English
Extended trot is one of the most expressive and demanding movements in dressage, showing the horse’s ability to lengthen the stride and frame while staying rhythmic, balanced, and in self-carriage.
When ridden well, the horse appears to float forward with long, ground-covering steps and an unhurried moment of suspension. The movement may look effortless, but correct extension depends on strength, suppleness, impulsion, and clear communication between horse and rider.
Extended trot first appears in competition at USDF Third Level and continues through the FEI levels, where it becomes an increasingly important test of collection, throughness, and training quality. Asking for extension before the horse is physically and mentally prepared can lead to rushing, hollowing, or loss of balance.
Keep reading to learn what extended trot is, what horse and rider need before developing it, how to apply the aids, and which exercises can help build the movement correctly over time.
What Is Extended Trot in Dressage?
Extended trot is a variation of the trot gait in which the horse lengthens both stride and frame to the fullest extent its training and conformation allow, while maintaining rhythm, balance, and self-carriage.
The energy needed for a successful extended trot originates in the hindquarters. The hind legs push with increased thrust, the back swings freely, and the forehand reaches forward to match. The horse covers the maximum amount of ground it can in each stride without rushing or losing balance.
Extended Trot vs. Medium Trot vs. Working Trot
Extended trot is not just a faster trot, and it is not the same movement as medium trot.
Working trot is the baseline. Active and balanced, with the horse tracking up and working freely through the back, it is the most natural and efficient way of going for most horses.
Medium trot shows a moderate lengthening of stride and frame. The steps are clearly longer than in working trot, and the horse should show an increased moment of suspension. It is a distinct movement, not a weaker version of extension.
Extended trot asks for the maximum. The horse’s neck reaches forward and out, the frame lengthens, and each stride covers as much ground as possible.
Research comparing stride kinematics across all four trot variations in highly trained dressage horses found that well-schooled horses achieve extension by increasing stride length rather than quickening tempo, meaning the rhythm stays consistent even as each step grows larger. [1]
Getting the horse to lengthen without quickening is one of the central challenges of training the movement.

What Judges Look for in Extended Trot
Judges evaluate extended trot on several criteria, including: [2]
- Regularity and elasticity of the steps
- The degree of frame lengthening
- Impulsion from the hindquarters
- Uphill tendency
- The horse’s ability to maintain balance
The quality of the transitions into and out of the movement is also factored into the score. [2]
According to FEI judging guidelines, trot quality is assessed by the general impression of regularity and elasticity, originating from a supple back and well-engaged hindquarters, and by the horse’s ability to maintain the same rhythm and natural balance across all trot variations. [2]
In extended trot specifically, the horse should show a visibly longer stride than in working or medium trot, a forward-reaching neck and nose, a clear moment of suspension, and smooth, prompt transitions at both ends.
An extended trot is always shown on a straight line in standard dressage tests. In competition, this is typically the long diagonal.

Prerequisites for Riding Extended Trot
Many riders introduce extension before the foundation is ready. When that happens, the horse compensates by running, hollowing, or losing rhythm.
The three prerequisites below are the foundation that makes the movement possible.
1) Collection & Carrying Power
The relationship between collection and extension is not obvious at first. Collection comes before extension and is essential for performing extended trot correctly.
The horse must learn to compress and carry weight on the hindquarters before it can release that stored energy into a long, expressive stride. Research examining the biomechanics of dressage gaits has described collected trot as a running gait in which the hind limbs act as springs, storing and releasing elastic energy with each stride. [3]
This helps explain why correct extension depends on carrying power, not speed. A horse that cannot collect will often run when asked to extend. One that has learned to carry weight on the hind legs can release that energy forward without the rhythm breaking or the balance tipping onto the forehand.
Collection is the mechanism by which the rider builds the energy that becomes extension.
2) Impulsion & Throughness
Impulsion is controlled, elastic energy that travels from the hindquarters forward through the horse’s body. It is not speed, nor is it activity in the legs alone. A horse can trot with great energy and a tight back and still lack true impulsion.
True impulsion requires a swinging, relaxed back. The energy generated behind must pass through the horse’s topline and arrive at the contact. When that channel is open, the horse can extend with real power and expression. When it is blocked by tension or bracing, the extension has nowhere to go.
If the horse tightens the back or resists the hand when asked to extend, the problem is often throughness. Returning to suppleness work, forward-thinking transitions, and relaxation exercises will usually produce more improvement than continued drilling on the diagonal.
3) Physical Readiness & Conditioning
Extended trot places considerable physical demand on the horse. It requires strength through the hindquarters and lumbar region, a well-conditioned topline, cardiovascular fitness, and elasticity through the soft tissues of the limbs.
Kinematic research comparing medium and extended trot to collected trot found that fetlock extension in both the fore and hind limbs increases significantly as horses move into lengthened paces. [4] This suggests that the joints and soft tissues of the lower leg work harder as the horse increases stride length and ground cover.
