Wesley Korir has set a course record in capturing the Los Angeles Marathon, the 11th straight year a Kenyan man has won.
Russia's Tatiana Petrova won the women's race Monday.
Korir covered the 26.2 miles in a personal best of 2 hours, 8 minutes, 24 seconds.
Ethiopia's Tariku Jafar was second in 2:09:32 and Kenya's Laban Kipkemboi was third in 2:10:29. Korir broke the course record set by Kenya's Benson Cherono.
In the women's division, Petrova broke away from the pack after 19 miles.
She surged past Ethiopia's Amane Gobena to finish in 2:25:59. Another Russian, Silvia Skvortsova, was third in 2:28:35.
Petrova competed in the 3,000-meter steeplechase at the Beijing Olympics.
An estimated 15,000 people participated in the marathon, which was greeted by cool and cloudy conditions in downtown L.A.
It's the first time the 26.2-mile race is being run on Memorial Day. It had been held in March.
