Took the gondola with Mathias to Schauinsland. The plan was originally to just do an out and back, but in the end we did a traverse to Hinterzarten. Ran mostly on forest roads, but a fair bit of single-track as well. First ran past the cross country ski facilities at Notscrei, then over Stubenwasen (1386 m) to Feldberg (1493 m). Long run through the forest down from Feldberg. Amazing experience to emerge from the forest into the small mountain village of Hinterzarten.
