Very strenuous trail on which you have to pedal a lot. First it goes uphill, then flat to Hanskuehneburg. The trail is interspersed with many embedded stones. Quite wide in the first stretch and with good line choice and strength in the legs and lungs you can maintain a fluid speed.
Later the trail drops more, is relatively rocky, sometimes a bit loose, but there is always a smooth line.
In between there are a few nice vantage points.
