2026 IRONMAN World Championship — Kona Playbook
Kailua-Kona, Hawaiʻi · October 10, 2026 · Race week, course intelligence, pacing, fueling, heat management, logistics, equipment, and mental execution
Kona is hard because the conditions keep adding cost to otherwise normal decisions.
The swim is warm, the bike is exposed, the wind can change quickly, and the lava throws heat back at you. By the time you reach the quietest parts of the run, you have already been managing all of that for hours. Add a World Championship field around you and sensible pacing can look slow.
That changes how you have to race it.
You already did the work to get here. On race day, the point is to use it. Stay patient early, keep fueling even when it becomes inconvenient, start cooling before you feel hot, and wait until the marathon gives you enough information to decide what is left.
Patience keeps the race open. You want something left when the final 90 minutes arrive.

What Makes This Race Different
Kailua Bay
5,814 ft / 1,772 m gain
Aliʻi · Queen K · Energy Lab
Exposure · Humidity · Solar load
Kona is hot and windy, but that description misses the bigger issue: the stress keeps stacking. You are warm from the swim onward. By the time the run gets hard, you may already be carrying hours of heat, fluid loss, fueling stress, wind exposure, and race-day excitement.
The terrain is moderate by IRONMAN standards, which is part of the trap. There is no huge climb forcing you to back off. There are long stretches where it is very easy to spend too much without realizing it.
The Five Kona Problems
- A World Championship field can distort your sense of pace. People around you will be moving quickly. That does not make their pace your pace.
- Wind makes speed a poor guide. Bike speed can change a lot with almost no change in effort. Use power, HR, RPE, and how you feel—not mph.
- Heat can get ahead of you before you notice it. Cooling and hydration must begin while you still feel fine.
- Bike mistakes often show up late. Over-riding early may not hurt until mile 80, or until the Queen K on the run.
- The run gets quiet right when you are starting to hurt. Aliʻi gives you plenty of outside energy. On the Queen K and in the Energy Lab, you need to create your own.
02 / Final 3–4 Weeks
Arrive Rested and Ready for the Heat
The final weeks are about arriving ready to use the fitness you already have.
Training Priorities
- Preserve frequency while reducing total stress.
- Keep short race-specific exposures to bike power, run effort, and swim tempo so race feel stays familiar.
- Practice non-wetsuit swimming if that is not normal for you.
- Keep some steady aero work in the plan. You need to be comfortable holding position and producing controlled power for a long time.
- Use windy outdoor days as handling practice instead of avoiding them.
- A missed workout inside the final 10–14 days does not need to be repaid with a harder one.
Equipment Certainty
Every major race-day choice should be settled before travel: wheel depth, helmet, hydration storage, race kit, swim skin, goggles, shoes, socks, run hat/visor, nutrition storage, computer screens, tire choice, gearing, and repair kit.
03 / Heat Acclimation
Get Ready for the Heat Without Wrecking the Training
Heat acclimation should prepare you for Kona without compromising the training. The goals are straightforward: improve plasma volume and sweating response, get more comfortable training hot, and reduce the shock of race-day heat.
Practical QT2 Approach
- Begin about 2–3 weeks out if home is much cooler than Kona.
- One heat exposure per day is plenty.
- Use overdressed easy runs, indoor trainer/treadmill sessions with reduced cooling, or sauna exposure.
- Place sauna after training when possible, especially after the day's harder work.
- Build sauna duration gradually. The first session does not need to be heroic.
- Keep key quality sessions productive. Heat work should support the training, not ruin it.
- Keep practicing race-day fluid volumes during the heat block. Your gut needs practice too.
What Heat Acclimation Does Not Do
It will not make Kona feel cool or eliminate cardiac drift. It just gives you a little more room to work with.
04 / Travel & Arrival
Give Yourself Enough Time
QT2's 2025 Kona race recap was useful here because the athletes had just lived it. Athletes who arrived roughly a week ahead liked having time to adjust to the heat and time zone, preview the course, swim in Kailua Bay, and avoid cramming everything into the final few days. An athlete who arrived Tuesday said she would go a few days earlier next time.
How Early?
There is no magic number. If your schedule allows it, arrive early enough that the final four days are not packed with travel recovery, bike assembly, ocean swimming, course recon, check-in, the expo, and social plans.
