Just less than a month to go before we set off. The plan is to follow the Rhine up to Breisach and then climb up through the Black Forest to Donaueschingen. Crossing over the watershed to Villingen to the Neckar spring, we'll follow the river down, past Heidelberg back to the Rhine at Mannheim. From there, we'll head West to Saarbrucken, and continue down the Saar to Konz where it joins the Moselle until we, once more, rejoin the Rhine at Koblenz. Next, its cross country to Duren on the Rur which we'll follow to Roermond and its confluence with the Maas, and thence, back through North Brabant to Rotterdam. Generally we'll plan on covering 50 - 60k per day, but none of this is 'set in stone' and may change as we go along.
As far as preparation goes, to be honest, there's not a lot left to get ready, now that the rail tickets to Hull and the Hull-Rotterdam ferry tickets are booked. After our experiences cycle touring in the past we have already assembled all of the kit we'll need.
