If you want to refine it, we often name routes using approximate direction and distance too, which may help identify routes that don't start or stop in 'obvious' places. Example:
Home -> Elan 340Km NW
(Even circular routes often have a vague direction bias - as in they're not perfect circles.)
As an aside from auto-naming, it's also a good way to exclude routes with a quick glance (I don't want to do more than 300Km today - what routes can I choose from?).
