The Most Popular Triathlon Race in Every State

Published September 16, 2026 06:00AM

Whether you’re looking to tackle your very first triathlon or planning an epic swim-bike-run road trip across America, finding the right race makes all the difference. But what are the best triathlon races in each state?

That’s a tricky question – after all, criteria for the “best” triathlon of any kind is totally subjective. So to bring some method to the madness, we turned to our friends at TriFind, who shared race participation numbers to highlight the largest field sizes across the nation. In other words, triathletes themselves effectively “voted” for the best triathlon in each state with their registrations.

We excluded official Ironman-branded races, as half and full distance races aren’t hosted in every state – and besides, locally owned races are the lifeblood of triathlon. If you haven’t experienced the joy of getting a personal high-five from the race director or running down a finish chute lined with loud and rowdy local triathlon clubs, you’re missing out on one of the best parts of the sport.

Read on to discover the ultimate crowd-favorite triathlon in every corner of the country. Now start planning your race schedule for next year.

The 50 best triathlon races in each state

Alabama: Alabama Coastal Triathlon

This event isn’t just a race – it’s a full-on racecation. Sponsored by vacation rental company Brett/Robinson, the sprint- and Olympic-distance races showcase the best of Alabama’s Gulf Coast, including an open-water swim in clear waters, a flat-and-fast boulevard bike course, and a run on the boardwalk past white-sand beaches. (You’ll want to take an extra day of vacation for this one.)

Alaska: Gold Nugget Triathlon

This women’s race was founded in 2003 as a not-for-profit organization to improve the lives of women and girls through sports, and it’s since evolved into a tradition for moms, daughters, sisters, and friends to race it together. It starts with a 400-yard snake swim in a high school pool, a 12.1-mile bike ride through town to T2, then a 3.25-mile run on a wooded tank trail to finish in Pena Park Sports Complex.

Arizona: Mesa Sprint Triathlon

Open-water swimming opportunities are scarce in the desert, so it’s no surprise Arizona’s biggest race of the year takes place in a pool. The 400-meter serpentine swim, looping 12-mile bike, and 5K run attract beginners and veterans alike, and all proceeds go to the community’s parks & rec programs, fueling the next generation of triathletes.

Arkansas: DeGray Lake Tri Fest

Nestled among the Ouachita Mountains near Hot Springs is DeGray Lake, an exceptionally clean and clear reservoir on the Caddo River. This multisport festival hosts both an Olympic (1.5K swim, 40K bike, 10K run) and sprint (500-yard swim, 13.5-mile bike, 5K run) triathlon, plus a sprint duathlon, aquabike, and open-water swim. It offers a “101 workshop” the day before the race, where a USAT official and veteran triathletes answer newbie questions.

California: Escape from Alcatraz Triathlon

This iconic bucket-list race starts with a ferry ride that takes you near Alcatraz Island, where you plunge into the San Francisco Bay to begin the cold and choppy 1.5-mile swim to shore. Followed by a half-mile transition to the hilly and scenic 18-mile bike, you’ll never forget the varied terrain of the run section taking you across a bridge, through sand, and up a sand ladder.

Colorado: Boulder Sunset Triathlon

Contrary to its name, the Boulder Sunset Triathlon is actually a morning race offering sprint and Olympic courses. This race is great for those starting out, thanks to predictable weather, simple terrain, and distinctive colored swim caps to make it easy for volunteers to spot and support those not yet comfortable with open-water swimming.

Connecticut: Race4Chase Connecticut

This race, created to honor young triathlete and Sandy Hook victim Chase Kowalski, is the culmination of a six-week summer triathlon training program for children ages 6-12. Though the race isn’t open to the public, adult triathletes enthusiastically sign up to volunteer and welcome the new class of swim-bike-run enthusiasts. Think Ironman’s magic hour, but cuter.

Delaware: Lums Pond Triathlon

A lake swim, flat-and-fast bike, and shaded run make this race a go-to for triathletes in the northeastern United States, who make a weekend of it by camping on-site. Celebrate your finish by taking the kids to the in-park zipline and aerial ropes course, or raising a glass at nearby Stewart’s Brewing Company.

