Conditions races are horse races where the weights carried by the runners are laid down by the conditions attached to the race. This article is about the sport For other uses see Horserace (drinking game or Horse race (politics. Weights are allocated according to; the sex of the runners, with female runners carrying less weight than males; the age of the runners, with younger horses receiving weight from older runners to allow for relative maturity, referred to as weight for age; and quality of runners, with horses that have won certain values of races giving weight to less successful entrants. Weight for Age (WFA is a term in Thoroughbred Horse racing which is one of the conditions for a race
Conditions races are distinct from handicap races, where the weights carried are laid down by an official handicapper to equalise the difference in ability between the runners. A Handicap race is a Horse race where horses carry different weights
Conditions races are staged at all levels of horse racing but races for the very best of horses are split into:

The pattern system, overseen by the European Pattern Committee, is fluid and the Group status of key races can change. By this method, the Prince of Wales Stakes at Royal Ascot was upgraded from Group 2 to Group 1 in the year 2000. Ascot Racecourse is an English racecourse located in the village of Ascot, Berkshire used for Thoroughbred horse racing. However, a number of checks and balances are in place which ensure that changes to the Pattern are gradual and evolutionary, thereby giving the racing industry time to adjust. In particular, the current European Pattern Committee "Ground Rules" explicitly state that no race may be upgraded by more than one Group in any one year. Such restrictions can prove troublesome when major new races are launched. For example, the Dubai World Cup, the world's richest horse race, was only given Listed status for its inaugural running in 1996. The Dubai World Cup is a Thoroughbred horse race held annually since 1996 at the Nad Al Sheba Racecourse in the city of Dubai, United Arab Emirates
The pattern system exerts a huge influence on the bloodstock market, particularly in relation to the fee that a stallion can command for covering a mare at stud. This will be dictated almost entirely by the stallion's performances in Pattern races during its racing career. Only the very best horses can perform successfully in Group 1 events and such animals invariably command the highest stud fees when their racing career is at an end. A top-quality stallion can be enormously lucrative for its owners - stud fees of more than US$100,000 are relatively commonplace for the most coveted stallions.
In North America, the best horses race in graded stakes races instead of conditions races. A graded stakes race is a term applied by the American Graded Stakes Committee of the Thoroughbred Owners and Breeders Association to a Thoroughbred horse race in The division is similar to that for pattern races in the rest of the world:
Unlike in some other countries, handicap races can be included in the North American grading system; several North American handicaps are Grade I, with more handicaps in the lower grades.
