The ostrich runs faster than any other two-legged animal. Its has a top speed of 40 mph, and it can run at 30 mph for up to 30 minutes.
Ostriches are able to achieve high speeds and levels of endurance due to their massive thigh muscles, long legs, stable joints and unique toe structure. The thigh muscles and long legs allow ostriches to take up to 16-foot strides when running. Their joints prevent sideways movement, freeing up muscle energy that could otherwise be wasted maintaining stability. The ostrich's soft, taloned, two-toed feet aid in balance, shock absorption and traction, while its tip-toe running posture gives the ostrich a spring-like launch with every step.Learn More
