Question 3. Can you use the same horse for an entire game?
No. Polo ponies run the equivalent of one to two miles during a seven-and-a-half-minute chukker, so they must be rested frequently. At the high-goal level, players ideally will have a fresh horse every period although many will “double” on their best ponies. Even at this level, it’s rare but not unheard of for a pony to be played three chukkers in the same game—it happened in the famed International Matches between England and the United States.
