Karsten Warholm: A Viking word record holder who likes to unwind with Lego projects

Karsten Warholm (29) lives his life between two worlds. In one of them, he is the charming, easy-going guy next door, a real teaser, maybe a couple of minutes late at times, and always up for hours-long jacuzzi sessions with his coach Leif Olav Alnes (68). In the other life, he resembles a fearless Viking, who always storms out of the starting blocks as if he was embarking on his last 400m h race. At Weltklasse Zürich, the world record holder, defending world champion, and 2021 Olympic champion plans to make amends this year.
