Kimetto on Sunday, posting a time of 2:03:52.
Dating back to 2007, Mutai has won two marathons (Amsterdam, London). The London Marathon marked a breakthrough for the 29-year-old, as he posted a course record of 2:04:40.
The Kenyan also had a strong showing in the 2011 New York City Marathon, only to be bested by the impressive Geoffrey Mutai.
Emmanuel now has four career second-place finishes in marathons.
Sports agent Michel Boeting quoted Mutai after the race:
Rita Jeptoo, Kenya
This is Rita Jeptoo's fifth marathon win of her career. Her seventh-place finish at the World Championships in Helsinki was the only "blemish" to her outstanding resume.
The 32-year-old Kenyan continues to be a formidable opponent for the women's field, posting an unofficial time of 2:19:57 on Sunday and winning by 51 seconds. Beyond the Chicago Marathon, she has also won the Boston Marathon twice (2006, 2013), and the Stockholm and Milan Marathons in 2004.
Jemima Jelagat Sumgong, Kenya
Jemima Sumgong ran well on Sunday, but the 28-year-old from Kenya ultimately wasn't able to get the best of Rita Jeptoo.
Sumgong won the Las Vegas (2006), Castellon (2011) and Rotterdam Marathons (2013). She also placed second in a thriller against Sharon Cherop in the 2012 Boston Marathon. She continues to be a worthy challenger to some of the top marathon runners in the world.
Sumgong set a personal record on Sunday, sweeping across the finish line in 2:20:48.
