What is the Ironman 70.3 World Championship?
The Ironman 70.3 World Championship is the world title race of half-distance triathlon — 1.9 km swim, 90 km bike, 21.1 km run — the championship of the world's most-raced long-course format.[1] [2]
Who organizes it and how do athletes qualify?
The IRONMAN Group owns the championship; entry — professional and age-group — is by qualifying slots earned at Ironman 70.3 races worldwide, the same documented meritocracy as Kona's.[1]
When and where is it held?
Annually, on a deliberate global rotation unlike Kona's fixed home: recent hosts run from Taupō, New Zealand (2024) to Marbella, Spain (2025), with a two-day women's/men's format since 2022.[2] [3]
| Season | Pool / Format | Host cities |

| 2025 | Two days | Marbella (ESP), 8–9 Nov |
| 2024 | Two days | Taupō (NZL) |
| 2023 | Two days | Lahti (FIN) |

| 2018 | Two days | Nelson Mandela Bay (RSA) — first African edition |
| 2015 | — | Zell am See (AUT) — first European edition |
| 2006 | Inaugural | Clearwater, Florida (USA) |
Since when does it exist?
First held in Clearwater, Florida in 2006, the championship began rotating globally in 2014 — Mont-Tremblant, Zell am See (first European edition, 2015), Sunshine Coast, Chattanooga, Nelson Mandela Bay (first African edition, 2018), Nice and beyond.[2]
Why does it matter?
The 70.3 format is where most of the world's long-course professionals and serious age-groupers race; its world championship draws the deepest middle-distance fields in the sport, and qualification is a recognized competitive credential at both professional and amateur level.[1] [3]
