IRONMAN Japan · 9 editions (2006, 2007, 2008, 2009, 2013, 2014, 2015, 2024, 2025) · 8,282 finishers
Editions: 2006 · 2007 · 2008 · 2009 · 2013 · 2014 · 2015 · 2024 · 2025
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.
