“I came into the race wanting to put myself in the best position I could to win,” Mackey said after the race. “But when I crossed the line, it was almost like I couldn’t quite believe that it happened.”
Mackey, of Seattle’s Brooks Beasts Track Club, closed her final lap in just over 62 seconds, according to LetsRun. Her time of 8:52.99, over Renata Plis of Poland, was a personal best by almost seven seconds.
The Diamond League is a worldwide series of outdoor track meets. Competitors earn points dictated by place in designated events, which are tallied for an end-of-the-year overall champion. Only four Americans have ever won Diamond Race distance events, which include the 5,000 meters and 3,000 meters: Lauren Fleshman in 2011, Shannon Rowbury in 2013, and Ben True in 2015.
