The Mustang Cup is an opportunity for students to participate in a intramural-style competition that spans the school year. Students assemble teams of 7 (5 players and 2 alternates) and compete in various events held one night a month from January through May. Teams accumulate point totals for participation and performance, with the winners announced in May scoring a place on the Cup itself, plus prizes.

One of the goals of the Cup is to not be solely athletically focused, but to have a broad range of events that would interest many students. Over 250 students from all grade levels were polled to determine the events that would take place.
