Yesterday I went for a bit of trail running south of Uppsala.
I ran on the easy to follow (orange markings on the trees) Upplandsleden from Flottsund via Lunsentorpet to Fläktanstugan and back. Made for a total of 13 km of running on a pretty decent trail with lots of tree roots in the wonderful Lunsen forest.
Hopefully I can get hold of a map so I can go for a more circular route next time.
