Nelson Chanady became the first Overall World Champion for the IBMXF in 1982, its first World Championship event (the "International" Championship event held in October 1981 at the Pontiac Silverdome in Pontiac, Michigan is generally isn't counted). However, there was some controversy with this title. 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. This precedent was set by the Jag World Championships during the first three years of the four previous times the event was held beginning in December 1978 (which the NBL had co-sanctioned with the NBA the first three years), the Pro World Champion Greg Hill refused to race Chanady, the 17 Expert Champion and the other amateur champions for the overall title. His feelings this time where why should a pro race the amateurs? What is there to prove? At first the 14 & Over Open winner Andy Patterson tried to instigate a spontaneous boycott with the other racers, refusing to start unless Greg Hill joined them on the starting line. However, NBL Competition Director Robert Tedesco relayed to the other racers that Greg Hill's mind was set and he would not race. Tedesco urged the racers to participate without Hill. Accepting Hill's resolution, they agreed. With this Nelson became the first and last Overall World Champion. From then on the Pro World Champion is presumed to be the overall World Champion given the assumption that the Pro class is the most difficult and competitive class in BMX, as it is with any other sport. If you win the Pro Class you are assumed to be the Overall Champion.
