Beyer Speed Figure

The Beyer Speed Figure is a system for rating the performance of Thoroughbred racehorses in North America designed in the early 1970s by Andrew Beyer, the syndicated horse racing columnist for The Washington Post. First published in book form in 1975, the Daily Racing Form began incorporating Beyer Speed Figures in a horse’s past performances in 1992 and the system now assigns a Beyer number for each horse race. On the Beyer scale, the top stakes horses in the United States and Canada typically earn numbers in the 100s, while extremely strong performances can rate in the 120s. In Europe, Timeform has a similar rating scale that yields a number, but with a different value. The popular rule of thumb for a rough equivalent of the Timeform score is to deduct 12-14 points to achieve the Beyer figure. For American Quarter Horse racing, the Speed index rating system is used.
