Back in 1986, Bay to Breakers set the Guinness World Record for the largest footrace, with 110,000 registered participants. If you want to understand what type of sports event would summon so many athletes, you need to picture a unique blend of a race and an all-out costume parade.

This 7.5-mile course stretches from the San Francisco Bay (at Howard Street) to the Pacific Ocean. Held every third Sunday of May, the event is a local party where people wear elaborate costumes—think cartoon characters, colorful animals, and even synchronized group outfits. Bay to Breakers began in 1912 as a way to boost morale in San Francisco after the devastation of the 1906 earthquake.

You’d be wrong to think that the San Fermin Festival is only held in Pamplona, Spain. In 2007, New Orleans created its own version of the "Running of the Bulls." Here in the U.S., participants dress in all-white clothing with red accessories, as per tradition. But they don’t run from bulls: they run from roller derby skaters wearing horned helmets, wielding plastic bats, and chasing them around the streets.

Held in the summer to coincide with Pamplona's festival dates, this event is accompanied by food, drinks, live music, and a lively atmosphere that blends Spanish and New Orleans styles.

Did you know that you can sail inside a pumpkin? This is standard procedure at Goffstown Pumpkin Regatta, held every autumn in New Hampshire. In the year 2000, local growers envisioned an event that would turn oversized pumpkins—some weighing as much as 1,000 pounds—into something fun and unusual.

Their challenge? Hollowing out massive pumpkins to turn them into boats, to then paddle them in a regatta down the Piscataquog River. Over the years, more and more contestants signed up to participate with flamboyant pumpkin designs and matching costumes. Of course, the event also features a pumpkin weigh-off, craft and food vendors, as well as live music and games.

Twinsburg, Ohio, decided many decades ago that it was the perfect location to hold a yearly celebration of twin siblings. After all, the town was named after identical twin brothers who owned most of the land in the 1800s. Over the years, the festival has grown to become the world’s largest annual gathering of twins, triplets, and other multiples.

Traditionally, all participating twins show up dressed either identically or mismatchedly. Some of them even showcase their talents, ranging from music to comedy. Among food stalls, carnival rides, and live music, there is also a "Research" spot. There, scientists and researchers attend to study willing twins for insights into genetics, biometric data, and their health conditions.

Houston’s Art Car Parade began in the 1980s as a way to promote unconventional creativity and art. Back then, only 40 vehicles participated, but today the festival has become one of the most colorful art car parades in the world.

Participants transform their cars, bikes, and other vehicles into mobile artworks for this yearly parade held every April. Cars with the most outrageous designs—styled to look like dragons, unicorns, fruits, or even structured to appear to be stacked on top of one another—have been featured in past celebrations. Nowadays, the parade attracts over 250 art cars from across the U.S., as well as an audience of 250,000 lined up to watch.

A beach invaded by corgis sounds like a heavenly sight for dog lovers. Every year at Huntington Beach, California, this event gathers corgi enthusiasts and their furry friends to celebrate their love for the breed.

Sometimes the dogs wear costumes, and contests are run with categories like "Best Themed Outfit" and "Cutest Corgi." Short races are also organized, though owners know their corgi's legs aren't built for speed, so the event is held in good humor to watch the corgis happily walk around. Mr. Pickles the Corgi, the mascot of the event, has become an internet sensation. Of course, the beach day features merchandise stands with corgi-themed products for dogs and their humans to take home.

Organized on the Saturday closest to the summer solstice in Seattle’s Fremont neighborhood, this celebration has become a symbol of creativity, self-expression, and community. It was conceived in the late ‘80s to counter corporate-sponsored parades, which locals found cold and generalistic. They decided to combat it by organizing a parade that would showcase warmth and individuality.

The parade prohibits motorized vehicles, written words, and commercial logos. Only handmade arts and crafts are allowed. Puppets, dance troupes, musicians, and giant kinetic sculptures are often seen parading the streets of Freemont under the sun. The event usually wraps up at sunset with picnics and music at Gas Works Park.

You read that correctly. There’s an underwater music festival held every summer at Looe Key Reef, off the coast of the Florida Keys. The event was designed to combine two things the region is known for: the preservation of marine life and laid-back music.

Don’t worry, the music is not played directly underwater. Musicians pre-record the performances and these are transmitted through waterproof speakers placed along the reef. The playlist also often includes water-themed hits like "Yellow Submarine" by The Beatles and "Fins" by Jimmy Buffett. Many participants show up to dive in wearing fanciful costumes, like mermaids or sea creatures.

Some of the most famous festivals across the country are Renaissance fairs that draw visitors into an immersive celebration of medieval and fantasy culture. The largest of these is the Texas Renaissance Fair, which takes place on a former strip-mining site near Houston.

Hundreds of thousands of fans flock to this festival. It features a 55-acre village with cobblestone streets, themed buildings, and costumed performers. In it, fans can wander through medieval taverns, blacksmith shops, and artisan booths. Different shows add to the atmosphere, including jousting tournaments and falconry demonstrations. The event is held over several weekends, each with a different theme, such as Oktoberfest, Pirate Adventure, or Celtic Christmas.

We conclude with the only festival in the country where you could ask for garlic ice cream. Until 2019, every July in Gilroy, California, garlic growers and lovers would gather for the Gilroy Garlic Festival, which had become a world-renowned event. Sadly, after 2020, the event was discontinued.

Of course, you could approach the food stands and ask for your typical garlic fries or garlic bread. But there was much more to do. You could attend cooking demonstrations, and garlic-themed contests (like the garlic-braiding competition), and enjoy live music across several stages. There was also a Miss Gilroy Garlic Queen pageant, where contestants were judged not only on traditional pageant criteria but also on their knowledge of garlic.
