Kona men’s field set: Norwegian trio headlines Oct 10 world title fight
IRONMAN has published the professional men’s start list for the 2026 World Championship in Kailua-Kona — more than 55 pros chasing the sport’s biggest one-day prize on Saturday, 10 October.
The Norwegian hype train returns
Stornes arrives as defending world champion after Nice and a 2026 win at IRONMAN Frankfurt. Iden was runner-up last year. Blummenfelt, the 2025 Pro Series champion, has stacked wins including Texas and sits among the form horses again.
Five former world champions are on the sheet when Lange and Laidlow are counted with the Norwegian trio — depth that Slowtwitch and IRONMAN both flagged as unusually stacked even by Kona standards.
Course and stakes
The championship still follows the classic test: 3.8 km swim in Kailua Bay, 180 km bike through the lava fields and the Hawi turn, 42.2 km run to Aliʻi Drive. Live coverage is scheduled free on IRONMAN Pro Series channels and YouTube.
Alongside the title, pros share a $375,000 professional prize purse and the last major Pro Series points haul of 2026.

Why age-groupers should care
Start lists are not just fan service. They telegraph bike depth, run standards, and who will drag the front group into the wind on the Queen K — information that shapes how age-group athletes watch pacing and nutrition on race week.
With five weeks still to go, expect late withdrawals and final form tweaks. For now, the published field already answers the September question: Kona 2026 is not a transitional championship. It is a collision of the Nice podium, returning champions, and a Pro Series title still alive on paper.
