Karsten Warholm

Warholm became the first European to win the event since Volker Beck in 1980.

Warholm's time, the first sub-46 s time for the 400 m hurdles, was faster than 18 runners in the men's 400 m without hurdles.

The silver medalist in the final, Rai Benjamin, also beat the old record, with a time of 46.17 s; the bronze medalist, Alison dos Santos, was 0.02 seconds short of the old world record with a time of 46.72 s, but joined the other two in bettering the old Olympic record of 46.78 s. Warholm broke the old record without using the new "super spikes" worn by many of his competitors; he has criticized those spikes as "bullshit".

Warholm was born in the town of Ulsteinvik on Norway's western coast.

He is in a relationship with Oda Djupvik.

He enjoys fishing, cars, and building Lego.

At the Weltklasse Zürich in August, Warholm set a new European record in the event, with a time of 46.92 s, making him the third person to run under 47 seconds for the distance.
