sports handicappers

Horse racing

An impost is the weight that must be carried by a horse in a race.[2] Horses carry lead weights during the course of a race as a form of handicap. Such a race is also sometimes termed a "handicap." These weights supplement a jockey's weight to give a horse his assigned impost. The jockeys use saddle pads with pockets called lead pads to hold the lead weights.

These riding weights are assigned by the Racing secretary based on factors such as performances, distance so as to equalize the chances of the competitors.

The weight for age scale was introduced by Admiral Rous, a steward of the Jockey Club. In 1855 he was appointed public handicapper.[3]
[edit] Predicting the outcome of races

In horseracing, until 1995, for pace handicapping purposes, the time generally allotted by pace handicappers for a horse to run a length (approximately 11 feet) during the course of a race was long thought to be a fifth of a second. This long held misconception was turned on its head by the works of Gonzalo Sandoval via his research into the internal fractions of thousands of Thoroughbred horse races. The resultant formulas and algorithms are what comprise his subsequent pace handicapping work called REXPOINTE Pace Handicapping. This method of pace handicapping is used by many fans of the Sport of Kings.


Thoroughbred handicapping is the art of predicting horses who have the greatest chance of winning a race, and profiting from these predictions at the horse races. The Daily Racing Form (DRF), a newspaper-style publication, is an important tool of the handicapper or horseplayer. The DRF details statistical information about each horse entered in a race, including detailed past performance results, lifetime records, amount of money earned, odds for the particular horse in each past race, and a myriad of other information available for casual or serious study.

The handicapping process can be simple or complex but usually includes the following elements prior to the race:

1) Study of the Daily Racing Form

2) Observing the horses’ body language and behaviour in the paddock and/or post parade, in particular, its ears and tail. Ears should work together and look forward or backward. The tail should be "quiet." A swishing tail indicates something is bothering the horse.

3) Watching the tote board for the changing odds of each horse and thus for clues about how the betting public views a horse’s chances of winning the upcoming race

“Trip Handicapping” takes place during the race and involves watching the horses (usually with binoculars) and noting relevant information about how a horse runs during that race.

Handicapping theory is possibly one of the most enigmatic theories in all of sports.[citation needed] Horseplayers consider the following elements when handicapping a horse race:

Speed Those horses who run the fastest, win the most races. The DRF lists times at certain call points of each race, and the lengths back from the lead at each call point. Speed handicappers compare race times to help ascertain which horses will most likely win the race. The DRF now contains a numerical summation of the speed that each horse ran in every race, called a Beyer speed figure. This number is generated through a method developed by Andrew Beyer, and described in his 1975 book Picking Winners. The Beyer speed figures takes into account the individual class of a race as well as how the racetrack was playing on a particular day to create an aggregate number for each horse. The basic error behind this approach is that the sample size each day which is used to create the track variant for the speed figure is very small, and hence subject to massive errors in standard deviation. For example, there may be only one turf (grass) race on a given day, and the Beyer system has to extract a variant for that race from a sample of one.
