A Quick Recap: Recent History of the Competition

To understand why 2026 is such a landmark year for the triathlon, it helps to look at its recent history.

  • Pre-2020: Both the women’s and men’s World Championship races were held together on a single day in Kona
  • 2022: The events were split into two days, proving logistically difficult for the athletes and local community
  • 2023-2025: To ease the impact, the men’s and women’s races were split and alternated annually between Nice, France, and Kona, Hawaii

The Single-Day Unified Race is Back in Kailua-Kona for 2026

Following feedback from the community, the split-city format for the competition has officially ended. Starting October 10, 2026, Ironman in Kona returns to its previous iteration, holding both the women’s and men’s races on the same day in Kailua-Kona.

Key highlights for 2026:

  • One Unified Event: Men and women will once again race together on the iconic Big Island course
  • Increased Coverage: New staggered start times and broadcast innovations will ensure global visibility for both competitions

Looking Ahead to 2027 and Beyond

Luckily, the return to a single-day race in Kona isn’t a temporary measure. It’s instead the new long-term format for the Ironman World Championship moving forward. You can expect the race to return in October 2027 and in future years to come.
