Passau to Donaueschingen

Our 3rd book is finished, we do about half of the 600km distance, with a train detour at the start to our Schliersee holiday. The German Danube Bike Trail (Donauradweg) is hillier than earlier sections and less populated by cyclists, maybe because it's a bit late in the season. The headwinds are more prevalent but we push on and make it. The German language is slightly more familiar and the people we meet just as friendly.
