Geoffrey Kipsang Kamworor retained his title as Peris Chepchirchir stunned a classy line up to win the IAAF World Half Marathon Championships titles in Cardiff, Wales yesterday.

Kamworor, who works for National Police Service, dictated the men’s high pace and had sweet revenge over four-time world champion Mo Farah, who beat him in the 10,000m final in Beijing last year.
