Some kilometers after I started there was a nice ascent to Fürstenberg with a mice view over the Danube valley. The way down was less steep, so I was able to cycle with a good speed. Btw the highest speed was 65 km/h today.
Then I crossed the steam line Sauschwänzlebahn (Pig Tail Railroad) multiple times.
As yesterday temperatures were pretty high speed again (37 degrees Celsius according my bicycle computer) , I had to drink am awful lot of water. In Switzerland they serve nice cooled water directly near the cycle path.
Between Lauchringen and Kadelburg Komoot routed me over a mountain bike path with a steep ascent on a gravel. That might have been shorter, but surely it took a lot more time and Energy. I crossed the Rhine an the Swiss border in Bad Zurzach and had a second avoidable ascent to the Aare Valley. So in future cross the Rhine in Koblenz; this leads directly to the Aare.
At the end of the day I found a campsite in Aarburg with an impressive Fortess.
Today I cycled 116 km.
