It was also a win for middle- and long-distance runner Faith Kipyegon.
The double Olympic champion said she is looking forward to a good summer in Paris where she will chase two medals, after winning both the 1500m and 5,000 metre races at the trials.
Kipyegon won the 1,500 metre with a time of 3.53.99, short of her world record time of 3:49.11.
“I wanted to execute as fast as possible and see what was possible at the finish line. Because people think that you can’t run fast at high altitudes, but I wanted to see if I can run fast or if the weather is going to affect me in any way,” she said after the race.
Kipyegon said she hopes she can maintain her current form heading to the Olympics.
Women’s 800m world champion Mary Moraa qualified for Paris in second place, with her sister Sarah Moraa in third.
The athletics competition at the Olympics taking place at the Stade de France in Paris from 1-11 August.
