What it is ??? :
A crazy ice-skating/boardercross combination race called Red Bull Crashed Ice that defies logic and description is run annually, and this year it's in Quebec City, Quebec
It runs on a 430-meter course with a 60-meter total vertical drop that starts from the famed Château Frontenac Hotel, overlooking St. Lawrence River, and zig-zags through the streets of Vieux-Québec (the old city). The course features is described as a "demanding urban ice course that features whoops, berms, turns, curves and steep chutes.
This year, over 75,000 fans line streets of Old Quebec to witness Kevin Olson of Lethbridge, AB, win Red Bull Crashed Ice, a combination of hockey, downhill skating and boardercross
