Parallel Slalom (PSL)
It is similar to Parallel Giant Slalom, but the actual speeds are slightly lower. There are more gates and they appear closer together, causing the riders to have to be quicker from edge to edge The parallel course must have a minimum of 120 meters and a maximum of 180 meters in vertical drop. The course should have a ground length of a minimum of 400 meters and a maximum of 600 meters. The same course may be used for men and women. The distance between turning poles must be between 10 and 14 meters. The distance between turning poles of a banana in a combination must be between 6 and 8 meters.. A slalom gate consists of one stubby flex pole (turning pole) and one long slalom flex pole (outside pole) which are connected by a triangular gate flag.
