Age-group thresholds
IRONMAN 70.3 Washington Tri-Cities · 3 editions (2024, 2025, 2026) · 5,597 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.
