Pig-carrying races have been held in Oregon for 100 years. The tradition began when a piglet escaped from farmers and they decided to turn its capture into a tournament. 
Pig-carrying races are unusual competitions in Oregon, where local families have been competing for generations for 100 years.
Participants race in Ford Model Ts, which have been preserved since the first race in 1925 and are passed down from fathers to sons.
Each of the three circles, the participants must stop and change pigs.
