We've talked a lot about Keeneland here on HerKentucky lately. We've shared our ideas on what you should wear and what you definitely shouldn't wear. We've told you how to place a wager like a pro (or at least an informed amateur). You should be all set for a trip to the track, right?

Now, if you find yourself at the race track tomorrow, you can anticipate a huge crowd, even by "Saturdays at Keeneland" standards. The eighty-ninth running of the Toyota Blue Grass Stakes will commence tomorrow afternoon at 5:40 p.m. The Blue Grass Stakes (G1), is perhaps the most important race of Keeneland's racing year, generating at least one Derby contender. That's a lot of information to take in, but it's pretty easy to talk about Big Races like a pro. Here's what you need to know:

Graded Races

Obviously, the really fast horses run in the big money, high stakes races. These races are graded by purse amounts. (A "purse" is the total amount of money paid out to the owners of the winning horses. Usually, horses placing first through fifth are eligible for a portion of the purse.)
Any race considered for grading must have a total purse value of at least $75,000. The Grades are "Listed" -- at least $75K; "Grade III" -- at least $100K; "Grade II" -- at least $150K; and "Grade I" -- at least $200K.
The Blue Grass Stakes is a Grade I Race with a $750,000 purse.

Derby Prep

Purse earnings formerly determined horses' eligibility for the Kentucky Derby. As of this racing season, horses qualify for Derby through a points system. You can find the entire list of Derby qualifying races here.
The winner of the Blue Grass Stakes is awarded 100 points and is guaranteed a slot in the Kentucky Derby. This is the highest point-value race run in Kentucky.
