Kenya's Brigid Kosgei ran the fastest half-marathon ever by a woman on Sunday, winning the Great North Run in Newcastle, UK in a time of 1:04:28.

Her time was 23 seconds quicker than the world record set in 2017 by fellow Kenyan Joyciline Jepkosgei but the course in the northeast of England is not eligible for records.

Kosgei, who won this year's London Marathon, led a Kenyan sweep of the top four places, with Magdalyne Masai second (1:07.36) and Linet Masai third (1:07:44).

British distance runner Mo Farah won the men's elite race for a record sixth successive year as he warms up to defend his Chicago Marathon title next month.

Four-time Olympic champion Farah, 36, was pushed hard by Tamirat Tola, but proved too strong in the final mile for the Ethiopian, finishing the 21.8-kilometre course in 59 minutes and seven seconds, winning by six seconds.

Abdi Nageeye of the Netherlands was third in 59:55.
