The Complete Marathon Race Day Checklist.

You’ve done the training. Sixteen weeks of long runs, tempo sessions, and early alarms. The fitness is banked and there’s nothing left to add.

What’s left is execution — and execution is where marathons get lost. Not usually to fitness, but to small, avoidable things: the safety pins you forgot, the gels left on the hotel nightstand, the shoes still in the car when the bag drop closed. None of these are hard problems. They’re just easy to forget at 5:30 AM when you’ve slept badly and your stomach is in knots.

This checklist exists so you don’t have to think on race morning. Work through it in order, tick things off, and arrive at the start line with nothing on your mind but running.

One Week Out

The work now is logistical, not physical. Nothing you do in training this week will make you faster on race day, but plenty of things can make you slower.

• Confirm your bib collection window. Many major marathons don’t allow race-day pickup, and some require photo ID or a QR code. Know where, when, and what you need to bring.
• Check the start time and your wave. Wave assignments are often printed on the bib or in your confirmation email.
• Plan your route to the start. Road closures, altered metro services, and shuttle buses are all normal. Work it out now, not on race morning.
• Read the course map and elevation profile. Know where the climbs are, where the aid stations sit, and what mile the crowd thins out.
• Check the mandatory or prohibited items list. Some races ban headphones or restrict bag sizes.
• Start watching the forecast. Not to obsess, but to decide what you’ll wear.
• Do your last hard session early in the week, then let the taper do its job.

Two to Three Days Out

• Shift toward carbohydrate. This isn’t about eating more, it’s about eating differently — roughly 70% of calories from easily digestible carbs like rice, pasta, bread, and potatoes. Don’t stuff yourself the night before; spread it across three days.
• Hydrate steadily. Pale-yellow urine is the simple marker. Drinking litres the night before does nothing except wake you up at 2 AM.
• Avoid anything new. No new restaurants with unfamiliar food, no new supplements, no experimental anything.
• Lay out your kit. Everything you’ll wear and carry, physically laid out where you can see it.
• Charge everything. Watch, phone, headphones if you’re using them.

The Night Before

The goal tonight is to remove every decision from tomorrow morning.

Pin your bib

Pin it to the shirt you’re actually racing in, all four corners, while you’re calm and the light is good. Doing this at 6 AM with cold fingers is a genuinely miserable experience. If your race uses a separate timing chip for your shoe, attach it now too.

Lay out your race outfit

• Shorts or tights
• Race shirt or singlet (with bib attached)
• Sports bra, if applicable
• Socks — the exact pair you’ve tested on long runs
• Shoes — the ones you’ve run in, not the new pair from the expo
• Hat or visor, sunglasses if it’s likely to be bright
• Gloves and arm sleeves if it’s cold at the start
• A throwaway layer for the start corral (an old sweatshirt or a bin bag works)

Pack your gear bag

What goes in your bag drop (or stays with your crew) for after the finish:

• Dry clothes — including a dry shirt and warm layer
• Clean socks and comfortable shoes or sandals
• A towel
• Recovery food and drink you actually like
• Phone charger or power bank
• Any medication you need
• Cash and card
• A plastic bag for wet or sweaty kit

Prepare your fuel

Count out your gels or chews and decide exactly when you’ll take each one. Write the plan on your hand or your bib if it helps. Load them into your pockets, belt, or vest tonight so it’s one less thing to remember.

Set two alarms

One on your phone, one on a watch or clock. Aim to wake 3-4 hours before the gun so you can eat and digest properly.

Then stop

Sleep poorly the night before a marathon and it barely matters — the sleep that counts is the two or three nights before that. Don’t panic if you lie awake. Rest quietly and accept it.

Race Morning

3-4 hours before the start

• Eat your tested breakfast. Whatever you’ve eaten before long runs — toast and jam, porridge, a bagel, a banana. This is not the morning to try the hotel’s full buffet.
• Drink normally. Around 500ml of water or sports drink, then sip as you go.
• Coffee, if that’s your routine. If you always have it, have it. If you never do, today isn’t the day to start.
• Apply anti-chafe products everywhere you know you need them — and a couple of places you think you might. Feet, inner thighs, underarms, nipples, bra line, anywhere a seam sits.

90 minutes before

• Get dressed in the kit you laid out. Double-check the bib is on and the chip is attached.
• Final bathroom stop at your accommodation. The queues at the start are always worse than you expect.
• Head to the start. Build in more buffer than feels necessary. Security checks, bag drop queues, and the walk from the drop to your corral all take longer on race day.

At the start area

• Drop your bag as soon as you arrive — bag drop closes earlier than you think.
• Join the toilet queue immediately. You’ll be glad you did.
• Do a light warm-up if you’re racing for time — 5-10 minutes easy jogging and some strides. If you’re aiming to finish rather than compete, the first few kilometres are your warm-up.
• Get into your corral early. Corrals close, and starting from the wrong wave means fighting through traffic for miles.
• Take a gel 10-15 minutes before the gun if that’s part of your plan.
• Ditch your throwaway layer at the last moment. Most races collect and donate them.

The Race Itself

The checklist gets shorter here, because there’s only really one job: run the plan you made when you were rested and thinking clearly.

The first 10K

Almost every marathon that goes wrong goes wrong here. Adrenaline, fresh legs, crowd noise, and a downhill start combine to make goal pace feel absurdly easy. It isn’t. Every second you bank in the first 10K gets repaid with interest after 30K.

If you’re running with a pacer, sit behind them. If you’re running alone, check your watch more often than feels necessary for the first few kilometres until the pace settles.

Fuelling

• Start fuelling early — around 45-60 minutes in, before you feel like you need it
• Aim for 30-60g of carbohydrate per hour, or more if you’ve trained your gut for it
• Take water with gels, sports drink between them
• Stick to your plan even when you don’t feel hungry
• Slow to a walk through aid stations if it means you actually drink rather than wear it

Aid stations

Know before you arrive what you’re taking. Move to the side of the table you want well in advance. Take from the later tables rather than the first, which are always the most crowded. And if the race is cupless — an increasingly common change — make sure you’re carrying a soft flask or collapsible cup.

Managing the second half

Break the remaining distance into pieces. Next aid station. Next landmark. Next kilometre. The full remaining distance is rarely a helpful thing to think about at 32K.

Expect a rough patch somewhere between 25K and 35K. It’s normal, it usually passes, and knowing it’s coming makes it far easier to ride out.

After the Finish

• Keep walking for 10-15 minutes. Stopping dead is how people faint.
• Collect your medal and whatever’s handed out at the finish.
• Eat and drink within 30 minutes, even if you don’t feel like it. Carbohydrate and protein together.
• Get warm and dry quickly. Body temperature drops fast once you stop, especially in cool weather.
• Collect your bag and change.
• Deal with blisters and chafing before they get worse.
• Message whoever’s waiting on news.

Then write it down

Do this within 48 hours, while it’s still vivid. Your finish time, whether you hit your goal, the weather, how the pacing went, what you ate and when, what worked and what you’d change.

Two years from now you won’t remember any of it unless you’ve recorded it — and the details you capture today are what make your next marathon better. Every race you log is data for the next one.

One Last Thing

Every experienced marathoner has a story about the thing they forgot. The socks. The gels. The bib left on the hotel bed. It happens, and almost none of it is fatal — races have safety pins, aid stations have food, and volunteers are more helpful than you’d expect.

The point of a checklist isn’t perfection. It’s to clear enough small worries out of the way that when the gun goes, you’re free to just run.

You’ve done the training. The rest is logistics.
