Ironman World Championship 2026: UK Start Time, How to Watch and Who to Follow

The Ironman World Championship 2026 is on Saturday 10 October in Kailua-Kona, Hawaii, and the professional men start at 5:20pm UK time, followed by the pro women at 5:30pm and the age-group race at 5:38pm. Live coverage begins at 3:30pm UK time and, according to Ironman, it streams free on its own Pro Series website and YouTube channel, with DAZN also listed as a way to watch. This year is a special one, because men and women race the full Kona course together on the same day for the first time since 2019. Below you will find a UK-time table, the British pros on the start lists, the course in plain words and a few lessons anyone training for a first triathlon can take from the biggest day in the sport.

When and where is the Ironman World Championship 2026?

Ironman lists the race for Saturday 10 October 2026 in Kailua-Kona, on the Big Island of Hawaii. It is a full-distance triathlon: a 3.8km swim, a 180.2km bike and a 42.2km marathon, which adds up to 226km.

From 2023 to 2025 the championship was split, with the men's and women's races held in different places, Kona and Nice in France. In April 2025 Ironman announced a return to a single day in Kona with men and women racing together. At the time, it said the field would grow to nearly 3,000 racers, with equal broadcast coverage for the professional men and women and more time between the start waves.

Kona is also the final stop of the 2026 Ironman Pro Series, so the season-long titles can be decided on the same day as the world titles. That adds an extra layer to the racing, because some pros will be chasing series points as well as a podium.

Edge is not affiliated with Ironman or the Ironman World Championship. The times and names in this guide come from Ironman's own published schedule, start lists and coverage page at the time of writing. All of them can change, so check the official race channels on the day.

What time does the Ironman World Championship start in the UK?

Hawaii does not change its clocks, and the UK stays on British Summer Time until the clocks go back on Sunday 25 October. That means on race day Hawaii is 11 hours behind the UK. Ironman's own race page confirms the gap: it lists the start of live coverage as 4:30am Hawaii time, which is 2:30pm UTC, or 3:30pm in the UK.

So this is an evening and overnight race for UK viewers. The swim starts in the late afternoon, the bike fills your Saturday evening and the pro winners are likely to reach the finish in the early hours of Sunday.

Start and coverage times are from Ironman's official race-day schedule and coverage pages, which say they are subject to change. The winners' finish is our rough estimate based on the fastest pros needing around eight hours, not an official figure.

How can you watch the Ironman World Championship 2026 in the UK?

Ironman says this year's coverage is live and free, running from pre-race body marking through the swim start to the finish line on Ali'i Drive. These are the global options it lists at the time of writing, which include viewers in the UK:

• Ironman's Pro Series website. Live coverage from 3:30pm UK time, free to stream according to Ironman, with replays afterwards.
• Ironman's YouTube channel. The same live broadcast, which also makes it easy to put the race on a TV.
• YouTube Multiview on a smart TV. New this year, from 5:15pm UK time you can watch up to four feeds at once, including the main broadcast and dedicated feeds for the men's and women's races. Ironman says to open YouTube on your smart TV and choose the dedicated Multiview link.
• DAZN. Ironman lists DAZN as a global option too. Whether it is included depends on your DAZN account, so check before Saturday rather than at 5pm.
• Ironman's official tracker app. It is not a video stream, but it shows live splits and leaderboards, which is handy for following one pro, or a friend in the age-group race, through the night.

Ironman's coverage page does not list a separate UK TV channel, so streaming is the main route. If you do not fancy a very late night, a good plan is to watch the swim starts and the early part of the bike live, then catch the run and the finish on replay on Sunday morning.

Which British pros should you follow at Kona 2026?

At the time of writing, Ironman's professional start lists include 11 racers representing the United Kingdom: nine in the women's race and two in the men's. Start lists can change in the final days through injury or illness, so check the official list on race morning.

• Lucy Charles-Barclay. Listed by Ironman as a former Ironman World Champion and Ironman 70.3 World Champion.
• Kat Matthews. Listed by Ironman as a two-time Ironman Pro Series champion.
• More British women on the start list: Fenella Langridge, Kate Curran, India Lee, Rhianne Hughes, Rebecca Anderbury, Daisy Davies and Rosie Wild.
• British men on the start list: Kieran Lindars and Cameron Main.

For the wider picture, Ironman's start lists and Pro Series standings at the time of writing point to a few names to watch. In the women's race, Solveig Løvseth of Norway is the reigning champion and Laura Philipp of Germany leads the Pro Series standings, with Taylor Knibb of the United States, listed as a three-time Ironman 70.3 world champion, also on the list. In the men's race, Kristian Blummenfelt of Norway leads the standings, and the start list also includes Patrick Lange of Germany, whom Ironman lists as a three-time world champion, plus fellow past winners Gustav Iden, Casper Stornes and Sam Laidlow.

A simple way to follow the British racers is to add them in the tracker app before the start, then dip into the stream whenever one of them moves up or down the leaderboard.

What is the Kona course like?

Kona is famous because it is hard in ways that have nothing to do with hills alone. Here is the course in plain words, based on Ironman's own course description:

• Swim, 3.8km. An in-water start in Kailua Bay, then an out-and-back swim in a clockwise direction. Ironman describes small swells and warm water, with an average water temperature of about 26°C.
• Bike, 180.2km. Out of Kailua-Kona along the Queen Kaahumanu Highway, known as the Queen K, to a turnaround at Hawi and back. Ironman highlights the climb towards Hawi, the exposed lava fields and strong crosswinds.
• Run, 42.2km. An out-and-back along Ali'i Drive, then up Palani Road onto the Queen K and out to the Natural Energy Laboratory, before heading back into town for the finish. Ironman calls it rolling, with some steep stretches.

Heat is the big factor. Ironman lists typical race-day air temperatures of about 24°C at the low end and around 30°C at the high end, and much of the bike and run crosses open, barren lava fields. That is why you will often see the commentators talk about pacing and cooling as much as raw speed.

What can everyday racers learn from Kona?

You do not need to qualify for Hawaii to borrow its lessons. Whether you are eyeing a pool-based sprint triathlon or a first middle distance, these habits carry over:

• Pace the bike for the run. In a long race the bike is where many people overdo it. Riding at a steady, comfortable effort and saving something for the run usually beats a heroic bike split, at any distance.
• Practise eating and drinking in training. Pros rehearse their race-day fuel. Try your snacks and drinks on long sessions so nothing is new on the day, and take extra care with fluids on hot days.
• Train the switch from bike to run. Short runs straight off the bike, often called brick sessions, help your legs get used to that heavy feeling in the first few minutes.
• Get comfortable in open water. Sighting, swimming close to others and coping with chop are skills of their own. Pool fitness is the base, and our guide to swimming for runners explains how to build it.
• Build the bike gradually. If you come from running, the bike leg is usually the biggest step up in time. Our guide to cycling for runners covers how to add rides without wrecking your running week.
• Keep strength in your week. A marathon after 180km on the bike asks a lot of your legs and core. Steady strength work through the year helps you hold good form late in a race.
