Quick Answer: How fast can an ostrich run? An ostrich can reach a commonly cited top speed of about 43 mph (70 km/h), making it the fastest-running bird in the world. Its long legs, powerful muscles, and efficient stride help it cover ground quickly, although the exact maximum speed has not been firmly established through direct measurements.
Ostriches are remarkable animals that combine size, speed, and endurance in a way few other land animals can. Although they cannot fly, they have evolved into exceptional runners, using their long legs, powerful muscles, and unique two-toed feet to travel across the open African savanna with remarkable efficiency.
During my time in Tanzania, watching wild ostriches cross open grasslands completely changed my perspective on these birds. At first they appear calm and almost effortless in their movements. Then, within just a few strides, they accelerate with surprising power, covering several meters with each step while using their wings to maintain balance at high speed.
In this guide, you’ll learn how fast an ostrich can run, how its top speed compares with humans, horses, lions, and cheetahs, what allows it to maintain such impressive endurance, and whether popular claims about ostriches reaching 50–60 mph are actually supported by scientific evidence.

The Top Speed of an Ostrich
An ostrich can reach a reported top running speed of about 43 mph (70 km/h), although the exact maximum is difficult to establish from direct measurements. The Smithsonian’s National Zoo explains ostrich speed, reporting that ostriches can sprint at this speed and run continuously at lower speeds.
Claims that ostriches can reach 45–60 mph are often repeated online. However, a study published in the Journal of Experimental Biology noted that reliable direct measurements of the ostrich’s maximum running speed were lacking, despite these widely reported figures.
Measured Speed vs. Common Claims
| Reported Speed | Evidence Level | Notes |
|---|---|---|
| 43 mph (70 km/h) | ⭐⭐⭐⭐⭐ High | Widely accepted top speed reported by major wildlife references |
| 45 mph (72 km/h) | ⭐⭐⭐ Moderate | Occasionally reported by reputable wildlife sources |
| 50–60 mph (80–97 km/h) | ⭐ Low | Frequently repeated online but lacks strong published evidence |
Although an ostrich’s maximum speed is impressive, its greatest advantage is not simply how fast it can sprint. What truly sets this bird apart is its ability to maintain 30–37 mph (48–60 km/h) over much longer distances than most other fast-running animals.

Why Are Ostriches So Fast?
An ostrich’s running speed comes from several physical adaptations working together. Its long legs, powerful muscles, and specialized feet help it take long strides and move efficiently across open ground.
But leg length alone doesn’t explain how an ostrich runs so fast. The structure of its feet, the way its muscles and tendons work together, and how it maintains balance all contribute to its distinctive running ability.
The way these bones, tendons, joints, and feet work together is explained in our detailed breakdown of ostrich anatomy and physiology.
Long Legs Create Longer Strides
One of the biggest reasons ostriches run so fast is their exceptionally long legs. An adult ostrich can cover 10 to 16 feet (3 to 5 meters) in a single stride, meaning it travels much farther with each step than most other animals.
Rather than increasing speed by taking more steps, ostriches increase speed by covering more ground with every stride. This makes their running style both fast and energy efficient.
Powerful Leg Muscles Generate Explosive Speed
An ostrich’s legs contain some of the strongest muscles found in any bird. These muscles generate the force needed for rapid acceleration while supporting a body that can weigh well over 300 pounds (136 kg).
Unlike flying birds, ostriches invest far more muscle mass in their legs than in their chest, allowing them to convert nearly all of their power into forward movement.
Two-Toed Feet Act Like Natural Running Shoes
Most birds have three or four toes. Ostriches have only two.
The larger toe supports most of the bird’s weight and ends in a thick nail that functions almost like a hoof, providing excellent traction on firm ground. The smaller outer toe helps maintain balance, especially when turning at high speed.
This unusual foot structure reduces weight at the end of each leg while improving stability and running efficiency.
Elastic Tendons Help Save Energy
Running isn’t only about muscle power. Ostriches also rely on long, elastic tendons that store and release energy with every stride.
As the foot lands, these tendons briefly stretch before springing back, helping propel the bird forward with less muscular effort. This natural “spring” effect reduces fatigue and contributes to the ostrich’s impressive endurance over long distances.
Wings Provide Balance Instead of Flight
Although ostriches cannot fly, their wings still play an important role while running.
When sprinting or changing direction, they spread their wings slightly to stabilize their bodies, much like a tightrope walker uses their arms for balance. This helps maintain control during sharp turns and sudden changes in direction while running across uneven terrain.
Physical Adaptations That Make Ostriches Fast
| Adaptation | How It Helps |
|---|---|
| Long legs | Increase stride length and ground covered per step |
| Powerful leg muscles | Generate rapid acceleration and high top speed |
| Two-toed feet | Improve traction, balance, and running efficiency |
| Elastic tendons | Store and release energy to reduce fatigue |
| Large wings | Provide balance and stability during high-speed running |
How Does an Ostrich’s Speed Compare to Other Animals?
