Ironman is considering evidence provided by Women in Tri UK regarding the corporation’s proportional representation world championship slot allocation system. The report produced by the UK charity dedicated to supporting gender equality in sport, was recently shared with Ironman. It outlined how Ironman’s current slot allocation system is unfair to high-performance female age group athletes.
The report backs up other evidence recently shared online and directly with Ironman establishing a strong case for modification to its current proportional representation system. While Ironman has said it appreciates the information, it did not outright commit to modifying its current system to a more gender equitable scenario that rewards high-performing female athletes over less competitive men when awarding world championship slots.
As the charity organization has emphasized, beginning in 2026 when the Ironman World Championship returns to a one-day event in Kona with men and women competing together, the shift back to proportional representation eliminates equal gender representation at the world championships, and gives slots to men who finish with slower times and further down in their age-group rankings, than more competitive women.
Evidence shows less competitive men awarded slots
In its report, Women in Tri UK summarizes the crux of the issue.
“In many races, women receive far fewer slots despite producing a greater share of top performances. The outcome is a World Championship start list that does not reflect the true competitive landscape.”
In the report’s forward, Canadian professional triathlete, Tamara Jewett commented on the imbalance of having two different slot allocation process for pro and amateur athletes, in which the women’s pro field has equal slots to the men. She also commented on basing slot allocation on participation numbers.
“Are participation numbers the best indicators of competitiveness? While assigning Kona slots based on size of field may at first seem intuitively fair to some, when you start to dig into it and look at some data, there is a strong argument that it is not very fair,” Jewett wrote.
“If the goal is to expand women’s participation in the sport, extensive data and experience from other sports show that things like equal qualification spots and equal prize money and funding drive women’s participation in sport,” she continued.
“Essentially, they point to evidence that suggests that trying to increase opportunities at the highest level of a sport is getting things a bit backwards. An important part of this position is that changes to women’s participation take 20-30 years of commitment. Whereas, Ironman has given equal qualification for its full-distance World Championship only about three years before changing.”
The numbers don’t lie
From the analysis of 35 Ironman races between May 2024 and April 2025, Women in Tri UK proved that despite women only making up 17 per cent of participants, they represented a larger number of top-performances in comparison to some slots allocated to men. The data highlights how women are twice as likely to finish at the top of their age group then men. Despite this, proportional representation tips the slot balance in such a way that, often, men with slower times than higher-performing females, and who finish low ranked in their age group than the faster female, will be awarded the world championship slot.
The report refers to top-performing athletes as those that finish in the top 15 per cent of their age group. Under the current system, women in the top 15 per cent lose out to men who finish below the top 15 per cent based on the single fact that male participation numbers are higher. A strong example is Ironman Texas, where women accounted for 28.45 per cent of participants, a number that is higher than usual, and produced more top athlete performances than men. The evidence shows that there were 94 top-performing women compared to 90 top-performing men, and 51 per cent of overall top-performers were age group women. Yet, more slots went to men, while faster, high-ranking females lost out.
Ironman Taiwan presents an even larger gap. Female participation numbers were only 18.99 per cent, and yet they represented 38 per cent of top-performers, compared to 8.5 per cent of men falling into the top-performer category. Overall, this resulted in a total of 57 female top-performers versus 55 male top-performers in a field where women participation accounted for less than 20 per cent.

Ironman releases “measured” response
Ironman’s Vice President of Global Marketing, Peta Bell, released a statement to Women in Tri UK in response to the data.
“Ironman appreciates the enthusiasm around our decision to bring our community back together, as we return to our historic roots in Hawai`i for the IRONMAN World Championship in Kona. We also value the constructive ideas and feedback shared to further enhance the pinnacle event in triathlon, inclusive of research and consideration pertaining to slot allocation. As we’ve demonstrated over our history, Ironman’s path is evolutionary and we will continue to review data, seek feedback, and iterate as we further enhance our events,” said Bell.
“We have had very positive dialogue with Women in Tri UK and they are among a number of organizations and individuals that are important to the collaborative discussions necessary for the long-term growth of women in triathlon. We appreciate the time, effort, and thoughtful approach put into their research, and look forward to continued discussions with them and others as we consider our final approach to 2026 slot allocation—along with other ideas that can help grow women’s participation in the sport and shape a fair, competitive World Championship that excites and inspires both current and future athletes.”
As review of the data and discussions continue between Women in Tri UK and Ironman, the final decision on how the slot process will unfold for the first reunion in Kona remains outstanding. As with women in sport, the road to Kona continues to evolve.
