American Quarter Horse
Speed: Around 55 MPH
We had a bit of trouble considering which horse species to add to this list. While we loved the American Quarter Horse, it is actually the Thoroughbred Winning Brew that can move the fastest. However, this is not technically true. In our research, we found that the Winning Brew has the world record for the fastest speed from the starting gate on an official racetrack. However, this speed reach was around 43 mph. Winning Brew horses can reach up to 60+ mph if pushed to it. Yet it cannot hold to any high speeds for very long.
Meanwhile, the American Quarter Horse is capable of reaching near the record limits of the Winning Brew. At the same time, it can maintain higher speeds for a lot longer. They tend to top out around 55 mph at their fastest. Yet they could likely maintain a speed of 45 to 50 mph for quite a while, making them great horses to use for travel purposes. If you wanted to get somewhere quickly, of course. The Quarter Horse is actually only American too. It began here after extensive breeding involving English and Native Horses in the 1600s.
