Baltic Mediterranean Run 2011

So I'm thinking the Baltic/Adriatic run is probably going to become the Baltic/Mediterranean Run. It's the same kind of thing. I'm just moving it a bit west, that's all.
Starting from Kaliningrad and heading down through Poland and what? the Czech Republic? Slovakia? towards Venice was a very attractive idea but when I bought a couple of maps of Poland to start planning a route I realised I might be stretching my navigational skills a bit too far. I don't even know the capital cities of some of the countries I was going to be traveling through. I mean back in 2009 when I was running from John O'Groats to Lands End I found it easy enough to get lost in Yorkshire.
If I start from Kiel and head down through Germany towards Genoa then I can follow European walking route E1.
It's a long distance walking route so there should be plenty of off-road hiking trails suitable for running, there'll be signposts, it goes through places like the Black Forest. There's even information about it on the internet. All the information I've found so far is in German or Dutch. But that's fine.
Now, the big advantage of taking the E1 is that I have a route to follow. The disadvantage, I'm guessing, would be that Germany has to be more expensive that Poland.
Here's a thing. I could save a lot of money by cooking my own food. But a camping stove, or rather the fuel, is a heavy item considering how lightweight I like to be. I have got the bivvy bag which I have yet to try out. If I could go with the bivvy bag rather than the tent I save over three pounds in weight. That would allow me to take the cooker. But is it realistic to sleep in a bivvy bag for thirty or forty nights? I dunno.
