Roller Derby is a fast-paced contact sport played by women, trans and genderqueers on roller skates and was invented in the USA back in the 1930s. The game consists of a series of short match ups (“jams”) in which both teams designate a scoring player (a “jammer”) who scores points by lapping members of the opposing team.
There is no ball involved.
Copenhagen Roller Derby (CRD) was founded in September 2009 by Charlie Hedman. Charlie discovered the sport on a trip to the USA and gathered some friends upon their return to Denmark. Today CRD consists of 100 members with two competitive teams, as well as the Junior Roller Derby team, Troublemakers, for young people under 18.
