A good marathon training plan does one thing above all else: it gets you to the start line healthy. Not the fittest version of you that ever existed. Not injured from cramming miles. Healthy, rested, and quietly confident that you can cover 26.2 miles because your training already proved it.
This is the marathon training plan I give women who are training for their first marathon, including women in their 40s and 50s who came to running late. It runs 16 weeks, asks for four running days per week, and builds your long run by time instead of distance, because time on your feet is what actually prepares your body, and time caps are what keep older beginners uninjured.
If you can currently run (or run/walk) for about an hour, you can start this plan today.
How this marathon training guide works
Every marathon training guide rests on the same four pillars. Once you understand them, the schedule below stops looking like a wall of numbers and starts looking like a story with a beginning, a middle, and a very good ending.
The long run is the whole point. Once a week, you go longer than you did the week before. That single run teaches your body to burn fat efficiently, toughens your tendons and joints, and teaches your brain that "far" is something you do, not something you fear. Everything else in the week exists to support it. Progress comes in waves, not a straight line. Every fourth week, the schedule drops back down. These cutback weeks are when your body absorbs the training and comes back stronger. Beginners who skip them are the beginners who end up injured in week 10. Easy means easy. Almost every run in this plan happens at a conversational pace. If you can chat in full sentences, you're doing it right. If you're gasping, you're stealing energy from Saturday's long run. There is no prize for fast Tuesdays. The taper is sacred. In the final two weeks, the plan shrinks dramatically. This feels wrong and works beautifully. The fitness is already built. The taper lets your legs show up fresh.One more thing that makes this plan different from most: the long runs are measured in minutes, not miles. A 12 minute per mile runner and a 15 minute per mile runner doing "18 miles" are having wildly different days. Three hours is three hours for everyone. That's fairer, safer, and far more honest for the women we coach.
Are you ready to start training for a marathon?
You don't need to be fast. You don't need to look like a runner. You need a base.
Before week 1 of this plan, you should be able to:
- Run or run/walk for 60 minutes without stopping in dread
- Complete about 3 running days per week comfortably
- Say honestly that you've been running for at least 4 to 6 months
Already run a half? You have a head start, and the section on moving from half marathon to marathon below is written for you.
Note: If you're over 45, carrying extra weight, or managing a health condition, a quick conversation with your doctor before marathon training is smart, not dramatic. Nearly every doctor will say yes. It's still worth hearing.

Here is the full week-by-week marathon training schedule. Long runs and midweek runs are in minutes. Cutback weeks are weeks 4, 8, and 12. The longest run peaks at 3 hours 30 minutes in week 14, then the taper carries you to race day.

How to read this schedule
Every run is easy pace unless your body says otherwise. Conversational effort, always. If a run/walk pattern (say, run 4 minutes, walk 1) gets you through the minutes, that counts fully. Run/walk finishers are marathon finishers. The days can shift. Long run on Sunday instead of Saturday? Rest Wednesday instead of Friday? Fine. Protect two rules only: never stack the long run against another run without a rest or walk day beside it, and never skip a rest day to "catch up." Missed a week? Repeat the last week you completed rather than jumping ahead. The schedule serves you, not the other way around. Why the long run stops at 3 hours 30 minutes. You will not run 26.2 miles in training, and you shouldn't. Beyond roughly three and a half hours, the injury risk of a training run outweighs the fitness it adds, especially for runners over 40. The taper, the crowd, and race day adrenaline reliably carry trained runners the rest of the way. Trust the cap.Tip: Book your marathon before you start week 1. A date on the calendar changes how Tuesday runs feel. Curious what race day might look like time wise? Our guide to the average marathon time for women will reassure you that nobody worth listening to cares about your pace.
What each workout in this marathon training program does
A marathon training program is not a collection of random runs. Each type of day has one job.
Long runs (Saturdays). The cornerstone. Go slower than feels necessary, ideally 60 to 90 seconds per mile slower than you imagine your marathon pace to be. Practice everything on these runs: your fuel, your drinks, your shoes, your sports bra, your podcast queue. Nothing new on race day means everything gets rehearsed now. Midweek runs (Tuesday, Wednesday, Thursday). These maintain your aerobic engine between long runs. Wednesday grows gently over the weeks and becomes your "medium long" day. All conversational. If you're feeling strong from week 9 onward, you may finish the Wednesday run with 10 minutes at your goal marathon effort, but this is optional seasoning, not the meal. Cross training or walking (Sundays). The day after your long run, easy movement helps you recover faster than lying on the couch (tempting as that is). Walking, swimming, gentle cycling, or an easy yoga class all work. The rule: you should finish feeling better than you started. Strength work (twice a week, 20 minutes). Two short sessions, tucked in after Tuesday and Thursday runs, protect your knees and hips more than any gadget you can buy. Squats, lunges, glute bridges, calf raises, a plank. For women over 40 this is not optional extra credit, it's the thing that keeps you training. Our guide to strength training for runners has the full routine. Rest days (Monday and Friday). Rest is training. Muscles rebuild, bones remodel, and motivation refills on the days you don't run. Guarding your rest days is a skill. Practice it.Your weekly marathon training routine
The schedule tells you what to run. Your marathon training routine is everything wrapped around it, and it decides how the plan actually feels.
