Ooh that sounds fun!!! I'm guessing inline skates, but I know less about those, so I asked in this speed skating group I'm in! Do you/did you have your own skates in Sweden? Apparently ice skates can be converted! And they said there's lots of good distance setups and the difference is often $$, and also boot type (low cut or something with a cuff, whatever a cuff is!). I could try to put you in touch with one of the people in the group, or relay a few follow-up questions/answers :) In the meantime, here's a link they shared to some inline skates!
