Podracing was a popular sport in the less developed regions of the galaxy. It has been called "the ultimate test of skill and daring on Tatooine," and was certainly one of the most dangerous sports ever invented.
Podracers were small, one-man repulsorcraft, composed of an anti-gravity pod propelled by one or more pairs of large engines. The engines were not physically connected to each other, being linked instead by power couplings consisting of plasmaturbine discharges. The engines were connected to the pods themselves by means of long, Steelton cables. 
The most famous podracing tracks are found on Tatooine.
