Dennis Kimetto set a world best in the 25 kilometers Sunday, leading a 1-2-3 Kenyan finish in only his third race outside his home country.
Kimetto crossed the line in Germany's oldest city road race at historic Olympic Stadium in 1 hour, 11 minutes, 18 seconds. He beat the mark set by compatriot Sammy Kosgei at the same event two years ago by 32 seconds.
Wilfred Kigen was second in 1:11:29, followed by Jacob Kendagor. Kimetto's time for the nearly 16 miles was the seventh world-best mark set at the race since it began in 1981.
Kimetto this season has won half-marathons in United Arab Emirates and Berlin.
