There are a variety of different jumps you can use to build a course. The choices you make are somewhat influenced by the style of riding that you do. Jumpers typically jump over brightly colored fences, while hunters favor a more natural looking course. Whether you are building a course for hunters or jumpers, you probably want to add some variety.
The majority of your course is probably made up of standards or wings, and poles. You can build verticals and oxers with these jump components. Using these types of fences as the backbone of your course allows you to get creative with a few other fences.
Horse jump walls are a fun addition to both a hunter or jumper course. If you show jumpers, you can add some brightly colored poles to the top of the wall to make it taller and to coordinate better with your other jumps. If you are building a course for hunters, the wall on its own is fine, although many people like to add a natural colored pole to the top. Adding some greenery, either by adding some potted shrubs in front of each standard, or using a flowerbox as a ground line, can really dress up this type of fence.
Horse jump walls are a great addition to a practice course as well as a show course. Although they may seem intimidating to the inexperienced rider, their solid appearance typically creates confidence in the horse. Using a wall as part of a combination or along a long diagonal line can encourage your horse to move boldly toward the fence.
Schooling and showing over a variety of fences, including walls, helps build confidence and skill in both the horse and rider. While it is impossible to prepare for every type of fence available while schooling if you and your horse are accustomed to tackling new fences on a regular basis, you will have the confidence to do so when it matters. Variety is important when developing your jumping skills.
