Before you add a new hill, check to make sure someone hasn't already added the same one. You can do that by searching for the hill.

If you're sure it's not already uploaded, then start by creating an account. Verify the email that's sent to you, and log on. Now you will see a menu entry on the left sidebar called "Create hill". Click it and you'll find yourself on a page with a form to fill out.

There's a field for Hill Name and for Street Name. That's because one street may have many different hills on it that can be added separately, and a hill may not be on a street at all! Only the Hill Name is required.

To select multiple categories, such as different types of rides or difficulty, hold down the control key (CTRL - Windows PC or COMMAND - Apple) and click the options you want.

When entering city, please make sure you spell it correctly. If someone has already added a hill to your city, then it will appear on the list as you start typing. For example, if you are adding a hill in Durban, if you type "Du" and wait half a second, a list will appear with all cities starting with "Du", for example "Durban" and "Dublin". This will help you to choose the right spelling.

Try give a good description of the hill, image that you'd never ridden it and you were describing it to someone.

There are more specific instructions for specifying length, width and height on the rest of these help pages.

You can also upload your Google Earth data file. You can't upload one data file with many hills in it - you have to separate them out, so that one data file contains the paths, icons and placemarks for one hill only. This allows us to have very rich map data for individual hills.

Please see creating a map data file for help on creating these .KML or .KMZ files in a way that Hill Bomb can accept them.
