Gridwork for horses is one of the most reliable ways to sharpen a jumper, settle a green horse, and build the rhythm and footwork that translate into clean rounds in the ring. By setting poles and small fences at carefully measured distances, you ask the horse to think for himself, find his own stride, and use his body correctly — without the rider micromanaging every step. Whether you ride at riding-club level or compete to BS Discovery and beyond, gridwork is where the small problems get fixed and the good habits get built.

What Is Gridwork for Horses?
A grid — sometimes called a gymnastic — is a line of poles or fences set at fixed, related distances so the horse takes a predictable number of strides between each element. The simplest grid is a row of trotting poles. The most advanced is a bounce-to-one-stride-to-two-stride combination over verticals and an oxer. Whatever the shape, the principle is the same: the distances do the schooling, leaving the rider free to sit quietly and ride forward.
Gridwork sits at the heart of British show jumping coaching. Riders such as William Fox-Pitt, Mary King, and the late Tim Stockdale built grids into their weekly schooling for one reason: a horse who has trotted, cantered, and jumped through a correctly-measured grid does not need to be told where to take off. He learns to find the spot himself, and that self-reliance is what holds up under pressure on a course.
Why Gridwork Works: The Biomechanics
When a horse meets a fence on his own stride, his hindquarters engage, his back lifts through the bascule, and his forelegs snap up cleanly. When he meets it long, flat, or chipped in, that biomechanical chain breaks — he flattens, drops a leg, or rushes. Grid distances are calculated to put a horse on his correct take-off point regardless of what the rider does. Repeated through a grid, the horse stores that take-off feeling in muscle memory.
Trotting poles in particular train the horse to lift the shoulder, flex the hocks, and step underneath himself — the same engagement you want for a quality canter and a clean jump. This is why dressage riders also use ground poles for suppleness work, even if they never go near a fence.
Benefits of Gridwork for Horse and Rider
- Improves balance and rhythm — the horse learns to keep an even canter through related distances rather than rushing or backing off.
- Builds topline and core strength — repeated bascule over fences develops the muscle the horse needs to jump well over time.
- Sharpens footwork and reflexes — bounces and one-strides force the horse to use his hind end quickly and accurately.
- Improves confidence in green horses — small, related fences feel manageable and predictable.
- Cures rushing and backing off — placing poles and tight grids slow a quick horse down and encourage a slow, careful one to commit.
- Trains the rider’s eye — counting strides through a grid teaches feel for distance without needing to chase a single fence.
- Cardio-light schooling — gridwork is mentally demanding without being physically punishing, ideal for fittening days.
Standard Distances for Gridwork
Distances are measured in feet, between the centre of one element and the centre of the next. Adjust them slightly for very large horses, very small ponies, or unusual canter strides. The figures below assume a 12-foot canter stride for an average 16hh horse.
| Element | Distance | Notes |
|---|---|---|
| Trotting poles | 4 ft 6 in (1.4 m) | Use 4 to 6 poles in a row |
| Canter poles | 9 to 10 ft (2.7 to 3 m) | One canter stride between each pole |
| Trot to first fence | 9 ft (2.7 m) from last pole | Place pole encourages take-off |
| Bounce | 10 to 12 ft (3 to 3.7 m) | No stride between fences — lands and jumps |
| One stride | 21 to 24 ft (6.4 to 7.3 m) | One canter stride between fences |
| Two strides | 33 to 36 ft (10 to 11 m) | Two canter strides between fences |
| Three strides | 45 to 48 ft (13.7 to 14.6 m) | Standard related distance |
For ponies under 13.2hh, shorten one-stride distances to around 18 ft and two-strides to 30 ft. For very long-striding warmbloods, you may need to add 6 inches to a foot to keep the horse from getting deep.
Six Gridwork Exercises Every Rider Should Try
1. Four Trotting Poles
The starting point for every horse, every season. Four poles set at 4 ft 6 in, ridden in a steady working trot. Walk through first to check the spacing, then trot through both reins. Add a fifth and sixth pole once the horse stays even and through. This is the exercise to build engagement, suppleness, and a regular rhythm.
2. Trot Pole to Cross-Pole
Three trotting poles followed by a 9 ft placing distance to a small cross-pole. The placing pole sets the take-off so the horse cannot rush or chip. Ideal for first-time jumpers, riders learning to fold, and any horse coming back into work after a break.
3. The Bounce Grid
Two cross-poles set at 11 ft (no stride between them). Approach in a balanced canter; the horse lands and immediately jumps the second fence. Bounces force the horse to snap his front end up quickly, sit on his hocks, and use his core. Start at 50 cm and only raise once the horse is comfortable. Two bounces in a row (three fences) is plenty for most schooling sessions.
4. One-Stride Double
A vertical to a vertical, set at 22 ft. Approach in a quality, forward canter. The one-stride distance teaches the horse to land in canter and balance for the next fence — the foundation of every double in a course. Make the second fence half a hole higher than the first to encourage the horse to power off the hindquarters.
5. Bounce-One-Stride Combination
Cross-pole, 11 ft to a vertical, 22 ft to an oxer. This three-element grid is the bread and butter of British show jumping schooling. The bounce gets the horse engaged, the one stride asks for a quick rebalance, and the oxer at the end rewards a forward, confident jump.
