Easy run from Flüelen to Muotathal through Chinzigpass. I'm still not exactly sure what the waypoints were, as I checked the Swisstopo map on my phone far more often than I should admit, but overall, I had a really lovely day. There weren’t that many people, and there were enough alpine restaurants to get a refill or drink something. Today was sunny and 28°C, therefore it was really welcome.
Worth noting that after a few kilometers, the route actually joins the first stage of the Tell Trail.
