Kenya's Dennis Kimetto has broken the marathon world record in Berlin, winning the race in a time of two hours, two minutes and 57 seconds.

The 30-year-old broke away in a seven-man group that included fellow Kenyans Emmanuel Mutai and Geoffrey Kamworor.

He shook off Mutai with just under three miles remaining to become the first man to run a marathon in less than two hours and three minutes.

It is the second year running the world record has been broken in Berlin.
