Dressage by Sandra Auffarth.
A rider competing in Dressage wears decorative clothing, including a top hat, tailcoat, and spurs. Although a whip is used in training, it is disallowed in the arena, and is used to aid humane communication rather than physical dominance over the horse
The arena is set up with alphabetical markers to help guide you through your routine. The size of the arena is either 65 x 22 yards for higher level participants, or 44 x 22 yards for the lower end. The arena surface is different from that of the other areas of the stadium to create an barrier between the arena and the viewing area. If the horse leaves the arena surface, the rider is disqualified. The key to the surface is that it acts like turf, with the best surface said to be a combination of rubber and sand pieces
The keys to competing in Dressage according to The Complete Horse Riding Manual are purity, acceptance, calmness and forwardness.
Show Jumping by Nick Skelton
The equipment for this type of event is comfortable because must be able to move freely without constriction or difficulty. According to Micklem a rider must wear a jacket, shirt, tie, breeches, boots, gloves, and a hat. And the horse must have a specialized saddle, bridle, and protective boots. The special saddle is flat so the rider can stay close to the horse over the fence and on the decent as well.
To train for show-jumping, a rider must move through different levels of exercises and fences to progress. It is also important to learn how to judge the stride length of the horse so you can move through the course smoothly without mistakes. To begin in the sport, practice involves learning the basics of dressage, and simple jumping.
Courses in show-jumping start at the novice level with fences set at 3 feet 6 inches in height and only a few variations in the jumping variables. The next level is elementary courses with fences at the height of 3 feet 9 inches, and a max jumping length of 4 feet 6 inches. There is a triple jump usually involved; the course must be completed in a time of 90 seconds. The third level is the medium course with 4 feet 3 inch heights and 4 feet 9 inch spreads in jumps and a 90 second finishing time. The last level for the event is the advanced course, with 4 feet 6 inch heights and 5 feet 2 inch spreads. It has to be completed in 72 seconds and involves a water jump and awkward distances between obstacles that can be tough to judge.
