The 37-year-old Lagat has won a record eight titles in the meet’s signature event, the Wanamaker Mile. This time, he raced the 5,000 to try to break the mark Galen Rupp set last year.
Lagat did so convincingly, winning in 13 minutes, 7.15 seconds to lower the standard by more than 4 seconds.
“We came here with one aim: to break the American record,” he said. “I felt really strong coming in.”
In second place, his training partner, Arizona’s Lawi Lalang, shattered the college record, also held by Rupp.
Sanya Richards-Ross, a five-time world outdoor gold medalist, capped a wild week by winning the 400 in 50.89. She was in Indianapolis last Sunday to cheer on her husband, New York Giants cornerback Aaron Ross. He had hoped to root for her at Millrose but was attending his grandfather’s funeral in Texas on Saturday.
World champion Jenny Simpson held off Shannon Rowbury in the Wanamaker Women’s Metric Mile in a show of strength for American middle distance running. Simpson won in 4:07.27 to beat Rowbury, the 2009 world bronze medalist, by 0.39 seconds.
Millrose moved uptown to the Armory this year after nearly a century at Madison Square Garden.
