Armand and Johanna Duplantis will both compete in the Finnkampen this weekend. For Johanna, it will be her debut in the Swedish national team.
After the announcement of the selection, when the pole vault siblings warmed up together at the Stockholm stadium, SVT wanted to interview Johanna - but then Armand stopped it.
Instead, he himself answered questions about how it feels when the classic athletics international competition becomes a family party.
It's a special feeling. It feels very exciting. I feel so psyched and it's fun for the family that I'm competing with my little sister.
Armand Duplantis competes on Saturday. The day after is Johanna's turn.
Of course, I can help a bit with coaching, but I think the most important thing is to just experience these big competitions. You have to throw yourself into the fire, says Armand Duplantis.
