If you ask most people which operating system a racehorse uses, most of them would say none. And that’s quite explainable. Horse racing appears as an age-old sport, and on the surface at least, it appears as if it has nothing to do with technology.
But in reality, horse racing has become one of the most tech-forward sports out there, with piles of data and information that are processed on every single race. Lightweight GPS units transmit a horse’s position while it’s running, databases process race information, and broadcast systems turn telemetry into graphics. Then we have wagering platforms that handle huge volumes of transactions on big events in the blink of an eye.
So horse racing needs a powerful operating system that supports custom integrations and data processing. The truth is that beneath many systems like this sit technologies familiar to almost every modern software engineer, such as Linux. With that said, it is important to mention that racecourses and racing tech suppliers rarely publish a neat diagram highlighting the exact operating system that runs every server.
So, let’s find out how Linux, Real-Time OS, and open-source software are helping the horse racing industry do its thing.
The Horse Is Now a Moving Internet of Things Device
First, let’s talk about how data is gathered and why horse racing companies actually need a good operating system. For instance, the Gmax Race system used by Total Performance data and Equibase places lightweight GPS trackers on horses and streams a bunch of information, including position, speed, stride length, running order, timing, and more.
On top of that, this system is designed to operate without relying on ordinary cellular service or racecourse Wi-Fi, and its data can feed television graphics, display boards, and online visualizations.
StrideSAFE goes a step further, but from a different, often more important perspective. It is designed to make horse racing safer for horses. Its three-ounce GPS and accelerometer unit collects around 2,400 movement data points per second while a horse races, which allows algorithms to examine even tiny changes in gait that would be extremely difficult to observe with the naked human eye.
This technology is already used on big events like the Kentucky Derby and the Breeders’ Cup. But all of this data can also be used for Breeders’ Cup predictions. Expert handicappers often dig deep beneath the surface and want to see how a horse moves and performs before making a bet.
Why Is the Software Important?
A normal laptop can occasionally pause for an operating-system update without bringing Western civilization to an end.
An embedded tracking device has less freedom.
It has to wake sensors, timestamp measurements, process signals, manage wireless communication and keep doing those jobs predictably while the horse underneath it is travelling at racing speed.
That is the world of real-time computing.
A real-time operating system, or RTOS, is designed around predictable timing. Rather than concentrating primarily on giving a user a pleasant desktop experience, it makes sure important tasks happen within defined time constraints.
Public documentation does not identify the specific embedded operating system inside Gmax or StrideSAFE units, so naming one would be speculation. But Total Performance Data itself has described embedded real-time systems as directly relevant to its technology. When former Google engineering executive Jeremy Doig joined TPD’s board, he specifically referred to applying his background in “embedded realtime systems” to the company’s live sports telemetry.
Then the data leaves the horse and meets Linux.
Once information reaches servers, the engineering environment starts looking much more recognisable.
Linux has become a standard operating system for servers precisely because it is stable, configurable, and extremely well supported across networking, databases, and cloud infrastructure.
Horse-racing companies do not universally reveal their server operating systems, but one unusually transparent example comes from specialist sports technology company Mustard Systems. A current engineering role for its horse-racing team lists a stack including Linux servers, Python, C, Go, PostgreSQL, RabbitMQ, and Kafka.
Which makes sense.
Racing software often has similar requirements: process large data feeds, store history, move messages rapidly between services, and keep systems available when demand spikes.
Why Linux and Open Source Fit Racing So Well
- Horse racing creates an unusually awkward technical environment.
- A system may sit almost idle during part of the day and then become absolutely critical for several minutes.
- It must ingest information quickly. It may need to operate at geographically remote racecourses.
- Failures can become very public very quickly.
- And different companies need to exchange information despite running completely different internal systems.
- Linux, open APIs, and mature open-source technologies suit that world because engineers can build highly specialized systems without reinventing networking, databases, and operating systems from scratch.
Final Thoughts
The digital transformation of horse racing is quite easy to miss because the sport is wrapped around that traditional blanket that’s covering all the tech. But technology is already in horse racing, and the operating system is very important in order to process all of that information and make it understandable for humans.
