In the first year of the IBMXF World Championship in 1982 after having your standard racers to decide the World Champions in the various Classes, both Amateur and Professional, an overall World Champion was decided by racing all of the class winners including the Pro Champion and Amateur champion in a single race called the Trophy Dash. In 1982, Greg Hill, the professional World Champion refused to race the Amateur World Champion the American Nelson Chanady, claiming that there was no point to it. Nelson Chanady raced and won the Trophy Dash without Hill's participation, capturing the Overall title. However, since Mr. Hill did not race, the World Championship title lost a considerable amount of luster, since American professional racers were regarded collectively as the best in the world with Mr. Hill being among the best of them. Because of this loss of stature due to Mr. Hill not racing that final race in 1982, the Trophy Dash to determine the World Champion was abolished and in 1983 when the American professional Clint Miller won the World Professional Championship he was also considered the overall World Champion.
