Age-group thresholds
IRONMAN 70.3 Miami · 8 editions (2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017) · 16,140 finishers
Editions: 2010 · 2011 · 2012 · 2013 · 2014 · 2015 · 2016 · 2017
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.
