The Basics Of The Kentucky Derby for Horse Racing Beginners

By Ross Everett

Although the Breeders' Cup is nipping at its heels, without a doubt the Kentucky Derby is the biggest horse race of the year in the United States. This is a race that attracts many fans from the general public that typically don't follow horse racing. A thorough understanding of horse racing, and which horses will win and why is a complex discipline that requires extensive specialized knowledge.

A true fluency in horse racing takes extensive study, but here are a few concepts that can help anyone better understand and enjoy the Kentucky Derby. Until recently, the Derby was a race dominated by the favorite. Since Spectacular Bid won the Derby in 1979, however, you can count the favorites who've won the race on one hand with fingers left over. In other words, the easiest way to pare down the field for a horse racing novice is to simply eliminate the popular favorite from consideration.

In all fairness, it should be noted that the favorite has been a historically strong proposition. In the 135 Kentucky Derby races the post time favorite has placed in the money at a 69% clip over the history of the race. So why have the favorites been on such a money losing run in the past two decades? My personal theory is that it is a function of the growing hype surrounding the race"in other words, you get a lot of amateur horse racing fans that distort the notion of the favorite being the most likely to win the race. The most hyped horse becomes the favorite, but this is not always the best horse. In any case, though it could be argued that the anti-favorite bias could be due for a turnaround, for the purpose of understanding this particular race Im going to forget about the post time favorite.

Another important component of Kentucky derby success is the post position of the horses. The innermost positions (1 through 5) have produced over 40% of all Derby winners, while the outer post positions (11 through 20) have had only 13% winners. Note that in some years there might not be that many horses in the race, which would help partially explain the poor performance of the outer start positions. Still, for the purposes of understanding a single race eliminating all of the less favorable start positions is a good idea.

A horse's lineage and breeding is also an important factor in the race. While this may be the most complex and demanding area of horse racing, there is a simple rule of thumb that can help a novice for this race. Most high level race horses are born in Kentucky. Well over 80% of Derby winners have also been born in the Bluegrass State. So just eliminate all horses that weren't born in Kentucky. Then consider a horse's gender and eliminate any horse that isn't an intact male (geldings and fillies). Over 90% of all Derby winners have been intact males, though a gelding did win the race in 2003 (Funny Cide). For the horse racing novice, however,this is another good way to pare down the field.

Also, take a look at dosage index numbers. For the novice, there's no real reason to worry about what they mean or how they're figured but the general rule of thumb is to look for a horse with a dosage index of 4.00 or less. Since 1984, over half of all Derby winners have fit this criteria.

For a more serious introduction to horse racing, check out the many books available on the subject at any large bookstore. For a casual fan who just follows the 'big races' these rules will help you get a decent grasp on the Kentucky Derby and understand who will win and why.