Equine biomechanics specialists note that extended trot cannot be safely performed until the horse’s musculoskeletal system is mature and conditioned, as it requires muscular strength, power, and elasticity. [5] A horse without the physical preparation to support that load may compensate by rushing, hollowing, losing balance, or placing excess strain on the limbs.
Introducing extended trot too early does not speed up development. It can build compensation patterns that become ingrained and, over time, may contribute to injury.
Rider Position in Extended Trot
Few things affect a horse’s ability to extend more directly than the rider’s position. Riders who push strongly, drive with the seat, or grip with the legs in an attempt to create more movement can block the horse’s back and restrict the freedom that extension requires.
The Seat & Core
The rider’s pelvis needs to follow the horse’s movement softly and without tension.
In sitting trot, the pelvis rocks gently forward and back with each stride. Gripping, bracing the lower back, or pushing with the seat suppresses the natural swing of the horse’s back and prevents the throughness that extension requires.
Research quantifying how rider weight affects thoracolumbosacral kinematics in high-level dressage horses found that being ridden in sitting trot measurably altered back rotation patterns compared to the same horses trotting in hand. [6] Motion analysis confirms that a tense or blocking seat changes what the horse can do.
Core stability, not core tension, is what the rider needs. The aim is to stay centered and balanced while remaining soft enough to follow the horse.
Riders who cannot yet sit extended trot without bouncing or bracing may find that rising trot allows the horse’s back to swing more freely. A well-timed rising trot can produce better quality movement than a seat that interferes.
Hands, Frame & Following Contact
The hands must allow the horse’s neck and frame to lengthen as the stride grows. Extended trot requires riders to maintain a consistent, elastic feel while easing the hands slightly forward to give the horse room to reach through the neck and shoulder.
A fixed or resistant hand causes the horse to come short in the neck, potentially drop behind the vertical, and lose freedom through the shoulder. The hand follows the energy forward.
Research using inertial sensors to compare biomechanical data with judge scores in dressage horses performing extended trot transitions found that kinematic variables in the horse’s trunk and limbs correlated meaningfully with the marks awarded. [7]
What is happening in the horse’s body and what the judge sees are directly connected. A rider who holds with the hands compromises both.
How to Ask for Extended Trot
The aids for extended trot are less forceful than many riders expect. Preparation carries most of the work. When the horse is properly organized and engaged, asking for extension feels more like a release than a demand.
Preparing with Half-Halts
Use the corner before the diagonal to prepare the horse. Ride a series of half-halts to organize the balance, engage the hindquarters, and compress the energy. The horse should feel loaded and attentive coming out of the corner, not slow.
The quality of the preparation determines the quality of the extension. Riders who skip this step and turn onto the diagonal expecting more usually get rushing or scrambling instead. Think of the corner as the moment of loading. The diagonal is the release.
The Aids for Extension
As you straighten onto the diagonal, allow your weight to settle softly into the saddle. Close both legs at the girth to send energy forward. At the same moment, ease the hands fractionally forward to invite the horse to lengthen the neck and reach into each stride.
Avoid kicking or pushing aggressively. If the horse is properly prepared and in front of the leg, a clear but quiet aid is all that is needed. A strong driving aid typically creates tension and rushing rather than expression and swing.
Watch that the tempo does not increase as you ride down the diagonal. The stride should grow longer. If the rhythm quickens, the horse is running rather than extending, and the preparation was insufficient.
The downward transition requires equally deliberate preparation with half-halts. Come back gradually and smoothly. FEI judging guidelines are explicit that the transitions into and out of extended trot form part of the movement and are reflected in the score, making the end of the diagonal as important as the beginning. [2]
Exercises to Develop Extended Trot
Extended trot improves through systematic work across the training session, not through repeated drilling of the movement. The exercises below build the strength, responsiveness, and elasticity that enable extension.
Transitions Within the Trot
Frequent transitions between working, medium, and collected trot are among the most effective tools for developing extension. These transitions activate the hindquarters, sharpen the horse’s response to the aids, and teach the horse to shift between degrees of engagement without losing rhythm or balance.
One exercise favored by Grand Prix trainers begins in working trot on the long side of the arena. Walk at the letter before the corner, ride a half walk pirouette to bring the horse back to the same wall facing the opposite direction, then use the lightest possible aid to transition back to working trot. [8]
The pirouette activates the inside hind leg, and the immediate forward transition encourages the horse to think ahead of the rider rather than settling into a passive rhythm.
Short trot-to-walk and walk-to-trot transitions throughout the session build the same reactive quality over time. Lightness of response matters far more than explosive energy.