Travel Logistics
- Book bike travel with an airline whose bike policy you understand before arriving at the airport.
- Know the bike-case weight limit. Kona return trips invite athletes to throw souvenirs into the case and accidentally exceed it.
- Bring irreplaceable race nutrition and small race-specific equipment with you rather than relying on island inventory.
- Choose lodging with race morning in mind. Staying near Aliʻi Drive can make the week much easier.
- If staying north of town, study road-closure and shuttle rules as soon as 2026 information is released.
Time-Zone Strategy
For mainland athletes, particularly East Coast athletes, the natural tendency to wake early can be useful. Race morning begins early. There is no requirement to stay awake late enough to “be on Hawaiʻi time” if going to bed early and waking early is helping you sleep.
05 / Race Week
The Week Is Part of the Race
Kona gives you endless ways to spend energy before race day: training swims, athlete events, sponsor activations, expo time, the Parade of Nations, underpants run, friends, restaurants, pros everywhere, and constant movement along Aliʻi Drive.
Enjoy it. Just be selective.
Worth Doing
- Swim the actual course. If you do not swim in the ocean often, this is worth doing.
- Official practice swim, if schedule allows. QT2 athletes have found the official practice swim useful for getting comfortable in the swim skin, handling contact, and sighting in a race-like setting.
- Targeted Hawi recon. Ride the Hawi section if wind handling is a concern.
- Short run recon. See Aliʻi, Palani, and portions of the Queen K so the transitions between environments are familiar.
- One controlled expo visit. Get what you need and leave.
Optional, Depending on the Athlete
- Parade of Nations
- Welcome banquet
- Fun run / underpants run
- Sponsor events
- Long spectator sessions watching pro activities
If an event costs sleep, keeps you on your feet for hours, or disrupts meals, skip it unless it really matters to you.
Race week is not a checklist of Kona experiences. Your first job is still to race well Saturday.
06 / Check-In & Gear Logistics
Know the Flow Before Friday
Kona transition is more controlled than a typical IRONMAN. Recent race procedures are useful for planning now, even though the 2026 details still need to be confirmed.
Race-Morning Flow — Stable Planning Assumptions
- Athletes move through body-marking/tattoo check before transition.
- Bike and run personal-needs bags are dropped before entering transition.
- Transition is effectively an entry-only flow once you begin moving through the system.
- You have full access to the bike, but recent Kona procedures have not allowed normal access to the Bike Gear Bag or Run Gear Bag race morning.
- Pumps and bike technicians have been available inside transition.
- Pre-swim toilets have historically been available outside the controlled transition area near the hotel.
Plan on the bag you check the day before being final. Do not count on fixing it race morning.
- final athlete check-in deadline and location;
- briefing requirements;
- bike and gear check-in windows;
- what may be placed in bike/run personal-needs bags;
- body-marking/tattoo procedures;
- transition opening/closing time;
- gear-bag access rules;
- post-race gear retrieval;
- parking, shuttles, and road-closure instructions.
Training-Safety Note
Current official Kona course information warns athletes against riding south of Kona town during race week. There is no reason to force a full-course recon. If you are going to ride part of the course, prioritize Queen K and especially Kawaihae–Hawi.
07 / Race Morning
Keep Race Morning Under Control
Kona race morning is loud and emotional. You do not need to match that energy at 5:30 a.m.
Breakfast
Use the breakfast you practiced. QT2's traditional race-morning setup is simple carbohydrate, fluid/electrolyte, and a small amount of protein—often applesauce, banana, whey protein, and sports drink—finished about three hours before your swim start. Keep sipping after that and use the planned pre-start gel.
Sunscreen
Apply it before leaving your lodging. Reapply whenever the race offers the opportunity. Kona is not the place to discover a missed patch on your shoulders six hours later.
Swim Staging
- Know the exact 2026 wave staging deadline.
- Give yourself enough time to swim out and get positioned before the start.
- Use the swim-out as your warm-up. There is no need to sprint it.
- Take note of cap colors immediately ahead of and behind your wave.
