First Marathon Checklist: Everything to Do the Week Before

The hardest part of your first marathon is already behind you. Sixteen or eighteen weeks of long runs in the dark, in the rain, on legs that didn't want to cooperate — that's the work, and you've done it. The final week isn't about getting fitter; it's about arriving at the start line rested, fueled, and unflustered. What follows is the exact checklist I walk first-timers through, built around the small decisions that quietly decide whether race morning feels calm or chaotic.

Trust the Taper and Stop Chasing Fitness#

The single biggest mistake I see in the final week is panic training. You feel fresh, your legs are springy for the first time in months, and every instinct screams that you've lost fitness and need one more hard session to "check." You haven't, and you don't.

Fitness is built weeks in advance and banked. Nothing you do in the last seven days will add to it — but plenty can subtract. A hard interval session on Wednesday can leave your legs flat on Sunday. A surprise 15-miler "just to be sure" is how people show up already fatigued.

Here's what the running week should actually look like:

• Early week: One short, easy run of 30 to 40 minutes. Keep it genuinely conversational.
• Midweek: An optional easy run with a few 15- to 20-second strides at goal pace — just enough to remind your legs what quick feels like, never enough to tire them.
• Two days out: A very short shakeout of 15 to 20 minutes, or complete rest. Both are fine.
• The day before: Rest, or a gentle 10-minute jog if sitting still makes you anxious.

That restless, itchy, over-caffeinated feeling of having too much energy? That's the taper working. It means you're ready.

Front-Load Your Fuel#

You don't need to eat a mountain of pasta the night before — in fact, one enormous late dinner is more likely to leave you bloated and sleeping badly than fully topped up. Carbohydrate loading works best spread across the final two to three days.

How to actually do it#

Aim to make carbohydrates the star of every meal from roughly Thursday onward: rice, potatoes, bread, oats, pasta, fruit. You're not adding a huge number of extra calories so much as shifting the balance of your plate toward easy-to-digest carbs and away from very high-fat and very high-fibre foods.

A few practical notes from years of watching people get this wrong:

• Ease off heavy fibre in the final 48 hours. Big salads, beans, and bran are great for training but can leave you needing a bathroom you can't find at mile 6. This is not the week for a dramatic new "clean eating" push.
• Hydrate steadily, not frantically. Sip through the day so your urine runs pale straw-coloured. Drowning yourself in water the morning of does nothing but send you to the portable toilet queue and can dilute your sodium.
• Add a little salt to meals in the last day or two, especially if it's going to be warm.
• Eat nothing new. If you've never had a particular energy gel or pre-race breakfast during training, race week is the worst possible time to audition it.

Plan your race-morning breakfast now, and make it something familiar you can eat three to four hours before the gun — oatmeal, a bagel with honey, toast and banana. Buy those ingredients this week so you're not hunting for them at 5 a.m.

Lay Out and Test Every Piece of Gear#

Do this by Thursday, not Saturday night. Lay everything out on the floor or bed and physically look at it. The classic phrase is "nothing new on race day," and it applies to every single item that touches your body.

The head-to-toe list:

1. Shoes — the pair you've done long runs in, not the pristine ones you bought last week.
2. Socks — the exact ones you trust. Pack a spare pair.
3. Shorts or tights with any pockets you'll actually use.
4. Top, plus a throwaway layer for a cold start (an old long-sleeve or a cheap fleece you won't mind donating at the start).
5. Sports bra, tested over long distance if applicable.
6. Anti-chafe balm — apply generously race morning to thighs, underarms, and anywhere a seam sits. First-timers routinely underestimate this.
7. Hat, sunglasses, or gloves depending on forecast.
8. Watch, charged the night before.
9. Nutrition — the exact number of gels or chews you plan to take, plus one extra.
10. Bib and safety pins, or a race belt.

The pinning ritual#

Pin your bib to your race-day top the night before. Fumbling with four safety pins while adrenaline shakes your hands is a needless stress. If your race uses a timing chip that threads through your shoelaces, attach it now too.

Check the weather midweek and again the night before, then choose your outfit for how you'll feel 10 minutes into running, not how you feel standing at the start. A good rule: if you're slightly cold and a little underdressed while waiting, you've probably got it right.

Sort the Logistics Before Race Morning#

More first marathons are ruined by a missed shuttle or a wrong turn than by anything physical. Solve the boring problems now while you're calm.

• Pick up your bib early if the expo allows it. Never leave packet collection to race morning unless there's genuinely no other option.
• Map your route to the start, including parking or the closest transit stop, and check whether roads close early. Marathons shut down large parts of a city; the road you'd normally drive may be barricaded.
• Know the bag drop. Where is it, when does it close, and what bag are you allowed to use? Many races issue a specific clear bag — pack it the night before.
• Locate the toilets at the start and accept that the queues will be long. Budget 30 to 45 minutes of standing around before you even move.
• Set two alarms, and tell someone to check you're up.
• Screenshot the course map and your goal splits so you're not relying on signal in a crowd.

If friends or family are coming to watch, agree on one or two spectator points and a meeting spot for afterward. Phone networks get overwhelmed near big finish lines, so a pre-agreed "I'll meet you by the blue flag" beats trying to call.

Protect Your Sleep — Especially Two Nights Out#

Almost everyone sleeps badly the night before a first marathon. Nerves, an early alarm, a strange hotel bed — it's normal, and one rough night won't hurt your race. That's exactly why the night that matters most is two nights before. Bank your good sleep on Friday for a Sunday race, and don't panic if Saturday is restless.

Wind things down in the last few days: get to bed at a consistent hour, ease off screens late in the evening, and go gentle on caffeine and alcohol. A glass of wine at a pre-race dinner won't end your race, but a heavy night absolutely can.

If you're travelling to the race, arrive with a day to spare if you possibly can. Sleeping in your own routine the night before beats a late arrival and a 4 a.m. scramble in an unfamiliar city.

Steady the Nerves#

Taper anxiety is real. You'll feel phantom aches, convince yourself you're getting sick, and question whether you trained enough. This is the brain's way of processing a big event, not evidence of a problem. Redirect it: reread your training log and see the work you did. Picture the moments you'll hit — the crowded start, the quiet middle miles, the crowds near the end. Rehearse how you'll respond when it gets hard around mile 20, because it will, and knowing that in advance takes away its power.

Your Final Countdown#

By the time you go to bed the night before, everything should already be decided. Gear laid out and pinned. Breakfast bought. Alarm set. Route known. All that's left is to get to the start and run the race you've spent months earning.

You are more prepared than you feel. Trust the training, work the checklist, and let race morning be the celebration it's meant to be. See you at the finish.
