I have a a few loops around the streets of the little town where I live. Even though I live on top of a hill (which can make my runs more challenging), there are plenty of permutations to stretch or shorten my routes. Most of the time I lazy, but sometimes I’m not.
Having a few routes in your repertoire is never a bad thing. In fact, for the Lazy Runner, this gives you plenty of chances to be lazy, but still get a good run in. I also find that knowing exactly how much time and effort each route will take, helps to overcome your laziness.
