A lot of the male age group medians appear improved in this years race compared with the aggregated data. Although this is not the case for the youngest age groupers. The women’s results are more varied in comparison, with some faster age group medians and some slower. It’s worth also noting both male and female pro medians were faster at this year’s event.

The above table uses my calculation for slot allocation based on the athlete tracker numbers, from there it calculates qualifying times assuming no roll down. Final start numbers may have varied and the qualifying time with that. You can compare this with other races on my Kona qualification page.

Taking those automatic qualifying times I’ve then determine the nationalities of qualifiers to see where the Koan slots went. As is normally the case the majority went to the home nation, the remainder were picked up by US and European athletes.

Top Twenty Male Performances and Kona Qualification by Age Group at Ironman Western Australia 2016
Top Twenty Female Performances and Kona Qualification by Age Group at Ironman Western Australia 2016

One thing that’s clear is while the medians look the same as usual, the top twenty in most male age groups were well ahead of the averages. Times are up there with the fastest races in Western Australia. This is also the case for a few of the female age groups, those between 35 and 50. Outside of that results are closer to the averages or slower.

Overall it looks like conditions were quite fair and enabled some fast times at the front of the race. This was balanced out across the field though which kept the medians in line with previous results. I’d put 2016 as a faster than average race in Busselton.
