Puma has signed a long-term endorsement deal with Karsten Warholm, the current world champion in the 400-meter hurdles. Now 23, the Norwegian athlete began with the octathlon and decathlon, winning gold at the World Youth Championships in 2013 and silver at the European Junior Championships of 2015 before taking the gold in the 400-meter hurdles at the World Championships in London two years ago. In June 2019, Warholm broke the European record in the 400-meters, and this month, at the London Anniversary Games, he broke it again.
