Throwdowns lets you share the venue name and street address for your competition.
To set your competition location:
Login to your organizer account
Select "Manage" on the relevant competition
Select "Marketing" then "Time & Place"
Fill out "Venue name" and "Venue address" fields
Filling out the address generates a map preview showing your venue location
When you specify the address, Throwdowns also includes a map and the ability for participants to get driving directions from the bottom of your competition's public page.
If you are having trouble getting your address to appear in the "Venue Address", it might be the case where Google Maps is having trouble finding the address you provided. Try pasting your address into Google Maps and copying the address it returns.
