Age-group thresholds

IRONMAN 70.3 Brasilia · 1 editions (2025) · 1,414 finishers

Editions: 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.
