Bout, jammer, apex jump – if this is your first time hearing those words, you’ve been missing out. Roller Derby is a sport that rewards your curiosity. You don’t need to be able to spot a blocker in the pack, know how long a jam lasts, or how to perform a hip-whip to have a nail-biting good time at the Calvello Cup Championship. All this nickname-loving sport asks of you is a little courage and enthusiasm, which – trust me – once you’re watching 10 tatted-and-talented skaters aggressively maneuver around the rink and each other, you’ll be able to muster plenty of both. – Caroline Drew
