Age-group thresholds
IRONMAN 70.3 California Oceanside · 3 editions (2014, 2015, 2016) · 6,694 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.
