Cinder track

A cinder track is a type of race track, generally purposed for track and field or horse racing, whose surface is composed of cinders. For running tracks, many cinder surfaces have been replaced by all-weather synthetic surfaces, which provide greater durability and more consistent results, and are less stressful on runners, although the surface temperatures can be much hotter (up to 147 degrees Fahrenheit). The impact on performance as a result of differing track surfaces is a topic often raised when comparing athletes from different eras.
