The Basics Of The Kentucky Derby for Horse Racing Beginners

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.

Despite the complexity of understanding horse racing, there are a few basic rules that can help the novice watch the Kentucky Derby with a greater degree of enjoyment. Until recently, the Derby was a race dominated by the favorite. In the 1970’s great horses like Secretariat and Seattle Slew blew away the field but since Spectacular Bid’s winning run in 1979 there have been only a couple of favorites to win the big race. While a serious horse player might not want to categorically dismiss the popular favorite, for the horse racing novice this is a helpful way to narrow down the field.

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 couple more factors to consider are the horse’s gender and breeding lineage. A couple of simple rules can be applied here–first of all, forget all horses that aren’t intact males (geldings and fillies). Over 90% of all Derby winners have been intact males. Then, eliminate any horse that wasn’t born in the state of Kentucky. This stipulation is starting to change, but for the time being is a good rule to apply for the novice. Over 80% of all Derby winners have been born in Kentucky.

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.
