This chapter describes the nature and role of the two key players, the event owner and the event bidder, as well as the important relationships the intermediaries and agencies (promoters) play in the bid process. Through appraising the research associated with the stakeholder group, it provides an overview of the bidding process from different perspectives, and examines the key factors for success. Since sports event management imposes escalating challenges of sustainability, the normative aspects of environmental integrity and social inclusion is explored, drawing on real-life examples to illustrate current research and industry practice. The sport property owner has largely dictated the requirements of both the host and agent responsibilities and through recent initiatives increasingly accepted responsibility to ensure sustainable business practices are included in the bid documentation process. The chapter concludes with a summary of the bid literature and suggestions for future research for different stakeholders.
