That seems like sound advice. Actually the tour won't be all that demanding. We're allotting a couple weeks just b/c we can...which means that we could do as little as 50-60k per day and still be able to more or less take our time and enjoy everything around us. Supposedly the route isn't too challenging hill-wise so that shouldn't be a problem. We chose the route though as (1) it leads down to the German-Austrian border allowing great views of the Alps, (2) you don't have to actually climb in the Alps, and (3) it's a circular route. Should be interesting.
Thanks again for that info...it'll make the wife feel better! :-)
