Cousin used to be part of a hip hop dance troupe. The longest routine I can think of was a 15 minute medley during which everyone on the team had a chance to take center stage at one point or another. She danced for maybe 8 minutes total with the rest of the routine having her essentially acting as set dressing while other peeps did their thing. Her pieces where she was constantly dancing were closer to five minutes max with her doing between 2-4 routines per competition.
