Starten in Kallbäck/Hälsingbo and rounded east side of lake Grycken clockwise before passing Silfhytteå and going north towards Ängelsfors. Stopped for water in Silfhytteå twice, which thankfully had plenty of water in the well even though there had been no rain for weeks. The only other options for water would have been the small store in Stjärnsund or the campsite Edsken (for supported/self-supported runners).
Thankfully plenty of places to access the lakes for some cooling off.
The trail is easy to run, mostly gravel roads and not that much elevation. Only one long hill a few km before Ängelsfors.
It was quite easy to find the way using a map and super easy with a gpx-track.
