Age-group thresholds

IRONMAN UK Leeds · 2 editions (2025, 2026) · 2,428 finishers

Editions: 2025 · 2026

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.
