Mario Kart in the Alps

Mountain biker Sam Pilgrim teamed up with the Swatch Nines alpine sports crew to race down a mountain in Sölden, Austria. Their three-wheeled carts are not motorized, just gravity driven, but they reach ridiculous speeds as they make their way down the hill. They have brakes, but no one is using them. Pilgrim wears the GoPro camera. Some of them are wearing Mario Kart costumes to lend an air of, uh, inauthenticity? Meanwhile, you might notice that the road is ridiculously narrow in places, and there are few guard rails to keep a rider from tumbling down the mountain.