08 / Swim Course & Execution
Kailua Bay
Swim Course Map
Kailua Bay · 2.4 mi / 3.86 km
The water is very salty and therefore buoyant. Visibility is typically excellent. Small swell and chop can exist even when the bay looks calm from shore. The course is visually simple compared with many open-water swims.
The World Championship Effect
The biggest difference is not the water. It is the field. A swimmer who is normally near the front of an age group may be surrounded by more athletes of similar or greater ability than usual.
- Start where you belong in this field—not where you normally belong locally.
- Expect more contact at the start and turns.
- If swimmers from a later wave come through, let them go. It does not tell you anything useful about your swim.
- If someone catches you decisively, they are swimming a different race. Stay with yours.
- If you catch an earlier cap color early, move through cleanly rather than settling onto slower feet.
- Stay relaxed through the turns; fighting for the inside line usually has poor return on investment.
First 300 m
Get out with purpose, establish space, then settle. The opening five minutes should not feel like a 1500-meter race.
Middle
Tempo, long strokes, purposeful drafting, minimal unnecessary sighting. Because the water is clear, use the swimmers and course infrastructure to reduce head lifting.
Final 200 m
Increase kick progressively. The objective is circulation and readiness for the long transition movement, not sprinting the beach.
Get out of the water feeling like you completed the swim you planned—not like you survived the first event of a championship.
09 / T1
Efficient, Not Frantic
The key transition objective is to reduce the enormous swim-to-bike heart-rate spike rather than extend it.
- Move forward continuously.
- Use freshwater rinse if available and helpful.
- Apply sunscreen.
- Helmet on correctly before touching the bike.
- Get on the bike and settle in.
The first five minutes tell you almost nothing about how your bike legs will feel. Your body is still redistributing blood flow and dealing with the emotional spike of race start.
10 / Bike Course — Segment by Segment
Know the Course Before Race Day
Bike Course Map
Kailua-Kona → Queen K → Kawaihae → Hawi → Kailua-Kona
Bike Elevation Profile
112 mi / 180.2 km · approximately 5,814 ft / 1,772 m of gain
The official Kona route is not simply “Queen K to Hawi and back.” The first and final miles move through a specific in-town sequence before the long highway section begins. That opening sequence matters because the first 10 miles are crowded, exciting, and much too early to know how the bike is going.
Leave transition at Kailua Pier and wait until the designated mount area on Palani Road to get on the bike. Do not try to make up transition time here. Get clipped in cleanly and let the first several minutes be about organization.
What you see: crowds, barriers, athletes everywhere. What it means: your arousal is higher than your actual sustainable bike effort. What to do: settle before you race.
Climb Palani, turn left/north onto Kuakini toward Old Airport Park, then right onto Loloku Street and left through the Kona Commons access road behind Target. These turns come before the course opens up and are easy places to surge around other riders.
Landmark: Kona Commons / Target. Cue: you are still in the settling zone. Eat or drink only when handling is simple.
Turn right onto Makala Boulevard, then right/south onto Queen Kaʻahumanu Highway toward Palani. The Palani descent is designated as a no-pass zone in current official materials because it is short, steep, fast, and crowded. Penalties can be issued for dangerous riding.
There is nothing to gain by forcing this descent for 15 seconds. Brake before the turn, hold line, and let the road come to you.
After the Palani descent, turn left/south onto Kuakini, continue toward the Kahakai Estates turnaround, then return north on Kuakini and climb Palani again.
The crowds and quick direction changes can make this part feel like a short-course race. It is still the first few miles of an IRONMAN. The real bike has not started yet.
Cue: when you turn back up Palani, think “finish settling.”
Turn left/north onto Queen Kaʻahumanu Highway. The visual environment changes quickly: wider road, lava fields, long sightlines, airport infrastructure, and fewer spectators. Once you are here, you finally have room to settle into the ride.
Your job: aero position, fueling rhythm, hydration rhythm, and patience.
The airport is one of the first useful macro-landmarks north of town. Once beyond it, the road feels increasingly exposed and open. The rollers do not look like much, which makes them easy to over-ride.
What you see: long road, modest rollers, black lava, ocean glimpses. What it means: speed may feel cheap. What to do: keep normalized power boring.
As you continue north, Kawaihae becomes the next major geographic landmark. A slow average speed here does not mean the ride is going badly. Wind and rolling terrain can move speed significantly without changing the correct effort.
