Long Way High

I am hearing voices in my head lately, not that I am a psycho or something and they urge me to do something terrible to change the fate of history, it's more like in the old cartoons where the little angel or devil sits on your shoulder gives you good/bad advice and obviously getting you into trouble. I cannot tell if it is an angel or a devil, it's always just out of my field of view so I cannot tell the color of his garment, nor do I hear flapping on angel wings or something. Anyway ... they tell me about a great idea I will try to accomplish next summer namely a bike trip from Budapest to Amsterdam.
So the facts: rough distance in miles from Budapest to Amsterdam is 713 miles or 1147.22 Kilometers
Let's calculate about 100 km / day that's 12 days at least and we have mountains to climb rivers to cross, sandwiches to eat music to hear friends to visit. I am thinking about the Berlin -> Stuttgart (visiting my ex N. :)) -> Amsterdam route. So in the next few days I buy a decent bike and start preparing myself for this. Wish me luck....
