People all over the world compete in a game called Ultimate, a non-contact team sport that's played with a Frisbee like disc. Two teams of seven play on a grassy field measuring approximately 110 yards (100 meters) by 40 yards (37 meters) with marked end zones. About 100,000 people -- both professional and casual players representing more than 50 countries -- play the sport. In America alone, there are more than 31,000 members of USA Ultimate (the sport's national governing body).
Participants are drawn to Ultimate for the intense cardiovascular workout it promises, as well as its friendly, inclusive culture. Although it can be fiercely competitive, Ultimate is civil and collegial.
Ultimate's rules are enforced by an honor code, and the sport is completely self-refereed. Even at the World Championship, Ultimate's premier competition, there are no referees, and the players themselves are responsible for making their own calls.
