Roller derby has been around for years!
Predominantly a women’s sport, it stems from banked track marathons played in the 1930’s. Modern roller derby resurfaced in Texas in 2001, as a fast paced, contact sport.
The rules are simple; stop the opposing jammer getting through and scoring points. You do this by contacting opposing players using specific ‘blocking’ areas, hopefully knocking them down or off track. The team with the most points at the end wins!
