Board track racing was a type of motorsport popular in the United States during the 1910s and 1920s. Competition was conducted on circular or oval race courses with surfaces composed of wooden planks. This type of track was first used for motorcycle competition, wherein they were called motordromes, before being adapted for use by various different types of racing cars. The majority of the American national championship races were contested at such venues during the 1920s.
Board tracks proliferated in part because they were inexpensive to construct, but they lacked durability and required a great deal of maintenance to remain usable. Many of the tracks survived for as little as three years before being abandoned.
With the onset of the Great Depression in the early 1930s, board track racing disappeared rapidly. However, several of its most notable aspects have continued to influence American motorsports up to the present day, including: A technical emphasis on raw speed produced by the steep banking; ample track width to allow steady overtaking between competitors; and the development of extensive grandstands or stadium-style spectator seating surrounding many of the courses.
