FWIW-- I believe that bike tours like a lot of activities do not fit discretely into nice little categories. The different kinds of bike tours are a continuum ranging from fully supported, luxury tours to hardcore expedition riding. As an example, the demarcation between self supported and supported is not a precise black and white boundary, but rather a broad fuzzy gray area where the amount and type of equipment carried varies considerably. Just the term "self supported" could include a pretty broad range of situations. I think naming the different categories is relatively easy, but defining them is another matter.

I just completed a 3 week "fully loaded" tour and only camped 50% of the trip. The other 50% was CC. Does staying at motels, friends and relatives part of the time, negate the part of the tour that was "self supported"?
