I'm 17, and planning on going a bicycle tour of Europe in my summer holiday (by which point i'll be 18). We want to cycle from Munich to Paris, via Berlin and Amsterdam, roughly 1000 miles, at around 50 miles a day. We also intend to spend three full days of rest at each city. So we'd be cycling for 7/8 days in a row between Munich to Berlin and Berlin to Amsterdam. I have never done extensive touring before, but intend to begin getting into shape for this tour soon via a gym. I just need to know: is this a feasible distance and a feasible rate of travel?
Any help is appreciated, cheers.
