Kenya's Kipyegon, Chebet break world records in Eugene

Kenya's Beatrice Chebet smashed the women's 5,000 metres world record and compatriot Faith Kipyegon broke her own 1,500m record again as the Eugene Diamond League meet lived up to its billing on Saturday.

Tsegay, along with Kenyan Agnes Jebet Ngetich, kept pace with Chebet for almost the entire race, but had no answer when Chebet kicked for home, and Jebet Ngetich finished second in 14:01.29, the third fastest time ever.

The 50th Prefontaine Classic promised fireworks, and in the final race of the evening Kipyegon ran a time of three minutes 48.68 seconds, improving her previous world mark of 3:49.04 set in Paris last July.

Kipyegon, triple Olympic champion over the distance, recently fell short in her attempt to become the first woman to run a mile in under four minutes, but the 31-year-old shook that disappointment off in style.

The Kenyan upped the pace down the back straight, powering around the final bend and pushed for the line, her
