Challenge Roth 2018: Age Group Results

Steeping away form the Ironman brand for the third analysis this week with the biggest race of the weekend – Challenge Roth. There are no Kona slots to consider here, just a famous course and fast times. This year’s race looks to be a typical year for Roth.

Distribution of Finisher Splits at Challenge Roth 2018 Compared with 2010-2017

The 2018 splits distribute very similarly to the previous 7 years of race results. Perhaps the only variation to mention is with the bike distribution which trends slightly slower than the amalgamated data from previous races. Differences are small and largely balance out when we look at the overall distributions.

There are enough problems with the way results have been presented over the years that DNF data is at best sporadic. There’s nothing exceptional about the statistics from this year’s race – they don’t appear to represent a high or low for the course.

Probably the most famous Iron distance race outside the Ironman brand – Roth draws a field from around the world.

Changes in Male Finishing Times by Position at Challenge Roth
Changes in Female Finishing Times by Position at Challenge Roth

Prior to 2014 Roth’s results included professional in with age groupers, so the first thing you’ll note in the above charts is some very fast times (off the charts) in the 25-35 age range. Min more recent years the pros have been listed in their own categories. With that in mind we can still see that Roth has had quite a stable set of results over the years. This year follows that pattern.

Finally the top twenty within each age group. Those pro times do skew things a little here so perhaps I need to start dropping those results from future analysis. Still the trend is around the existing average line with some variation between age groups.
