Ironman updates their competition rules for 2026. This year’s rules formalize the 20-meter bike draft rules for pros, which they announced last month, and clarify how they will work when age groupers interact with pros. They also lessen the penalty for having an unzipped trisuit from disqualification to a warning and a time penalty if not remedied, ban video recording during races (so leave those Meta Oakley glasses home), and rename the Physically Challenged and Intellectual Disability Open Division to Para Open Division, plus a handful of minor wording changes. They’ve also published a summary of the changes and an FAQ.

Nothing too earth-shaking, but I’m surprised that after last year’s confusing changes to the hydration rules, which were only communicated by World Triathlon through a “rule interpretation” document and which Ironman said would only be enforced for pros with “ample notice” given before they took effect for age groups, none of those rules made it into either the 2026 Ironman or World Triathlon rule books, except for the one that limits attachments to the top tube of the bike to a maximum height of 10 cm. I’m assuming this means the rest of the rules in the “rule interpretation” document are still not in effect for age groups, but it would be nice to get some clarification from Ironman one way or the other.

No more Mortal Hydration in Ironman aid stations in 2026. From Ironman, via email:

Ahead of your race next year, we wanted to introduce you to Precision Fuel & Hydration, our Official Hydration Partner for the 2026 IRONMAN and IRONMAN 70.3 Global Series, including the 2026 IRONMAN World Championship in Kona, Hawai’i and the 2026 IRONMAN 70.3 World Championship in Nice, France.

Trusted by reigning IRONMAN World Champion Solveig Løvseth and 2x IRONMAN 70.3 Champion Jelle Geens, Precision Fuel & Hydration’s PH 1000 electrolyte drink will be available on-course globally next season.

I use PH 1500 tablets frequently during training in the summer and vastly prefer them to Mortal’s excessively-sweet, stevia-laden electrolyte drinks. This is great news, and exactly what I hoped would happen after Ironman announced Precision Fuel & Hydration as their hydration partner in Europe a couple of years ago.

Ironman announces new performance-based qualification for Ironman and Ironman 70.3 World Championships. This new system, which takes effect with the 2026 qualification cycle starting this month, basically does away with the old roll-down system, in which unclaimed slots would roll down indefinitely within an age group. Ironman has a good explanation in their FAQ, but the short version is:

• Each race is allocated a number of World Championship slots, as before.
• Winners of each age group automatically get a World Championship slot.
• If they decline it, the slot can only roll down to second or third place.
• Any unclaimed slots go to a global “Performance Pool” for that race.
• The finish times of the remaining athletes are normalized by multiplying them by some factor for each age group, so they can be ranked together.
• This factor is derived for each age group from the top World Championship finish times over the past five years, and will be updated every year.
• The remaining slots are offered to the top finishers in this age-graded normalized ranking, and roll down until they’re all claimed.
• For Kona, there’s a single age-graded ranking including men and women; for 70.3 Worlds there are separate rankings for men and women, since they’re separate races.

It sounds complicated, but the examples they have in the FAQ make it easier to understand:

Anne is 42, she finishes IRONMAN Kalmar in 9:19:51, giving her an age-graded finish time of 8:07:26, applying the Kona Standard of 0.8707 (9:19:51 × 0.8707 = 8:07:26). John is 43 and finishes IRONMAN Kalmar in 8:50:31, giving him an age-graded time of 8:33:42, applying the Kona Standard of 0.9683 (8:50:31 × 0.9683 = 8:33:42).

Anne would rank above John in the age-graded rankings due to her age-graded time of 8:07:26 being faster than John’s age-graded finish time of 8:33:42.

For me, this means any hopes I had of getting lucky with a deep roll down in my age group at a late-season race are probably dashed, but I like this change; it makes qualification fairer and more competitive. I’ll simply have to git gud, or outlive everyone and qualify in the 90–94 age group.

Ironman will not enforce the new World Triathlon hydration rules for age groups just yet. Jimmy Riccitello, Ironman’s head referee, confirmed this to Slowtwitch on the Slowtwitch Podcast. The new rules World Triathlon announced in April (and clarified again in May) in their rule interpretation document are in effect, but Ironman will currently only enforce them for professional athletes, and will provide “ample notice” of at least thirty days before they take effect for age groupers.

Good news, but this is such a mess. Maybe I’ll write an explainer later about the new rules, since we’ll eventually have to abide by them, but for now, if you are an age grouper competing in an Ironman-branded race, the only hydration rules you need to worry about right now are the ones in section 5.02 (c​) of the Ironman 2025 competition rules, which are summarized here and explained in this FAQ.

TL;DR: As many bottles as you want in the front, up to two liters total; and up to two bottles in the back, of no more than one liter each.

Ironman adopts World Triathlon’s bike hydration rules. Well, that was fast. On Sunday I wondered if Ironman would adopt World Triathlon’s new rules limiting the amount of hydration that can be carried on the bike, and today I got my answer: Yep. In the 2025 Ironman competition rules, the section on bike equipment has been updated to be consistent with World Triathlon rules:

(i) Front Mounted Water Bottles and Hydration Systems mounted to components attached to the bike that rotate around the steering axis (e.g., cockpit extensions, top tube, headset, stem, head tube) must have a combined maximum volume capacity of no more than two (2) liters (this excludes water bottles and hydration systems located inside the frame triangle of a bicycle or inside the bicycle frame) (DSQ).

(ii) Rear Mounted Water Bottles and Hydration Systems are limited in size, capacity, dimension and location as set forth below:
(i) Cannot contain more than two (2) water bottles* (DSQ); and
(ii) Must not exceed one (1) liter capacity per bottle* (DSQ).
*Excludes water bottles and hydration systems located inside the frame triangle of a bike or inside the bike frame.

Here’s a full summary of the updated competition rules, which include a few other verbiage changes and updates for consistency with World Triathlon. Among other things, the penalties for blue card violations, such as drafting and littering, have been reduced to 3 minutes for full Ironmans and 2 minutes for 70.3s (down from 5 minutes for both). The rules also clarify that you can wear neoprene hats whenever wetsuits are allowed and that you can wear two swim caps (in both cases you still have to wear the race cap on top). Ironman also has a short FAQ that explains the changes very clearly.

After training for it for the better part of a year, it’s finally time for Ironman Canada, my A race of this year and my second attempt at a full Ironman, following my DNF at Ironman Coeur d’Alene last summer, where despite a good swim and a strong bike leg, things went sideways during the run and I barely made it 16 km before bonking.

This year’s Ironman Canada will be the last in Penticton. Not entirely surprising; I thought the writing was on the wall when they unveiled another Ironman Canada in Ottawa, but they just made it official today. This is a huge bummer for me personally; I don’t think there are any other full-distance races that are within a reasonable driving distance, and I don’t want the hassle of flying with my bike and gear. This puts a lot more pressure on me to finish this year’s race—I might not have another shot at a full Ironman anytime soon. It’s do or die.

Well, this is it. After training for it since November, I finally raced Ironman Coeur d’Alene, my A race of the year and my first attempt at a full Ironman. I didn’t have any specific time goals for this race, just finishing, so the goals I had set for myself were simply:

1. Don’t drown
2. Don’t crash
3. Don’t bonk

Unfortunately, things did not go according to plan, and despite my best efforts, I was not able to finish the race. Read on for what may be my last triathlon race report of this year.