Lateral Exercises as Preparation
Shoulder-in and leg-yield are the most consistently useful lateral exercises to ride before asking for extension. Both encourage the horse to step under with the inside hind leg, build suppleness through the back, and prevent forward rushing by keeping the horse actively engaged.
A sequence many professional trainers use is shoulder-in down both long sides before turning directly onto the diagonal for medium or extended trot. [5] In this exercise, the horse arrives on the diagonal already organized and carrying, and the transition into extension comes naturally because the energy and engagement are already there.
Leg-yield from the quarter line back to the wall serves a slightly different purpose. It activates the pushing power of the hind legs without the same degree of lateral bend as shoulder-in, and it creates forward energy that can be directed into lengthening.
Combining both exercises in the same session gives the horse variety and prepares both the carrying and thrusting functions of the hindquarters.
Uphill Work & Gradual Lengthening
For horses that rush or lose balance when extension is first introduced, gentle uphill terrain is a practical teaching tool. A gradual incline naturally encourages the horse to push from behind rather than fall onto the forehand, because the horse shifts weight back to manage the climb.
Begin by asking for just two or three steps of honest lengthening before returning to a more collected pace.
Quality matters far more than quantity at this stage. Two clean, rhythmic, ground-covering strides are worth more than a full diagonal of rushed, unbalanced movement. Build gradually over weeks and months, always prioritizing rhythm and balance over scope.
Horses that run when extension is introduced on flat ground often find the concept much clearer on a hill, then carry that understanding back into arena work once the pattern is established.
Common Faults in Extended Trot & How to Fix Them
Most problems in extended trot are symptoms of something missing lower on the dressage training scale. Identifying the root cause is more productive than drilling the movement. In most cases, the fix is found by going back, not by pushing forward.
Running & Loss of Rhythm
Running is the most common fault. The horse quickens the tempo instead of lengthening the stride, falls onto the forehand, and the hind legs trail rather than push.
The cause is almost always insufficient collection and engagement before the ask. The horse has no stored energy to release into extension, so it fills the gap with speed.
The fix is not to keep asking for extension while also trying to slow the horse down. Return to collected work, use more deliberate half-halts before any lengthening is attempted, and use circle work or uphill terrain to help the horse find balance.
Build from just a few well-balanced strides. The horse that offers three good strides and is rewarded for them will develop extension.
Hollowing Through the Back
When a horse raises the head, tightens through the back, and loses throughness as extension is asked, the rider’s seat is usually the first place to look. A driving seat or tension in the rider’s lower back compresses the horse’s topline.
Soften the seat, follow the movement rather than creating it, and observe whether the horse’s back frees up. If hollowing persists after the rider relaxes the position, return to suppleness work at slower gaits before attempting extension again.
Horses that consistently hollow under forward pressure need more time in relaxation and suppleness work before the demands of extended trot are added.
Lack of Foreleg Expression or Short Reach
Some horses show adequate hind leg activity but do not match it with foreleg reach, resulting in an extension that feels uneven or appears short in front.
This is often a suppleness issue rather than a conformation limitation. The horse may be tight through the shoulder or not adequately warmed up, and the forelimb cannot match the swing that the hindquarter push demands.
Cavaletti work at trot helps improve shoulder freedom and foreleg lift without the rider needing to manufacture it through the aids. A thorough warm-up that includes stretching and lateral exercises before any extension is requested also makes a meaningful difference.
Horses that are consistently short in front tend to respond well to pole work and to more time in a stretching frame before demanding work begins.

Finding Extension in the Ring
Extended trot is one of the clearest tests of whether a horse can turn strength, balance, and relaxation into expressive movement. The goal is not to create more speed, but to develop a longer, more powerful stride while preserving the same rhythm, contact, and self-carriage that are present in correct work at every level.
For most horses, the quality of the extended trot depends on what happens before the diagonal. Collection, impulsion, throughness, physical conditioning, and rider position all determine whether the horse can lengthen honestly or has to compensate by running, hollowing, or falling onto the forehand. A quiet, well-timed aid can only work when the horse is already prepared to answer it.
Good training builds extension gradually. Asking for a few balanced, ground-covering strides is often more productive than repeating full diagonals before the horse has the strength to maintain quality.
The rider’s responsibility is to organize the energy, then allow it to continue forward. When problems appear, the best answer is usually to return to the foundation: rhythm, relaxation, suppleness, connection, impulsion, and collection.
A correct extended trot should feel powerful but unhurried. With patient preparation and careful attention to the horse’s physical readiness, riders can develop an extension that is not only more expressive in the arena, but also healthier, more balanced, and more sustainable over time.
Frequently Asked Questions
Here are some frequently asked questions about riding an extended trot:
Extended trot in dressage is a trot variation where the horse lengthens both the stride and frame to the fullest extent its training and conformation allow. The horse should cover more ground without rushing, losing rhythm, or falling onto the forehand. Correct extension comes from increased thrust behind, a swinging back, and an elastic contact that allows the neck to reach forward.
