RACING YOUNG HORSES IS NOT GOOD

The racing industry insists that starting horses young — and racing them at two years old — is not only harmless, but beneficial.

According to this narrative, early racing “strengthens bones,” prepares horses for long careers, and reflects what horses are “naturally built” to do.

It sounds reassuring.

It’s also deeply misleading.

The reality — supported by veterinary science (YOU can read the studies below) and by how every other equine sport treats young horses — is far more uncomfortable for racing.

This isn’t about whether a two-year-old can run. Of course they can.

The real question is what it costs them to do so — and how many never recover from that cost.

Research has shown that many lower limb growth plates (such as those in the cannon bone and pastern) may in some cases close by approximately 2.5 to 3 years of age in some Thoroughbreds.

Some studies place closure of the distal radius — a frequently cited example — at roughly 30 months, with variation between individuals.

But this is where the industry conveniently stops talking.

More detailed anatomical research demonstrates that key parts of the horse’s skeleton mature much later, particularly those most affected by racing:

– The spine (thoracic and lumbar vertebrae) continues maturing well beyond the age racing begins

– Studies examining vertebral growth plates in Thoroughbreds show closure occurring closer to 5–6 years of age, sometimes later

– The pelvis and supporting structures critical to balance, stride efficiency, and shock absorption mature on a similar timeline

Racing stresses the entire horse, not just the lower legs.

Pretending early limb maturity equals full skeletal readiness is scientifically dishonest.

Another common industry defence is that bone responds positively to loading, and that early exercise can strengthen the skeleton.

This point is often technically correct — and strategically abused.

Research does show that controlled, progressive loading can stimulate bone adaptation.

However, the same body of literature makes it equally clear that:

– Excessive high-speed loading increases injury risk

– Poorly managed workloads overwhelm tissue adaptation

– Tendons, ligaments, joints, and cartilage adapt more slowly than bone, making them vulnerable in young horses

Crucially, these studies do not conclude that early racing is beneficial.

They examine conditioning under controlled circumstances — not the commercial reality of racing, where young horses are pushed to peak performance quickly to justify their cost.

Bone can adapt BUT…

SO CAN IT FRACTURE!

Here’s the comparison racing avoids entirely.

Outside of racing, early high-intensity competition is considered irresponsible.

Across equestrian disciplines where soundness and longevity matter:

Dressage: Horses are lightly backed around 3–4 years, but serious collection and competition are delayed until 6–8+ years, when the spine and core musculature are mature

Show jumping: Progressive training is the norm, with higher fences and elite competition reserved for 5–7+ year-old horses

Eventing: Upper-level competition is typically restricted to fully mature horses, often 7–9 years old

Endurance: Many governing bodies impose minimum age limits (often 6 years or older) before horses can compete over long distances, explicitly to protect immature skeletons

These disciplines are guided by veterinary research, decades of injury data, and lived experience. They know what happens when immature horses are pushed too hard, too soon.

If intense athletic competition at two years old were truly beneficial, racing would not be the global outlier.

But it is.

Racing often cites studies showing that horses who begin training or racing earlier sometimes have longer or more successful racing careers.

What those statistics fail to capture is who never makes it into the dataset.

– Horses who break down early

– Horses who are quietly retired due to chronic injury

– Horses who are discarded, sold, or disappear into slaughter pipelines

These horses don’t become “statistics.” They become invisible losses.

A system that celebrates the few who survive early stress while normalising the destruction of the many is not evidence-based. It’s exploitative.

Every other equine sport waits for maturity because waiting works.

Racing doesn’t wait because waiting costs money.

And that difference explains everything — from early breakdowns to the relentless pipeline of horses who vanish from the track and reappear at knackeries and abattoirs.

Racing young horses isn’t about what’s good for horses.

It’s about how fast they can be used — and how cheaply they can be replaced.

Horses are the ones whose welfare is repeatedly sacrificed in silence while the spotlight shines elsewhere.

The horse racing industry can spin it.

They can shine it.

They can wrap it in warm PR language.

But the truth remains.

And that’s why Meet Our Horse Meat will never stop pulling the shine off the rot beneath.

Help us raise awareness.

Boycott horse racing – including saying #nuptothecup.

Support our sanctuaries – they are filled with off the track horses.
