IRONMAN 70.3 California · 8 editions (2005, 2007, 2008, 2009, 2010, 2011, 2012, 2013) · 16,220 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.
