For those who didn't think rollerblading was hard enough, someone invented the intimidatingly difficult field of "freestyle skating." It involves a skater navigating lines of small cones that are spaced about 80 centimeters apart. Skating in between cones that narrow would be a feat to begin with, but freestyle skaters like to take it a few steps further.
There's a variety of tricks that skaters do while on their way from one end of the cones to the other. The following clip, taken from the 2012 World Freestyle Skating Championships in Lishui, China, showcases what a seasoned freestyle skater is capable of. Before you try any of these moves yourself, you might want to pick up some knee pads, elbow pads and a helmet. On second thought, let's make that two helmets ... just to be safe.
