The RAT rally is an evemt put on by the Motorcycle Tourer's Forum every other year or so. I used the RAT route and mandatory checkpoints for a Iron Butt Rally training event. It is a realistic operational environment for IBR training to practice level of effort tasks, bonus collection and documentation tasks, pit stops and rest management tasks. See the Garmin Connect profile of the RAT statistics and RAT track created by my zumo 665.
