A dairy cow can run at an average speed of about 15 to 20 miles per hour, with some sources noting that cows can reach top speeds of up to 25 miles per hour for short bursts. However, bulls tend to be faster, potentially reaching speeds up to 30 miles per hour. Dairy cows typically run slower than bulls due to their bulky udders and other physical factors. The running speed can vary based on factors like breed, age, weight, health, terrain, and motivation (such as escaping danger).
In summary, a dairy cow can run roughly 15-20 mph, with short bursts up to 25 mph.
