Quick answer: The 2026 Ironman World Championship is in Kailua-Kona on Saturday, October 10, and for the first time since 2019 the professional men and women race on the same day. If you are visiting that week, expect a busy, happy town, fuller restaurants, higher rates and road closures on race day along Aliʻi Drive and the Queen Kaʻahumanu Highway. Stay somewhere you can get out of town easily, like Kealakekua, or right in the middle of it, like Casa Aloha in Kailua-Kona, and plan race day around the course.
Once a year our little coffee town turns into the center of the triathlon world. For most of the year Kailua-Kona is a sleepy place with a seawall, a pier and a handful of good restaurants. Ironman week, it fills with some of the fittest people on the planet, their families, their coaches and their very expensive bicycles. It is one of the best weeks of the year to be here if you know what you are walking into, and one of the more frustrating ones if you do not.
Here is what we tell guests who find out their dates overlap with the race.
When is Ironman in Kona in 2026?
Race day is Saturday, October 10, 2026. The swim starts from the Kailua Pier in Kailua Bay early in the morning, with the professionals off at around 6:25am. Athletes then ride 112 miles out along the Queen Kaʻahumanu Highway toward the Kohala Coast and back, and finish with a marathon that runs through town and out onto the highway before coming home to the finish line on Aliʻi Drive.
This year matters more than usual. For the last few years the men and women raced on separate days, some of them in Nice, France. In 2026 everyone is back in Kona on the same day, which means one very big race day rather than two smaller ones, and a town that is fuller than it has been in a while.
The race itself is one day, but Ironman is really a week or more. Athletes arrive early to get used to the heat and the wind, and you will see them everywhere, swimming laps off the pier at sunrise and riding the highway in long lines all week.
What Ironman week is actually like in Kailua-Kona
The town is buzzing. Aliʻi Drive is full of people in compression socks drinking very large coffees. There is an expo, flags from dozens of countries, and a real sense that something big is about to happen. If you like people watching, it is hard to beat.
Restaurants are busier. The places in town that are easy to walk into the rest of the year have a wait, especially around breakfast and early dinner. Make reservations where you can, and eat a little earlier or later than the crowd. Our Kona Town eat and drink page and our guide to where to eat breakfast in Kona have the places worth planning around.
The morning swim is a show. Head down to the pier around sunrise any day that week and you will see hundreds of athletes swimming out into Kailua Bay. It is free, it is beautiful and it is one of our favorite things about the week.
The roads are shared with bikes. Expect cyclists on the Queen Kaʻahumanu Highway all week, often in groups. Give them space, pass carefully and be patient. They are training for the hardest day of their year.
Prices go up. Hotels, rental cars and vacation rentals in and around Kailua-Kona book up and cost more during race week. If your dates are flexible, the week after is noticeably calmer. If they are not, book as early as you can. Our guide to how far ahead to book a Big Island vacation rental covers race week along with the other busy times.
Race day: what to know if you are not racing
Saturday is the day that needs a plan.
Roads close. Aliʻi Drive and large parts of downtown Kailua-Kona close to traffic, and the Queen Kaʻahumanu Highway is the bike course, so it is restricted for much of the day. Check the official Ironman and Hawaii County closure notices the week of the race for exact times, because they can change.
Getting to or from the airport takes longer. Kona International Airport sits right on the Queen Kaʻahumanu Highway. If you are flying in or out on October 10, leave much more time than you think you need, or better yet, avoid race day for travel altogether. Our guide to flying into Kona has the usual advice, and on race day you should double it.
Parking in town is very hard. People start staking out spots before 5am. If you want to watch the swim start, go early, or stay somewhere you can walk from.
The finish line at night is the best part. The professionals come down Aliʻi Drive in the afternoon, but the magic happens after dark, as age groupers who have been out there all day come home to a crowd that cheers every single one of them. Stay until close to midnight if you can. People who have never cared about triathlon tell us it is one of the most moving things they have seen on the island.
If you just want a normal vacation that week
You can absolutely have one. The race is in and around Kailua-Kona and on the highway north of town. South of town, life goes on pretty much as usual.
Race day is a great day to head south. Kealakekua Bay and Puʻuhonua o Hōnaunau are both well away from the course, and so are the coffee farms. A coffee farm tour is a lovely way to spend a morning while town is closed. At Kona Coffee & Tea, ask for Brad, he is one of their guides and he is great. Or make it the day for the long drive to Hawaiʻi Volcanoes National Park, which heads south and east, away from the race.
For dinner, the places in South Kona are a nice break from the crowds in town. Our South Kona eat and drink page has the ones we send guests to.
Where to stay during Ironman week
There are two good answers, and they are opposites.
Right in the middle of it. If you are racing, supporting someone who is, or you just want to soak up the atmosphere, being able to walk everywhere is worth a lot that week. Casa Aloha is our one bedroom in Kailua-Kona, close to Aliʻi Drive and walkable to town, with a pool to cool off in after a long day of cheering. You can leave the car parked on race day and walk to the course.
Up the hill and out of it. If you want the island without the crowds, Kealakekua is about twenty minutes south of town and feels a world away. Casa Grateful is our one bedroom there, with a covered lanai and an ocean view, a good fit for a couple. Casa Gratitude is our three bedroom in Kealakekua, with an open kitchen and living room under a vaulted cedar ceiling, which works well for a family or a support crew traveling together. You can drive into town for the finish line at night and come home to quiet.
If you are still deciding between the two areas, the best area to stay in Kona and Kealakekua lodging versus Kona hotels lay out the tradeoffs.
