There are 13 horses that race in the Preakness Stakes.
The Kentucky Derby, The Preakness Stakes and the Belmont Stakes. Only 11 horses have ever won all three.
The Preakness Stakes is run over a 9.5 furlong course.
the Belmont Stakes is run 3 weeks after the Preakness Stakes (or 5 weeks after the Kentucky Derby).
It is run at Pimlico Racetrack in Maryland.
During any given year there are thousands of horse races run in the US. Therefore, it would be better to ask which horse races are part of the Triple Crown. Those races are the Kentucky Derby, the Preakness Stakes, and the Belmont Stakes.
Because the Kentucky Derby is for horses classified as three years old. This means they can only run once, when they are three years old.
The selection of horses to run in the Triple Crown begins with horses meeting what are called "race conditions" for the Kentucky Derby; conditions stipulate the age, gender and past performance requirements each horse must meet to enter a given race. The Kentucky Derby is written for 2 year-olds, fillies and colts, [here it says something like "...non-winners of x number of races..." and/or "winners of x number..."] The winner of the Kentucky Derby gets to run in the Preakness, and the winner of the Preakness gets to run in the Belmont. So the "selection process" begins with being eligible to run the Derby.
The Preakness is the second leg in Americanthoroughbred racing's Triple Crown and almost always attracts the Kentucky Derby winner, some of the other horses that ran in the Derby, and often a few horses that did not start in the Derby. Two years before the Kentucky Derby was run for the first time, Pimlico introduced its new stakes race for three-year-olds, the Preakness, during its first-ever spring race meet in 1873 . Joan Cowin.
The Kentucky Derby is run at 1 1/4 miles and is the 2nd longest of the Triple Crown races. The Preakness is the shortest and is run at 1 3/16 miles.
The Preakness Stakes is run on dirt at Pimlico Race Course in Baltimore, Maryland. It usually takes place on the third Saturday in May and is the second leg of the U.S. Triple Crown, following the Kentucky Derby. The race covers a distance of 1 3/16 miles.
The only age at which any hosrse can run in th KY Derby is 3 (three) yrs old, as is the case with the other two Triple Crown races--the Preakness Stakes and the Belmont Stakes.
Absolutely NOT! A filly is a young female horse...A colt is a young male horse!!! They usually race 2-3 yr. olds in the triple crown, which if I'm not mistaken, is maturity age for horses. I could be wrong, but I don't think so!The age for horses to race in the 3 Triple Crown races--the KY Derby, the Preakness Stakes, and the Belmont Stakes--is specifically 3 yrs. of age. Fillies are most welcome to run in any of the races and a very limited number have won. In order they are:Regret won the KY DerbyGenuine Risk won the KY DerbyWinning Colors won the KY Derby (1988)Rachel Alexandra won the Preakness (2009)Rags to Riches won the Belmont (2007)There is, however, an "unofficial" TC for fillies, known as the "Triple Tiara" that consists of: the Acorn Stakes run at Belmont and the Coaching Club American Oaks and the Alabama Stakes, both run at Saratoga Race Course in Saratoga Springs, NY.