Florida: St. Anthony’s Triathlon

Established in 1984, this Gulf Coast race is one of the country’s oldest and largest Olympic-distance triathlons. The early-season race kicks off the season for pros and age-groupers alike, and why wouldn’t it? After all, there’s nothing like a swim in Tampa Bay and a bike through sunny St. Petersburg to shake off the winter and arrive fully in race season.

Georgia: Tugaloo Triathlon

Taking place at Tugaloo State Park on Lake Hartwell in Georgia, this race is worth a weekend trip to camp or stay near the sprawling 56,000-acre lake, which features plenty of non-triathlon activities for the entire family. The sprint and Olympic distance options, as well as relays and an aquabike, all arrive at a finish-line party full of food, live music, and plenty of fun.

Hawaii: Lavaman Triathlon

Forget Kona – the “real” Hawaii race is Lavaman, according to locals. On the Big Island of Hawaii, this Olympic triathlon makes a perfect tropical spring break racecation at the Waikoloa Beach Resort. The swim is warm (and non-wetsuit, making one less thing to pack), the bike course takes you through sprawling black lava fields, and the run is a fast and fun tour through the grounds of the resort.

Idaho: Burley Lions Spudman Triathlon

This family-friendly event, which celebrated its 40th anniversary last year, is so popular with triathletes that it uses a lottery system for entries. The Olympic- and sprint-distance course features a downriver swim, a mostly flat bike course, and a run on country roads and canal banks. The nonprofit event serves as the primary fundraiser for the Burley Lions Club, which provides free eyeglasses and eye exams, and supports schools, sports teams, and shelters.

Illinois: Chicago Triathlon

The biggest triathlon in the U.S. (and hoping to eventually become the biggest triathlon in the world) saw almost 9,000 athletes compete in 2026, according to Supertri. Taking place in the heart of downtown Chicago, the race starts in Lake Michigan, takes athletes through downtown on the bike, and finishes with a run winding around the city and along the waterfront. With a host of distances to choose from, relays, a free first-timer program, and even a Divvy bike race that we tried ourselves, where athletes can take part without even having to bring their own bike, there’s something for everyone.

Indiana: Indianapolis Sprint Triathlon

The biggest race in Indiana is a tie between both races in the Indianapolis Sprint Triathlon Sprint Series. The 500-meter swim, 10-mile bike, and three-mile run, repeated twice in the season, is a great way for athletes to test their fitness and progress in a race environment. Use their referral program to save on costs: for every two people you recruit, the race will refund $5 of your entry fee.

Iowa: Tri Clear Lake

Starting and finishing in downtown Clear Lake, this beginner-friendly race offers both sprint and Olympic distances. The race starts from City Beach with a scenic lake swim, then a flat, fast bike course past scenic prairies and windmills. The race ends with a run past the historic Lady of the Lake riverboat before a lakeside finish in City Park.

Kansas: Shawnee Mission Triathlon

The oldest triathlon in the Kansas City area brings something for everyone, from first-timers to advanced athletes to clubs looking to compete. There’s a kids race, distances ranging from supersprint to Olympic, and even a unique “long-course” distance that sits between a sprint and Olympic. With everything taking place around Shawnee Mission Park Lake, spectators and family members will have plenty of chances to see their athletes – especially with the Olympic-distance bike requiring six laps.

Kentucky: Tri Louisville

Race through the heart of Louisville on this flat and fast, urban short-course triathlon. Offering both a sprint and Olympic distance, plus a duathlon, Tri Louisville starts with a point-to-point swim in the Ohio River followed by a fully closed bike course through downtown Louisville along Waterfront Park. The run takes athletes on Riverwalk paths with crowds of cheering spectators pushing them to the finish in Waterfront Park.

Louisiana: Louisiana Triathlon

Founded in 1989, this race has stood the test of time precisely because it refuses to get stale: each year, the race is rebranded with a distinct local theme, such as “Laissez le Bon Temps Rouler!” or “Red, White, and Bayou,” and pairs with local businesses and musicians to create the ultimate party atmosphere.

