The Freundschaftslauf LT Rennschnecke Dudweiler is a running event in Saarbrücken-Dudweiler, held in the training area around the Gehlenberg in the Dudweiler Stadtwald. The start is at 3:00 PM, with runners directed to Rentrischer Straße 42 and then about 50 meters farther to the training ground. LTF Rennschnecke Dudweiler, a local running group, organizes the event.
The route follows the forest area around Gehlenberg. Past editions noted shade from the woods and tall trees near the festival grounds, beneficial on warm days. The event has a social focus: food and drinks are provided, and awards are given to the three groups with the most participants. Past attendance figures indicate a small, club-like field, with a notable visit of 13 runners on Pfaffenkopf. The race history includes at least one canceled edition.
