Marching band practice consists of 1.5 hours per day, Monday to Friday out on Elbel Field. Each section generally also has a mandatory half-hour practice before one of those days. On game day, there is a two-hour practice, a "lunch" break, then a half-hour visualization session prior to step-off to the stadium. The NCAA defines a football game as 3 hours, regardless of how long it actually takes. That's a 13.5-hour week for the marching band.
