Muswellbrook and Districts Roller Derby League (formerly Valley Roller Girls) was founded in 2011 by a determined group of like-minded ladies, interested in playing the worlds fastest growing sport of Roller Derby. MAD Roller Derby members are based in the Muswellbrook area and surrounding districts such as Denman, Singleton, Aberdeen, Scone, Jerry's Plains and Broke.
MADRDL is a not-for-profit sports league run by skating and non-skating members, promoting sport over spectacle in a fun, supportive environment.