6. Fan Gridwork on a Curve
Three small fences placed on an arc, with the inner distance shorter than the outer. The rider chooses the line, and the horse must adjust his stride to fit. This teaches the rider to look up and ride the line, and the horse to listen to leg and seat between fences — exactly what you need for a tight jump-off.
Building a Grid Safely: Equipment and Setup
- Use safety cups on the back rail of any oxer — required by British Showjumping in competition for good reason.
- Round, painted poles roll if the horse hits them. Square or homemade poles can cause falls.
- Wing standards are safer than uprights with no flag — they encourage the horse to stay straight.
- Measure with a tape, not paces — a 4 in error compounds across a five-element grid.
- Surface matters — a properly maintained sand or rubber arena is essential. Avoid grids on hard or deep ground.
- Brushing boots and overreach boots protect the horse’s legs from the inevitable knock or self-strike.
- Have a ground person the first time a horse goes down a new grid — they can adjust distances quickly if needed.
Common Gridwork Mistakes (and How to Fix Them)
- Building too big, too soon. A grid teaches a horse through repetition, not effort. Keep heights at 60 to 80 cm for schooling and only raise the final fence as a reward jump.
- Wrong distance for the horse. A horse rushing through a one-stride is usually telling you the distance is short. Add 6 in and try again before assuming the horse is the problem.
- Too many elements. Five fences in a row is plenty for most horses — beyond that, the horse tires and quality drops.
- Riding the grid, not the canter. Set up a strong, balanced canter on the approach and let the grid do the work. Do not chase, hold, or fiddle.
- No warm-up. Always trot poles before jumping a grid. Cold muscles plus repeated bascule equals soft tissue injury.
- Repeating the same grid every session. Variety keeps the horse mentally fresh. Change the shape, height, or order every week.
Gridwork for Different Horse Types
The Rusher
A horse who flattens and accelerates needs short, tight distances and lots of placing poles. Set a one-stride at 21 ft instead of 24, and put a pole on the ground in the middle of the distance. The horse cannot rush without hitting the pole, and within three or four passes most rushers settle.
The Backer-Off
The opposite — a horse who chips in or stops at the base. Use bigger fences with more spread (low oxers rather than tall verticals) and slightly long distances to encourage the horse to commit forward. A short bounce-to-one-stride often unlocks confidence quickly.
The Green Horse
Keep it simple. Trotting poles to a cross-pole, then trotting poles to two cross-poles in a one-stride. The aim is to teach the horse what is expected, not to test what he can do. Three or four sessions of low, simple grids before introducing a bounce.
The Show Horse Coming Back from a Layoff
Trotting poles for two weeks, then placing poles to small cross-poles. Build to one bounce, then a one-stride, then full grids over a four to six week period. Older horses in particular benefit from this slow rebuild — sudden gridwork after a layoff is one of the most reliable causes of suspensory and back strains.
How Often Should You Do Gridwork?
Once a week is the sweet spot for most horses in active work. Twice a week is reasonable in the pre-season build-up, but no more than that — gridwork is concussive on the legs and hocks and needs balancing with hacking, flatwork, and rest days. Out-of-season, drop to once a fortnight or replace fences with raised canter poles.
A typical schooling week for a competition horse might look like this: Monday hack, Tuesday flatwork, Wednesday grid, Thursday hack or rest, Friday flatwork, Saturday warm-up jump school, Sunday show or rest. The grid replaces a course-jumping day, not a flat day.
Gridwork FAQ
What is the ideal distance between trotting poles?
For an average 16hh horse, 4 ft 6 in (1.4 m) between poles. Shorten to 4 ft for ponies and 13hh-and-under, or stretch to 5 ft for very long-striding warmbloods. Always walk the distance first.
Can I do gridwork with a young horse?
Yes — from four years old onwards, once the horse is established in walk, trot, and canter under saddle. Start with trotting poles only, then introduce a single cross-pole at the end of the line of poles. Young horses should not be jumping bounces or one-strides regularly until they are physically mature, generally from age five or six.
What height should the fences be in a grid?
Schooling grids are built between 50 cm and 90 cm for most horses. The principle is that the grid trains technique, not effort, so keep the heights conservative. The final fence may be slightly larger as a confidence-builder, but the rest stay low.
Do I need a trainer for gridwork?
For a first grid, yes — a knowledgeable ground person prevents the most common mistakes (wrong distances, fences too big, horse too tired). Once you have ridden through a few correctly-measured grids and learned to feel the take-off, you can practise simple grids on your own. Anything technical — bounces, complex combinations, or grids over 1.10 m — needs a trainer or experienced eye.
Is gridwork safe for older horses?
Yes, with sensible adjustments. Lower the heights, reduce the number of elements, and use trotting poles or canter poles between fences rather than back-to-back jumps. Many horses in their late teens and early twenties continue to enjoy gridwork — it keeps them supple and engaged without the cardiovascular demand of a full course.
Pair gridwork with steady flatwork, varied pole exercises, and a fittening programme that supports the demands you are placing on the horse.
