I agree it takes a hell of a lot longer to travel anywhere than you might think, from my experience. But It does depend on what you want to do. If you want to see a country and its people etc... the real deal so to speak, the motorways are not where it's at. If you are just going through ( transit) a country or two then that's fine I guess.

For me off the beaten track appeals even when I transit a country, slow roads / bad roads / local speed limits and so on all add up to make it take longer than you think, longer than Miss Tomtom or Mr Garmin think.

Personally looking at your plan and the miles you "hope" to do in a day it would be my idea of a wasted trip anywhere. What do you hope to see in this time? It looks to me like all you will be able to do is ride your bikes on a road, eat some dinner, drink some , go to bed. I would pick a country and spend some time in it. I suggest Croatia, it's a fab place to explore. Then next time pick another country. 15 days actually is not much time for your plan, as pointed out already.

If however all you want to do is ride and tick off a few countries........then it looks like a plan.........

Thanks for the answers guys and JimLad that is a really nice read, your RR..special thanks for that.
I hear what you are all saying as regards the distance and under normal circumstances would also agree. It is definaltly a bit of a mental idea, but hey ho:-)--- We would normally only do about 300kms / day but this ride is different... Yeah we're doing about 15 countries in 15 days but we just love riding and wether the 7000kms is done touring Norway or crossing borders it's still the riding we're in this for. The marathon element is helping us hopefully to get more sponsorship for a charity aswell so that's also pushing us. As I mentioned normally I would spend less time in the saddle and more on the sights but this tour is intented to be a different kind of ride and the challenge is all part of the fun:-)
Having said that we are planning that the last 2 days of the trip from Slovania up through Austria and back through Germany will be via better quality transport roads where we will cover about 800kms / day which will give us more time in the other countries which are new to us. Likewise we will be doing approx 800kms the first day from Denmark, through Germany and into Poland. This means that of the roughly 7000kms we have planned we can dispatch about 2500 of them in these 3 travel days. That leaves us with approx 4500kms left for the other 12 days ( roughly 400kms/day) which should give us a lot more time to enjoy:-)
Again many thanks for your answers and the time you have used on them. As the trip develops I will put up a few updates:-)

Dont want to rain on your plans but forget high miles in germany , certainly across the middle of the country - did that last week and the autobahns were nothing but roadworks , will be nice when finished though . We mainly used 3 from Leuven thru to the Austrian border - tailbacks were appalling too . Romania will be slow going as well im afraid ............... we met three Polish guys in Hungary who were heading to Istanbul and reckoned they could do it in two days incl the transalpina and transfaragian passes They are probably still not there !! I think three hundred miles a day is a big day in eastern europe - and i am usually a mileage monster ( 600 - 700 miles at a time ) but there are no motorways , or those that are there arent finished and there are tons of trucks too . As everyone else has said , less will be defintely more

Thanks for the answer Chris.... I travel a lot in Germany with my work and the I've done the Munich to the Danish border trip twice in the last 3 weeks and yeah there are plenty of roadworks and tourist traffic, but Germany in April is a different story and the 1100kms from Munich to Odense (Denmark) takes roughly 10 or 11 hours that time of year both on in a car and on a motorcycle.
As for Eastern Europe yes this will be a challenge but roughly 400-425kms a day will be doable that we will make sure of one way or the other and that is why we are doing are best to iron out as many potential problems and hold ups as possible before we leave. I really appreciate your answers thanks. :-)
