The Sport of Motocross

Motocross tracks cover various terrain and expose the rider to changing weather contitions. The riders have to deal with long uphill or downhill slopes, deep mud and changing environments. Spectators have a hard time watching the entire race because of the size of the track. Usually they can only watch one section of the track at a time and can only see their favorite riders once every few minutes.
