Age-group thresholds

IRONMAN 70.3 Western Australia · 9 editions (2016, 2017, 2018, 2019, 2021, 2022, 2023, 2024, 2025) · 7,594 finishers

Editions: 2016 · 2017 · 2018 · 2019 · 2021 · 2022 · 2023 · 2024 · 2025

How to read it: in each row, the time under "Top 10%" is the time of the slowest athlete who still made the fastest 10% of the age group. Beat that time and you are in. Age groups with fewer than 5 finishers are omitted. Finishers only.
