When Is Ironman Kona 2025. Join us on october 26, 2025. Try yourself in one of the world's toughest races and prove that you really are made of steel.

Then in 2025, the two groups will flip locations, with women racing in nice on september 24 and men racing. The bike course is the most obvious difference between ironman world championship courses in nice and kona.
