Maybe this is a silly question but I don't think I've seen any mention of it.

So what do you consider to be a tour?

Do you have to cover a certain distance?

Do you have to be away from home for at least one night, more than one night? If so is there a distance associated with the night out to make it a "tour"?

I could ride an hour away and camp out, but I would not consider that a tour. Likewise I could ride 100km and come home, but that's just a long ride.

What are your thoughts?

And to be clear, I mean a bicycle tour.
