Yes, horses are built to run. They are also built to pull heavy weights, though this is secondary to their ability to run, and travel long distances. Not all horses are fast, they do have three basic 'running types' Sprinter, Middle Distancer, and stayer. Sprinters are chunky with big hindquarters. Middle Distancers tend to have slightly bigger hindquarters like a sprinter, but a bit longer in the body like a stayer. Stayers have long, lean, typically tall bodies, they can travel distances at speeds slightly slower than a sprinter.
Yes, they can run or trot for miles to avoid predators.
Horses are built to run, with powerful muscles in the fore- and hind-quarters, long spindly legs, large lungs and a stout heart.
probably not because most horses are built for speed and donkeys are not
zebras can run faster than horses
Horses can run free if they are treated cruelly. If they are treated well they wouldn't run away.
Horses run on purely green technolgy. Wind turbines and solar panels are not built using green tech, but do operate green.
They just aren't built for it. Quarter horses have the ideal barrel racing conformation, with their well defined hindquarters, they are able to jump into a run from the starting gate and turn on a dime. Arabians are not built much like quarter horses. They can be good starter barrel horses, but if you want to go to the higher levels you need a horse with the build of a quarter horse.
Horses learn how to jump and run as fast as they could.
Yes, horses have evolved to be fast and efficient runners.
Yes. They can.
Horses are a flight animal, they will run away from danger.
Horses do because dogs get tired faster.
