Making a horse faster comes down to five things: structured training, proper nutrition, strategic riding, appropriate surface conditions, and adequate recovery. No single trick transforms a slow horse into a fast one, but improving each of these areas compounds into measurably better speed. Whether you’re racing, barrel racing, or simply want a more responsive ride, the principles are the same.
Build Speed Through Interval Training
The most effective way to increase a horse’s top speed is high-intensity interval work mixed with slower, longer-distance days. The goal is to develop anaerobic capacity, the energy system your horse relies on during bursts of speed. Most professional trainers avoid pushing horses to full speed in training. Instead, they work at 70 to 85 percent of maximum race speed to build fitness without breaking the horse down.
A common approach is “breeze” work: fast galloping over short distances at roughly 75 percent effort, done once every seven to ten days. Some trainers prefer galloping closer to maximum speed but space those sessions out to once every five days. Between fast days, your horse should be doing slower aerobic work like trotting and easy cantering to build the cardiovascular base that sustains speed.
There are two main ways to structure the speed progression. You can start with very short bursts near top speed and gradually extend the distance your horse holds that pace. Or you can set a fixed distance and slowly increase the speed over weeks. Both work. What doesn’t work is training at 95 to 100 percent effort repeatedly. Pushing a horse to absolute maximum too often can reverse the physiological adaptations you’re trying to build, essentially making the horse slower and more injury-prone over time.
Fuel for Sprint Performance
Speed demands glycogen, the stored form of sugar in muscle tissue that gets burned rapidly during intense effort. That means a performance horse’s diet needs to include adequate soluble starch and sugars so the small intestine can absorb them and pack the muscles with fuel. Grain-based concentrates (oats, barley, corn) are the primary source of this fast-burning energy.
Fat is useful for endurance work but less so for sprinting. Keep dietary fat at or below 10 percent of the total diet for horses focused on speed. Fat burns slowly and fuels lower-intensity effort. It won’t help during the 30- to 90-second window where your horse needs explosive power. The bulk of caloric energy for a speed horse should come from digestible carbohydrates, supplemented with quality forage for gut health and fiber.
Hydration and electrolyte balance matter too. A horse that starts a workout even mildly dehydrated will fatigue faster and recover more slowly. Free access to water and a salt block should be non-negotiable, with additional electrolyte supplementation during heavy training periods or hot weather.
How Stride Length and Frequency Create Speed
A horse’s velocity is the product of two things: how long each stride covers and how many strides it takes per second. Faster horses tend to have longer strides rather than dramatically quicker leg turnover, though both contribute. Training that encourages a horse to open up its stride, through hillwork, pole exercises, and controlled gallops on good footing, can improve the distance covered per stride without the horse working harder.
Flexibility and core strength play a role here. A horse with a supple back and strong hindquarters can drive more powerfully off each stride, converting muscle effort into forward motion more efficiently. Regular groundwork, stretching exercises, and varied terrain help develop this. Stiff, short-strided movement wastes energy and caps your horse’s speed ceiling regardless of fitness level.
Rider Position and Aerodynamic Drag
Your position in the saddle has a bigger effect on speed than most riders realize. Aerodynamic drag accounts for roughly 17 percent of the total mechanical power a galloping horse produces. That’s a significant chunk of energy spent just pushing through air. The modern jockey’s crouched position exists specifically to reduce this drag, and the principle applies to any rider asking a horse for speed.
Staying low over the horse’s neck, keeping your body compact, and minimizing how much of your profile catches the wind all help. In racing, the difference between first place and fifth place is only about 2 percent in average speed. A 13 percent reduction in aerodynamic drag could account for that entire gap. You don’t need to ride like a jockey in every discipline, but when you’re asking for speed, getting off the horse’s back and into a forward two-point position lets the horse move more freely and cuts wind resistance at the same time.
Drafting behind other horses also matters in competitive settings. Research on nearly 50,000 race starts found that horses spending more time in a drafting position behind other runners consistently posted faster average speeds. For a horse that drafts for 75 percent of a race, the benefit is worth three to four finishing positions. Pacing strategy, staying tucked behind the field before making a late move, is a legitimate speed tool.
Surface Conditions Affect Speed Directly
The ground your horse runs on changes how fast it can go. Firmer surfaces generally allow faster times. Data from over 437,000 race starts on turf tracks shows that summer conditions, when the ground is drier and firmer, produce significantly higher speeds (averaging 16.7 meters per second, roughly 37 mph) compared to softer winter footing (15.1 meters per second, about 34 mph). That’s a difference of nearly 3 mph based purely on surface conditions.
If you’re training for speed, choose firm, well-maintained footing. Deep, muddy, or overly soft ground forces the horse to expend more energy per stride just to maintain balance, leaving less power for forward motion. Hard-packed surfaces are fast but increase concussion on joints, so there’s a tradeoff. Synthetic or well-groomed arena footing that’s firm but has some give tends to offer the best combination of speed and joint protection for regular training.
Genetics Set the Ceiling
Some horses are simply built to be faster than others, and genetics determine where the upper limit sits. In Thoroughbreds, a single gene called myostatin largely dictates whether a horse is suited for sprinting or distance. Horses with the CC variant of this gene develop more fast-twitch muscle fiber and excel at short, explosive races under 1,600 meters. The CT variant favors middle distances, while TT horses are built for stamina over longer races.
Heart size is another genetic factor. A Thoroughbred’s heart pumps about 35 liters of blood per minute at rest, seven times more than a human heart. Horses with unusually large hearts, like the legendary Secretariat and Phar Lap, had even greater capacity to deliver oxygen to working muscles. You can’t change your horse’s genetics, but understanding your horse’s natural strengths helps you set realistic goals and train for events that match its body type. A stocky, muscular horse will likely never be a distance champion, but it might be devastatingly fast in short bursts.
Recovery Makes the Fast Work Possible
Speed training only works if your horse recovers fully between hard sessions. After maximum exertion, blood lactate (the byproduct of anaerobic effort that causes the burning sensation in fatigued muscles) takes time to clear. Studies show that even after 10 minutes of walking recovery, lactate levels remain elevated above resting values, and heart rate can take several hours to return completely to baseline after intense exercise.
Practically, this means spacing hard workouts at least five to seven days apart. Between fast sessions, keep the horse moving with light hacking, easy trotting, and turnout. Active recovery, where the horse walks and trots at low intensity the day after hard work, helps clear lactate faster than complete rest. Adequate sleep, consistent turnout time, and attention to hoof and joint health all contribute to how quickly your horse bounces back and how much speed it can sustain over a training cycle.
Overtraining is the fastest way to make a horse slower. If your horse seems flat during workouts, reluctant to extend, or takes longer than usual to catch its breath, back off the intensity. The adaptations that build speed happen during recovery, not during the workout itself.
