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.
Can anyone tell me if this is Nacho below? If so, then this is really a great photo, because of Nacho.
