Cinder track

A cinder track is a type of race track, generally purposed for athletics or horse racing, whose surface is composed of cinders. For running tracks, most cinder surfaces have been replaced by all-weather synthetic surfaces, which provide greater durability, more consistent results, and are less stressful on runners. The impact on performance as a result of differing track surfaces is a topic often raised when comparing athletes from different eras.

Synthetic tracks emerged in the late 1960s; the 1964 Olympics were the last to use a cinder track.

The Little 500 bicycle race at Indiana University is still run annually on a cinder track.
