The invention relates to a harness safety system that can be used while riding, for example, a skateboard, a bike, rollerblades, etc. through a half pipe. Specifically, the invention comprises a track spanning the half-pipe having a free-running cord and harness hanging therefrom that allows the rider to proceed through the flats and up the transitions of a half pipe while retaining tension on the rider throughout the process and arresting the rider's fall, thus preventing the rider from serious injury.
