What is the average pace when a horse running?

There's no single "average pace" for a horse running because it depends on many factors:

* Breed: Some breeds, like Thoroughbreds, are bred for speed and will naturally run faster than others.

* Training: A well-trained racehorse will be significantly faster than a horse used for trail riding.

* Distance: A horse running a sprint will have a much faster pace than one running a long-distance race.

* Terrain: Running uphill or on uneven ground slows a horse down.

* Condition: A healthy, well-fed horse will run faster than one that's tired or injured.

Here are some general examples of typical speeds for different types of horse running:

* Racehorse (Sprint): Up to 45 mph

* Racehorse (Long Distance): 25-35 mph

* Trail Riding: 5-10 mph

* Gallop (Casual): 15-25 mph

Remember: These are just averages. A horse's actual speed can vary greatly depending on the factors mentioned above.
