The Motocross of Nations is an annual team motocross race, where riders representing their country meet at what is billed as the "Olympics of Motocross". The scoring for the event works on the position system, i.e. first place is awarded one point, second place two, etc. Each class (currently MX1, MX2 and Open) races twice, each time against one of other two classes, for a total of three races. The worst score of three races is dropped, and the lowest combined score wins.
