The Grenzloipe takes its name from its location close to the border to nearby Italy. Beginning at the start in Sillian, the slope proceeds, climbing slightly to the state border, proceeding from there in short climbs and easy descents to Innichen. The slope may of course be tackled in the opposite direction. Starting from Innichen the Grenzloipe proceeds with just a short climb to the state border and continues, slightly cropped, through the partly forested area to Sillian.
