Rating the difficulty of trails is at best an inexact science. In addition, adverse weather conditions tend to increase the difficulty of any run. If a scratch or dent in your 4×4 would totally ruin your day, you might want to take up golf instead.

  • All guest vehicles must pass a safety inspection.
  • Member vehicles will be randomly inspected. Be ready.
  • All participants must sign an Event Waiver.
  • Consumption of alcoholic beverages on any run is illegal and prohibited.

There are several run rating systems used by various clubs and organizations. SD4W uses the color method for all its runs except for at the annual Superstition Mountain event. We recommend that you read the event details for specific equipment requirements for that particular run.
