mines all that exiting furthest was arad couple of years ago just before they joined eu my first and ony time out of eu
one of the regular runs i used to do was, load at risley then race over to hull to get the night boat to rotterdam,
rotterdam to bremen, get tipped out and park up to reload in the morning for milan.
tip milan and reload beer for anywhere down south, tip that out and then into teverola near naples to load
teverola to corby, tip out and run up to risley and start again, used to do 3 of these then go home for a break.

The longest single trip I took was frop Palmela in Portugal to Elk in Poland with car parts for Dawoo about 3500 km, but that was part of a trip that had me away from the UK for 4 1/2 weeks first loading from Dagenham to Palmela, then from there to Elk, then Elk to Bremen in Germany, then Berlin to Milton keynes. a total of over 8500 km
I just beat my longest, London to france, 8 tips in spain 1 collection then 3 tips in Portugal, then off to Vienna, tip there then go to Switzerland to load in 3 places, back to Uk where i still have 2 tips to do before going home 10376 km so far…Been out since the 3rd of Jan
Start Swiss; tip Madrid ;empty to Murcia ; empty to Lerida ; tip 2 in Austria ; tip Berlin ; load Frankfurt ;tip 6 drops Swiss. But that was not the longest distance by any means. I loaded pears in Lerida & was told to come towards Swiss on the old roads & to take my time as the pears hadn’t been sold as yet so there was no real destination. Lovely trip in Summer down Memory Lane stopping & getting off my face then kipping at every Routiers en-route. From Junction 49 / M40 to Casablanca empty only to be told when I got there that the load had been cancelled ! ( Dutch cow in the Tangiers office !! )
I seldom went to Italy…three or four times. First time they wouldn’t let me in because my driving licence was at the DVLC having points put on it for a bald tyre, (thanks, boss 
), once when I flew out just before Xmas to double man a friend back from Rome so he could see Xmas in the uk, once when I was hijacked, and once over easter where we got locked in a compound for 4 days…I kind of fell out with the place after that…
