Ritual/tradition has been used for sports in the past, such as "A non-contact sport or game - anything from carriage racing to golf!" during WE 2020. Related locations and organizations are prompts there that quite fit sports too. Participants could fit talking about teams/competitors, components and tools for materials needed, execution for the rules, observance for stadium info and such.
Ritual/tradition works well for sports, Organization for teams and sporting organizations (like the NFL or FIFA), and Conflict for a particular match (like the 2026 World Cup Final). A template for only sports/activities would be too specific and difficult to use in a more flexible way.