Maine: Tri For a Cure

This women’s-only triathlon is the largest race in the state, with more than 1,200 women turning out each year to raise money for the Maine Cancer Foundation, one stroke, pedal, and stride at a time. It’s working – since its inception in 2008, the race has raised more than $2.3 million, all of which goes to the cause, thanks to sponsors who cover the operational costs of the race.

Maryland: Watermans Triathlon

A protected harbor swim, a smooth rural bike course, and a flat coastal run in the historic, laid-back fishing town of Rock Hall, Maryland – it’s no wonder triathletes flock to this race festival every year. Though most tackle a sprint or Olympic-distance race, the race weekend also boasts a rare half-iron race that isn’t a branded Ironman 70.3. Sign up for both a Saturday and Sunday race to get a 20% discount (and complimentary bragging rights).

Massachusetts: Cohasset Triathlon

The race is super-scenic, with waterfront views on the bike and run, but that’s not what keeps 1,000-plus triathletes coming back every year. The town turns out for this community-centric race that doubles as a street fair, with live music and crowds lining the course. Keep your transitions snappy – there’s an award for the fastest combined T1 and T2 time – and head to Split Rock Beer Garden after the race for an unforgettable post-race party.

Michigan: Grand Rapids Triathlon

Just east of Grand Rapids, Michigan, is Ada, which hosts this popular flat-and-fast triathlon on forested country roads. The race offers a super sprint, sprint, Olympic, and half-iron option for those looking to take in more of the scenery. With cool temperatures and a friendly host community, it’s no surprise triathletes flock to this June race.

Minnesota: Maple Grove Triathlon

Experience countryside charm at this small-town Minnesotan race across its international, sprint, and super-sprint distance triathlons. Athletes first swim in the pristine Weaver Lake before hopping on their bikes for a tour of the scenic nearby towns, crossing into Plymouth, Corcoran, and Hanover city limits with locals cheering on athletes from their front porch steps. The run goes around the lake and through the surrounding neighborhoods before a finish in Weaver Lake Park.

Mississippi: Bay St. Louis Triathlon

Feeling the need for speed? Check out this super-fast, super-straight boulevard bike course, where you’ll only find one turn for 15 miles. The rest of the way, you can tuck into your aerobars and shoot for a PR (vroom-vroom noises optional, but highly encouraged). Your reward? An epic beachside after-party, where beginners and veterans swap tales of speed and commiserate on future race plans.

Missouri: Kansas City Triathlon

An early-season wetsuit-legal swim, a fully-closed-course racing experience, and spectator-friendly looped layout make this race a must-do for Missouri triathletes. Whether you’re tackling the sprint- or Olympic-distance triathlons, doing the duathlon, or partnering up with friends for the Olympic relay, there’s something for everyone. New to tri? Check out their pre-race open water swim and race-practice clinics, which are tailored for beginners.

Montana: Montana Women’s Triathlon

Celebrating the strength of women in sport, the Montana Women’s Triathlon is an event filled with inspiring stories. This sprint triathlon is meant to be a low-stakes, friendly competition among friends, family, and the community instead of a high-pressure, elite race. Taking you through the streets of Helena, Montana, the course is designed to be cheer-friendly so spectators can motivate you at every turn.

Nebraska: Omaha Triathlon at the “C”

As the host of the 2025 USA Triathlon Multisport National Championships, this large venue is clearly primed for a whole host of triathlon and multisport events. Choose from a variety of races and distances, including a duathlon and a rare aquathlon, where athletes can swim and run and avoid the hassle of a bike altogether. If you do choose to bike, expect a rolling, scenic course before the flat run keeps you close to the shoreline for lake views along the way.

Nevada: Slide-Dash-Splash Water Park Triathlon

While it’s not a traditional triathlon, the Water Park Triathlon is a fun multisport experience that works for a range of ages and fitness levels. At the Wild Island Water Park just outside of Reno, you slide down the “zulu slide,” run or walk a 1-mile loop through the park, then finish by either swimming or jogging the lazy river. The goal is to complete the most laps of the course in the allotted time.

New Hampshire: White Mountains Triathlon

Set in the dramatic scenery of the White Mountain National Forest, athletes use this race weekend – which features sprint, Olympic, and half-iron options – as a way to explore the great outdoors through swim, bike, and run. Bring your granny gear for the King of the Mountain challenge, a mid-race award that yields cash, polka-dot jerseys, and ultimate bragging rights.

