Age-group thresholds
IRONMAN 70.3 Mandurah · 3 editions (2013, 2014, 2015) · 2,654 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.
