Ostriches are famous for being the largest birds on Earth, but their size is only part of the story. These remarkable birds are also among the fastest animals in their environment. In fact, the ostrich holds the title of the fastest bird on land.
Many people first become curious about ostriches when they see videos of them sprinting across the African savanna. Their long legs move with incredible speed, covering huge distances in just a few seconds.
During my time in Tanzania, watching ostriches move across open grassland was always impressive. At first they appear calm and almost slow. But the moment they start running, the power and speed of these flightless birds becomes obvious.
So how fast can an ostrich run? The answer might surprise you.

Key Facts About Ostrich Speed
- Top speed: 43 mph (70 km/h)
- Sustained running speed: 30–37 mph
- Stride length: 10–16 feet
- Fastest bird on land
- Can outrun humans easily
Quick Answer
An ostrich can run up to 43 miles per hour (70 km/h), making it the fastest bird on land. In addition to its top speed, an ostrich can maintain a steady running speed of 30 to 37 mph (48–60 km/h) for extended distances thanks to its powerful legs and long stride length.
The Top Speed of an Ostrich
The maximum speed of an ostrich is about 43 miles per hour (70 kilometers per hour). This makes it the fastest running bird in the world.
Unlike many animals that rely only on short bursts of speed, ostriches can also maintain high speeds for longer distances. Their strong legs and long stride length allow them to keep moving quickly across open terrain, which is essential when escaping predators in the African savanna.
Another interesting aspect of ostrich speed is the difference between their top speed and their sustained running speed.
| Speed Type | Average Speed |
|---|---|
| Top Speed | Up to 43 mph (70 km/h) |
| Sustained Running Speed | 30–37 mph (48–60 km/h) |
This combination of speed and endurance is one of the reasons ostriches have survived for millions of years in environments where predators are always nearby.
Why Ostriches Are Such Fast Runners
Ostriches did not become fast by accident. Their bodies are specifically adapted for running across open landscapes like the African savanna.
Several physical traits contribute to their impressive speed.
Physical Traits That Make Ostriches Fast
| Trait | Benefit |
|---|---|
| Long legs | Longer stride length |
| Strong leg muscles | Explosive acceleration |
| Two-toed feet | Better balance and speed |
| Lightweight bones | Reduced body weight |
| Large wings | Help with balance while running |
Long and Powerful Legs
The most obvious feature of an ostrich is its long legs. These legs contain powerful muscles that allow the bird to generate strong forward movement with each step.
An ostrich can cover 10 to 16 feet (3 to 5 meters) in a single stride, which is one of the main reasons it can reach such high speeds across open terrain.
Because their stride length is so large, ostriches do not need to take as many steps as smaller animals when running.
Lightweight Body Structure
Although ostriches are large birds, their bodies are relatively lightweight compared to mammals of similar size.
Birds have specialized bone structures that reduce weight while maintaining strength. This helps ostriches accelerate quickly and maintain speed over long distances.
Two-Toed Feet
Most birds have three or four toes on each foot. Ostriches only have two toes, which is unusual among birds.
One of these toes is large and strong and acts almost like a hoof. This structure improves balance and allows the bird to push off the ground efficiently while running.
This unique foot design helps reduce resistance and makes their running movement more efficient.
How Fast Can an Ostrich Run Compared to Humans?
Even the fastest humans cannot compete with an ostrich in a race.
The fastest recorded human runner, Usain Bolt, reached about 27 miles per hour (44 km/h) during his world-record sprint.
An ostrich, on the other hand, can reach 43 mph, which means it can run significantly faster than even the best human athletes.
This difference becomes obvious when comparing stride length as well. While humans rely on quick steps, ostriches move forward with extremely long strides that cover several meters at a time.
If a person tried to outrun an ostrich, the bird would quickly leave them behind.
