Is the Arabian the fastest horse for long distances?

Answer:

Arabians were bred for endurance because they were ridden in areas with harsh conditions etc.

I don't know if they are the fastest breed of horse, but I do know that purebred Arabians are generally very high-strung and can be very aggressive. However, mixed breeds usually have a much more laid-back temperament.

Hope this helps!

The fastest breed is the American Quarter Horse which can reach 55 miles per hour for a quarter of a mile. Thoroughbreds however can keep 40 miles per hour for a mile but even the fleetest Arabian could not achieve the speed of a Thoroughbred or Quarter Horse. Therefore the Arabian is not the fastest.
