The current High School 800m Record holder and World Indoor 800m Champion Cooper Lutkenhaus announced he will make his Diamond League debut in his first outdoor season as a professional. He is scheduled to compete in Stockholm on June 7th and Eugene on July 4th.
Lutkenhaus is still 17 years old, turning 18 on December 19, 2026, and after running 1:42.27 at Hayward Field to place 2nd at the USATF 800m Championship he's to no ones surprise having success on the professional circuit. As a high school sophomore he broke the High School National Record 4 times that previously held by Michael Granville (Bell Gardens, CA), who ran 1:46.45 in 1996, for 29 years.
During the indoor season Lutkenhaus ran 1:44.03, won the USATF Indoor 800m Championship, then the World Athletics Indoor 800m Championship. In his second World Championship appearance he ran three rounds of 800m races over three days running 1:46.24 in the prelims, 1:44.29 in the semi-finals and 1:44.24 to win the finals against a world class field.
Lutkenhaus, now a professional athlete, is no longer eligible to better high his school National Record, but his 1:42.27 is already a U18 World Record and he'll contest Nijel Amos (Botswana) U20 World Record of 1:41.73 this season at just 17 years of age.
Every time Lutkenhaus touches the track it is must see TV as the ceiling on what a young phenom can do was blown away last year.
In Stockholm, he'll be tested facing off against Emmanuel Wanyonyi, who is the reigning Olympic and World Champion over 800m. Wanyonyi is only 21 years old, and while four years older than Lutkenhaus is an expected rivalry that will play out over the twos track careers in the Diamond League and World stage and the first of many battles will take place live on FloTrack for the US audience!
While Lutkenhaus' 1:42.27 is hard to look past, he was a star going back to his Pike MS days still holding the Brooks PR Junior 800m record at 1:54.20 and ran 48.70 and 1:53.59 over 400m and 800m winning both at Nike Indoor Nationals in 2023. He also ran 4:45 as an 8th grader for 1600m.
