RollerCon is the largest roller derby convention in the world, featuring hundreds of games, hours of training sessions, and several social events. Held since 2006 in Las Vegas, the event hosts 5,000 attendees over five days on nine tracks—five for training and three for bouting/scrimmaging. Since 2015, RollerCon has added a banked track to its lineup. The current home of RollerCon is the Las Vegas Convention Center.
