While we may not have traditional high school sports teams at Duncan, those who enjoy athletics and competition will find a lot of different activities and sports to participate in. Intramural sports are played during lunch with sports such as Volleyball, Basketball, and Soccer. Teams are co-ed, include teachers, and comprised of students who share a homeroom. Games are played in a round robin or double elimination tournaments. The Championship game is usually played during homeroom in front of all the homerooms that were involved in the tournament. Winning team receives a class trophy and shirts for the players. On days when there are no games, students enjoy open court in the gym with basketball or volleyball.
