Reins & Martingales

Reins are your primary line of communication from hand to bit, so feel and grip matter. Lengths scale from pony through to horse so you can keep a natural hand position without excess tailing, and many designs include rein stops for use with a running martingale.

Martingales can support a consistent contact when fitted and used appropriately for your discipline. Running martingales guide the reins through rings and only engage beyond a set head position; standing martingales attach to the noseband to help limit sudden upward carriage; bib styles keep the forks aligned.

Choosing the Right Set-Up

Start with your discipline and typical conditions. For everyday hacking and schooling, rubber-grip reins can help maintain feel in rain. Plain leather reins are popular for shows and riders who prefer a smoother release. If you’re considering a martingale, choose the style recommended by your instructor for your horse and riding goals, and confirm it’s permitted under current rules.

Fit & Sizing

Reins should allow a comfortable hand position without excessive tailing. Check buckle/stop placements, especially if using rein stops with a running martingale. For martingales, measure standing height and adjust chest, neck and fork so the aid sits neutrally at rest and only engages as intended.

How Reins & Martingales Works

Reins transmit your contact to the bit; surface texture influences hand grip and the “release” sensation. Martingales route the reins (running) or limit upward head carriage (standing) within set parameters. Correct adjustment is essential so the aid remains passive until needed. Always follow current discipline guidelines and seek instruction for fitting and use.

FAQs

What’s the difference between running and standing martingales?
A running martingale routes the reins through rings and engages when the horse raises the head beyond a set point; a standing martingale connects to the noseband to limit upward head carriage.

Which reins should I use for wet weather?
Rubber-grip or rubber-inset reins can help maintain feel in rain. Keep them clean so the texture remains effective.

How long should reins be?
Choose a length that allows your normal hand position without excessive tailing. Pony and cob sizes are shorter; full and extra-full are longer. Try with your usual bit and bridle.

Do I need rein stops with a running martingale?
Yes, rein stops are typically used to prevent the martingale rings from sliding onto rein buckles or the bit. Position them according to fitting guidance.

Are plaited/laced reins only for shows?
They’re popular in the show ring but can be used for schooling if you prefer the feel. Pick a texture that supports a steady, comfortable contact.

When should I replace reins or a martingale?
If you notice cracked leather, stretched holes, loose stitching, worn rubber or damaged metalwork, replace the item for safety and consistency.
