There are two governing bodies, AKIS and MSIS that have governance over this event. Both of these regulatory bodies have basic competition rules applying to the sports within their jurisdiction. You should be familiar with these basic regulations. You do not need to know both, just the set that applies to you and the vehicle you will be using.

- MSIS for Bikes and Quads www.msisport.is Motorcycle and Snowmobile Association of Iceland
