Hi Mike
Sounds like you’ve a plan
I did a route similar to yours three years ago. I ended up doing 4360km in 10 days, and my furthest point south was Monaco. That was a beautiful place, riding the start finish line of the F1 grand prix, not forgetting the tunnel. Thing was, after setting myself a stupid schedule I only had about an hour sitting in the harbour, with a Mars Bar and a coffee.
Then, It was find my P***ed off pillion (a female with a sore ass) to start the long haul home. I got back to Portsmouth and wondered what the hell I did it for? It started a bit like yours “take each day as it comes” but, you’ve already got a tick list in your mind, and you’ll end up trying to do it. Sounds like a nice ride BUT give yourself extra time, about a week or two. You just won’t have time to stop and enjoy. Always laying down miles, and most will end up being on the Autoroutes.
You want to do the Ring. Then, I suggest you do it, but spend all your time in Germany. I did it last year after deciding to revisit each place I didn’t have time to stop at. Germany is full of good biking roads, the people are nice and the food and

are good.
Whatever you end up doing, have a nice one m8

Regards
Shaun
PS: note about the ring, most days it opened at 5:15pm while I was there. They also have a nice track side B&B bout 45 euros a night I think. Biggest Tip….. Watch Out for the fast stuff coming up behind you. Enjoy your lap

mine was 12min 25secs from the car park.