Running at 43 mph (70 km/h) is impressive on its own, but comparing an ostrich’s speed with other animals makes its athletic ability even easier to understand.
Although the ostrich is the fastest running bird in the world, it is not the fastest land animal. Some mammals can reach higher peak speeds, while others rely on short bursts of acceleration rather than endurance.
The table below compares the ostrich’s speed with several well-known runners.
Ostrich Speed Comparison
| Animal | Top Speed | Faster Than an Ostrich? | Key Advantage |
|---|---|---|---|
| Ostrich | 43 mph (70 km/h) | — | Excellent endurance |
| Cheetah | 70 mph (113 km/h) | ✅ Yes | Fastest land animal |
| Lion | 50 mph (80 km/h) | ✅ Slightly | Powerful short bursts |
| Horse | 40–55 mph (64–88 km/h) | Sometimes | Depends on breed |
| Greyhound | 45 mph (72 km/h) | Slightly | Sprint speed |
| Human (Usain Bolt) | 27 mph (44 km/h) | ❌ No | World’s fastest recorded human |
Can an Ostrich Outrun a Human?
Absolutely.
Even the fastest human ever recorded, Usain Bolt, reached a peak speed of about 27 mph (44 km/h). An ostrich can exceed 43 mph (70 km/h) while also taking strides up to 16 feet (5 meters) long.
In a race across open ground, an ostrich would quickly leave even an Olympic sprinter behind.
Can an Ostrich Outrun a Horse?
It depends on the distance.
Many horses can reach speeds between 40 and 55 mph, meaning some breeds are capable of running faster than an ostrich during a sprint.
However, ostriches are exceptional endurance runners. They can maintain high speeds for much longer than many animals, making them surprisingly competitive over extended distances.
Can an Ostrich Outrun a Lion?
Often, yes.
Although lions can briefly reach speeds of around 50 mph (80 km/h), they usually maintain those speeds for only a short distance before tiring.
Ostriches rely on endurance rather than explosive acceleration. By maintaining a fast, steady pace and making quick changes in direction, they can often escape lion attacks before the predator closes the gap.
Can an Ostrich Outrun a Cheetah?
No.
The cheetah remains the fastest land animal, capable of reaching speeds of around 70 mph (113 km/h).
However, cheetahs can sustain these speeds for only a short time. Ostriches cannot match a cheetah’s maximum speed, but they can continue running long after a cheetah has slowed down.
Can an Ostrich Outrun a Car?
Not under normal conditions. Even a small passenger car can easily exceed an ostrich’s top speed on a paved road.
However, this comparison changes on rough terrain. Ostriches are built for uneven ground, where their balance, agility, and long strides allow them to move efficiently across grasslands and loose soil conditions that can challenge vehicles.
How Long Can an Ostrich Run?
Ostriches are not only the fastest-running birds; they can also sustain high running speeds. According to the Smithsonian’s National Zoo, ostriches have been observed running continuously at around 30–37 mph (48–59 km/h) and sprinting at up to 43 mph (69 km/h).
Their ability to travel efficiently on two powerful legs helps them cover ground across open habitats. However, maximum sprint speed and sustained running speed are different measurements, and the exact maximum running speed of ostriches has not been established through reliable direct measurements.
Why Can Ostriches Run for So Long?
Several adaptations allow ostriches to sustain high running speeds for much longer than most animals.
Their long legs reduce the number of strides needed to cover a given distance, making each step more efficient. Elastic tendons store and release energy like natural springs, reducing the amount of muscular effort required with every stride. Powerful leg muscles provide continuous forward propulsion, while an efficient cardiovascular and respiratory system delivers the oxygen needed to support prolonged exercise.
Together, these adaptations make the ostrich an exceptionally efficient long-distance runner rather than just a fast sprinter.
Top Speed vs. Endurance
Reaching maximum speed and maintaining it are two very different things.
An ostrich can briefly reach its top speed of about 43 mph (70 km/h), but it typically runs at a slightly lower pace when covering longer distances. This strategy conserves energy while still allowing the bird to stay well ahead of most predators.
| Running Style | Typical Speed | Purpose |
|---|---|---|
| Maximum sprint | Up to 43 mph (70 km/h) | Escaping immediate danger |
| Sustained running | 30–37 mph (48–60 km/h) | Covering long distances with less fatigue |
Why Endurance Matters More Than Top Speed
In the wild, survival rarely depends on reaching a record-breaking speed for a few seconds. Instead, it depends on staying fast long enough for predators to give up the chase.
Large predators such as lions rely on explosive acceleration but tire relatively quickly. Ostriches use a different strategy: maintaining a high, sustainable pace while covering large distances across open grasslands. This combination of endurance, efficient movement, and excellent balance makes them difficult targets despite being unable to fly.
Can an Ostrich Really Run 60 mph?
