IRONMAN Announces Evolution to the 2026 IRONMAN World Championship Age-Group Qualification System and Release of Qualification Data and Insights

November 15, 2025

— Data for first third of qualifying cycle released, alongside updates to system to address imbalance seen in performance pool slots.

— IRONMAN remains committed to ongoing evaluation, review, and transparent reporting of Performance-based Qualifying System.

TAMPA, Fla. (November 15, 2025) /ENDURANCE SPORTSWIRE/ – IRONMAN, the global leader in triathlon, today released comprehensive data and insights to support transparency and evaluation into the current results of the new IRONMAN World Championship® Performance-Based Qualifying System. Introduced earlier this year, for the 2026 qualifying cycle, the system was designed with a commitment to ongoing monitoring, with the intention of evolving it as needed. Following an in-depth review of the results from the first third of qualifying races for the 2026 cycle which has been in progress for the past month, IRONMAN, in consultation with the athlete-led IRONMAN® Championship Competition Advisory Group (ICCAG), will be making retroactive and forward-looking changes to the 2026 IRONMAN World Championship slot allocation system, including splitting the performance pool slots by gender and keeping Automatic Qualifying Slots roll down within gender. The changes will be focused on further ensuring access to and representation at the IRONMAN World Championship, while maintaining a performance-based philosophy.

Scott DeRue, CEO of The IRONMAN Group said: “When we launched our qualifying system earlier this year, the goal was simple; to give every athlete the same opportunity to qualify based on performance. Early feedback on this approach was met favorably, and we continue to believe in the foundation of this philosophy. However, there are certain elements of the new system that are not playing out as we expected, and we now have sufficient data to make informed decisions – for the overall health and long-term growth of the sport.”

2026 IRONMAN World Championship Slot Allocation Data and Insights:

In July, IRONMAN introduced a new performance-based world championship slot allocation system set out to reward every age group winner as well as athletes, who on a relative basis within their gender and age group, are most competitive. For each qualifying event, both women and men are eligible for up to 15 Automatic Qualifying Slots (Age-Group Winners slots), however the final allocation is based on age groups with finishers. How slots ultimately get allocated within an individual race have been determined entirely by individual performances on race day, how competitive athletes are on a relative basis to their peers when compared to their age-group standard, and ultimately the decision of athletes on whether they accept the slot.

Participation and Acceptance Rates – What We’re Seeing

With just over a third of the 2026 IRONMAN World Championship qualifying events complete, IRONMAN has seen the following as it relates to slot allocation and athlete behavior:

  • To date, approximately 96% of performance pool slots are going to men, and 4% to women
    • Pre-implementation testing of the new system using historical data showed a performance pool split closer to 15-20% for women and 80-85% for men. If true, when combined with the automatic qualifying slots for age-group winners, this would have resulted in women earning 30-35% of all slots by the end of the season.
  • Men have represented 84.4% of overall finishers, while women have represented 15.6% of finishers
  • Based on first-offer acceptance, women were offered ~24% of slots and accepted 20.3% of slots overall
  • Approximately 15% of women’s Automatic Qualifying Slots have rolled to the performance pool (i.e. have not been accepted by women’s podium athletes). By comparison, only 3% of men’s Automatic Qualifying Slots rolled to the performance pool.
    • These results have reduced the actual slots women are receiving and negatively skewing actual slot allocation from events

What We’re Learning

Feedback from athletes, surveys, and early discussions with our IRONMAN Championship Competition Advisory Group highlight the below:

Top Competitive Athletes Competing at 2025 World Championship Events:

      • This year, around 60% of the top-performing women (based on global rankings) competed in the 2025 IRONMAN World Championship in Kona. In comparison, around 20% of the top-performing men raced in the 2025 IRONMAN World Championship in Nice. As a result, a greater majority of the fastest women have not yet entered qualification races for 2026.
      • This dynamic may have suppressed aggregated performance in female age groups at qualifying races to date (i.e. a higher index of the fastest/strongest female athletes were not racing compared to men, and thus resulting in a larger performance pool gap)
      • While future events may help rebalance this, there’s no guarantee.

Slot Declines and Roll-Down Dynamics

      • IRONMAN surveyed athletes who were offered a slot but did not accept. Two key factors came from women that was different from men: wanting more time to make a decision, and family obligations, particularly related to having young children. When performance pool slots are combined across genders, any slot declined by a woman is more likely to go to a man simply because men make up about four times the number of women participants currently.

What Are We Doing:

Beginning immediately (including IRONMAN Arizona triathlon this weekend), IRONMAN will be making the following updates to the system:

Performance Pool Split by Gender: Performance pool slots will now be awarded separately for men and women. Men and women will have their own performance pools, and the number of slots in each gender’s pool will match eligible age group starter representation in that race, thus preserving our performance-based allocation principles while supporting distribution across men and women

Automatic Qualifying (Age Group Winner) Slots Remain within Gender: Winner slots that previously rolled within the podium of the respective age group prior to moving into the overall performance pool, will now roll down within the respective gender’s performance pool.

