At some point you signed up for a marathon. Maybe it was a moment of optimism, a charity commitment, or a bet you've since regretted. Either way, the race is in the diary — and so is the rest of your life: the job, the family, the commute, the evenings that vanish before you've even eaten dinner.

The good news is that training for a marathon around a full life is genuinely possible. The less good news is that most training plans aren't written with your life in mind. They assume you have five or six free mornings a week, a consistent sleep schedule, and nothing more pressing than a long run on Sunday. For most people, that simply isn't the world they live in.

So here's a more honest version of what marathon training actually looks like when you're time-poor — and how to make it work without making yourself miserable.

Three runs a week is enough to get you there

Many traditional plans call for five or six sessions a week. If you can manage that, brilliant. But plenty of people have crossed the marathon finish line on three quality runs a week, and you can too.

The rough shape of a three-run week looks like this: one shorter run (30–45 minutes at an easy pace), one slightly longer midweek effort (45–60 minutes, maybe with a few kilometres at a steadier pace), and a long run at the weekend. That long run is the non-negotiable. It's where your aerobic base gets built, where your legs learn what sustained effort feels like, and where your confidence quietly grows.

Three runs won't give you an elite time. They will give you a finish line, which is what most of us are actually after.

The long run is your anchor — protect it accordingly

When the week gets difficult, the short runs are usually the first to go. That's fine. A missed Tuesday jog won't derail your training. A string of missed long runs will.

Treat the long run like a meeting you can't cancel. Put it in the diary early in the week, not last. If Sunday doesn't work, see whether Saturday morning before the household wakes up does. If you only manage one session in a difficult week, make it this one.

The long run doesn't have to be fast. In fact, it shouldn't be. A pace where you could hold a conversation — slower than you think is "proper" running — is exactly right. The goal is time on your feet, not impressive splits.

What to do when the week falls apart

It will. At least a few times over a sixteen-week build-up, the plan will collide with reality and reality will win. A work deadline, a poorly child, a patch of rotten sleep — any of these can knock out a week's training before Wednesday.

The worst thing you can do is try to cram the missed sessions in at the end of the week, stacking runs on consecutive days to "catch up." That's how niggles happen. Instead, write off the week, keep the long run if at all possible, and start fresh.

One bad week in sixteen is nothing. Two or three bad weeks in a row is worth paying attention to — not as a cause for guilt, but as a signal that either the plan needs adjusting or something in the rest of your life needs attention first.

Build in flexibility before you need it

Rigid plans are written for ideal conditions. Your life isn't ideal, and that's fine — you just need a plan that knows it.

A simple way to build flexibility in: instead of committing to specific days, commit to a weekly structure with moveable parts. You need a short run, a medium run, and a long run each week. Which days those happen on can shift with your schedule. Tuesday didn't work? Thursday will do. Couldn't get out before work? Lunchtime counts. A plan that bends around your week is one you'll stick to. A plan that doesn't is one you'll abandon in week four.

Will Powered is built around exactly this idea — adapting your training week to what's actually happening in your life, rather than telling you what your life should look like.

The bits people forget about

Marathon training isn't just running. The recovery — the sleep, the food, the occasional easy day — is where your body actually adapts. When you're fitting training around work and family, it's easy to treat recovery as optional. It isn't.

You don't need to overhaul your diet or sleep eight perfect hours every night. But it's worth knowing that a run on five hours' sleep after a heavy week at work will feel harder and do less for you than the same run when you're properly rested. If a session feels terrible, it might not be your fitness. It might be everything else.

Likewise, strength work — even just ten minutes of single-leg exercises and hip work a couple of times a week — will do more to keep you injury-free than almost anything else. It's easy to skip because it doesn't feel like "proper" training. Don't.

Getting to the start line is the main job

Experienced marathoners will tell you that the biggest mistake first-timers make is doing too much too soon, getting injured, and not making the start line at all. Your goal for the next sixteen weeks isn't to become a different person. It's to arrive at the start line healthy, rested, and having done enough long runs to know you can finish.

The race itself will take care of the rest. Crowds, adrenaline, and the peculiar magic of race day have carried many an under-prepared person further than their training suggested possible.

Be consistent where you can. Be kind to yourself when you can't. And keep showing up.
