Cross country equestrian jumping forms one of the three phases of the sport of eventing; it may also be a competition in its own right, known as hunter trials or simply "cross-country", although these tend to be lower-level, local competitions.

The object of cross-country is to prove the speed, endurance and jumping ability of the true cross-country horse when he is well trained and brought to the peak of condition. At the same time, it demonstrates the rider's knowledge of pace and the use of this horse across country. (While cross-country tests a horse's endurance over a short period, endurance itself is a separate sport, involving long-distance cross-country riding without jumps).

Course

Length and types of obstacles

The cross-country course is approximately long, comprising some twenty-four to thirty-six fixed and solid obstacles. Obstacles usually are built to look "natural" (out of logs, for instance), however odd materials and decorations may be added to test the horse's bravery. Obstacles can include all those that might be found if riding across the countryside, including water, trees, logs, banks, and ditches.

All obstacles or compulsory passageways are flagged, with a red flag on the right and a white flag on the left. A black stripe on the red flag indicates that it is an option for the obstacle, and another route may be taken if the rider so chooses, without penalty. All obstacles are numbered, and the color of the numbering can indicate which level the fence is for if multiple levels are competing at the event. (for example, white numbers on a green background indicate that the fence is on the Preliminary level course, however, in British eventing, this color combination would indicate the intermediate track, so riders should always check the course map for course markers).

Design

Cross-country courses for eventing are held outdoors through fields and wooded areas. The terrain is unique for each course, which usually incorporates the course into the natural terrain of the area, and therefore events in certain parts of the world may be held on mostly flat land, while others are over very strenuous hills.

Course designers may use the terrain to either help an inexperienced horse and rider prepare for an obstacle, or to make an obstacle more difficult for the experienced competitors. For example, the designer may place a fence at the opening of a wooded area, resulting in a lighting difference between the takeoff and landing side. This requires careful riding and a confident horse. Designers may make an obstacle more difficult by placing it along the side of a steep hill, at the top of a mound (so the horse can not see the landing until he is about to take off, testing bravery), or use the natural trees and ditches to force riders to take slightly more difficult lines to their fences.

It is desirable for obstacles to be incorporated into the landscape so that they seem natural, while still fairly testing the horse. Horses should also be provided an option to run-out if the rider makes a mistake. Most designers use accuracy fences, such as skinnies (fences with a narrow face) and corners, to make the rider's job more difficult while still being very "horse-friendly."

All courses begin with a "start box", where the horse and rider wait as the time keeper begins to count-down to their start time. They are not allowed to go out the front of the box before the timer reaches zero on the count-down, nor are they allowed to have a flying start. The first few fences of most well-designed courses are usually straightforward and inviting, such as a large log or roll-top, which helps to build the horse and rider's confidence, get them settled in a galloping rhythm, and beginning to focus on the job at hand. The technicality of the obstacles then begins to increase, and elements such as banks, ditches, and water are introduced. The final fences of a course are usually slightly easier to allow the horse and rider to finish on a good note before they gallop across the finish.

Footing Good footing is very important to most riders, as it helps decrease the wear-and-tear the sport has on their horses and avoid injury that may occur due to deep or slippery ground. The rider should always take care to note the footing while walking the course, and adjust the planned route to avoid patches that are especially boggy, slippery, or rough, and to avoid holes that may be present.

Footing is never used to make a course more difficult (for example, a fence is never purposely placed in a boggy area or one with sharp rocks). Instead, most competitions go out of their way to keep the footing safe, and many of the larger events may "groom" the footing to get it to the appropriate firmness.

Walking Riders walk a cross-country course, usually between 1–3 times, before they actually ride it. This allows them to evaluate the course and determine how each jump needs to be ridden. While walking the course, riders need to be sure to pay attention to:

Because the horse's eyes do not adjust quickly to light, great care must be taken on the approach to fences that are set near the boundary of a drastic change in light.TerrainFences ridden up or downhill require a particular type of ride, as do fences with a drop on landing.Linethe particular route a rider is going to take over an obstacle.

