What he tries to achieve?
Today's average XC race speed (for men) is above 7 m/s, downhill is about 10-18 m/s. In (Spring, 1988) we can read: "If the best gliding skis are to be chosen only velocities over 5 m/s should be used, because gliding differences are best observed at higher velocities". The guy in the movie looks to have gliding velocity below 1 m/s. What he tries to achieve? References Spring, E. 1988. A method for testing the gliding quality of skis. Tribologia, 7, 9-14.
