I do the same... sometimes I even switch my route just for a change of pace.
When I was building up my fitness I was quite careful to research my routes and avoid steep grades or excessive up & down... now I don't really think twice about moderate hills (<5% for <30m = 100ft of elevation), and know I can do larger hills (up to 12% grade and ~120m = 400 ft elevation). Larger than that is a mountain, and you kind of know where all those are.
