An on-call person hired by the venue or promoter to drive errands and pick up anything the touring crew needs during the day: coffee, food, replacement gear, last-minute hardware-store runs, airport pickups. The runner is a critical hospitality role: a good runner makes the day flow; a missing runner means the tour manager is driving themselves to the gas station for emergency drum sticks. Always listed as a line item in the hospitality rider for non-walking-distance situations.
