To set competition location:
In the Organizer Dashboard, click the Manage button on the relevant competition.
Under the menu on the left, select Marketing > Time & Place.
Fill in the Venue name and Venue address fields.
Filling out the address generates a map preview showing your venue location and shows it on the bottom of your competition's public page.
If your venue address isn't appearing in the list when you start typing, in most cases Google Maps can't find the address you provided. Try typing your address into Google Maps and copying the address it returns.
