Year Opened2010
Die Borderline wurde 2007 als erster offizieller Trail in Freiburg eröffnet.
Startpunkt ist am Rosskopf, von wo aus die Borderline nach Süden ins Dreisamtal zur Jugendherberge führt. Der obere Abschnitt ist steil und technisch anspruchsvoll, gespickt mit steinigen Passagen und größeren Stufen, die Fahrtechnik abverlangen. Weiter unten öffnet sich der Trail, wird schneller und bietet flowige Anliegerkurven, kleine Sprünge und seit 2025 auch eine neue Jumpline in Sektion 5 für extra Airtime. Richtung Ende sorgen steile, wurzelige Passagen noch einmal für Abwechslung.

Nachtfahrverbot – Trail ausschließlich bergab befahrbar. – Keine abgesperrte Downhillstrecke, Fußgänger möglich!

Im obersten Teil S3, danach dann entspannter.

Anno 2022 im Sommer ist das kaum noch blau, weil der Trail ziemlich ausgebombt ist. Macht richtig Spaß, aber ist stellenweise deutlich schwerer als blau.

Great trail that have started to erode quite a bit in some places,especially in the start and in the end. The sensation riding it is something between a natural trail and a badly maintained bike park.
For the grading - don't expect a blue run. The start and finish is for sure red, tech that is doable at speed and on-sight.