Online sources sometimes claim that ostriches can reach 60 mph (97 km/h). However, this figure should be treated with caution because it is not well established by reliable direct measurements or major wildlife references.
The commonly cited top speed for an ostrich is around 43 mph (70 km/h), although reported figures can vary between sources. Without reliable measurements supporting the higher figure, it is more accurate to use the commonly reported speed rather than present 60 mph as an established fact.
Ostriches are exceptionally fast runners regardless of whether the 60 mph claim is accurate. Their speed, long strides, and efficient movement help them travel quickly across open terrain and respond to potential threats.
Why Does the 60 mph Myth Exist?
There is no single source responsible for the claim. Instead, the figure appears to have spread as websites repeatedly copied one another over time without citing original research or measured observations.
This is a common example of how unsupported numbers can become accepted online through repetition rather than evidence.
When comparing wildlife facts, it’s always worth asking whether a number comes from a measured observation, a scientific publication, or simply another website repeating the same claim.
What Does the Evidence Suggest?
Reported ostrich speeds vary between sources, so it is important to distinguish commonly cited figures from claims that lack strong supporting evidence.
| Reported Speed | How to Interpret It |
|---|---|
| 43 mph (70 km/h) | Commonly cited maximum running speed in major wildlife references |
| 45 mph (72 km/h) | Reported by some wildlife sources, but not a universally established maximum |
| 50–60 mph (80–97 km/h) | Widely repeated online, but not well established by reliable direct measurements |
For a clear and cautious summary, about 43 mph (70 km/h) is a reasonable commonly cited estimate of an ostrich’s top speed. Higher figures should not be presented as confirmed without stronger supporting evidence.
Why Did Ostriches Evolve to Run So Fast?
Ostriches belong to a group of birds that evolved to live on the ground rather than rely on powered flight. Their evolutionary history is complex, and their flightlessness should not be understood as a single, deliberate change that happened simply because running became more useful.
In Africa’s open grasslands and semi-arid habitats, running offers important survival advantages. Being able to move quickly across open ground can help ostriches escape predators, travel between feeding areas, and navigate landscapes where shelter may be limited. Natural selection over many generations helped shape the traits that make modern ostriches such effective runners.
Their speed is therefore best understood as part of a broader set of adaptations to life on the ground, rather than as the result of one evolutionary change or a single need to outrun predators.
Built for Life on the African Savanna
The African savanna offers few places to hide.
Without dense forests or rocky shelters, large birds must rely on early detection and rapid escape. Ostriches have excellent eyesight that helps them spot predators from long distances, giving them valuable time to start running before an attack begins.
Instead of depending on camouflage or flight, they depend on speed, endurance, and awareness.
Speed Saves Energy Too
Running fast isn’t only about escaping predators.
An efficient running style also allows ostriches to travel long distances while searching for food, water, and suitable nesting areas. Covering more ground with less energy is especially valuable in habitats where resources can be widely scattered.
Their long strides and energy-efficient biomechanics make long-distance travel much less demanding than it would be for many other large animals.
Evolution Turned a Flightless Bird Into a Running Specialist
Many flightless birds became isolated on islands where predators were scarce.
Ostriches followed a very different evolutionary path.
Because they continued living alongside large carnivores, they developed into highly specialized runners instead of becoming slow-moving ground birds. Their anatomy reflects this trade-off: reduced flight muscles, exceptionally powerful legs, long elastic tendons, and a body designed for speed rather than flight.
Evolutionary Adaptations for Speed
| Adaptation | Survival Benefit |
|---|---|
| Long legs | Longer strides and higher speeds |
| Powerful leg muscles | Rapid acceleration and sustained running |
| Two-toed feet | Better traction and lower energy cost |
| Excellent eyesight | Earlier predator detection |
| Large body size | Longer stride length and stability |
| Reduced flight muscles | More energy invested in running |
Interesting Facts About Ostrich Speed
An ostrich’s running ability involves more than reaching a high top speed. Its balance, movement, and other physical adaptations help it navigate the open environments where it lives.
Their Long Strides Help Them Cover Ground
Ostriches have long legs that allow them to cover substantial ground with each step. Stride length changes with running speed, the individual bird, and the conditions, so claims of a fixed maximum stride length should be treated cautiously unless supported by a reliable source.
Their Wings Help With Balance
Although ostriches cannot fly, their wings still serve useful purposes. During running, wing movements can help with balance and directional control, particularly when the bird changes direction.
Young Ostriches Become Mobile Early
Ostrich chicks are able to walk soon after hatching and develop their running ability as they grow. However, young birds are more vulnerable than adults, and their survival depends on more than speed alone.
Speed Is Only Part of Their Defense
Running helps ostriches escape danger, but avoiding predators also depends on detecting threats and responding in time. Their keen eyesight can help them spot potential danger, while their powerful legs can deliver dangerous kicks when they need to defend themselves at close range.
