The first part consists of seven pitches (about 300 m) with difficulties that do not exceed 7b, but many of them either do not have bolts, or only have one or two, meaning that you’re tested physically and psychologically since, in many places, falls are potentially very dangerous.
The second part consists of another seven more difficult pitches, very vertical and without rests, past continuous difficulties that peak with an 8c. As in the first section, bolts are runout and the pro needs backing up with trad gear. This was by far the crux. 
8 recorded ascents.
