You cycle on bike trails, ways alongside a dam, and partly on relatively quiet side roads. Busy roads are of short-term duration. You cycle on unmade paths only for 3 short distances otherwise you will find asphalted roads. On the whole, the route is signed very well with a few exceptions in the Slovakian part. Altogether the tour is relatively easy with slight increases in some sections. Because of the longer stages, you should have stamina.!
