Update

Now that I've gone over the basics, I just wanted to let you know of some sites where you can find a bunch of information that your looking for. I'm not sure how much experience you've had, if you've been in aqha for a while you probably know all the stuff I'm going to tell you. I am not endorsed by aqha by any means.
But Aqha has a really good series called showing to win.

• they have showmanship
• horsemanship
• trail
• pleasure

if your looking for something involving reining or ranch horse. the NRHA puts out a good series on how to complete their patterns to the best of your abilities. For English I would look up some videos on you tube and I'm sure there is tutorials available.
But here are some good websites.

• You Tube, Search for world show winning runs so you can watch how they do it.
• Equine chronicle online has some really good articles that they have published in the magazine, and our offering, they are free.
•  Go Horse show.com is probably the best. If your looking for any kind of advice tips or news about shows they have it. They have done some really good articles with Bruce Vickery, and charlie Cole about what it takes to win.
• In the Show horse today Magazine, Mark Sheridan also did a really good 7 part horsemanship article. 

 There is a lot out there to be offered, and if you want to practice judging or something aqha has free printable scoresheets for all the classes that need them.
