The Burghley Horse Trials, part of the eventing competition, features a cross-country course that typically spans approximately 6,500 to 7,000 meters (about 4 to 4.5 miles). The competition also includes dressage and show jumping phases, but the cross-country phase is the most notable for its challenging terrain and obstacles.

It depends on how fast the horse is going, and what kind of horse it is. Most horses run about 40 mph. Speed*Distance=Time, so about 5 minutes, give or take some seconds.
The fastest breed of horse is the American Quarter horse, which can reach up to 55 m/h (88 km/h) for a short distance. A Thoroughbred horse can only run as fast as 45mph.
a work or a breeze or can even be called a 2 minute lick
The distance a spooked horse would run with no obstacles to stop it varies based on factors such as its level of fear, environment, and training. In some cases, a spooked horse may run several miles before calming down, while in other instances, it may only travel a short distance before stopping.
You have to run beside it
I am sure any type COULD be a racehorse but not all horses are cut out to be one. Most racehorses are quarter horses or thoroughbreds. A quarter horse is the fastest horse but can only run a short distance. A thoroughbred isn't as fast but can run for a larger period of time. I hope I helped out some ;)
The definition of a distance racehorse depends on what part of the world you're from. In the US, a distance horse is one that can run well and win races over a mile in length, i.e. a common distance for UK racehorses.