Provide Retroactive Winner Slots to Performance Pool: For IRONMAN races already completed in the 2026 qualifying cycle, we will retroactively apply these changes and offer slots to any athlete – women and men – who would have earned a slot had these changes been implemented initially. This means the 24 women’s Automatic Qualifying slots and 8 men’s Automatic Qualifying slots that rolled into the combined performance pool so far this season will be retroactively offered to the men and women who would have earned these slots. In addition, we will retroactively allocate performance pool slots from past races to athletes who would have qualified if the performance pools had been split between men and women from the beginning (44 slots will be retroactively awarded to women). Retroactive slot allocation will be made automatically in the coming days to eligible athletes. If the slot is not taken, it will continue to be offered to the next highest-ranked athlete within the respective gender.

Ongoing Monitoring and Transparent Reporting: IRONMAN will continue to closely track slots offered and acceptance patterns at upcoming qualifying events, periodically meet with the ICCAG to evaluate, and publish updates on slot allocation and acceptance rates as the qualifying season progresses.

The steps taken with these changes reinforce the organization’s commitment to transparent, data-driven evaluation, and principled action while utilizing outside consultation with the ICCAG.

In a letter to the IRONMAN community which was shared today, Scott DeRue, CEO of The IRONMAN Group said: “Our collective aim is to inspire athletes globally to experience the joy, the sense of belonging, and the feeling of personal achievement that are woven through the sport of triathlon. Triathlon is life-changing for so many people around the world, and we are committed to a system that ensures athletes have an opportunity to live their IRONMAN World Championship dreams.”

IRONMAN Championship Competition Advisory Group

With the changes to the age-group qualifying system implemented ahead of the 2026 qualifying cycle, IRONMAN created the IRONMAN Championship Competition Advisory Group to provide a forum for a representative group of age-group athletes to offer input and feedback on the new qualification system and to help identify any elements of the system that need to be refined. This group is made up of a diverse cross-section of the IRONMAN audience, spanning ages, genders and geographies selected for their experience, perspective, and dedication to the sport.

About the IRONMAN World Championship

On February 18, 1978, 15 competitors came to the shores of Waikiki, Hawai`i to take on the first-ever IRONMAN® triathlon. It was an idea hatched by John Collins, a Naval Officer stationed in Hawai`i, and his wife Judy during a swim club gathering. Collins’ proposal was a friendly test of fitness combining the three toughest endurance races on Oahu into one race: The 2.4-mile Waikiki Rough-water Swim, the 112-mile Around-Oahu Bike Race, followed by a 26.2-mile run on the Honolulu Marathon course. That first race would set the stage for what IRONMAN triathlon would become: the most-challenging single-day sporting event in the world, and a brand symbolizing the belief that “ANYTHING IS POSSIBLE®.” Since its inception in 1978 on the Island of O`ahu, the IRONMAN World Championship® triathlon has etched its name in history through historic performances, inspiring athletes, and a lifetime of memories that define the sport of triathlon today. In 1981, the race moved from the tranquil shores of Waikīkī to the rugged lava fields of Kona on the Island of Hawai`i. The most iconic one-day sporting event in the world is the culmination of 40 global IRONMAN events with over 94,000 athletes around the world striving for one of the coveted qualifying slots of any sporting event in the world.

ANNEXURE: Media Factsheet

A: Key Terms

Kona Standard 

A performance benchmark that is used to equalize age group athletes’ finisher times. The standard is created by taking a rolling five years of finisher data from the IRONMAN World Championship (Kona), and isolating the top 20% of performances, per age group. From each age group sample an average is created, resulting in one representative fastest finisher time per age group per gender.  The fastest finisher time among the age groups is identified and all other average age group times (standards) are compared back to the fastest finish time to generate a relative ratio for each age group.

IRONMAN 70.3 Standard (‘70.3 Standard’)

A performance benchmark that is used to equalize age group athletes’ finisher times. The standard is created by taking a rolling five years of finisher data from the IRONMAN 70.3 World Championship events, and isolating the top 20% of performances, per age group. From each age group sample an average is created, resulting in one representative fastest finisher time per age group per gender.  The fastest finisher time among the age groups is identified and all other average age group times (standards) are compared back to the fastest finish time to generate a relative ratio for each age group.

The IRONMAN 70.3 Standard will change from one year to the next as the rolling five years of data changes. This serves as a consistent, benchmark that evolves as finisher times improve from year to year.

Age Grading 

The method that adjusts each athlete’s time based on their age, against the fastest age group, allowing athletes of different ages to be compared fairly.

Age Graded Finish Time 

The athlete’s finish time after applying the Age Grading. This represents their performance that is comparable to any athlete in their gender.

Automatic Qualifying Slot 

A World Championship qualifying slot that is guaranteed to each Age Group winner at any given event. If the Age Group winner declines the slot, it will be offered to (roll) to the second-place finisher, and then to the third-place finisher if not taken by the second-place finisher. If the Automatic Qualifying Slot for a specific age group is not taken by one of the top three finishers, that slot is then allocated to the overall ‘Performance Pool’ of qualifying slots that will then be offered to the next-most competitive athletes at the same event.

Performance Pool Slot 

This is the amount of Age Group qualifying slots that remain after the Automatic Qualifying Slots are allocated to the Age Group winners. Performance Pool slots are offered to the next-most competitive athletes at the same event once the Age Grading system is applied.

To do so, all remaining athletes are ranked based on their age-graded finish times (i.e., their performance in the race relative to their own age-group standard); the athletes who are most competitive on race day relative to their age-group standard will rank highest.

Slots from the Performance Pool will then be allocated using a ‘first to accept’ roll-down process, starting from the highest ranked athletes. This roll-down process will continue until all qualifying slots are allocated.
