303 Roller Derby Partners


303 Roller Derby is proud to participate in a tri-league partnership called SuDERBYa. SuDERBYa consists of 303 (Lakewood), High City Derby Divas (Aurora), and Castle Rock ‘n Rollers (Castle Rock). Members of any SuDERBYa league may participate in any of three leagues’ practices and scrimmages at no additional cost, and may potentially be considered for rosters for any of the SuDERBYa leagues’ games.