Animal Speed Comparison (Including Humans)
| Animal | Top Speed | Notes |
|---|---|---|
| Ostrich | 43 mph | Fastest bird on land |
| Cheetah | 70 mph | Fastest land animal |
| Lion | 50 mph | Short burst predator |
| Horse | 40–55 mph | Strong endurance |
| Greyhound | 45 mph | Fastest dog breed |
| Human (Usain Bolt) | 27 mph | Fastest recorded human |
You might notice that humans appear in the table as well. From a biological perspective, humans are technically part of the animal kingdom, which makes the comparison useful when discussing running speed. Including the fastest recorded human runner helps illustrate just how remarkable the ostrich’s speed really is.
Can an Ostrich Outrun a Horse?
Another common question is whether an ostrich can outrun a horse.
Horses are among the fastest land animals and can reach speeds between 40 and 55 mph depending on the breed and conditions.
In a short sprint, a horse may be faster than an ostrich. However, ostriches have excellent endurance and can maintain high speeds for longer distances.
Their ability to keep moving quickly across open terrain allows them to escape danger in many situations.
Can an Ostrich Outrun a Car?
At first, this might sound like a funny question, but many people really do wonder whether an ostrich could outrun a car. The short answer is no, at least not under normal conditions.
An ostrich can run at speeds of up to 43 mph (70 km/h), which is incredibly fast for a bird. However, even a small car can usually travel much faster than that. In most real-world situations, a car would easily outrun an ostrich on an open road.
That said, the comparison becomes more interesting when you think about acceleration, terrain, and maneuverability.
Ostrich vs Car on Short Distances
On a short stretch, an ostrich can accelerate surprisingly quickly. Its long, muscular legs allow it to build speed in just a few strides. In the first few seconds of movement, an ostrich may look much faster than people expect.
A car still has the advantage, but the ostrich’s quick acceleration is one reason so many people are impressed when they see one running in the wild.
Terrain Makes a Big Difference
Cars perform best on roads and smooth surfaces. Ostriches, on the other hand, are built for rough, open terrain like grasslands and savannas.
This means an ostrich can move efficiently across uneven ground, change direction quickly, and keep its balance far better than a vehicle could in the same environment. So while a car is faster in terms of top speed, an ostrich is much better adapted to natural landscapes.
Why the Comparison Matters
Questions like can an ostrich outrun a car, help put ostrich speed into perspective. Saying an ostrich can run at 43 mph is impressive, but comparing that speed to a car gives readers a much clearer mental image.
For example, many residential streets have speed limits close to the ostrich’s maximum speed. That means a running ostrich can move about as fast as a car driving through a neighborhood.
Once you picture that, the bird’s speed feels much more real.
Why Speed Is Essential for Ostrich Survival
Speed is not just impressive. It is essential for survival.
The African savanna is home to many dangerous predators, including lions, cheetahs, hyenas, and African wild dogs. Because ostriches cannot fly, running is their primary defense mechanism.
When threatened, an ostrich usually chooses to run instead of fighting. Their long strides allow them to create distance quickly, making it difficult for predators to catch them.
These physical traits make the ostrich perfectly adapted to life in open environments where speed is often the only way to escape predators.
How Ostriches Use Their Wings While Running
Although ostriches cannot fly, their wings still serve several important functions.
When running at high speeds, ostriches extend their wings slightly to help maintain balance. This helps stabilize their bodies while moving across uneven terrain.
Their wings also assist when changing direction quickly. This ability can be useful when avoiding obstacles or escaping predators.
In some situations, the wings act almost like rudders, helping control movement while the bird slows down.
How Long Can an Ostrich Keep Running?
Another impressive ability of ostriches is their stamina.
Many animals rely on short bursts of speed, but ostriches can maintain relatively high speeds for extended periods. They are capable of running at about 30 mph (48 km/h) for long distances.
This endurance allows them to travel across large areas of the savanna while searching for food or avoiding predators.
Because of this combination of speed and stamina, ostriches are difficult targets for many predators.
