Interest in the competition has spread internationally and the 42 places for the Swedish qualifier in Saltsjöbaden were taken in a week.

There will be participants from, among others, the USA, Canada and Spain.

- There are more participants than usual.

It's usually around 25-30 pieces so it increases every year, now it's starting to become a real sport!

"Will boil the water"

Last year, the organizer had to deal with corona restrictions and therefore broadcast the competition live.

As many as 60,000 people checked then.

- It is difficult to reach the same audience number, but I hope for three thousand people, it probably won't hold much more.

It's going to be such a hell of an atmosphere, it's going to be brilliant weather and it's going to be absolutely boiling in the water, says Adam Widén.

Best boy and best girl will advance to the finals held in Oslo on August 27.

- We have two sharp girls who compete.

They really stay at the top, they are so bent that they break the guys on the landing.

Watch some of the crazy jumps in the video.
