text: All American Futurity The All American Futurity is a race for two-year-old American Quarter Horse racehorses run at Ruidoso Downs Race Track in Ruidoso Downs, New Mexico on Labor Day. It is the last leg of the AQHA Triple Crown that has only been won once, by Special Effort in 1981. A $4 million bonus was once offered to the horse that could sweep all three Triple Crown races. It started in 1959, with a purse of $129,686.85. It has always billed itself as the richest race in American Quarter Horse racing, In 1978, the purse was over a million dollars and in 1982, the winner's portion of the purse totaled over a million dollars for the first time. The 2015 version of the race will have a purse of $3,000,000 with the winners share being $1,500,000, making it one of the richest races in North America.

text: 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, 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. Overall, the number reflects not only the winning time, but the time of the race and the inherent speed of the track over which it was run. On the Beyer scale, the top stakes horses in the United States and Canada earn numbers in the 100s, while extremely strong performances can rate as high as 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.
