Kenya's Joyciline Jepkosgei broke four world records as she stormed to victory at the Prague Half Marathon. The 23-year-old completed what was just her fifth half marathon in one hour, four minutes and 52 seconds — 14 seconds quicker than the record set by Peres Jepchirchir earlier this year.
And she also clocked splits of 30:05, 45:37 and 1:01:25 to break the 10km, 15km and 20km world records on the way. "I only wanted to improve my time. This is a surprise for me," Jepkosgei said.
