What Is a Chukka in Polo? The Seven-Minute Clock Set by a Horse's Lungs

Amanda's first verdict on polo's periods of play was that they seemed "very, like, iffy." Pete had just told her they last six or seven minutes, with four to six of them per match depending on who's playing, and she wanted to know why nobody had picked a number. So what is a chukka in polo? It's one period of play, about seven minutes long, and a match has somewhere between four and eight of them. The number looks arbitrary because the horses set it.

What Is a Chukka in Polo, Exactly?

A chukka (also spelled chukker) is a single timed period of play in a polo match, usually seven minutes long, and a full match is made up of four to eight of them.

Under the Hurlingham Polo Association's rules in Britain, the clock runs seven minutes and then a bell rings. Play doesn't stop at the bell. It continues until the ball goes out of play or for another 30 seconds, whichever happens first, and then a second bell ends the chukka. Club matches often run four or six chukkas, and the biggest matches go to eight. There's a short break between chukkas and a longer one at halftime. The halftime break is when the crowd walks out onto the field for the divot stomp.

Timed to the Horse, Not the Fans

Pete gives the reason on-mic: "The whole reason the chukka is that six or seven minutes... that's generally how long a horse can really last." A polo pony spends a chukka sprinting, stopping, and turning hard with a rider leaning out of the saddle to swing a mallet. Seven minutes of that is about as much as the horse can give before it needs to come off.

This explains the equipment list that surprises everyone. Serious players don't bring one horse. They bring a string of them, six or eight per player at the top level, and they change mounts almost every chukka, sometimes partway through one. Amanda compared it to "a pit stop," and she's right. The Museum of Polo puts it plainly: at the high-goal level, players ideally have a fresh horse for every period.

It also explains why the number of chukkas changes. Pete says "the rules literally scale to how much horsepower" a level of play can afford. Club players who own a couple of horses play shorter matches, and high-goal professionals who travel with a trailer full of ponies play the long ones. Amanda figured a string of eight horses at around $100,000 each comes to $800,000 before anyone pays for feed, grooms, or a vet. That makes the chukka count a fairly direct measure of how much money is standing in the barn.

So Can a Horse Come Back In?

Amanda asked the obvious follow-up: once a horse comes off, can it go back in? Pete guessed that "once you're gassed, you're gassed," and on the same afternoon that's mostly true. Under the Hurlingham rules, a pony can play two chukkas in one afternoon, but it needs at least one full chukka of rest in between. It can't go straight back out.

That rule explains why the strings are so big. If every pony can play at most two chukkas with a break between them, a player needs at least three horses for six chukkas, and more than that if they want a fresh horse each time and a spare for mid-chukka swaps. So the eight-horse string isn't only showing off. Most of it is what the rules and the horses' limits require.

A Word That Took the Long Way Around

Pete's favorite chukka fact is where the word came from: "Every time the commentator says chukka, they're using a 19th century British import of a word that predates the empire entirely." That holds up. British officers found the game in Manipur in northeast India in the mid-1800s and brought it home. The Cachar Club in Silchar, founded in 1859, was one of the first clubs organized by Europeans, and the Calcutta Polo Club, founded in 1862, is still playing.

The dictionaries trace chukka itself to the Hindi chakkar, meaning a circle or a round, which comes from the Sanskrit cakra, meaning wheel. That's the same chakra yoga teachers talk about. So a polo period is named after a lap, and the root word is a couple of thousand years older than the British Empire, just as Pete said. It went from India to Britain and then, as Pete put it, "we took it from Brit," when James Gordon Bennett Jr. brought the rulebook to New York in 1876.

You've Been Wearing the Word

Amanda had the best twist of the episode. Before this, the only chukka she knew was the chukka boot, the suede ankle boot with two or three pairs of eyelets. The name most likely comes from polo. The usual explanation, and the one Amanda gave, is that British soldiers in India wore a similar ankle boot, and the name followed the game. Even the reference sources say "possibly," so treat the story as likely rather than certain.

Where the boot went next is well documented. The chukka's cousin, the desert boot, debuted when Clarks introduced it at the 1949 Chicago Shoe Fair. The style became standard casual wear from the late 1940s through the 1960s. As Amanda told listeners, "You have been talking polo without knowing."

A Clock You Can't Buy More Of

The chukka is the one part of polo that money can't stretch. You can buy land, more ponies, and a higher handicap, but you can't get a horse to sprint for twelve minutes. The rulebook starts from the animal's limit and works outward, and nearly everything expensive about the sport comes from working around that one limit. That includes the strings, the trailers, and the grooms who keep eight horses fed so that one of them is fresh at the bell.

That's a good way to think about the episode's point on why polo stayed a rich person's game. The mallet and the dress code are cheap by comparison. Seven minutes is all a horse can give, so each player needs a lot of horses.

Episode 122 of Sorta Sophisticated, "The Sport So Exclusive It Made Its Own Rules," is a learn-as-we-go episode that started when Pete heard the Santa Barbara polo grounds from a wedding and realized he couldn't answer a single one of his sons' questions. It also covers the left-handed ban, which is why every polo player swings right-handed. Lefties were banned in the mid-1930s, let back in during World War II when players were scarce, and banned for good by the USPA in 1974. And it covers Bennett's move to buy a whole rail car of horses from Texas so America could start playing.