If the computer is bothering you, stop looking at mph.
At Kawaihae Junction the course turns left toward Kawaihae Harbor for roughly a mile, then turns right/north onto Akoni Pule Highway (Hwy 270). This is where the Hawi section really starts.
Landmark: Kawaihae Harbor. Cue: “new race problem.” Check posture, fueling, and grip before the wind section builds.
The road trends upward toward Hawi through a sequence of rolling quarter- to one-mile hills. Official course materials note grades up to roughly 6%. The physical challenge is not one steep climb; it is the cumulative climb plus crosswind/headwind exposure.
Vegetation and terrain begin to look different as you move north and gain elevation. The visual change is useful: when the road begins feeling less like open lava highway and more like the Kohala district, you are approaching the upper part of the course.
Headwind is virtual gradient. Shift. Hold target. Accept speed.
The Hawi turnaround is an official timing checkpoint. Personal needs has historically been positioned just after the turnaround on the return side. Do not get hung up on whether Hawi feels like the exact midpoint. Handle the turnaround and move on.
If using personal needs: know the bag contents in order. Grab, refill, leave.
This section can produce completely different races from year to year. Tailwind can create huge speed; headwind can make a descent feel absurdly slow. Crosswinds can arrive without much warning. The wind on the way up tells you very little about what you will get on the way back.
Stay aero when it improves stability for you, keep weight distribution calm, and maintain a loose grip. If it is too fast or gusty to fuel safely, eat and drink before the fastest part instead of losing 30 minutes of intake.
After descending from Hawi, turn through the Kawaihae area and climb back toward Queen K. This climb is not the hardest climb of the day on paper, but it arrives after the most mentally demanding bike section.
Stay inside the cap on the return climb and keep the cadence comfortable.
This is where the first half starts showing up. Riders who looked strong outbound may now be sitting up, under-fueled, or fighting the wind. Your race should still look boring.
The airport becomes a psychologically valuable return landmark: once it reappears, you know the long highway portion is beginning to close.
Town may start to feel close here. Keep riding the same plan.
The course leaves Queen K at Makala, returns through the Kona Commons access road and Loloku, then turns south on Kuakini to Palani and continues toward transition. After hours of straight highway, the sudden return of turns, traffic control, and spectators requires attention.
Finish the bike before you celebrate the bike. Stay sharp until dismount.
2025 Bike Aid-Station Baseline — Verify for 2026
The most recent published Kona guide placed full bike aid stations at approximately 15.2, 29.4, 37.6, 44.3, 53.4, 59.4, 74.3, 85.0, 97.6, and 103.4 miles. Use those distances now only to model bottle capacity and fueling windows. Rebuild the final carry plan when the 2026 guide confirms station locations and products.
11 / Bike Pacing
Keep the Effort Even
QT2's traditional Kona HR pattern is a shallow U: elevated out of the swim, settling early on the bike, steady through the middle, then gradually rising as heat and fatigue build.
Use HR as Information
Expect HR to run somewhat higher than it would in a cool race. Still, a high number is not automatically okay. Read it alongside power, RPE, thirst, cooling, focus, and your stomach.
| Signal | Likely Meaning | Response |
|---|---|---|
| HR modestly higher, power stable, RPE controlled | Expected heat/cardio drift | Continue plan; stay on cooling/hydration. |
| HR rising, power falling, RPE rising | Heat, dehydration, excessive early cost, or underfueling | Back off; cool; hydrate; solve before forcing power. |
| Power high, HR normal, RPE easy early | Adrenaline / fresh legs can mask cost | Stay inside cap anyway. |
| Speed low into the wind | Probably wind, not fitness | Ignore mph. |
Power Principles
- Keep opening power clearly under control.
- Meter power evenly on flats and gradual rollers.
- Allow only modest, preplanned rises on climbs.
- Avoid sustained spikes into headwind.
- There is no speed to make up after a slow section.
- Use aero position as free speed whenever conditions are safe.
The bike only works if you can still run afterward.
12 / Kona Wind Strategy
Ride the Wind, Do Not Fight It
Kona wind can change direction and strength across the course and during the day. A headwind to Hawi does not guarantee a tailwind home. Use the forecast as context, not a promise.
