LARC Testing with Prime Equine
A simple yet powerful way to 𝐜𝐡𝐞𝐜𝐤 𝐲𝐨𝐮𝐫 𝐡𝐨𝐫𝐬𝐞’𝐬 𝐡𝐞𝐚𝐥𝐭𝐡 𝐚𝐧𝐝 𝐟𝐢𝐭𝐧 𝐞𝐬𝐬 𝐚𝐟𝐭𝐞𝐫 𝐩𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞.
WHAT IS LARC?
LARC is a cutting-edge test that gives us instant feedback on a horse’s internal stress and systemic function - right after a run or workout.
It tells you if the effort was
-
𝐭𝐨𝐨 𝐡𝐚𝐫𝐝
-
𝐭𝐨𝐨 𝐞𝐚𝐬𝐲,
-
or 𝐣𝐮𝐬𝐭 𝐫𝐢𝐠𝐡𝐭.
In less than 20 minutes, this test evaluates key biomarkers that reflect the possibility of:
-
Lung inflammation
-
Respiratory bleeding (EIPH - even with or without Lasix)
-
Muscle fatigue
-
Pain or systemic strain
-
Overall fitness adaptation
This isn’t a guess or a gut feeling. It’s a science-based way to see what your horse is telling you - from the inside out.

Why I Chose to Become LARC Certified
I’ve been in this game a long time - as a mounted shooting competitor, former barrel racer, and retired equine first aid instructor. I’ve seen the heartbreak of horses pushed past their edge—not from neglect, but from a lack of information.
We ask for 110% effort every time we swing a leg over, and most horses will give it - even when their lungs are struggling, their body is fatigued, or their internal systems are fighting to keep up.
I chose to bring LARC to Prime Equine because it’s objective, fast, and rider-friendly. It lets us finally ask the right question:
“Was that too much? Or is my horse truly conditioned to handle this level of work?”
LARC fits seamlessly into my approach: prehab over rehab, putting the horse first, and optimizing for longevity, performance, and recovery.
WHEN SHOULD I LARC TEST?
LARC should be used:
-
Right after competition or training exertion
-
Before pushing conditioning levels
-
When something feels “off,” but nothing’s visible
-
To monitor Lasix effectiveness
-
To screen for the potential of respiratory bleeding risk
-
As a routine wellness check-in throughout a performance season
Also consider LARC if your horse:
-
Refuses the gate or alley
-
“Shuts down” under saddle
-
Recovers slowly after runs
-
Shows coughing or nasal discharge
-
Is labeled “lazy,” “dull,” or “difficult”
-
Suddenly underperforms without a clear cause
Sometimes it’s not the training. It’s not the footing. It’s not even their mind.
It’s their lungs, muscles, or systemic inflammation - and LARC lets us find out right now.
The Results?
Faster horses. Better Recovery. Smarter conditioning.
Once we test, you’ll get:
•Immediate results right after the testing
•A personalized conditioning plan in 2–3 days
•Support options that may include nutrition tweaks, postural rehab, or strategic rest
•A retest in 3–5 weeks to track measurable progress (additional fees apply)
LARC helps you train smarter, not just harder and test results are just the beginning. At Prime Equine, we help your horse actually improve based on what we find. You can add on:
-
Nutrition consults to support speed horses
-
Pasture to Performance online course for foundational strength
-
Work the Walk Masterclass for maximizing biotensegrity in the body
-
Postural & Biomechanic Virtual Lessons
-
Nerve Release Bodywork
We don’t stop at the data - we build the plan that changes the outcome.