Sleep is your best recovery tool. Long run mileage on six hours of sleep feels like punishment. Aim for an extra 30 to 60 minutes per night from week 9 onward, when the long runs get serious. Fuel the work. Marathon training is not the time to eat less. Under fueled training leads to exhaustion, injury, and a miserable relationship with the sport. Eat a real carbohydrate based meal or snack before long runs, and practice taking fuel during any run over 75 minutes (a gel, chews, or dried fruit every 30 to 40 minutes). Our guides on what to eat before a run and building a running nutrition plan cover the details. Hydrate and mind your shoes. Carry fluids on runs over an hour, with electrolytes in the heat. And if your shoes will wear out mid plan, buy the new pair by week 6. Race day shoes should have 50 to 100 easy miles on them, never zero.
Marathon training when you're over 45, heavier, or starting late
Most marathon plans on the internet were written with a 28 year old in mind. If that's not you, here's what actually changes, and what doesn't.
Recovery takes longer, so the plan must respect it. That's why this schedule has two full rest days and a walking day every single week, with no exceptions even at peak. If a week still feels like too much, repeat it. Two women can both finish the same marathon with one taking 16 weeks and the other taking 22. Both medals are identical. Run/walk is a strategy, not a compromise. Structured run/walk intervals reduce impact stress dramatically and produce finish times that surprise people. If you're carrying extra weight or your joints complain, make run/walk your default from week 1 rather than a fallback when things hurt. Strength and bone health move up the priority list. After menopause, declining estrogen affects bone density and muscle mass. The twice weekly strength work in this plan directly pushes back against both. So does the impact of running itself, applied gradually. We wrote more about this in our guide to running for women over 50. Niggles get 48 hours, pain gets a professional. Soreness that fades as you warm up is normal. Pain that sharpens during a run, changes your stride, or persists into daily life means stop, rest two days, and see a physio if it's still there. Three days off now beats three months off later.Pacing and race day
You don't need a goal time for your first marathon. "Finish feeling proud" is a complete and honorable goal. But you do need a pacing plan, because the most common first marathon mistake is running the first 10k too fast and paying for it at mile 20.
The rule: the first hour should feel almost embarrassingly easy. If you're using a marathon pace chart to pick a target, choose the conservative number and hold it while fresher runners stream past you early. You'll pass most of them back after mile 18, and it will feel wonderful.
Race week is simple: run little, sleep lots, eat normally with a bit more carbohydrate in the final three days, and lay everything out the night before. Nothing new on race day.
Choosing between marathon training plans
Sixteen weeks and four run days is the sweet spot for most first timers, but marathon training plans come in several shapes, and the right one is the one that fits your life.
If you're a true beginner: this plan, exactly as written, with run/walk from day one if needed. Give yourself the full 16 weeks, or stretch to 20 by repeating cutback weeks. If you're short on days: you can shift Thursday's run to a cross training day and train on three run days. Keep the long run untouchable and expect the midweek runs to matter more. If you've run a marathon before: add 10 minutes at goal marathon effort to the end of Wednesday runs from week 5, and consider one gentle progression run per week. You're past needing a beginner structure, but you never outgrow the long run and the taper.From half marathon to marathon
The half marathon to marathon jump is smaller than it looks, and bigger than it looks, at the same time. Smaller, because if you've finished a half, you already run four days a week and understand long runs. Start this plan at week 5 fitness with confidence.
Bigger, because the marathon punishes what the half forgives: skipped fueling, casual pacing, tired shoes. Treat the runs over two hours as a genuinely new sport, and practice eating on the run every Saturday from week 7 onward. That habit, more than any workout, separates a strong marathon debut from a long, hungry walk home.
Marathon training plan FAQ
How long do you need to prepare for a marathon?
For a first timer with a solid base, a 16 week marathon prep schedule is the sweet spot: long enough to build safely, short enough to stay motivated. If you're starting from your first ever run, think 9 to 12 months total: a couch to 5k, then a half, then this plan. Slower is not failure. Slower is how bodies over 40 win.
What is the best training plan for running a marathon as a beginner?
The best beginner marathon training plan is the one you can actually complete: four run days or fewer, one long run per week, regular cutback weeks, a real taper, and easy pacing throughout. Marathon plans for beginners that promise speed work, doubles, or six run days deliver injuries far more often than they deliver finish lines.
Can I follow a training plan to run a marathon using run/walk intervals?
Absolutely, and for many women it's the smartest choice on the table. Every minute in the schedule above works with run/walk. Pick a pattern (run 4 minutes, walk 1 is a lovely starting point), use it consistently from your first week, and use it on race day too. Tens of thousands of marathoners finish this way every year.
Do marathon running plans need speed work?
Not for a first marathon. A marathon training regime built on easy running, one growing long run, and strength work will carry a beginner to the finish more reliably than anything involving a track. Speed work is a tool for your second marathon, once your body has proven it can handle the distance itself.
What if I miss a week of my marathon training schedule?
Life happens, and the plan bends. Missed up to a week? Repeat the last week you completed and continue; your race is still on. Missed two or more weeks in the second half, especially past week 10? Consider choosing a race 4 to 6 weeks later, or arrive planning generous run/walk. What you should never do is skip ahead to "catch up." The schedule builds on itself, and jumping rungs on this particular ladder is how beginners get hurt.