Headwind
- Stay aero.
- Use gearing to keep cadence and power in the target range.
- Accept lower speed.
- Hold the target instead of muscling into the wind.
Crosswind / Gusts
- Relax the grip. White-knuckling the bars makes the bike twitchier.
- Keep upper body quiet.
- Expect gusts at openings in vegetation and terrain.
- Give other riders more room than usual.
- Use the wheel depth you can actually control.
Tailwind
Once a tailwind has you moving fast, let it. Extra watts buy very little. Take the free speed.
13 / Bike Fueling, Hydration & Cooling
Fueling, Hydration, and Cooling Are Separate Jobs
Keep carbohydrate coming in so the effort stays sustainable.
Support circulation and replace a workable fraction of losses.
Reduce heat storage without asking the gut to absorb every ounce.
Keep these separate in the plan. Know carbohydrate per hour, fluid per hour, sodium per hour, and caffeine timing.
Build the Plan Around the Course
The most recent Kona bike map placed aid stations around miles 15, 29, 38, 44, 53, 59, 74, 85, 98, and 103. There is no station immediately after T1, so leave transition with enough fluid and fuel for the first hour.
The clustering around miles 44–59 matters because it overlaps the approach to and turnaround at Hawi. Use those stations to ensure the athlete reaches the descent with enough fluid/fuel on board rather than postponing intake until the return.
The final stations around miles 85–103 come when heat and fatigue are highest. Use them. What you take there matters to the run.
Current On-Course Product Baseline
Recent Kona materials have used Mortal Hydration and Maurten products, but that is a planning baseline only. Confirm the 2026 exact drink formulation, bottle size, gels, caffeinated gel availability, cola, fruit, and personal-needs rules before finalizing the math.
Cooling by Geography
- Town / first Queen K miles: establish hydration before heat feels urgent.
- Waikoloa → Kawaihae: begin using external water if solar load is building.
- Hawi climb: keep intake steady even when wind occupies attention.
- Hawi descent: make sure you actually eat and drink before or during the descent.
- Queen K return: external cooling becomes increasingly important; use water on body whenever practical.
14 / T2
Get Out Before the Tent Gets Hot
The changing area can be hot and crowded. Know what is in the run bag and the order you want it.
- Rack the bike as required by the 2026 procedure.
- Helmet off only after bike is secured.
- Shoes, socks, race belt, hat/visor, nutrition.
- Sunscreen if available.
- Start cooling immediately once outside.
Decide before the race what you are taking at the first run aid station. It is easy to blow past it on adrenaline.
15 / Run Course — Segment by Segment
Know Where the Run Changes
Run Course Map
Aliʻi Drive → Palani → Queen K → NELHA / Energy Lab → Kailua-Kona
Run Elevation Profile
26.2 mi / 42.2 km · approximately 1,009 ft / 307 m of gain
The current official run route has about 1,009 ft / 307 m of gain. It is not mountainous, but it rolls enough to punish you if you keep forcing the pace.
Leaving T2, the course moves up Palani Road to Kuakini Highway. Forget pace for the first few minutes. Get your legs under you, start cooling, and begin the run fueling plan.
The crowd makes the opening feel easier than it is. Let them pull your mood up, not your pace.
Turn south on Kuakini, right on Hualālai, then left/south onto Aliʻi Drive. The environmental feel changes quickly: more spectators, ocean proximity, and potentially more breeze.
Landmark: the turn onto Aliʻi. Cue: “settle into the marathon.”
The turnaround sits before Pāhoehoe Beach Park. Aliʻi is not flat; it rolls enough that pace can vary. Let pace move with the terrain.
Because Aliʻi feels social and fast, it is easy to run harder than you realize.
If the first 10 km already feels like racing, you are probably going too hard.
After the Aliʻi turnaround, return north, turn onto Hualālai, then left/north on Kuakini. This is the last long stretch with real crowd support before the Queen K.
Stay controlled on the return to town. The hard part is still ahead.
Turn right onto Palani and climb to Queen Kaʻahumanu Highway. Everybody remembers Palani because it is obvious, steep enough to matter, and early enough that you may still feel tempted to run it hard.
Walk if running Palani forces a big HR or power spike. The few seconds you save are not worth the cost.
