Freiburg, Germany to Florence, Italy – any recommendations?

Dear cyclers,

I am planning to take my bike from my home in Freiburg near Florence to attend a wedding in August this year. I started planning my route today and just clicked around Komoot without a clear strategy. I'll bring my tent and try to pick between camp grounds and wild camping (if the situation seems appropriate) and want to arrive after 7 days. This will be my first multi-day bike packing trip, but I do quite some road cycling as a hobby, so I am hopeful that I am ready for such an endeavour 🙂

Any tips are welcomed, especially if you think my route should be adjusted because I'm taking a stupid road or I'm missing out on something.

My thoughts were to first cross the Schwarzwald and then ride along the Bodensee, cross Switzerland (I hope for some nice alpine views) towards Como. From there I thought about riding towards the Mediterranean and back inland towards Florence.

I hope the link for the route on Komoot works for anybody interested.

Thank you and keep on riding 🙂

Route in mind
