The quadrennial Rugby World Cup (RWC) is an integral part of increasing rugby participation worldwide. In order to leverage the RWC to create a desired participation legacy, strategies must be strategically integrated into the planning, monitoring, and evaluation of the event. From this perspective, The Lead Up & Legacy Strategy of the 2015 RWC provides one of the most well-developed leveraging plans to date. This chapter provides a comprehensive overview of the plan, which focused on two primary areas: (1) building capacity and (2) increasing participation. The legacy impact within these two areas is briefly reviewed, and the discussion integrates these results within the broader literature on leveraging and legacy.