New Jersey: Challenge New Jersey State Triathlon

Another race hosted by Supertri, this is one of the largest in the nation and has been around for 20 years, typically selling out with more than 3,500 athletes each year. Part of what attracts so many athletes is the flat and fast course. And if you go in search of that PR and achieve it, you can celebrate afterward at the post-race festival, which features food, drinks, and live music.

New Mexico: Lobo Triathlon Sprint

You’re not upside down: this iconic spring race turns the standard swim-bike-run on its head by offering a reverse triathlon format, with a 5K run and 12.5-mile bike through the interior of the University of New Mexico campus followed by a 400-meter indoor pool swim in the school’s Seidler Natatorium. The race is organized by students in the UNM Health, Exercise, and Sports Sciences department – the closest thing to majoring in triathlon as you can get at a university.

New York: Alpha Win, Lake George Triathlon

This race kicks off from the golden sands of Lake George’s Million Dollar Beach, then heads into an Adirondack tour of mountain, forest, and lakeside views. Though the hilly bike course may not be the place you set a PR, it’s the perfect place for a fun day with hundreds of your closest swim-bike-run friends.

North Carolina: YMCA Wrightsville Beach Triathlon

Originally founded as the Pepsi Triathlon in 1979, this sprint-distance race has become one of the most popular triathlons on the East Coast. Though the 1,200-meter swim may seem long for a sprint (and it is!), it’s a current-aided point-to-point swim – the closest thing to “swimming downhill” you’ll see in multisport. Throw in a flat 11-mile bike course and one-loop 5K run around Wrightsville Beach Park, and you’ve got a fine recipe for a personal best time.

North Dakota: Bisman Triathlon

Midwest hospitality shines at this all-comers race, which goes out of its way to make athletes feel welcomed. Athletes love the clear communication from the RD, “Tri 101” clinics for beginners to master the fundamentals, and the encouraging community feel of transition. It’s no surprise that many first-timers become return visitors, doling out high-fives to the newbies on the course.

Ohio: Tri CLE Rock Roll Run

You don’t have to take our word for it: this race festival of triathlon, duathlon, and aquathlon in varying distances is regularly hyped by our readers as one of the best locally-owned triathlons in the nation, and has won USA Today’s Reader’s Choice Award for best triathlon three years running. The event features a Lake Erie swim, a traffic-free bike course on the Memorial Shoreway, a scenic lakeside run, and one epic post-race party.

Oklahoma: TORC Triathlon

Want to swim in an LA28 Olympic venue? Head to Oklahoma (yes, you read that right). The man-made river rapids in the heart of Oklahoma City will serve as the Olympic venue for canoe slalom and kayak cross for the upcoming Games, but it’s already known to local triathletes as the site of their favorite local race. Sign up for the sprint, duathlon, or aquabike race; or change things up with the adventure triathlon, which swaps out the swim for a 500-meter kayak or paddleboard.

Oregon: Best in the West Triathlon Festival

The result of a college project and a love story brought Oregon’s greatest triathlon. The super sprint to the half-iron course has everything you can expect in a scenic race through the Cascades, but the post-race festival raises the standard. Its Old West theme is accompanied by cowboy hats, a saloon, BBQ, handmade horseshoe trophies, and – of course – a shotgun start.

Pennsylvania: North Penn IronKnights Kids Triathlon

One of the largest one-day youth triathlon races in the country is this annual event for North Penn School District elementary school students, which draws close to 2,000 participants for a field day of swim-bike-run around the school’s campus. In the lead-up, the school hosts four practice swims and an orientation evening to help students and parents prepare for the big day.

Rhode Island: Block Island Triathlon

Off the coast of Rhode Island is the beachy getaway destination of Block Island. Athletes may stay on Block Island or ride the race-chartered ferry race morning to get to the island. This sprint tri is intimate, with entries capped at 500 registrants in 2026, and always sells out. If you get in, you’re guaranteed a small field with a personal, uncrowded atmosphere and a New England buffet of postcard beach views.

