Ironman Texas: Past Performances and Kona Qualification

Latest statistics for Ironman Texas

Lanzarote isn’t the only Ironman this weekend, on the other side of the Atlantic Ironman Texas will also take place; which means I’m posting my second pre-race analysis of the week. This is the fourth running of the race and weather over the last 3 years has varied with hot, challenging conditions in 2013 resulting in a high rate of DNF and slower finishing times. Despite this variation competition for the 50 Kona slots has remained consistent.

I’ll start by reviewing the summary data, but age group specific details are available at the end of this post.

The two sets of histograms above give a very broad picture of the nature of racing Ironman in Texas and North America as a whole. Of course they also hide much of the detail, amalgamating the much slower times of 2013 with the previous 2 years at Ironman Texas for example. It’s imperfect, but offers some basis for comparison with other races. For the most part, at least considering the overall finish splits, Ironman Texas is not significantly different from the other US races. Times are slightly slower, but the margin is small. Within the individual disciplines we can see that bike times in Texas are distinctly faster and run times slower; of course some of this variations may reflect the weighting of the 2013 event (particularly the slower run times).

Typical Distribution of Splits at Ironman Texas

Looking at last year’s pre-race analysis, the 2011-2012 distribution (above) doesn’t vary that much from this year’s 2011-2013 charts. While 2013 did add weight at the slower end of the run, it didn’t hugely shift the distribution. Texas appears to have a faster bike and slower run than the typical North American pattern.

The median charts usually confirm observations from the distributions and this is once again the case. Swim averages are a little slower, bike distinctly faster and run distinctly slower in Texas than in other US races. For the pros the only significant difference is the faster average bike, while the broad age group picture points to a slower run this isn’t true at the sharp end of the field. Again, looking back at last year’s charts, eliminating 2013 results doesn’t change the pattern.

M75-79 4 1
M80+ 1 1
Total 2663 50

There are 50 Kona slots available to athletes at Texas and using the bib list available on the site I’ve estimated the above allocation of those places. Actual numbers will vary on the day, but the distribution seems typical of a 50 slot race with M40-44 taking the biggest share.

Front of pack performances have remained consistently fast over the 3 years of the events regardless of conditions. Qualifying times vary with division, but for the major male age groups it’s likely to be around the 9:30 mark, some will require more, some less. For the women’s field the average tends to run around the 10:30 mark, but again can dip down as low as 10:00. Basically, as we should expect, regardless of course and conditions those looking to qualify need to be fast.