Striding will vary according to the height and width of the obstacle, whether it is in water, on a hill, or going up or down a bank.Opennessareas that are more open, such as a field, generally encourage forwardness from the horse. Galloping tracks through the woods, especially if they are windy, lose forwardness from the horse.Course layoutcourses that are "gallopy" with plenty of room between fences can help encourage a horse that is less brave, as the rider has plenty of room to get him forward and into a rhythm. They also give the rider a chance to make up time. Fences that are jumped towards other horses (such as toward warmup or stabling) generally make a horse more confident and eager. Additionally, the layout of the various "questions" a course designer asks can help build a horse's confidence: for example, a combination into water at the beginning of a course will help set up the horse for success for a more difficult drop fence into water later on in the course."Bogey" fencesobstacles that may be of concern to a particular horse or rider (for examples, some horses are less brave when jumping into water or over a ditch). These need to be ridden with extra confidence from the rider, and the rider must keep contact with the horse at all times.Distractorsthis includes livestock that are pastured near the course (such as cows and sheep), decorations on the fences which may scare certain horses, flags, etc. At the larger venues, such as the CCI**** events, crowds can be very distracting to some horses.

Conditioning

Conditioning is an essential part of preparing a horse for cross-country. Although the lowest levels may not require anymore riding than the usual 5 or 6 days each week used to train the horse, all upper level horses are placed into strict conditioning programs. Most riders plan their schedule around per-determined events, taking into consideration the length of the particular course, the climate in which they will have to run their horse, the speed that will be required, and the terrain over which they will be traveling (such as hills). In extreme situations, such as when riders had to condition their mounts for the intense heat at the Athens Olympics, horses will be shipped in early to certain locations to help their body adjust.

The rider must also consider the starting condition of the horse, the breed which they will be competing (heavier breeds will require more conditioning than most Thoroughbreds), and most importantly, the individual horse. Horses which have been brought to peak fitness before will generally be easier to get back to top condition than a horse that has never had to work at that level. Some horses need more distance work and others more speed work. Determining these factors is generally done through experience.

Training for cross-country All horses are started with distance work, at a slow speed (usually a walk or trot), to improve endurance. This "base" of fitness is vital to ensure the horse is physically sound enough to progress to more rigorous work, such as galloping. Horses who do not have a base are much more at risk for soft tissue injury. After a base has been placed on the horse, riders add in galloping sets to improve cardiovascular fitness. Most riders use interval training, in which the heart rate is raised to a certain level before the horse is allowed a rest, and then the horse is again asked to work before the heart has a chance to fully recover. This can improve the cardiovascular fitness of the horse with less overall galloping, helping to maintain the horse's soundness.

Work up an incline (hill work) is often favored over longer stretches of galloping for improving fitness, because it requires the horse to work harder while placing less wear-and-tear on their body. Through experience, a rider may gauge the difficulty of a hill and determine what its comparative worth is to galloping on a flat surface.

To condition the horse's bones, riders may walk on roads or other hard surfaces. However, this is generally only used when the ground conditions are quite soft. Although popular in Britain, most American riders do not do road work. If used too much, it can encourage arthritis.

Some riders also have access to equine treadmills or swimming pools. Treadmills can sometimes be adjusted to have a slight incline, allowing the horse to work without the added weight of the rider. Swimming is an excellent form of conditioning, and allows the rider to increase the horse's cardiovascular and muscular condition without adding undue stress to the bones or soft tissue.

Considerations Riders should always be wary of the ground conditions. Conditioning on hard ground can cause lameness problems, both short and long-term. Conditioning on deep, heavy footing (such as right after a rain) increases the pull on the tendons, and may lead to soft tissue damage. Conditioning on slippery ground increases the risk that the horse will slip and have a soft-tissue injury. In general, older horses do better on softer footing, which is kinder to any joint problems they may have. Younger horses, which may not have the same strength of soft tissue, are best worked on slightly firmer ground.
