Is it possible that the teams take an overnight train from Turin to Fussen, Germany? I was checking out train travel, and you can prebook that trip. This would also act as an equalizer for the teams.
I see that it may have been identified that the Ice Rink is in Fussen (Roadblock - Curling, where teams get their traveling gnome).
Hohenschwangau Castle, Schwangau, Germany is about 12 minutes away, so is the castle a Route Info versus a pitstop? And this is where the snowy labyrinth occurs (walking up to the castle)?
Gemeinde Unterammergau and Oberammergau is a half hour from the castle, as we see teams driving with the gnome.
And the pitstop is near those towns?
Just a thought, since driving from Turin, Italy to Fussen is a 6 hour drive and has multiple TOLLS.
