To work and back home: ~6 miles by direct routes. I can stretch that to 9 if I take the lake to and from work.

If I'm visiting my daughter it's ~3 to work, about 8 miles to her house and 10mi. back home, adding 12miles to the "commutes" those days. If I forget stuff for my visit, I have to go home then head out, which is 3mi. home, then 20 there and back. These are not the shortest, but easiest/most direct that I prefer, if I rode without a time pressure, then I'd go by the lake and that'd be longer but much more pleasant (in summer anyway ).

So basically my ride to work and back is short as heck, but my life commitments mean I typically ride much more than just my work commute.
