Thoroughbred racing · Health & anomaly detection

By the time you can see it, it has been coming for weeks.

A catastrophic breakdown is almost never sudden. The stride starts changing long before anyone can see it. Alogo — a small device placed on the girth — gives your team a second set of eyes on the whole string, flagging the first signs of musculoskeletal trouble weeks before they reach the eye, even an expert's.

The fear every barn lives with

Musculoskeletal injury is racing's worst nightmare - and the cruelest part is how quietly it begins.

The onset is silent. Subtle stride changes build for weeks while the horse still works, still cleans the feed tub, still looks sound to a sharp trainer and a good vet. By the time something is visible, the damage is often already done: a career interrupted or ended, months of rehab, real money in diagnostics and surgery.

You don't buy a horse. You buy a future - a campaign, black-type, a stallion or broodmare career, a return on a serious investment. And all of it rests on one fragile thing: staying sound.

Lost timeMusculoskeletal injury is the leading cause of lost training days, retirement and breakdown in racing.
Real moneyDiagnostics, surgery and months of rehabilitation - and a major orthopedic injury can erase a large share of a horse's value.
Invisible earlyThe warning is in the data weeks before it's in the leg. Until now, no one was reading it stride by stride.

Every breeze, read

The warning is in the stride long before it's in the leg. Now you can read it.

The answer

See it early. Act in time.

Alogo learns each horse's own normal, then watches for it to drift - session after session, breeze after breeze. One small Swiss sensor on the girth line captures 150+ parameters per stride at 100 Hz and turns them into a single, honest signal your team can act on.

Eyes on the whole string

A second set of eyes across the entire barn - never tired, never rushed, never assuming a quiet horse is a sound one.

Weeks of warning

Anomaly detection up to ~5 weeks before clinical signs are visible - the window in which rest, not surgery, is still the answer.

One line per horse

Every morning, one clear status per horse. Green: carry on. Yellow and Red: look closer, today, at the right horse.

An alert is not a diagnosis. It is an invitation to look - at the right horse, at the right moment, while you still have time. Alogo complements your team; it never replaces the trainer's eye or the vet's judgment.

The morning read

Your whole string, on one screen.

Every horse, one line: the last five breezes, health status, anomaly score and what to do next - so you know exactly which horse to look at before you leg up.

What it watches for

The signals that show up in the stride first.

Alogo measures locomotion objectively, breeze after breeze, and flags deviations from the horse's own normal - the kind tied to the conditions that quietly end campaigns.

Locomotor patterns commonly associated with
Bone fatigue / SBDSubchondral bone disease
Suspensory desmitisLigament stress
FracturesCondylar or chip fractures
Joint issuesSynovitis or hock inflammation

Alogo detects locomotion anomalies and deviations in movement - not a clinical diagnosis. It points your team to the horse and the moment worth examining; the diagnosis is always the veterinarian's. Detection performance varies by pathology type and is strongest for progressive conditions.

Selected by the industry's own veterinarians

Put to the test in the AAEP's racehorse sensor study.

AAEP 2025 study
700+two-year-olds monitored
4sensors made the final analysis — Alogo among them
4,252recorded breezes

In 2025 the AAEP - the American Association of Equine Practitioners, the leading US body of equine veterinarians - ran an independent, year-long, multi-vendor field evaluation of wearable sensors for the early detection of musculoskeletal injury in two-year-old Thoroughbreds. More than 700 two-year-olds wore sensors through high-speed breezes; six sensor companies were selected. Independent analysis was led by Dr. Peta Hitchens, University of Melbourne.

  • Alogo was selected as one of the six - and is publicly named as one of just four companies whose data met the bar and was analyzed - chosen by the industry's own veterinary body, and among the few whose data actually made the cut.
  • A field test at serious scale: 4,252 recorded breezes across 561 two-year-old Thoroughbreds, with 221 musculoskeletal injuries reported across the program (142 bone, 79 soft tissue).
  • The AAEP's analysis found injury risk was greatest in horses flagged red or yellow at their last breeze, and those that accumulated red flags over the prior 90 days - around twice as likely to sustain a musculoskeletal issue. That's the same red/yellow + trend logic Alogo's alerts are designed around. (Program-level finding across the analyzed sensors, not an Alogo-specific result.)
  • By way of context, 50% of study participants raced in 2025, against a 39.6% industry average.
  • The AAEP concluded wearable sensors "show promise... and can serve as an effective complement to veterinarian and trainer oversight," while noting they "require further refinement before becoming a mandated device" - with four companies successfully completing the study objectives.
"This study was not intended to validate the use of sensors as a tool to scratch horses from competition on race day but rather to validate if sensors can provide more information about a racehorse's physical condition prior to a horse being entered to race."- Dr. Sara Langsam, AAEP Racing Committee Chair

Performance, furlong by furlong

Health first - but every furlong counts.

Beyond health, Alogo breaks the work down furlong by furlong: speed, stride length and cadence, where top speed is reached, and how balance shifts through the run. See which part of the work cost time - and how to ride it better next breeze.

New · Performance monitor

Every horse against its own normal.

