It’s official: Cooper Lutkenhaus is the youngest men’s Diamond League track winner in history
By LetsRun.com
American teen sensation Cooper Lutkenhaus continued his amazing rookie professional season at the Stockholm Diamond League on Sunday, where he ran 1:42.70 to defeat 2023 world champion Marco Arop of Canada and win his Diamond League 800-meter debut.
We already broke down Lutkenhaus’s amazing run as it happened on Sunday. But after a day to review the statistics, we can confirm that the 17-year-old Lutkenhaus’s win in Stockholm was indeed historic. He is the youngest man to win a running event at a Diamond League in the 17-year history of the series.

The Stockholm meet organizers have also published the estimated amount of distance each runner ran in the 800m on Sunday. They estimate that Lutkenhaus, who ran much of the race on the outside of lane 1 or inside of lane 2, ran the second-most distance of anyone in the race: 806.4 meters.
Obviously, positioning is one of the challenges of running the 800, but we thought it would be fun to calculate what everyone in the race would have run had they run the exact same pace but only run exactly 800m.
Hypothetical 800m Race Results from Stockholm
