If you are referring to the Great Glen Way, I find the description very misleading. Out of Invermoriston there is a steep climb, after Alt Sigh there is a steady climb of approximately two miles and from Drumnadrochit a pretty challenging climb. There are many other ascents and descents, mainly on forestry roads, not I would have thought suitable for touring bikes. As for "a fairly easy family pedal", fine if your family consists of Alberto Contador and Ivan Basso.
