** Note: If the runner icon is not located at the starting point of the event, adjust the map. You can make adjustments by dragging it or search for a new location using the find button. Once you center the runner over the exact location, click the save button. If you entered text in the “Specific Location/Address” field, that text will appear on your registration page.
