Overview

• Ironman has confirmed that starting October 10, 2026, the men’s and women’s World Championship races will once again be held together on a single day in Kailua-Kona, Hawaii.
• The decision follows athlete feedback and research, with Ironman stating the unified format best serves the sport’s future and aligns with athlete preferences.
• The 2025 season will remain transitional, with the men’s race in Nice on September 11 and the women’s race in Hawaii on October 14 under the current rotation system.
• Since 2023, races were separated to address local concerns in Hawaii and to increase focus on women’s competition, but the split format faced significant criticism from athletes and fans.
• Nice will host the Ironman 70.3 World Championships in 2026 and 2028, as the full Ironman World Championship becomes permanently based in Kona.
