I may have exaggerated a bit. I think the 'rarely go far' part may have come out wrongly. What I'm saying is that I would probably not do a century without at least a few short stops. The stops may coincide with, say, buying raisins. Being diabetic, I often use raisins to keep my blood sugar stable. It was just an example.

Nobody directly suggested road saddles. I just have (had?) the impression that road bikes go with road saddles, partly because I reckon different riding positions demand different saddles. I don't care much about what sort of saddle it is, as long as it's comfortable. Weight, style, etc., are very much secondary considerations, of course.
