The role of a runner in media production is an entry-level position that involves assisting production teams in various tasks. Common duties of a runner include answering phones, handling mail, organizing transportation, making drinks and light cleaning. Runners are expected to work long hours, remain enthusiastic despite repetitive tasks, communicate professionally with all personnel, and be strong team players with initiative. While the pay is low, around £200-£275 per week, the role of runner provides invaluable opportunities to network, gain experience in different production areas, and potentially find internal promotions after a few years.
