Your final three weeks — rehearsal, pacing & fueling
September 1, 2026 · Hosted by Angela Naeth · Session 2 covers race week
Great full-distance races are not one heroic effort. They are hundreds of small, correct decisions.
Nothing you do between tonight and September 19 will make you fitter. There isn't time — and that's good news. The hard part is behind you.
These three weeks decide whether you get to use the fitness you already have.
Most athletes lose an IRONMAN here — not by under-training, but by arriving tired, un-rehearsed, or with a fueling plan they've never tested.
The full distance is aerobic from start to finish. 75–85% of your training hours are easy — that's what builds the durability to absorb six-plus hours of load.
Sleep, fuelling, stress and life stability come before more volume. If the foundation is cracked, the workouts break you instead of building you.
A session you can repeat next week beats a hero session that wrecks you. If it leaves you trashed for three days, the math doesn't work.
Race day is an expression of training, not an audition for it. You don't earn fitness on race morning. You spend it.
Build the engine. Protect the foundation. Train in repeatable doses. Race what you built.
Every layer rests on the one below, and a weak layer caps everything above it — however good the upper layers look on paper.
Three weeks out, the top floors are finished. You're standing on the second floor — and it's the one nobody trains.
Two athletes can have exactly the same top-end fitness. One holds 90% of it for hours. The other starts unravelling at 76%.
One owns sustainability. The other owns potential. In long-course racing, sustainability wins.
That percentage is why two people can follow the same training plan and have completely different race days — and it's why we don't hand out the same plan twice. It's measurable, and it points straight at what you need next.
This is the first thing we'd look at for your 2027 season. Free zone testing tells us where you sit.
Where you race inside your sustainable range depends on training age, fuelling, durability and recovery history — not on ambition.
| Tier | Who | Race it like |
|---|---|---|
| Very Low | First full distance, or early in your build | A finish-it race. Race the experience, not the time. |
| Low | Solid foundation, second or third full | The lower end of every range. Patience wins. |
| Moderate | Race-ready durability, multi-year base | Mid-range, held honestly for the whole day. |
| High | Highly durable, proven fuelling, years of base | Upper end — and most athletes shouldn't reach here just because one workout suggested they could. |
Train mostly in the lower tiers. Race in the tier you've actually built — not the one you wish you'd built. The athletes who cross out of their tier on race day are the athletes who walk.
The 140.6 doesn't reward your best workout. It rewards your most repeatable hour, hour after hour.
You get an athlete with enormous fitness in training who comes apart through pacing or nutrition. Nothing above them failed. They lost the race in a layer nobody tests.
Don't worry about the labels. The one thing that matters: somewhere in Zone 2 your body shifts from running on fat to running on sugar — and sugar stores are small. That shift is the entire reason fueling isn't optional.
| If you can say… | You're in | Effort |
|---|---|---|
| Full sentences, easily | Zone 1 | 3–4 · lives here |
| Short phrases, 3–5 words | Zone 2 | 5–6 · late, if earned |
| Single words only | Zone 3 | 7–8 · never |
Zones built from a formula, an old race, or a guess will lie to you on race day.
Roughly 10–15 percentage points lower. It looks like a different race — because it is.
Five hours forgives. Ten hours doesn't.
Long sessions shorten dramatically. Intensity is preserved in short race-effort touches — that's what keeps you feeling like an athlete instead of flat.
More mileage now adds nothing and risks everything.
| Session | What it is |
|---|---|
| Dress rehearsal | 2–4 hr ride at race effort + 30–45 min run off it |
| Final long run | 75–90 min with race-effort segments |
| Swim | Normal frequency, shortening. No hero sets. |
| Strength | Normal sessions — on hard days only |
The rehearsal replaces this week's other hard work. And if you're beaten up going into the weekend — it gets deferred, not doubled.
Full race kit. Full fueling. Real effort.
Forcing it in the first mile? You're not at race pace. You're above it.
Athletes drift above easy constantly — because the cost changes before the sensation does. If your easy rides have been secretly moderate all summer, that's why you've been tired.
Green light. Your aerobic system is carrying the work.
Something's talking: fatigue, heat, or under-fueling.
That second pattern isn't a verdict — it's information arriving while you still have three weeks to answer it.
A wetsuit that felt fine for 20 minutes in June can rub your neck raw over 2.4 miles. Test it long enough to find out — and put anti-chafe on before you find out the hard way.
| Session | What it looks like |
|---|---|
| Bike | Mid-length ride, 3–4 × 5 min at race effort |
| Run | 45 min with short race-effort pickups |
| Swim | One open-water session — in race kit |
| Strength | Maintenance touches only |
You'll feel restless. Channel it into preparation, not training.
The data of the past eight to ten months is real. The feelings of the last ten days are noise.
It's the most common quiet mistake at this stage. Training volume drops, the scale creeps, and the temptation is to eat less to "get race weight."
You arrive at the start line under-fuelled and under-recovered — then blame your training. Restricting food during a taper doesn't make you lighter on race day. It makes you flat.
Eat normally or slightly more. Your body is restocking glycogen on purpose — and glycogen is stored with water, so the scale going up is the taper working. Expect it. Ignore it.