South Carolina: Strong Kids Junior Triathlon

The biggest race in South Carolina boasts the tiniest triathletes. Ages 4-8 tackle the “Kinder” distance, a 25-yard swim, one-mile bike, and quarter-mile run, while ages 6-15 race the “Junior” distance, a 100-yard swim, four-mile bike, and one-mile run. A looped course means young athletes get lots of cheers (and photo opportunities for proud parents), and the finish-line medals are some of the cutest in the sport.

South Dakota: Wildlife Loop Triathlon

South Dakota’s only half-distance triathlon takes athletes right through the heart of Custer State Park, where racers can see roaming wildlife like bison and elk along the course. Sprint and Olympic distance options are equally scenic, looping around Stockade Lake in a format that both athletes and spectators enjoy.

Tennessee: Chattanooga Waterfront Triathlon

This long-standing (more than 40 years!) triathlon gives athletes a PR-worthy, urban course in downtown Chattanooga. It starts with a downstream swim in the Tennessee River, then a bike and run along the riverfront paths and Riverwalk. The race will be moving to a new, yet-to-be-announced venue in 2027, but expect the vibrant crowds and Southern hospitality to remain the same as ever.

Texas: Houston Kids Triathlon

Everything’s bigger in Texas, and this race isn’t just the biggest in the state – with 1,600 young athletes taking part in this waterpark-hosted tri, it’s also one of the largest youth triathlons in the world. The race weekend is strictly a youth event for ages 17 and under – which makes the grown-ups green with envy, because of course we want a swim course in a lazy river, too.

Utah: TriUtah Brineman Triathlon

This unique course, which offers distances from sprint to half-iron, starts with a swim in a private, residential ski lake community with views of the Wasatch Range. Athletes then ride their bikes across a bridge to Antelope Island, a state park within the Great Salt Lake (watch for bison and antelope!). The run starts from Still Water Lake and finishes at Jensen Nature Park.

Vermont: Vermont Sun Triathlon

This June race is the crown jewel of the four-race Vermont Sun series, which features a sprint and Olympic-distance triathlon, running festival (5K through half marathon) and a paddle-bike-run race called the Branbury Classic. Though à la carte registration is an option, many build their season around the entire series, meaning the strangers you see at the first race will be your best adventure buddies by the time you cross the finish line of number four.

Virginia: Kinetic Triathlon Festival

Athletes and spectators alike rave about this race weekend, which features a rare locally-owned half-distance race along with the more-popular sprint and Olympic distances. Features like stadium seating overlooking transition and the finish line, a closed bike course contained entirely within a state park, and plenty of kid-friendly activities make this a full family fun weekend.

Washington: Seafair Triathlon

The premier tri of the Pacific Northwest is hosted by Seattle. Race-day weather is very reliable and pleasant compared to other triathlons in July, with the sprint and super-sprint wrapping up within a cool-temperature window before any afternoon heat waves kick in. The bike course is already popular among local cyclists, with views of Lake Washington and the Bellevue skyline across the water. A kids short course and long course are also on offer.

West Virginia: Scenic Mountain Triathlon

Another race Supertri recently acquired, this is one of the largest in the nation and has been around for 20 years, typically selling out with more than 3,500 athletes each year. Part of what attracts so many athletes is its flat, fast course, and if you manage to achieve a PR because of that, you can celebrate afterward at the post-race festival, complete with food, drinks, and live music.

Wisconsin: Door County Triathlon

Set in a popular Midwestern tourist destination known as the “Cape Cod of the Midwest,” the Door County Triathlon gives athletes a stunning race setting amid sandy shores and majestic bluffs. While the race no longer offers a half-iron, athletes can do the “double door” by completing the sprint Saturday and the Olympic on Sunday.

Wyoming: Lander Reverse Triathlon

If you’re looking for something totally out of the ordinary on this list, head to Lander, Wyoming, where their race – a 5K run, 20.5K bike, and 600-yard swim – yes, in that order – will have you rethinking how to race a triathlon. You might jump to the conclusion that swimming last isn’t the safest option, but this swim takes place in a pool, keeping athletes in a controlled environment after pushing through the scenic bike and run at the foothills of the Wind River Range.
