The cyclists start on the Rathausstraße in the centre of Naturno at 554 m above sea level and cycle along the asphalted street up to the Linthof (first refreshment point) at 1,464 m. From here the trail continues uphill on a forest road towards the mountain hut Dick until it reaches an altitude of 1,651 metres (km 11.1 of the MTB route) and then into the valley to the Fuchsbergstrasse above Innerunterstell. After a rather fast, 6.5 km long descent on the asphalted Fuchsberg road, where great caution is required due to the potholes and cracks in the asphalt and the many tight bends, the bikers reach the "Hof am Wasser" at the bottom of the valley (888 m). From there, the route continues uphill again along the main road to the ArcheoParc in Unser Frau (1508 m), where the first change takes place. The second refreshment point is near the turn-off to Karthaus.