Race weight is won over months. It is never won in the final three weeks — it's only lost there.
Race the fitness you built — not the one you wish you'd built. Adjusting the goal isn't failure. It's coaching.
| Where it is | What you do |
|---|---|
| Above the neck sniffles, sore throat, head cold |
Easy sessions only. Cut volume hard, keep moving gently. Most athletes recover fine and race well. |
| Below the neck chest, fever, body aches, gut |
Stop completely. No training until you're symptom-free — then add easy days before anything hard. |
Rest early and lose three days. Train through it and lose three weeks. Nothing you can gain by training sick is worth what you can lose.
Let it go. Arriving healthy beats arriving rehearsed — every single time.
Athletes with one goal have one way to succeed and a hundred ways to fail.
Everything lines up. Weather is kind, the body cooperates, the plan holds. This is the goal you're allowed to want — and the one you must not chase early.
Conditions are ordinary, something goes slightly wrong, you adapt. This is the goal you'll most likely hit — and it should still feel like a great day.
Heat, wind, a stomach that quits, a mechanical. You finish, well inside yourself, and you're proud of it. Define what that looks like now.
The moment A slips away, athletes without a B and a C stop racing — because the only outcome they defined is already gone. Write all three down this week, before your brain is tired and negotiating.
| Miles | What it should feel like |
|---|---|
| 0–30 | "Almost too easy." Heart rate is still high off the swim — go by effort and let it settle. |
| 30–80 | Steady, all-day. Full sentences early, short phrases late. |
| 80–112 | Hold if strong. Protect if tired. Never chase. |
Every surge, every hill taken hard is a withdrawal — and it refills far too slowly at race effort.
| Miles | The job |
|---|---|
| 1–8 | Slower than feels right. Your legs spent hours at a fixed hip angle with almost no impact — the first-mile feel is bad information. |
| 8–18 | Steady, fueled, patient. Walk every aid station so you can actually swallow. |
| 18–26.2 | If you settled and worked, you get to spend it now. |
The race doesn't start until mile 18.
Costs a few seconds a mile. Fuel intact, reserve intact — you take it back later for almost nothing.
This error comes with a refund.
Costs fuel and reserve you can't get back at race intensity — spent while you felt fantastic.
The bill arrives at mile 20.
Bias every early decision toward the easy side. The hard part isn't physical — it's watching people pass you while you feel great. You'll see most of them again.
Against the current. Feels slower than it should.
With the current — to loop two, or the exit.
That slow outbound split is the tide, not your fitness. Account for the current when sighting. Water averages 72°F.
Tailwind. You'll feel extraordinary.
Headwind — on every loop.
Hold your effort. Let your speed float. In the tailwind, bank the ease instead of adding power.
Flat doesn't mean easy — it means no rest.
1. The crowd makes you run faster than you intend — every lap.
2. You'll pass the finish before you're allowed to take it. Have a phrase ready.
Minutes sitting on the table — and the three weeks are exactly when to collect them.
You have bags, not a towel on the ground. Everything you need must be in the right bag — and you'll be tired and stupid when you open it. Label things. Keep it simple.
Transitions are the one place you gain time for free — without spending a single match. But don't sprint them. Calm and correct beats fast and flustered.
The full bag-by-bag packing list is Session 2.
Gut tolerance is trainable — and specific to the effort you'll be at. A plan that works in Zone 1 tells you almost nothing about hour five.
The gut cannot absorb at high heart rates. Pacing protects fueling.
Under-fueling doesn't start as a nutrition mistake. It usually starts as a pacing mistake.
If you arrive at T2 under-fueled, you will not catch up on the run. Body size isn't the driver — gut training is. Build one step per long session.

Do it before the weekend. A fuel plan you haven't rehearsed is a hypothesis, not a plan.
Your own tested fuel is the plan. The course is backup. Practise anything you intend to grab.
Adaptation takes 10–14 days and stops helping 5–7 days out. These two weeks are the window.
Heart rate climbing while pace falls. Cost up, output down. That's heat strain — not lost fitness.
Weigh before and after a 90-min ride, track what you drank. Once cool, once humid — race off the humid number.
| When | Trust | Why |
|---|---|---|
| Flat, fair weather | Pace or power target | Conditions match the plan |
| Wind | Effort — let speed float | The number lies in wind. Your breathing doesn't. |
| Heat building | Heart rate + effort, trim early | The same pace costs more. Don't defend a repriced number. |
| Late, form going | Effort + form | If form breaks, the time goal is gone. Protect the finish. |
Thirty seconds to write down before race day.
Place it on hard days — never on easy days, so easy days stay easy.
Quitting a month ago — or lifting heavy ten days out.
They don't sit in the building at all. They decide how much building work actually gets done.
The load that worked in March produces fatigue without adaptation in June, if the rest of your life changed.
Worn-in beats brand-new. They need mileage before mile 18 asks for them.
Arrive 3–4 days early for domestic travel, more if you're crossing time zones. And book the bike service today — mechanics get slammed in the two weeks before a race and you do not want to be the last call.
