Operational tasks include organizing home bouts, organizing fundraising events to offset the cost for operating the league, promoting the sport of roller derby, recruiting and training skaters and volunteers, among other tasks necessary to run a business.

MRD started in March 2006 after two Portland women were inspired by the A&E reality show Rollergirls.

By June 2006 a group of twenty women began holding weekly practices at Roller World in Topsham.

Determination and hard work (along with advice and support from skaters within the roller derby community) resulted in the launching of the Sneak Peek, the introduction of modern roller derby to Maine in November 2006.

Since then, the league has hosted a season each year, inviting teams from all over New England, Canada and as far as Ohio to play at the Expo.
