In order to create a course you need to first create a free user account. Once you create an account you can Log In and create a course. Once a course is created you can enter a goal time and get the splits based on the terrain. If you have a Windows Mobile PocketPC you can download the course and target race and race against your goal time.

You can get audio updates every 10 seconds and hear how far ahead or behind your target pace that you are. You can also define intervals, feed zones, summits, and turns on the course.

It's fun and easy, so give it a try!
