>>2840131Please start with day hikes to get a feeling for your own performance first. Otherwise you won't know what's possible for you in a day. That's something you can do perfectly in Switzerland, since you're not dependent on overnight accommodations.
Use tools like Outdooractive to find the right tour for you. As a beginner, I'd stay below 2500m peaks and 100m of elevation gain per kilometer of distance (averaged), and below 600 meters elevation gain overall.
You will notice that a hike like this will require a couple of days of recovery in the beginning, making your original undertaking pretty unrealistic for you at first. You'd just be another person in need of help from overstrained mountain rescuers.
For multi-day tours I'd recommend Austria, South-Tyrol, Northern Italy or Slovenia.
But come and all again when you've done enough tours.
