You will spend four months training for a start line you’ll stand at for maybe ninety seconds before the gun goes off. Somewhere around mile 20, when your legs are done negotiating and your brain is the only thing left doing any work, the thing that gets you to the finish usually isn’t your training plan. It’s whatever reason you had for signing up in the first place. Almost nobody writes that reason down. Write it down.
Why a Letter Before Your First Marathon Matters
Marathon training is long enough that the person who registers is not quite the same person who shows up on race morning. Week one is mostly hope and a little denial. Week fourteen is sore knees, a color-coded spreadsheet, and a much more complicated relationship with the number 26.2. By race week you’ve rehearsed your reasons so many times — for coworkers, for the group chat, for the stranger who asks why you’re limping — that the original version has usually gotten smoothed into something shorter and less true.
This is not a small club you’re joining. The 2025 TCS New York City Marathon set the record for the largest marathon ever run, with 59,226 finishers crossing that particular finish line — topping the previous record of 55,646 set just one year earlier. And by most running-industry estimates, close to half of any given marathon’s field is running the distance for the first time. You are one of a genuinely enormous number of people doing exactly this, for the first time, this year. That doesn’t make your specific reasons less worth writing down. If anything, it’s more reason to—because the version of the story you tell afterward, once you know how it ends, is never quite the version you were actually carrying at mile 20.
A letter written before the race is the only place built to hold the reasons as they actually were — before you know your finish time, before the story gets a tidy ending, before “why I ran” becomes a caption instead of the truth.
When to Write It
- The week you register. The most idealistic version, and worth capturing precisely because of that — before the training has ground any of the optimism down.
- The week of your last long run, right before taper. You’re at peak fitness and, honestly, peak doubt at the same time. That combination doesn’t happen again until the next training block.
- The night before the race. The rawest version — race-morning nerves, whatever’s actually running through your head instead of the calm pre-race routine you told people you’d have.
Since Hold My Letter schedules delivery one month to two years out, the timing that works best is writing during an active training block — registration week or taper week — so the letter can be timed to land race week itself, or a year out for whichever race comes next.
What to Include
- The real reason you signed up. Not the one you give people at work. The actual one — a milestone birthday, a bet, a bad year you wanted to prove something against, a friend who talked you into it at exactly the wrong moment.
- What a hard week of training actually looked like. The 5 a.m. alarms, the run you almost skipped, the week your knee scared you. The spreadsheet won’t remember any of that. You will, if you write it down now.
- What you’re actually afraid of on race day. Not finishing, going out too fast, walking, your family seeing you struggle. Whichever one is real, name it specifically instead of the generic “I’m nervous.”
- The goal you’re chasing, and whether it actually matters. A finish time, a specific bib number, just finishing upright. Be honest about how much of that number is really about you versus about what you think you’re supposed to want.
- Who you want to think about during the race. The person who’s coming to watch, the one who couldn’t make it, the one this race is quietly dedicated to even if you haven’t said so out loud.
- What you want to remember if the day goes sideways. Injury, bad weather, a wall that shows up earlier than mile 20. Write down what you’d want to hear from yourself if this one doesn’t go the way you’re hoping.
- What you want to tell yourself if it goes right. Not just congratulations — something specific about what getting here actually took, so the credit doesn’t evaporate the moment the medal comes off.
Prompts to Get You Started
Pick two or three. You don’t need to answer all of them.
- What was the actual moment you decided to sign up?
- What does your training plan not know about this training block?
- What are you most afraid of on race morning, specifically?
- What would make this race feel worth it, regardless of your finish time?
- Who do you want to be thinking about at mile 20?
- What’s the version of “why I’m running this” you’d never post online?
- What has this training block taught you that has nothing to do with running?
- What do you want to remember about your body right now, before it does this?
- If the race goes badly, what do you want future-you to know anyway?
- What’s one thing you want to do differently for the next one — and how do you know that already, before you’ve even run this one?
How Hold My Letter Makes This Easy
Taper week is not exactly a calm week — there’s gear to lay out, a hotel to confirm, a pasta dinner to plan, and a low hum of nerves running under all of it. The Digital Future Letter is $9: type it at /write in ten minutes between packing your race-day bag and checking the weather for the fourth time, and we print it on cream stationery, seal it with wax, and mail it on whichever date you choose — race week itself, or a year out.
If you’d rather the letter feel like part of the training block instead of one more task squeezed in around it, the Handwritten Future Letter is $19. You write it by hand and mail it to us; we store it sealed and mail the same envelope back, unopened, on your date — the mail-in checklist covers the whole process. If you’re used to logging miles by hand in a paper training plan anyway, a decent pen makes the letter feel like a natural extension of that habit — a TWSBI Eco holds a lot of ink and writes smoothly enough that a full page doesn’t feel like a chore, which matters if you’ve got more to say than you expected.
For the framework behind structuring any letter like this — not just the marathon version — how to write a letter to your future self walks through the full process. If you want a version of this exercise that isn’t tied to a single race day, the gratitude letter to yourself covers similar ground from a different angle. And if you’re writing this after you’ve already crossed the finish line instead of before, the letter about something you survived is the one for that version instead.
Frequently Asked Questions
When should I actually write this letter?
The week you register is the most honest version — before training has worn you down or made you jaded, when the goal is still mostly hope. The week of your last big long run, right before taper, is the more useful one — you’re at peak fitness and peak doubt at the same time, which is exactly the headspace worth capturing. Either works. What matters is writing it before the start line, not after.
What if I don’t finish, or don’t hit my goal time?
Then the letter becomes more interesting, not less. A letter that only gets read if everything goes right isn’t really a letter — it’s a victory lap you wrote in advance. Write down what finishing would mean to you, but also write down what you’d want to hear if the day goes sideways. That’s the version future-you will actually need.
Should the letter arrive before the race or after?
Before, if you want it as a pep talk — timed to land the week of the race, so you’re reading your own reasons back to yourself before you toe the line. After, if you want it as a gut-check — timed for a few weeks or months post-race, once the soreness is gone and you’re deciding whether to sign up for another one. Some people do both: one letter written at registration for race week, a second written the night before for a year out.
Digital or handwritten — which fits this letter better?
The Digital Future Letter ($9) fits if you’re squeezing this in during taper week, between foam rolling and laying out race-morning clothes — type it at holdmyletter.com/write and it still arrives printed and sealed on your date. The Handwritten Future Letter ($19) is worth it if you want the letter itself to feel like part of the training block — something you sat down and wrote by hand, the way you’ve been logging miles by hand in a training plan all along.
What if this isn’t my first marathon?
Everything here still applies — swap “first” for whichever one this is. A fifth marathon has its own version of the same problem: the reasons get quieter each time, buried under splits and PR math. Writing them down before race day matters just as much the fifth time as the first, maybe more, since it’s easier to assume you already know why you’re doing this.
How far out can Hold My Letter schedule the delivery?
Anywhere from one month to two years out. That covers a letter timed for race week during an active training block, or one timed a year out for the anniversary of this race, or your next one.
You will only run this particular first marathon once. Write down why you’re doing it before the training grinds the reason down to a caption.
