Stables
The Stable is where you manage your racehorse.  Here, you may purchase or sell your racehorse.  Once you own a racehorse, you can begin training it, which increases your horse's development and increases its chances of performing well in races.

Purchasing
To purchase a racehorse, scroll through the available horses.  Its age,w sex (colt or filly), number of starts/wins, total earnings, running style and purchase price are provided.  But just like real horses, other qualities are hidden - you'll find out how good your horse is when you start training it and eventually hit the racetrack.
Once you've found a horse within your budget, click on "Purchase." You are now a horse owner!  You may name your horse anything you'd like (no profanity, please!).

Status
Once you own a horse, it's "Status" page appears.  The Status Page displays your horse's vital statistics as well as his progression in four characteristics: Dirt Speed, Turf Speed, Stamina and Guts.  By training your horse, you can improve your horse in these characteristics, which will increase your horse's chances for success at the races.

Training
Click on "Train" your horse to see the available training exercises.  Each exercise will increase a different characteristic.  Some are obvious - for example, a Dirt workout would increase your horse's Dirt Speed.  But some exercises are random; you don't know exactly what it will do for your horse.  By experimenting with different training techniques, you can figure out what is the best course of action for your horse.  Each training exercise will advance your horse's age by one week.

Selling
If your horse just is not performing or you are in need of cash, you may sell your horse at anytime.  Generally, you may sell you horse for 25 percent less than what you purchased it for.
When you're happy with your horse, it's time to go to go to the races!
