What exactly is roller derby? Roller derby is played on an oval track. Players called “jammers” attempt to pass groups of players called “the pack.” This involves somewhat simultaneous defense and offense, resulting in a great sport to watch.

Players skate on four-wheeled ("quad") roller skates, and are required to wear protective equipment, including a helmet, wrist guards, elbow pads, knee pads, and mouth guards. All current sets of roller derby rules explicitly forbid inline skates for players.

DERBY TODAY While it used to be predominately played on a flat track, more and more leagues are venturing to the banked track. Most derby leagues use a DIY (do-it-yourself) mindset as they are run by the skaters. It is common practice for leagues to participate in fundraising and community service projects.
