The 20 red runs in the Alps with the steepest stretch. Top is Kamikaze at Paradiski, reaching 60% (31°) over 50 m. By the ATUDEM and AFNOR criteria, over 40% is already black-run terrain.
For every official red run of at least 300 m, its steepest 50 m stretch, measured with the elevation model (about 30 m precision, smoothed against false spikes). Stretches over 60% are left out: on a piste they are usually a drop beside it, not the run.
