What time do I need to qualify for Kona in my age group?

There is no longer such a number, and any site still publishing one is describing a system that no longer runs. From the 2026 qualifying cycle IRONMAN stopped allocating slots per age group. Beyond one automatic slot for each age-group winner, the remaining slots go to the fastest age-graded finishers across the whole field, so what it takes depends on who else raced that day.

How does Kona qualification actually work now?

The winner of each age group earns an automatic slot, rolling to second and then third if declined. Every remaining slot goes into a Performance Pool, split by gender in proportion to starters, and is offered to the fastest age-graded finishers in order until the slots are taken. IRONMAN describes the Kona Standard as a benchmark rather than a cutoff.

Why are the Kona and 70.3 standards different?

They are built from different championships. The Kona Standard is referenced to the 30-34 age group for both sexes; the 70.3 Standard is referenced to men 18-24 and women 25-29. Using one for the other distance would give you a wrong number.

Why is there no ratio for women aged 80 and over?

Because IRONMAN publishes none. The standards are built from World Championship finishers over a five-edition window, and there have been no finishers in those age groups within it. We show TBD rather than inventing a multiplier.

Qualifying

Kona Qualifying Calculator

IRONMAN stopped allocating World Championship slots by age group in 2026. Slots now go to the fastest age-graded finishers, so the useful question is no longer what time your age group needs - it is what your time becomes once age-graded. This applies IRONMAN's own published multipliers.

Age-grade your finish time

Enter a finish time and this applies IRONMAN's published multiplier for your age group and sex. The result is the number the qualifying system actually ranks athletes on.

StandardSexAge on race dayAge group 40-44Finish timeAs h:mm:ss

Age-graded time

11:08:08

11:30:00 at age 42 (40-44) grades with a multiplier of 0.9683, which credits you 21:52. That is your time expressed against the 30-34 reference group.

This converts a time; it does not tell you whether you qualified. Under the system in force from 2026 the slots left after the automatic ones go to the fastest age-graded finishers at that race, so the cut depends on who else raced that day and cannot be known in advance. IRONMAN states plainly that the Kona Standard “is not a cutoff time”.

Why “qualifying time by age group” no longer exists

Search for a Kona qualifying time and you will find tables of times by age group. Every one of them describes a system that IRONMAN retired. In its own words: “Slots will no longer be allocated to each age group based on how many people are racing within that age group.”

What replaced it has three moving parts:

Automatic Qualifying Slots. The winner of each age group earns one. If declined it rolls to second, then third.
The Performance Pool. Every slot left after the automatic ones goes into a pool, and is offered to the fastest age-graded finishers regardless of age group.
Roll-down. The list is worked down until every slot is accepted.

The consequence is that no time guarantees a slot. What it takes at any given race depends on the age-graded times of everyone else who raced it. IRONMAN is explicit that the Kona Standard “is not a cutoff time. It is a global benchmark”.

The system was revised once already

A third of the way into the first cycle, IRONMAN reported that 96% of performance-pool slots had gone to men - against a modelled expectation of 80 to 85%. Women made up around 16% of finishers but had earned about 24% of total slots, well short of the 30 to 35% the design had predicted.

Three changes followed: men and women now have separate performance pools sized to their share of starters at that race; automatic slots that go unclaimed stay within the same gender rather than falling into a combined pool; and slots were offered retroactively to women who had been affected.

If you are reading elsewhere that this revision happened in November 2026, that is an error propagated from IRONMAN's own main qualification page - their update page is dated 6 November 2025 and headed “Update, as at November 14, 2025”.

Kona Standard: official age-grading multipliers

For IRONMAN 140.6. Multiply your finish time by the ratio for your age group and sex. Both reference groups are 30-34, which is why they read 1.0000.

Published by IRONMAN, derived from averaging the top 20% of World Championship finish times over five editions. TBD means IRONMAN publishes no value because there have been no finishers in that group within the window.

70.3 Standard: official age-grading multipliers

For IRONMAN 70.3. Note the reference groups differ from Kona - men 18-24 and women 25-29 - so these are not interchangeable with the table above.

70.3 Standard: official age-grading multipliers

75-79	0.6419	0.6234
80-84	0.5095	TBD
85-89	0.5402	TBD

The 70.3 World Championship runs as a two-day men's and women's event, so each race offers an equal but separate number of slots to men and women.

What this means for planning a season

Winning your age group is the clean route. It is the only outcome that earns a slot outright rather than depending on the rest of the field.
Older athletes are treated better than before. Age grading credits a 60-64 man about 17% and a 70-74 man about 31%, so a strong performance later in life now competes directly with the front of the 30-34 group.
Race choice matters more, not less. The cut is set by whoever else turned up, so a deep field raises it regardless of how you performed.
Work backwards from a target time. Use the pace chart to see what an age-graded target demands leg by leg, and the race predictor to check it against your current fitness.

Frequently asked questions

What time do I need to qualify for Kona in my age group?: There is no longer such a number, and any site still publishing one is describing a system that no longer runs. From the 2026 qualifying cycle IRONMAN stopped allocating slots per age group. Beyond one automatic slot for each age-group winner, the remaining slots go to the fastest age-graded finishers across the whole field, so what it takes depends on who else raced that day.
How does Kona qualification actually work now?: The winner of each age group earns an automatic slot, rolling to second and then third if declined. Every remaining slot goes into a Performance Pool, split by gender in proportion to starters, and is offered to the fastest age-graded finishers in order until the slots are taken. IRONMAN describes the Kona Standard as a benchmark rather than a cutoff.
What is age grading and how is it calculated?: Your finish time is multiplied by a published ratio for your age group and sex. The ratios come from averaging the top 20% of World Championship finish times over five editions, so they reflect what the front of each age group actually does. Multiply, and you get a time comparable across ages.
Why are the Kona and 70.3 standards different?: They are built from different championships. The Kona Standard is referenced to the 30-34 age group for both sexes; the 70.3 Standard is referenced to men 18-24 and women 25-29. Using one for the other distance would give you a wrong number.
Why is there no ratio for women aged 80 and over?: Because IRONMAN publishes none. The standards are built from World Championship finishers over a five-edition window, and there have been no finishers in those age groups within it. We show TBD rather than inventing a multiplier.
Did the qualifying system change again after it launched?: Yes. IRONMAN reported that after a third of the cycle, 96% of performance-pool slots had gone to men, against an expectation of 80-85%. Men and women now have separate performance pools sized to their share of starters, automatic slots stay within gender, and slots were offered retroactively to women affected.
