Maybe you've heard about Roller Derby from some friend? Maybe you've seen it in USA or maybe you've seen Drew Barrymore's new movie Whip It?
I play Roller Derby in a new league in Malmoe. In general the sport is quite new in Sweden.
My league is called Crime City Rollers and right now we are about 45 players.
Roller Derby is played mostly by woman and on rollerskates, quads, not inlines. It's a full contact sport and you wear a helmet, kneepads, elbowpads and wrist guards. When we have full contact training or bouts you'll need a mouth piece as well.
You can read a lot about the sport here.
