The main aim of this study was to investigate the spectators understanding of the environmental impact when a sport event is hosted. The study focused on the Town Lodge Business Relay (TLBR) event, an annual event hosted in Port Elizabeth, South Africa. This event entails companies (corporates) entering relay teams, which compete again other teams. A quantitative approach was followed, using non-probability sampling and with spectators completing a self-administered questionnaire. The outcome of the study revealed pertinent demographic details about the spectators and indicated that most of the spectators (respondents) generally understood the environmental impact of sport events.