Landmark: top of Palani / Queen K. Cue: “the marathon changes now.”
Once on the Queen K, spectators thin and the road becomes psychologically broad. The course uses the ocean-side/southbound lanes while heading north. You will recognize some of the bike environment, but now there is no aero speed and very little shelter.
Run power/HR/RPE, not the pace you saw on Aliʻi.
The road continues north toward the Natural Energy Laboratory of Hawaiʻi Authority. The danger here is beginning to “race the Energy Lab” before you have reached it. Stay in the current mile.
Turn left from Queen K onto Kahilihili Drive, then right onto Makako Bay Drive. This is where you enter the Energy Lab. The surrounding industrial/research infrastructure makes it visually distinct from the highway.
What you see: the road finally turns away from Queen K. What it means: the famous section has begun. What to do: make it ordinary.
The course proceeds to the NELHA turnaround, then reverses direction within the complex. The section contains enough directional changes that it is more useful to think “next turn / next station” than “how many miles until Queen K.”
Do not negotiate with the whole marathon. Solve the next five minutes.
Turn right back toward Queen K and then right/south toward town. This is a big decision point. You now know what your body has after the hardest environmental section.
If fueling is good, your mechanics are holding together, and RPE is under control, you can start asking for a little more here.
Now you can begin using athletes ahead of you as targets. Continue taking aid-station cooling even if urgency rises. Late-race athletes often stop doing the boring things because the finish feels close.
Keep doing the boring things while you start racing.
Turn right down Palani. The downhill feels completely different after 20+ miles of running than it did when you climbed it earlier. Shorten stride slightly if needed and avoid excessive braking.
Landmark: bottom of Palani. Cue: “the quiet part is over.”
Turn left on Kuakini, right on Hualālai, then right onto Aliʻi Drive. Once you make the final Aliʻi turn, the tactical race is essentially over.
Look up. Stop calculating. Take the finish.
2025 Run Aid-Station Baseline — Verify for 2026
The most recent published guide placed run stations at approximately 1.3, 2.4, 3.5, 3.9, 5.0, 6.1, 7.4, 8.4, 9.8, 11.2, 12.1, 13.0, 13.9, 14.7, 15.7, 16.8, 17.8, 18.7, 19.7, 20.6, 21.5, 22.9, 24.3, and 25.1 miles. Several gaps exceed a mile. That matters in Kona heat. Finalize whether you carry a handheld/flask only after the 2026 station map is confirmed.
16 / Run Pacing & HR
Run the Effort the Day Allows
Run HR should normally sit above bike HR, but Kona heat can move both numbers around. The heat can raise HR 5–10 bpm relative to cooler races for some athletes. The correct response is not to blindly raise the target. Use HR as a stress gauge alongside pace or power and RPE.
First 3 Miles
- Start slower than excitement wants.
- Let stride settle.
- Begin cooling immediately.
- Ignore pace at first.
Middle Marathon
Use power/HR/RPE to keep metabolic cost stable across rollers. Pace should be allowed to move. If pace slows while the effort is right, let it slow.
Second Half
Only increase effort when the athlete's state supports it: fueling functioning, no escalating heat symptoms, mechanics intact, and RPE appropriate. The second half is where you find out whether there is more to give.
17 / Energy Lab Strategy
Treat the Energy Lab Like Any Other Section
The Energy Lab is hard, but its reputation can make athletes start suffering before they even get there. It arrives after prolonged exposure, it is quiet, it is hot, and it is famous for breaking people. That creates anticipatory stress before the athlete even arrives.
Three Rules
- Do not start worrying about it early. Save the Energy Lab for when you actually get there.
- Shrink the time horizon. Once inside, your planning window may be one aid station.
- Use the exit as a checkpoint. The climb out is where the race can transition from preservation to competition.
18 / Equipment
Choose Equipment You Can Handle
Bike Choice
A triathlon bike is the correct choice for nearly every athlete. Kona contains too much sustained aero riding to give away that advantage.
Wheel Depth
Crosswind control is the limiter. A deeper rear wheel is generally easier to manage than an equally deep front. Lightweight athletes and athletes with limited gust experience should favor control over theoretical aerodynamic gains.
