Emmanuel Mutai shattered the course record at the London Marathon on Sunday, the Kenyan winning the men's race in 2 hours 4 minutes and 40 seconds.
Mutai finished second last year and he went one better this time thanks to a spectacular run that beat the previous best time of 2:05.10 set by Samuel Wanjiru in 2009.
The 26-year-old's time was also the fifth-fastest ever in a marathon.
Kenya's Mary Keitany won the women's race in 2:19.18 relegating the defending champion Liliya Shobukhova of Russia into second, with Kenya's Edna Kiplagat in third on her London Marathon debut.
