When you go out to run errands on the weekend, you're on a "tour" as defined by human mobility researchers. Same if you book a guided tour of a famous city or take a trip on a cruise boat that reaches multiple ports. A characteristic of such tours is that you begin and end up in the same place and take intermediate stops along the way. The number of stops is the tour's "length."