The Performance monitor tracks each horse's vitals - stride length, cadence, stride height, speed - and compares every work to that horse's own usual range, never to the barn average. Baselines are workout-conditioned: a breeze is compared only to breezes, a canter to canters - so the numbers reflect the horse's condition, not how hard the rider worked that day. What it's watching for: creeping fatigue. Stride length and cadence sliding below a horse's own range at the same work intensity are often the first quiet signs it needs easing - visible in the numbers before they're visible from the rail. One vital drifting = watch; two or more = attention.

For both sides of the stable

One sensor. Two kinds of value protected.

For Owners - protect the asset
  • Guard a major investment whose whole value rests on soundness - a serious orthopedic injury can erase a large share of a horse's worth across resale, black-type and breeding.
  • Career longevity - catch the drift while rest still fixes it, before it becomes surgery and a season lost.
  • Lower veterinary spend over a career by acting before small becomes serious.
  • Real transparency on the condition of what you own, session after session.
  • Your data stays yours - you decide who sees each horse's results, and we never sell your data.
For Trainers - augment your eye
  • A second set of eyes across the entire string - one clear line per horse, every breeze, so the quiet horse hiding a problem doesn't slip through.
  • Objective soundness & readiness - know which horse to push and which to ease, before a workout proves it the hard way.
  • Confident return-to-work monitoring after a layup, tracked stride by stride.
  • It augments your eye and never overrides it - an alert tells you where to look; the call stays yours.
What's at stake

A season, a stakes campaign, a breeding career - all resting on one thing staying sound. Protect the whole string.

The economics

A fraction of the bill it's built to get ahead of.

A racehorse in training runs about $125 a day - and roughly $1,000 a month (~$12,000 a year) in veterinary care alone. With around one in four horses hurt each year, the question isn't whether you'll pay for injuries - it's whether you catch them early or late.

What an injury costs

Lameness work-up$115 - 160
Radiographs / tendon ultrasound$200 - 250
Joint or tendon therapy$430 - 1,000+
Shockwave, per treatment~$350
Months of layup & rehab board~$59 / day

Operating figures (day-rate, monthly veterinary spend, ~25% annual injury rate, 100-horse barn) are industry-typical estimates shown for illustration; procedure costs are from the AAEP Equine Veterinary Fee Survey (DecadeOne / VMG 16), 2024. The whole-string figure uses the 51+ volume rate ($79 / horse / mo). Alogo helps your team act earlier - it does not diagnose, and does not guarantee prevention or savings.

The math is simple

One injury caught early can pay for itself many times over.

See what a second set of eyes finds on your own horses, before anyone else can.

A real case · anonymized

When the eye said "fine" and the data said "look again."

Caught in time

A trainer was certain the horse was fine. Across several sessions, Alogo flagged a locomotion profile quietly drifting from the horse's own normal. After the repeated alerts, a veterinary exam found early inflammation in both front fetlocks. No fracture. No surgery. Caught in time, the horse needed only rest and care.

That's the difference between a few weeks off - and a campaign, and a large share of value, lost. The alert didn't make the diagnosis. It pointed the vet to the right horse, at the right time.

Technology built by someone who has lived the pressure of top-level competition and the bond with a horse - not by a lab disconnected from the ground.

Our conviction

Only through regular, consistent monitoring - using Alogo technology - can owners, trainers and veterinarians proactively support the soundness, performance and well-being of their equine athletes.

Frequently asked questions

No - and that's not its role. Alogo is a second set of eyes that watches continuously and objectively. It flags where to look and when; the trainer keeps the call and the veterinarian makes any diagnosis. As the AAEP put it, sensors are "an effective complement to veterinarian and trainer oversight."

The AAEP (American Association of Equine Practitioners) ran an independent, year-long field evaluation of wearable sensors on more than 700 two-year-old Thoroughbreds during high-speed breezes. Six companies were selected; Alogo is one of four whose data met the bar and was analyzed. It is a multi-vendor study with no public ranking or winner - the program-level findings are reported by the AAEP, not Alogo-specific results.

Alogo flags deviations from a horse's own normal as the stride starts to change - up to around five weeks before clinical signs become visible. "Early" means objective locomotion change before it's visible to the eye, even an expert's - not a prediction of a specific injury. Detailed peer-reviewed field-study results are publishing soon.

Yes - separately from the AAEP project. The Alogo Move Pro was validated against the Qualisys optical motion-capture system (the worldwide reference) and published in Sensors (Guyard et al., 2023). The single-sensor anomaly-detection method is published (Savoini et al., 2025).

Yes. The Racing Edition sensor is integrated into the overgirth and changes nothing about the work. The automated Alogo Sync Box uploads the whole string seamlessly, and stable reporting fits every horse on one screen - one clear status line per horse, every morning.

Your data is yours. You decide who has access - typically you, your trainer and your veterinarian. We never sell your data, and we don't share an individual horse's results with third parties without your permission. Real transparency on the condition of what you own, session after session.

Yes - and we'd encourage it. Alerts and reports are easy to share with your vet, so the right horse gets examined at the right moment. Alogo points to the horse and the timing; the diagnosis always stays with your veterinarian.

Alogo is a Swiss company, and the Move Pro is already used by leading stables across the US and Europe. In many regions we can come to your barn to fit your string - ask us about yours.

No. Start with a 90-day pilot on up to 10 horses at the $99/horse/mo pilot rate - baselines for every horse plus your first stable report - then roll into the 12-month program, or send the sensors back. We tailor the program to the size and season of your operation.
