the fastest horse on record was the racehorse Secritariat who ran an estimated 55 miles an hour
The racehorse Boundless was not only fast but also a beauty.
Apparently there were three horses at this one track that could run a furlong in about 9 seconds. Usually it is fun in 10-12 seconds.
Secretariat, the all-time fastest racehorse, could run at a top speed of about 45 miles per hour. However, I would say that an average racehorse can run at around 30 to 35 miles per hour. I really hope that this answered your question.

The racehorse Boundless was not only fast but also a beauty using linking words.
A fast race horse would be "ein schnelles Rennpferd".
He Is A Sure Bet.

Strong and powerful determind,respecting,and smart.
The Gallimimus was a 4 meters long and could reach speeds of 65 km/h. About as fast as a modern racehorse.
A racehorse at full speed varies from 35-45 miles per hour.
