I have no clue how far I travel in a day. I stop when I am tired, feel like stopping, or happen upon an interesting place. I usually start looking around for lodging around 4 p.m., if I haven't already found something. I get antsy if I haven't found a place to stay by 6 p.m. or so.
One of the reasons I tour without a bicycle computer is that I prefer not to keep track of distance and speed!
