In the clip above, you can see how it went.
On Sunday, there was a so-called seeding race before the Gothenburg shipyard starting in Frihamnen in Gothenburg.
The participants would run ten kilometers, and their times determine which starting group they end up in at the race on 21 May.
But Hanna Skårbratt took the opportunity to make an attempt at a world record time - with her two pairs of twins in the carriage that she shot in front of her.
No one has the world record with just four children in a pram before, but the Guinness Book of Records still set a limit of 55 minutes.
