Skinny Fences, Big Confidence: How to Stop Runouts and Ride Accuracy Questions Like a Pro

If you’ve ever had a horse lock onto a cross-country line like a hero, then suddenly hit the brakes at a skinny like it’s a trapdoor to another dimension, this is for you.

In the Boyd Martin Eventing Program this week, we held a XC Training Huddle with Boyd, and a theme kept popping up across multiple riders, multiple horses, and even Boyd’s own five-star round: accuracy questions (skinnies, corners, narrow lines) demand a different ride than big, galloping fences. And when the horse is green, talented, or just a little too pleased with themselves, the “easy cruise” feeling can be exactly what sets you up for a runout.

This post focuses on the single most valuable takeaway from the session: how to ride skinny fences and accuracy jumps so your horse stays committed, straight, and confident, without turning every approach into a wrestling match.

You’ll learn:

• Why skinnies create runouts even when everything else feels great
• The riding adjustments that make accuracy fences clearer for the horse
• How to school skinnies so they become “nothing jumps”
• What to do immediately after a runout so it doesn’t become a habit

Why skinny fences cause runouts (even on a good round)

Skinny fences are not “hard” because they’re big. They’re hard because they’re specific.

A horse can jump a wide table or rolltop slightly left or right and still get away with it. A skinny fence doesn’t allow that. If the horse misreads the question, loses focus for one stride, or drifts through a shoulder, they suddenly discover a very convenient option: go around.

Boyd put it simply when reviewing Jenny’s runout at a wedge-style skinny:

• “If you sort of go for a little bit of that forward one and they misread it, it sort of leaves that space where they can run out and glance off.”

That “space” is the whole problem. Accuracy fences punish vague riding and reward clarity.

The sneaky danger: “It’s going too nice”

One of the most interesting patterns in the session was that the runouts didn’t always happen when things felt messy. They happened when things felt smooth.

Boyd described Jenny’s round as “almost going too nice,” and later said something similar about his own five-star moment: the course was going well, so he assumed the horse would simply lock on and jump.

That’s the trap. When everything feels easy, riders often:

• Soften too early
• Allow the line to get casual
• Ride for flow instead of commitment

On a skinny, that can be one stride too late.

The most effective fix: ride skinnies deeper, not longer

If you take one technical change from this session, make it this: ride accuracy fences on a deeper distance.

Not a chip. Not a panic pull. A deliberate decision to hold the horse together for one more stride, so the horse arrives closer, straighter, and more certain.

Boyd’s advice to Jenny was clear:

• “At these lower levels, I’d hold him back and get him really, really close and deep to the jump.”

Why a deeper distance helps a green horse

A green horse often runs out because they are unsure, not naughty. A longer takeoff spot can feel like:

• Too much air time to think
• Too much room to drift
• Too much opportunity to decide “no thanks”

A deeper distance:

• Keeps the horse’s body straighter
• Reduces the drift window
• Gives the horse a clearer “job” right in front of them

It’s not about riding timid. It’s about riding definite.

Position and aids: “Anchor them back” and keep the shoulders straight

Accuracy fences expose two common rider leaks:

1. The horse falls out through a shoulder
2. The rider’s position gets tipped forward when the horse hesitates

Both showed up in the ditch discussion too, but they matter just as much for skinnies.

Stay in a secure, slightly more “back seat” balance

When a horse stops or chips in, riders often get tipped up the neck. Boyd noted this with Victoria at the ditch:

• The horse “screeches to a halt”
• The rider’s upper body slides forward

On skinnies, the same thing happens when the horse backs off at the last second. A secure, balanced position gives you a chance to keep riding, instead of getting launched into survival mode.

Use the rein that prevents the escape

In Jenny’s case, the horse repeatedly ran out left. Boyd’s correction was practical:

• If he runs off left, stop and turn him right
• Hold the right rein on takeoff
• Be ready to prevent the left shoulder from escaping

This is an important mindset shift: you’re not just aiming at the jump, you’re managing the exit door.

What to do after a runout (so it doesn’t become a hobby)

Runouts can become a pattern fast, especially for greener horses. Boyd called it out:

• “They’re creatures of habit.”