Helmet
Balance aero benefit against cooling and comfort. A rider who repeatedly sits up because of heat or discomfort is not realizing the aero benefit of the helmet anyway.
Gearing
No extreme climbing setup is required, but low enough gearing to keep the Hawi climb and Kawaihae return controlled is useful. Use gearing that lets you keep the cadence comfortable without spiking power.
Goggles
Bring more than one pair. Tinted goggles are useful insurance against glare. Bring a backup pair of goggles.
Run Kit
A visor or light hat can make ice management easier. Test anything designed to hold ice or cooling material before race week.
19A / Local Intelligence
Landmark → Cue → Action
Use the landmarks below as simple decision points. You should not be trying to remember paragraphs while racing.
Stay controlled through the turns. The real bike has not started yet.
Hold line. No passing. No unnecessary risk.
Fuel, hydrate, aero. Stop looking for excitement.
Reset grip and posture, and get ahead on fueling before the wind picks up.
Handle personal needs quickly, then get back to work. There is still a long way to go.
Stay on the plan. Keep riding the plan even when town starts to feel close.
Control pace. Let crowd energy remain emotional, not metabolic.
Switch from crowd-guided running to internal process.
Shrink the time horizon.
If you still have it, this is where you can start racing.
Use the crowd. Maintain mechanics.
Look up and take it in.
19 / Common Kona Mistakes
Most Bad Days Start Early
Everyone seems to be passing, so you surge through town. The bill comes much later.
Average speed looks ugly, so power creeps up. Let the speed be ugly.
By the time you notice the deficit, catching up is hard.
High speed and gusts occupy attention; 20–30 minutes disappear without calories.
If the wheels make you sit up, brake, or tense through every gust, the aero gain is gone.
The first miles feel great. Queen K is where you pay for them.
Heat drift is real, but so are dehydration and over-pacing. Read the whole picture.
Heat management should have been continuous since the bike.
Expo time, events, recon, and social plans still create fatigue, even if TrainingPeaks never sees it.
Kona conditions can make early predictions meaningless. Wait.
20 / Mental Execution
Race Like Yourself
Kona can make athletes feel like they need to race differently just because it is Kona. You do not. Use the same habits and judgment that got you there.
Preload the Responses
- Swim contact: breathe, widen if necessary, restore rhythm.
- Headwind: hold planned effort and accept speed.
- Crosswind: relax grip, create space, ride within skill.
- High HR: assess power, cooling, fluid, RPE, and symptoms before deciding.
- GI distress: reduce intensity, cool, simplify intake, address early.
- Low point: do not make a race-level judgment from a 10-minute feeling.
- Great day: keep waiting. The race will tell you when to spend it.
Something will go differently than you pictured. That is normal.
21 / Spectator / Sherpa Notes
Give Your Crew a Plan
Spectators have good access in town and very little once athletes head north on the Queen K.
Best General Opportunities
- Swim viewing near the seawall / Kailua Pier area if arriving early enough.
- Hot Corner and in-town bike passages before the field heads north.
- Run exit from transition and multiple Aliʻi Drive sightings.
- Finish line.
Plan the Reconnection
Pick a post-finish meeting spot before race day. Tracking helps, but finish-line congestion, gear retrieval, dead phones, and fencing can make “I'll text you” unreliable.
22 / Race-Day Quick Reference

24 / Source Base
Built From QT2 Experience and Current IRONMAN Information
This playbook draws from QT2 Kona materials across the 2022–2025 World Championship cycles, including course-preview webinars, shorter course pieces, and the 2025 QT2 athlete race recap.
Those materials provide the coaching details: how to pace the opening bike, handle Hawi wind, read heat-driven HR, stay on fueling, manage the Energy Lab, and get through race week without wasting energy.
Current IRONMAN materials provide the course layout, distance, and elevation data. Exact 2026 operational details still need to be confirmed when the Athlete Guide is published.
25 / The Kona Rule
Patience Buys Options
Swim under control.
Settle the bike.
Fuel before you are hungry.
Cool before you are hot.
Respect Hawi.
Let the Queen K be slow when the wind says it should be slow.
Run Aliʻi Drive like the marathon has just started. It has.
Take the Energy Lab one piece at a time.
Come out of it ready to decide what is left.
Then go.
Have a great race.
