Parkour wall running starts

Running starts have been part of the competition scene but it has never really taken off outdoors. The parkour world record in wall running is 4 meters so you could just imagine what such specialists could do putting several pads in a row and just wall run up some 8A slabs. In practice, taking two steps back and go for a dynamic jump start might be a possibility to avoid some start cruxes. On the other hand, such starts raise some ethical questions as some will not call wall running ascents as bouldering but instead parkour. Furthermore, in reality, when it comes to especially sandstone and limestone, the shoes must be absolutely clean as otherwise such footholds could quickly become polished.
