Hopples 101: Quick Fit Guide for Harness Racing Horses 🐴🏁

November 15, 2025 | Kate Attard

Fitting hopples can feel like a dark art, but here’s a simple rule of thumb to make it easier:

Rub at the back?
➡️ They’re too long.

Rub at the front?
➡️ They’re too short.

Rub at both the front and back?
➡️ They’re way too short. Your horse needs more room to stride.

How to Measure Hopples Properly (Step-by-Step)

1. Stand the horse up square

The horse should be:

  • relaxed

  • weight even on all four feet

  • standing naturally

Point of buttock ➜ directly above the point of hock
They should sit in a straight vertical line when the horse is standing square.

This ensures:
• the horse isn’t standing under themselves
• they’re not stretched out behind
• you’re measuring from a true, natural stance
• hopple length matches their real stride, not a distorted one

This is one of the biggest mistakes people make, if the horse is camped under or stretched back, every measurement will be wrong.

✅ 2. First measurement: Girth line ➜ Point of hock

This gives you your baseline stride length.

📏 Girth line ➜ Hock = Base hopple length

✅ 3. Second measurement: Point of hip ➜ Back of fetlock

(Keep the tape straight, not curved.)

This is the measurement most experienced harness racing people use. It matches hopple length to the horse’s natural reach.

This helps ensure they’re not:
• over-reaching
• restricted
• losing balance
• shortening their stride at speed


📏Point of Hip ➜ Back of fetlock = Stride reach check

✅ 4. Compare BOTH measurements

Together they give you:

  • Base stride (girth → hock)

  • Natural reach (hip → fetlock)

Use both to find the correct starting hopple length.

✅ 5. Add your trainer adjustment

Based on gait + preference:

Pacers: add +1 inches either shorter or longer

  • Long-action pacers may need slightly more

  • Shorter-bodied horses may need slightly less

✅ 6. Measure both sides

Horses aren’t perfectly symmetrical.
Use the length that gives the best rhythm, not necessarily the longest or shortest.

✅ 7. Fit hopples + WALK first

Walk for 1–2 minutes to feel for natural swing and relaxation before trotting or jogging.

✅ 8. Jog slowly — the rhythm tells the truth

Correctly fitted hopples should give:

  • even stride

  • no pulling

  • no rushing

  • no “falling out of stride”

  • a free, balanced motion

If it feels forced, short, choppy, or unbalanced, the length is wrong.

If your hopples were off and caused a little rubbing…
