Motocross is a 12 race series starting in May and ending in September as it crosses the country.  Motocross races are conducted on closed dirt courses and have to be a minimum of a half-mile long and a maximum of 2 miles.  Toyota is the title sponsor of the AMA Motocross Championship for the third year in 2008.

The events are held in rural areas throughout America on natural terrain.  Held in the summer heat, the natural terrain is rough, rutted and treacherous, making these athletes among the fittest in the world.  Races take place on partially natural and man-made terrain consisting of steep jumps, difficult obstacles and multiple direction changes.

Each race is really a three-day affair, with many fans camping at the track starting Friday with the professional race ending Sunday evening.  There are two races, or “motos,” with the overall best results of the two 30-minute-plus-2-lap motos determining the winner.
