The IBMXF followed the previous practice of holding a Trophy Dash race off between the fourteen-year-old and above classes (Expert, Open and Girls divisions but not Cruiser) including the professional winners and amateur winners racing against each other to decide the Overall Championship.

In a bit of serendipity on Chanady's part, Stu Thomsen was slated to be one of the pros to race, but due to an ankle injury suffered at a national in Memphis, Tennessee, as per prior agreement with race organizers in the event of a slot becoming available, GT had the right to choose the replacement.