Extended trot first appears at USDF Third Level in the United States. Medium trot appears earlier at First Level, but it asks for a more moderate lengthening of stride and frame. Extended trot becomes more demanding at higher levels because it tests collection, impulsion, throughness, balance, and the quality of the transitions.
The difference between medium trot and extended trot is the degree of lengthening. Medium trot shows a clear but moderate increase in stride length and frame, while extended trot asks for the maximum lengthening the horse can produce while staying balanced. In both movements, the horse should lengthen the stride rather than simply quicken the tempo.
A correct extended trot should look powerful, balanced, elastic, and unhurried. The horse's neck reaches forward and out, the frame lengthens, and each stride covers more ground while the rhythm stays steady. The hindquarters should generate the energy, the back should swing freely, and the transitions into and out of the movement should be smooth and prompt.
A horse does need collection before learning extended trot correctly. Collection teaches the horse to carry more weight behind and store energy in the hindquarters before releasing it into a longer stride. Without this foundation, the horse is more likely to run, hollow, or lose balance when asked to extend.
A horse that runs instead of extending the trot is usually quickening the tempo because it lacks sufficient collection and balance before the ask. Without organized energy in the hindquarters, the horse responds by going faster rather than lengthening the stride. The best fix is to return to collected work, improve the half-halts, and build from a few balanced lengthening steps instead of pushing for a full diagonal.
To ask a horse for extended trot, prepare in the corner with half-halts that organize the balance and engage the hindquarters. As you straighten onto the diagonal, close both legs at the girth, keep your weight settled and soft, and allow the hands slightly forward so the horse can lengthen the neck and frame. The aid should feel clear but quiet, because aggressive kicking or driving often creates rushing and tension.
Your hands in extended trot should maintain elastic, consistent contact while allowing the horse to reach forward. As the stride lengthens, the neck and frame need room to lengthen too, so the hands should follow the movement rather than hold it back. A fixed or resistant hand can shorten the neck, restrict the shoulder, and reduce the quality of the extension.
Extended trot is generally ridden in sitting trot in dressage tests unless the rules for the level or test state otherwise. In training, rising trot can be useful if the rider cannot sit the movement without bouncing, gripping, or blocking the horse's back. A soft, well-timed rising trot may allow better swing and throughness than a tense sitting trot.
Exercises that help develop extended trot include transitions within the trot, shoulder-in, leg-yield, uphill lengthenings, and short, balanced trot-to-walk transitions. These exercises improve engagement, suppleness, responsiveness, and the horse's ability to push from behind without rushing. The goal is to build the ingredients for extension throughout the session rather than repeatedly drilling the diagonal.
A horse that hollows when asked for extended trot is often reacting to a blocking rider position or a lack of throughness through the back. A driving seat, braced lower back, or fixed hand can prevent the horse's topline from swinging freely. If softening the rider's position does not help, the horse likely needs more relaxation, suppleness, and forward-thinking transitions before extension is added again.
When training extended trot, start with only a few high-quality lengthening strides. Two or three balanced, rhythmic, ground-covering steps are more valuable than a full diagonal of rushing or loss of balance. Over time, those short efforts can be developed into a longer, more reliable extension as the horse gains strength and understanding.
Most horses can learn to produce an honest extended trot when the training foundation is correct. Natural talent, conformation, breeding, and movement quality influence how expressive or ground-covering the final result becomes. The goal is not to force every horse into the same picture, but to develop the maximum correct lengthening that horse can offer while maintaining rhythm, balance, and self-carriage.
Physical conditioning is important for extended trot because the movement places greater demand on the hindquarters, topline, cardiovascular system, joints, and soft tissues of the limbs. The horse must be strong enough to push, carry, swing through the back, and absorb the increased forces of lengthened strides. Introducing extension before the horse is mature and conditioned can encourage compensation patterns and may increase soundness risk over time.
Judges look for regularity, elasticity, impulsion, frame lengthening, uphill tendency, balance, and clear difference from working or medium trot. The horse should maintain rhythm while showing longer, more ground-covering strides and a forward-reaching neck. The transitions into and out of extended trot also matter, so the movement is judged as more than just the biggest steps on the diagonal.
A lack of foreleg reach in extended trot is often related to suppleness, shoulder freedom, or insufficient warm-up. Cavaletti, pole work, stretching, and lateral exercises can help the horse develop better swing and freedom through the shoulder without the rider trying to manufacture bigger movement. If the hindquarters are pushing but the front end stays short, focus on throughness and mobility before asking for more scope.
Extended trot is not just a faster trot. In correct extension, the stride becomes longer while the rhythm and tempo remain controlled. If the horse speeds up, falls onto the forehand, or loses balance, the movement has become running rather than true extended trot.
