Norway's Olympic and double world champion Karsten Warholm will launch his defence of the 400m hurdles Diamond Trophy at the fourth Wanda Diamond League meeting of the season in Rabat on June 5th.
Warholm, who shattered the 400m hurdles world record at the Tokyo 2021 Games (45.94), is aiming for a third successive Diamond League title in 2022, having taken the trophy in both 2019 and 2021.
Last season, the Norwegian broke what was then a world record of 46.70 at his first appearance of the season on home soil in Oslo, before going on to improve the mark at the Olympic final in Tokyo.