Once a horse discovers they can slide left and avoid the question, they will absolutely consider doing it again unless the rider changes the conversation immediately.

Step 1: correct the direction of the escape

If the horse runs out left, Boyd recommended turning them right. Why?

• It interrupts the horse’s chosen path
• It prevents them from “winning” by heading toward comfort (friends, trailers, warm-up)
• It resets the line with intention

Step 2: make the jump unavoidable (in schooling)

For training, Boyd suggested building skinnies with V-poles or side rails to funnel the horse:

• “So it sort of funnels him over it.”
• “If he goes to run out, he actually has to jump over something.”

This is classic confidence-building: you remove the option to dodge, and the horse learns the correct answer without drama.

Step 3: let the horse know it matters (without losing your kindness)

Jenny voiced what a lot of good riders feel:

• She cares about the horse
• She worried she scared him
• She didn’t know how firm to be

Boyd’s response was basically: you can be kind and still be clear. When the horse is new at the level, you may need to be “a little over-holding or a little strong” so the horse understands the job.

That’s not punishment. That’s leadership.

Schooling skinnies: build confidence through repetition and variety

One of the best practical themes in the session was that confidence is built through:

• Repetition
• Variety
• Correct first experiences

Boyd and Lillian both emphasized that doing the same ditch or the same skinny at the same venue can create a false sense of security. The horse learns that specific jump, not the concept.

Lillian’s point was sharp:

• Your horse might jump it at home
• Then stop at a show
• So you need different venues and different versions of the question

A simple skinny schooling progression (green horse friendly)

1) Start with a funnel

• Use V-poles or guide rails
• Keep the jump inviting and low enough to stay confident

2) Ride it deeper than you think you need

• Practice the “one more stride” feel
• Prioritize straightness and commitment over flow

3) Add approach variety

• Left lead turn, angle slightly right if the horse wants to run out left
• Approach off different lines so the horse learns to lock on, not memorize

4) Reduce the funnel over time

• As the horse gets confident, make the question more honest
• Keep the ride the same: definite, straight, committed

Rider mindset: assume they might stop (for now)

This was one of the most useful mental tools of the whole session, especially for riders who tend to be generous, optimistic, and fair.

Lillian suggested that for the next couple of rounds, Amy should think before every fence:

• “She could stop at this.”

Not forever. Not as a fear spiral. As a temporary way to keep your brain switched on and your ride proactive.

Because the truth is: once a green horse has stopped, they’ve earned a little extra respect from your preparation.

Boyd backed that up in his own way: when horses are very green, he rides stronger and more definite until they understand the job, then he gets softer again.

Actionable takeaways (steal these for your next schooling day)

• Ride skinnies on a deeper distance. Hold the horse together for one more stride so they arrive closer and straighter.
• Treat accuracy fences differently than galloping fences. You can’t “coast” to a skinny and expect it to work.
• Manage the escape shoulder. If the horse runs out left, ride to control the left shoulder and support with the opposite rein.
• After a runout, interrupt the habit fast. Turn the horse away from the escape line and re-present with a clearer plan.
• Use V-poles and funnels in schooling. Remove the option to dodge so the horse learns the correct answer confidently.
• Be kind, but be definite. A green horse sometimes needs a firmer ride so “jump” becomes non-negotiable.
• Don’t let “going well” make you casual. The smoother it feels, the easier it is to under-ride the accuracy question.
• School the concept, not the location. Practice skinnies and similar questions at different venues so confidence travels.
• Use a mindset cue if you need it. For a couple of rounds: “They could stop at this” keeps you proactive, not reactive.
• Position is your insurance policy. A secure, balanced ride helps you stay effective when the horse hesitates.

Closing: make skinnies boring (that’s the goal)

The most encouraging part of this session was the tone from the coaches: these issues are normal, especially at a move-up, and they’re fixable with clear riding and smart repetition.

Skinny fences are not a personality test. They’re a clarity test!

Ride them deeper, straighter, and more deliberately than the rest of the course. School them with funnels until the horse understands the job. And remember: the goal is not to make skinnies feel dramatic.

The goal is to make them boring.
