I did a supported cross country trip in '08, and there was a week where we had no rest days and about four centuries in a row. It's doable (heck, I did it), but it leaves no time to do anything but sleep, eat, and try to get from point A to point B.

I understand the need to do the one 135 mile day, but I'd try to make the other days shorter and more fun. Take your time, see things along the way, and hope that she'll want to tour again with you!
