Ever wondered why some horses in racing circles are called geldings? You might have seen the term on a racecard or heard it mentioned during a commentary, but not many people know what it truly means.
Understanding what a gelding is may give useful context if you follow racing and read form. It also explains why certain horses tend to feature more often in particular types of races.
This guide sets out what a gelding is, why some horses are gelded, how it relates to performance, and how geldings compare with stallions in the UK racing scene. Read on to learn more.
A gelding is a male horse that has been castrated, which means its testicles have been removed. The procedure is carried out by a qualified vet and is a routine part of equine management in British racing and training yards.
You will see plenty of geldings on UK racecourses, especially in jump racing. They are often gelded to help manage behaviour, as reduced hormone levels can lead to a more settled temperament. That makes day-to-day handling, schooling over obstacles, and life in a busy yard or on a crowded raceday easier for everyone involved.
On racecards, a small letter ‘g’ next to a horse’s name indicates it is a gelding. It is one of several quick-reference details alongside age, trainer, and recent form. While some people like to note whether a runner is a gelding, decisions about who to follow usually rest on a mix of factors, including performance history, distance, ground and the trainer’s record.
If you do decide to try your hand at horse racing betting, remember to do so responsibly and within your means; never wager more than you can afford to lose.
Stallions, which are entire males, can show strong natural instincts, particularly around mares. In a training environment this can mean distraction, assertive behaviour, or tension in the string, which is not ideal when a horse needs to concentrate on learning its job.
Gelding can reduce those pressures. With fewer hormonal distractions, many horses find routine work more straightforward, from cantering in company to standing in the parade ring. That can also help with travel, veterinary care and general yard management, where calm behaviour keeps horses and people safer.
There is also a practical breeding angle. If a colt is not considered a future stallion based on pedigree, conformation or early results, connections may opt to geld him so the focus is entirely on a racing career. This often leads to longer time on the track, particularly in National Hunt racing, where horses typically run for several seasons and the emphasis is on stamina and consistency rather than future stud value.
Being a gelding does not change a horse’s raw ability, but it can influence how that ability is applied. Many trainers find geldings easier to keep focused through the daily cycle of work, rest and racing, which helps when building fitness for a campaign. A horse that is less distracted is less likely to waste energy before or during a race, which supports more even performances.
This is one reason you see so many geldings in National Hunt races, where demands are high, distances are longer and jumping accuracy matters. Observationally, yards often describe geldings as more straightforward to condition for that kind of repeated effort across a season.
That said, outcomes still depend on the individual. Pedigree, soundness, training, race tactics and conditions on the day all play a part. Geldings regularly enjoy lengthy careers, and their names can reappear year after year in the same meetings, which is reflected in entry lists and results published by the British Horseracing Authority (BHA).
The core difference is biological. Geldings have been castrated, while stallions are entire males. Because of their breeding potential, successful stallions on the Flat often progress to stud duties after racing. That future value shapes how they are campaigned and which races they contest.
Geldings, by contrast, race without any breeding plans in mind. They are especially common in jump racing, where a steady temperament and the ability to train on from year to year are prized. You will still find geldings on the Flat, but the mix tends to tilt towards stallions at the top level because of stud considerations.
Racecards reflect these categories with shorthand: g for gelding, c for colt if under five, and h for an older entire horse. Alongside age, sex and recent runs, this could help to build a quick profile of each runner.
In practical terms, geldings can bring a few helpful qualities to the table. A more settled nature often makes them easier to train, and that steadiness can show during long campaigns or in the heat of a big raceday. It is no surprise that at major jump meetings, such as the Cheltenham Festival, the fields are dominated by geldings, reflecting the demands of those races.
That does not mean geldings are inherently faster or more talented. Performance is shaped by fitness, form, ground, trip, pace and the way a race unfolds. Plenty of stallions excel, especially on the Flat where speed and future breeding value align.
If you are studying a race, noting whether a runner is a gelding or an entire horse is simply one more piece of context. Used alongside the usual clues in the form book, it helps explain career paths and why certain names are still around season after season. Understanding that picture could make racecards easier to read and adds colour to the stories behind the horses you watch.
