Roll out of Ruhla and let the ride unfold: past the Truse river, into the Naturpark Thüringer Wald, then castle after castle — Steinsches Schloss, Schloss Wilhelmsburg, Burg Frankenstein — before the Burgsee lake and Schloss Leimbach. The Werra river rounds things off, and 72.2 km later you're back in Ruhla. With 1006 m of climbing and almost all of it paved, it's a day that keeps giving.
