The World BASE Race is not a race to the top, but to the bottom: 2,500 feet down a cliff! BASE jumpers from all over the world come to Rauma, Norway, to don wingsuits and compete, or just to watch. Unlike other BASE jumping competitions, this one is based on speed, with the winner being the one fastest to reach the bottom of the course in one piece.
