Race directors or others submitting events should appreciate this.
Don't like not knowing what the Google map of your event is going to look like until after you've submitted your event to the calendar? Problem solved. Now, after you've entered your event's address, you will find a "Preview map" button. Click on this button and a map preview will appear. If it's not what you would like to see, you can go back and adjust the address. Click the preview button again and the map preview will update. Once the map meets your approval, simply continue filling out the rest of the event information and submit it as usual.
I hope you will find this useful in ensuring that your event page is displayed precisely as you want it. I would strongly suggest that everyone previews their maps before submitting their events. That way, you can ensure that the maps are as accurate as possible and entrants will be able to easily find their way to your events.
