The ostrich can stand more than 9 feet tall, weigh 350 pounds and run faster than anything else on two legs; but in the end, this living feather duster is all avian. 08-01-2006 // Doug Stewart. THE OSTRICH, the world’s largest living bird, is also the fastest runner on two legs. In short bursts, a lion or a cheetah can overtake it. But an ostrich can motor for 10 miles straight at a steady 30 miles an hour—faster than Lance Armstrong in a time trial. Research biologist Jonas Rubenson of Northeastern University is one of several scientists eager to find out how they make it look so easy Best Answer: the average is about 30-60 mph. this is all ostriches, old and young. a certain age group, say middle aged, ban run about 40-50. mind you, 60 is VERY fast, and not many ostriches can run at that rate.  How ostriches use their 'springy' legs to help them run faster and longer. By Niall Firth for MailOnline. Updated: 07:05 EST, 1 November 2010. 15 View comments. 15. View. comments. Ostriches are able to run so fast over long distances because they use half as much energy as humans do to run at their top speed. Scientists who compared ostriches and humans running discovered that the huge birds can store twice as much energy in their leg tendons as we can. To find out how an ostrich runs the researches fitted reflective markers to the joints of five humans and five tame ostriches. They then carried out a detailed analysis of their gait and movements as they ran on a custom-built running track 50 metres long. Yes. In fact, an Ostrich can outrun a tiger. A tiger can run about 35 miles per hour, while an Ostrich can reach speeds of up to 60 miles per hour. 9 people found this useful. Edit. Ostrich isn't a slouch The Ostrich is the fastest living animal on two feet. It can reach speeds of up to 60km/h. An ostrich can run up to 35 miles (56.3 kilometers) per hour with its powerful legs. Ostrich isn't a slouch The Ostrich is the fastest living animal on two feet. It can reach speeds of up to 60km/h. Though they cannot fly, ostriches are fleet, strong runners. They can sprint up to 43 miles (70 kilometers) an hour and run over distance at 31 miles (50 kilometers) an hour. They may use their wings as rudders to help them change direction while running. An ostrich's powerful, long legs can cover 10 to 16 feet (3 to 5 meters) in a single stride. These legs can also be formidable weapons. Ostrich kicks can kill a human or a potential predator like a lion. Each two-toed foot has a long, sharp claw 1 Ostriches can also defend themselves with a 4-inch claw on each foot. 2  Ostrich brains are as big as a walnut and smaller than their eyes. 3  They are not particularly intelligent, but with the largest eyeball of any bird, they can see as far as 2.2 miles (3.5 km). 1 In fact, its kick is strong enough to kill a lion. 2  Ostriches can also defend themselves with a 4-inch claw on each foot. 3  Ostrich brains are as big as a walnut and smaller than their eyes. 4  They are not particularly intelligent, but with the largest eyeball of any bird, they can see as far as 2.2 miles (3.5 km). The fastest thoroughbred racehorse has reached top speeds of 55mph, almost double that of Usain Bolt’s 100m world record top speed. However, thoroughbred’s aren’t just fast, they’re also known for their stamina and can maintain a pace of 16 mph for 60 miles. Talk about the ultimate ultra marathoner. Sarah, a cheetah residing at the Cincinnati zoo is undoubtedly the fastest of all land mammals. On June 20, 2012 she ran 100m in 5.95 seconds with a top speed of 61 mph. That’s nearly 4 seconds faster than Bolt’s 100m world record and more than double his top speed. mendobrew.com.
