1 mile
5 minutes....less or more
By 'Kentucky Horse Race' I'll assume you mean Kentucky Derby as there are hundreds of races in Kentucky. The Derby is a mile and one fourth in length.
1 1/8 mile (or 9 furlongs)
The legend of Hidalgo talks about a down-and-out cowboy in 1890 and how he travels on his horse to Arabia to compete in a deadly cross desert horse race.
They vary in length, but as your question is posted in the KY Derby category I will say one and one quarter miles since the Derby is held at Churchill Downs and that is the length of that particular course.
The Quarter Horse is the fastest horse in the world, for a quarter of a mile. The Thoroughbred, most often used in horse racing, has more endurance for an entire mile, but still cannot beat the Quarter Horse in a quarter-of-a-mile race. Hence the name 'Quarter Horse'. This is exactly what you want in a horse when you are working cattle - short bursts of extraordinary speed.

The Kentucky Oaks race covers 1 1/8 miles.
ummm is it also about a horse race?. If yes it could be Hidalgo starring Viggo Mortensen
The Quarter Horse is fastest for sprints. They race a quarter-mile. Thoroughbreds are fastest for anything longer than that. Arabians are best for endurance. The fastest mile for a horse was around 1 minute, 35 seconds. This record was set by the TB racehorse Salvador.
