The 24-year-old, who finished fourth in the Beijing Olympics, achieved the result in her second attempt, improving on the previous world mark of 77.80 meters set by Russia's Tatyana Lysenko on Aug. 15, 2006.

Defending champion Betty Heidler of Germany took the silver with 77.12 meters and Slovakia's Martina Hrasnova was third with 74.79.

Kenya collected two gold medals and two silvers on the day as they took 1-2 in the men's marathon and women's 5,000m. Ethiopians finished third in both events.

Abel Kirui clocked a championship record of two hours six minutes and 54 seconds around the course in central Berlin, ahead of compatriot Emmanuel Mutai in 2.07:48. Ethiopia's Olympic bronze medallist Tsegay Kebede finished third in 2.08:35.

It was only the second marathon victory after Vienna last year for the 27-year-old Kirui who finished second behind Haile Gebrselassie during the Ethiopian's then-world record run in the 2007 Berlin Marathon.

"Berlin is my city. I love Berlin and enjoyed running here. When I came to Berlin I felt so confident," Cheruiyot said.

Vivian Cheruiyot and Sylvia Jebiwott Kibet finished 1-2 in the women's 5,000 meters, outsprinting defending champion Meseret Defar of Ethiopia at the line.

Cheruiyot, silver medalist two years ago in Osaka, clocked 14 minutes 57.97 seconds. Kibet, who finished fourth in Beijing Olympics, took silver in 14:58.33 and Defar settled for bronze in 14:58.41.
