2024 Ironman World Championship in Kona: What you need to know | Big Island Now (2025)

Are you ready for the VinFast Ironman World Championship on Oct. 26? Here’s everything you need to know about race week and race day.

This year it’s all about the men. Beginning last year, the field has been divided by gender due to the growing number of competitors. Defending Ironman World Champion Sam Laidlow of France leads an elite men’s field of 56 triathletes, including three other winners of the championship. (The women, who competed in the Kona championship last year, were in Nice, France, this year in the alternating course format).

But before race day, there are three community events.

• On Tuesday, it’s the Ironkids Keiki Dip-n-Dash at 4 p.m. at Ka’ahumanu Place. Registration is from 9 a.m. to 3 p.m. on Tuesday at the canoe landing at King Kamehameha Kona Beach Resort. The Dip-n-Dash is for kids ages 6 to 14 who have a USA Triathlon membership, and the event costs $15. Just the Dash event is for kids ages 2 to 14, with courses of 0.25 miles and 0.9 miles. USAT membership also is required, and the this event also costs $15.

• On Tuesday, it’s also the Parade of Nations, which starts at 5 p.m. The parade runs along Aliʻi Drive between the Kona Beach Resort and Hale Hālāwai.

• On Thursday, the Ironman Foundation hosts the UnderPants Run in the back parking lot of the Kona Beach Resort at 7:30 a.m. It is open to everyone, but registration is required. This event began in 1998 as a protest against wearing Speedos in inappropriate places, like stores and restaurant, but has morphed into a pre-race icebreaker and local fundraiser. Over the years, more than $360,000 has been raised for “community giveback.”

On race day, the triathlon starts at 6:25 a.m. HST, when athletes kick off the grueling 140.6-mile race in the crystal clear waters of Kailua Bay for a 2.4-mile out-and-back swim as the sun rises over Hualālai in the background.

The 112-mile bike course starts at Kailua Pier and takes athletes onto Ka‘ahumanu Highway, facing a challenging evelvation gain — of up to 5,814 feet — and potentially strong crosswinds on their climb to Hawī, but soothed by breathtaking scenes of lava fields and ocean coastlines.

At Hawī, they turn around and head back to Kona.

The triathlon culminates with a 26.2-mile run through Kona, up Palani Road and onto Queen Ka‘ahumanu Highway, where competitors will run through HOST Park at the National Energy Laboratory Hawaiʻi Authority, navigating intermittent steep spots before making their triumphant return along the highway.

Athletes will then take their victory lap down Ali‘i Drive to cross the finish line, where they started at Kailua Pier.

The seawall is the perfect spot to watch the triathletes enter the water to start the race in Kailua Bay.

Spectators then often move to line the run and bike courses on Ali‘i Drive, Palani Road and Queen Ka‘ahumanu Highway.

If you can’t make it out to watch the race in person, keep up with the athletes live on Ironman’s YouTube channel and Facebook page.

To note:

• Ka‘ahumanu Place and Kailua Pier will be closed starting at 6 a.m. midnight Oct. 24 till 3 p.m. Oct. 27.
• Ali‘i Drive from Ka‘ahumanu Place to Likana Lane will be closed starting at midnight Oct. 24 till 3 p.m. Oct. 27.
