What is a three horse race?

Answer 1

The Kentucky Derby has 20 horses. But yeah, it's different from race to race. It's rare that there is more than 20 horses, but it happens. Usually 10-20, but sometimes only 2. But the Grand National has 40 horses.

Answer 2

Horse racing has often been called the "sport of kings". For as long as people have domesticated horses, it has been a sport. It is enjoyed by those who bet on the races and by the those who do not.

Answer 3

When two or more horses race each other or when the news media comments on the standings of the candidates in a political race (as though it were a horse race).

Answer 4

This could literally be race with only three horses or more likely a race where there are three contenders who are considered the most likely to win.
