Which States Produce The Most Ironmen And Ironwomen?

In keeping with my current trend of statistically analyzing the results of past Ironman races, I began to wonder which states produced the most Ironmen and Ironwomen per capita. Well, I wonder no longer. I looked at about 60,000 American triathletes who raced in Ironman and half-Ironman races from 2010-2017 and broke them down by which state they came from. (This is just a subset of all Ironman racers, and is by no means complete).

The below table shows each state’s ranking, with their ratio of Ironmen-to-population. A ratio of more than 1 means they produced more Ironmen than expected based on their population (nice job, Hawaii), whereas a ratio of less than 1 means they produced fewer (looking at you, North Dakota).

Alright, now what else can we look at? How about gender distribution of triathletes from each state? Not a problem. Louisiana, it looks like you’ve got some work to do. Don’t overlook California, too – this state produces the most triathletes by far, and is still suffering from a 64/36 male/female split. We’ve actually written another article on the trend towards more women competing in Ironman races, but it appears that the Golden State hasn’t yet gotten the memo.
