Looking at the opening times of the Ring..... pretty much all of the touristfahrten sessions are just down as 'nordschleife'.
But the Saturday evening (28th May) is listed as 'Nordschleife & Sprintstrecke' - is this when they open the GP circuit up too so you can do a combined lap of the two?
If so, i'm liking that very much
