The Lucas Oil Pro Motocross Championship, sanctioned by AMA Pro Racing, features the world’s fastest outdoor motocross racers, racing aboard the best bikes each factory offers, on the roughest, toughest tracks in the world. Motocross racing is survival of the fittest as well as the fastest every weekend; it’s where legends like Ricky Carmichael, Jeremy McGrath, James Stewart, and Ryan Villopoto were built.

Motocross is the original extreme action sport, and Lucas Oil Pro Motocross is the pinnacle of pure motocross. The 12-rounds series begins at Hangtown in May and ends at Lake Elsinore in August. It includes stops at the premier motocross racing facilities in America, with events in Colorado, Tennessee, Massachusetts, Washington, New York, Maryland and Michigan. The pro riders meet up on Saturday afternoon, with competition divided into two classes: one for 250cc bikes, and one for 450cc machines. WMX racing will be hosted at three select rounds this summer, with the Hangtown Motocross Classic (Sacramento, Calif.), the High Point National (Mt. Morris, Pa.) and Moto-X 338 National (Southwick, Mass.) selected to compose what will be officially known as the Women's Pro Motocross Triple Crown.

Each track presents its own unique blend of jumps, hills, corners and whoops, but all the races run under the same format: two thirty-minute-plus-two lap motos (races) per class, with the scores from each race combined to determine the overall winner. The competition also tests fitness, as motocross at this speed is arguably the most physically demanding sport in the world.
