Beatrice Chepkoech broke the meeting record to win the women's 3000m steeplechase in the sixth leg of the Diamond League meeting on Friday evening in Lausanne.
Chepkoech clocked 9:05.98 in her first race in her specialist discipline since helping to pace Faith Kipyegon to her world 5000m record in Paris.
Chepkoech was joined by world U20 silver medallist Sembo Almayew, who set the world lead of 9:00.71 to win in Florence at the start of the month, but they were both happy to sit behind the pace lights indicating a world-leading tempo.
As the pair moved away from the rest of the field, Almayew was chasing Chepkoech rather than the clock and she finished second behind the world record-holder, running 9:06.82.
Uganda’s Olympic champion Peruth Chemutai was third in 9:11.91.
Elsewhere, Mary Moraa danced with delight after a decisive 800m win, the world bronze medallist kicking away from Keely Hodgkinson off the final bend and recording a season’s best of 1:57.43.
Moraa and Hodgkinson followed the pacemaker through 400m in 56.65 and were side by side as they reached the final bend, but Moraa kicked again to hold off the world and Olympic silver medallist – who ran her world-leading 1:55.77 British record in Paris earlier this month – and win by almost a second.
Hodgkinson was runner-up in 1:58.37 and Jamaica’s Natoya Goule third in 1:58.90.
