Fierljeppen is a traditional Dutch sport and one of the most complex athletic sports known to date.

A jump consists of an intense sprint to the pole (polsstok), jumping and grabbing it, then climbing to the top while trying to control the pole's forward and lateral movements and finishing with a graceful landing on a sand bed. Because of all the diverse skills required in fierljeppen, fierljeppers are considered to be very complete athletes with superbly developed strength and coordination.
