In 2015, Joy Vanderwal was sitting at a house on Akoni Pule Highway when the eventual race leader rode past her front door on his way to becoming an Ironman. She had lived on and off in Hawi since 2006, and the house happened to sit directly on the bike course, close enough that she watched Tim O'Donnell round the turnaround before most of the field had even reached the halfway point. She wasn't glued to a broadcast. She just walked outside when the race came by, the way most of the town does, because the world's biggest triathlon rolls through Hawi roughly once a year and staying inside would mean missing it.
That's the version of Ironman Saturday most people who live along the highway already know. What's different this year is the size of what's coming through.
Why the Turnaround Sits in Hawi and Not Somewhere Easier
The Ironman World Championship bike leg runs 112 miles round trip, out of Kailua-Kona along Queen Kaʻahumanu Highway, then north on Akoni Pule Highway to a turnaround in Hawi before doubling back the same way. Course analysts who track the route mile by mile put the turnaround itself at roughly mile 52.7, meaning riders have already covered more than half their bike leg by the time they reach town, and still have the same distance to grind back through before they're even off the bike.
The corner that gets them there has a reputation. Riders drop off Queen K down what locals and race guides both call Kawaihae Hill, then sweep onto Akoni Pule Highway toward Hawi, a turn that course guides flag as one of the roughest stretches on the entire route because of pitted, cracked pavement right where riders need to be steering wide and shifting for a steep pitch. From that corner to the Hawi turnaround is a little short of 20 miles of rolling hills, a stretch professional racers describe as the longest 20 miles of the day. It's also where weather can flip entirely, since the turnaround sits far enough north that conditions in Hawi on race day can look nothing like the high-80s heat baking Kailua-Kona at the same hour.
None of that is new information to anyone who has watched the race come through before. What is new is who's riding it.
The Race Nobody in Hawi Has Seen at Full Size Since 2019
For most of the past several years, the Ironman World Championship has split its professional men's and women's fields across separate days or separate host cities, a format shaped by pandemic-era logistics that never fully unwound. That meant whoever was watching from a porch on Akoni Pule Highway was only ever seeing half the picture on any given Saturday.
October 10, 2026 changes that. Ironman's own format announcement confirms this is the first time since 2019 that professional men and women will race together in Kona on the same day, with a combined field of nearly 3,000 athletes moving through the course at once. For a town whose entire relationship with the race is built on watching it pass by, that's the difference between a spread-out trickle of cyclists over several hours and a fuller, more continuous parade, pros and age-groupers alike, working through the same short stretch of highway on the same afternoon.
| Format | Most recent years | What rolls through Hawi |
|---|---|---|
| Split by gender or by host city | 2020 through 2025 | Roughly half the elite field on any single Saturday |
| Combined single-day race | Last seen in 2019, returning in 2026 | Full professional and age-group field on one Saturday |
If the 2015 turnaround Vanderwal watched felt like enough of an event to walk outside for, this year's version is the biggest single-day version of that same event the town has hosted in seven years.
What Actually Closes on Akoni Pule Highway, and What Doesn't
The corridor already gets a preview each year when the shorter Ironman 70.3 race uses the same stretch of Queen Kaʻahumanu Highway heading toward Kohala. Big Island Now's coverage of the June 2026 race advised motorists to expect slower traffic and to plan around the closure as riders climbed toward Hāwī, the same pattern that repeats at a larger scale in October.
For the World Championship itself, the practical shape of the day is straightforward even without a published minute-by-minute schedule: Akoni Pule Highway carries the race for the bulk of the afternoon, and Mamalahoa Highway, Route 190, remains the standing alternate for anyone who needs to move north or south without crossing the course. If your errand list for October 10 includes anything on the highway itself, the plan isn't complicated, it's just about timing it around the corridor rather than through it.
The Businesses Sitting Right on the Route
A handful of Hawi's most familiar storefronts sit close enough to Akoni Pule Highway that the race effectively passes their front steps. Bamboo Restaurant, open for lunch Tuesday through Sunday and known for its Sunday brunch, occupies a building that started as a hotel a century ago and has run as Bamboo since 1993. Saturday is a normal open day there, which means race day lunch service happens with a bike race rolling past the same sidewalk as the tables. A short walk in either direction turns up Kohala Coffee Mill, Tropical Dreams Ice Cream, the small cash-only counter at Mi Ranchito, and Street Peek Thai, all sitting inside the same few blocks the turnaround occupies.
None of these businesses close for the race. What changes is the texture of the afternoon around them, a steadier flow of cyclists, support vehicles, and the loose cluster of locals who wander out to watch rather than plan a whole day around it. That's the same low-key relationship to the event that's defined Hawi's side of the Ironman for years, just with a bigger field moving through it this time.
Hawi has never treated race day as a ticketed spectacle the way Kailua-Kona does around its finish line on Aliʻi Drive. There's no grandstand here, no expo, nothing sold specifically because the race is in town. What there is, according to people who've lived along the course for years, is a town that steps outside when it hears the race is close, watches for a while, and goes back to its Saturday. This year that Saturday just happens to carry twice the field it has in years past.
