On my ride log on bikeforums.net, there's a category for "hilly", "rolling hills", etc, and I just leave it blank. If you're just starting or from the flatlands, every little bump is a major obstacle, if you're Mr. Beanz, then you don't notice that little 1000' hump in the middle of the ride. There's spots that I had to downshift and climb over when I first started that i don't even think about being hills now.
