Hi Swoop,
I drove past the Ring, about 6km away at one point. I have the GPS track I followed and I'll try and post it here tomworrow for you - my com port isn't working on my home PC so I'll have to do it from work tomorrow.
Basically the route really gets interesting if you look at a map - find Aachen in Germany then a bit south you will see about half way between Aachen in the north and Malmedy in the south a small town called Jalhay. From there I came up from the south east so you want to head due south east or about 5 o'clock on map. Pick up the towns of Botrange, Kronenburg, Stadkyll, Hillesheim, Daun (and Cochem if you want to go along the Mosel for a while) . I came across from the otherside of Frankfurt but you won't need to go that far as the Ring is close by the time you get to Daun. You won't be disappointed - I hope you guys get the good weather that I had because it really is brilliant biking country around there.
If you go for a drive on the Ring - be bloody careful - because there are some real nasty accidents there every year. Bikes always come off second to Porsches and other quick cars and in the free sessions the scarey thing is you can be blasting around a corner only to find a tourist coach in your racing line......you have been warned.
