Recognizing the importance of timing in efforts to drive institutional change, this study examined how actors engage in “temporal institutional work” in their attempts to disrupt inequitable institutions in sport. A qualitative case study was conducted on football (soccer) in Australia wherein significant gender equity reforms have been enacted. The findings revealed how the temporal activities of entraining (e.g., capitalizing on external interventions), constructing urgency (e.g., through advocacy), and enacting momentum (e.g., through consensus-based leadership) allowed actors to exploit a time-sensitive window of opportunity for change, quickly foster a perception of irreversibility that structural change would occur, and generate synchronicity with broader reforms. Inspired by the breakthroughs in Australian football, this research highlights temporal-based strategies for combating gender inequity in sport. Theoretically, this study extends research on institutional work in sport by illuminating the key role that timing norms play during institutional change.
