This isn't an Olympic event, but it's just as entertaining. Swiss skier Fabian Bosch did a pretty cool escalator stunt inside a building in PyeongChang. Instead of getting on the normal way, he stood NEXT to the escalator and grabbed the handrail.
And then he hung on with a straight arm as it rose up. When he got to the top he simply boosted himself over a small wall . . . because he's an Olympian.
