Age-group thresholds, all IRONMAN 5150 races

12,209 finishers, every edition in the archive · updated 2026-10-29

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.
