In the region around Hausach, Schiltach and Hornberg most climbs include an extremely steep section. This ascent forms an exception to this rule because even the steepest 500-meter interval (10%) causes no problem for the true climber. Because the number of elevation meters (514) is also limited, this is, alltogether, a pleasant climb. The first four kilometers of the trip run through the Untertal, where Kirnbach is located. In this village the road gradually becomes steeper. Shortly after leaving the Untertal, after a sharp left turn, the steepest section of the climb starts. This is also the beginning of the Obertal. Here one bikes through a beautiful landscape with forests, meadows and farms while the gradient measures about 8%. The last one and a half kilometers before the finish at the fork near Gasthof Mosenmättle are easy (2-6%).
