IRONMAN 70.3 Cascais Portugal · 8 editions (2017, 2018, 2019, 2021, 2022, 2023, 2024, 2025) · 15,519 finishers

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.
