Wilson Kipsang of Kenya set a world record in winning the 40th Berlin Marathon in 2 hours, 3 minutes, 23 seconds on Sunday.
The 31-year-old Kipsang knocked 15 seconds off compatriot Patrick Makau's previous mark of 2:03:38 set in Berlin in 2011. Kipsang was just four seconds short of the record when winning in Frankfurt the same year.
It was the eighth world record in Berlin in 15 years, strengthening its reputation as the world's fastest course.
"I think I can run even faster," said Kipsang, who earned 40,000 euros ($US54,000) in prize money plus another 50,000 ($68,000) for breaking the record.
Eliud Kipchoge of Kenya was second in 2:04:05, improving his personal best by a minute and a half in his second marathon, while Kenya's Geoffrey Kipsang no relation to Wilson was third in 2:06.26.
