This marathon plan from Pete Pfitzinger and Scott Douglas is the 18-week, 70-to-85-mile schedule from the 4th edition of Advanced Marathoning. If you've come through one of the book's lower tiers healthy and are wondering whether to step up, the training here is sound: long runs at the center, a second long run midweek, and marathon-pace work that grows into a real test.

Co-author Douglas made a jump like this himself. After years at 70 to 80 miles a week, he aimed for 90 to 100. "At first, all that accomplished was being even more tired," he later wrote. "But after a few months, I adapted." This tier asks for the same kind of jump, with its biggest weeks near 82 miles.

But the step up is a step into running every day, with two runs on many Mondays, lighter weeks that are only slightly lighter, and strength work the book recommends but never schedules. The extra miles suit runners who have already handled big weeks without breaking. For everyone else, they mostly add fatigue.

The plan runs in 4 blocks. The first builds endurance. The second lengthens the hard efforts, adds the first fast repeats, and brings the plan's longest run. The third adds short tune-up races and the longest stretch at marathon pace. The last 3 weeks are the taper.

Before the taper, weekly running sits at about 60 to 82 miles, with a run on every day of the week and, from week 7, two runs on some days.

The book asks for at least 55 miles a week before you start. The first Sunday is a 16- to 17-mile run, so long runs of that length should already feel familiar.

A week with Pfitzinger

Here is a typical week from the middle of the plan.

MONDAY is two short recovery runs, 5 to 6 miles in the morning and 4 in the evening, both slow enough to feel like you're loosening up, not training.

TUESDAY is a steady run of 8 to 10 miles, a little firmer than easy.

WEDNESDAY is a second long run, 14 to 15 miles at a relaxed effort.

THURSDAY is a recovery run of 6 to 7 miles.

FRIDAY is the hard day. Within an 11- to 12-mile run, you hold 35 to 40 minutes at the effort you could race for about an hour, with an easy warm-up before and a cool-down after.

SATURDAY is another recovery run of 6 to 7 miles.

SUNDAY is the long run, 20 to 22 miles at an easy, steady effort.

That's 8 runs over 7 days, close to 80 miles, and no day off. Only Friday is hard in the usual sense. But three runs this week are 11 miles or more, and the week's real work is the distance.

Friday is the session people talk about. Thirty-five minutes at that effort is long enough that the last ten feel like a negotiation: breathing heavy but even, the pace holding only because you keep asking it to.

Saturday decides how the week goes. It's a short, slow run squeezed between Friday's effort and Sunday's 20-plus miles, and it's easy to run it at your normal pace out of habit. The book's test for a recovery run is that you should finish having stored energy, not spent it. Get Saturday right and Sunday is a long run. Get it wrong and Sunday turns into a long day of hanging on.

Then Monday comes, with two more runs on legs that ran 20 miles the day before. If the morning run still feels sluggish by the end, take that seriously. At this mileage, the fatigue you ignore today is the fatigue you'll carry into Friday.

Does it build you up smartly?

Structure5/5

A marathon build has two jobs. It has to keep adding endurance week after week, and as the race gets close, it has to make the running look more like the race. Doing those in sequence, rather than all at once, is the idea behind phased training, and planned shifts in emphasis like these tend to beat training that never changes.

Pfitzinger sequences them well. The first six weeks are about distance, with the hour-long-race effort held to modest doses. The middle block stretches those efforts toward 45 minutes and builds the long run to its peak. The fast repeats wait until week 10, and the biggest marathon-pace run comes in week 13, once the base can carry it. New Zealand coach Arthur Lydiard put the rule plainly in his book Run to the Top: "You must condition the body first so that it can stand the hard fast work." Here, that conditioning is everything before week 10, and it's what lets the faster work land on legs that can take it. Each block is labelled on the calendar, so you always know what the current weeks are for. Every session is written out too, with the kind of run, its distance and how much of it sits at effort.

Does it protect you from injury?

Prevention4/5

Mostly yes. The protections are real, but the plan leaves you exposed at three points.

Several things keep the load in check. Through the week, the hard days are kept apart. Every hard session opens with a warm-up. New kinds of workouts arrive one at a time, never in a week when the mileage also rises. And high mileage, built gradually, tends to go with fewer injuries, not more, though that evidence comes from watching runners rather than from trials.

The first weak point is the lighter weeks. The plan eases off in weeks 6 and 10 by about 10 miles, a small cut at this volume, and both still end with a 15- to 16-mile long run. Weeks 12 and 14 run fewer miles, but each one holds a tune-up race. Load that builds without relief tends to raise the risk of injury and illness, which is why a fixed plan needs real lighter weeks written in. World-class coaches in Norway, in sports such as skiing and rowing, build their seasons that way. "To prevent injuries and illnesses, we always implement a recovery week every 3rd or 4th training week," one of them told researchers. This plan's dips come on about that rhythm, but they're too small to do the same job. After each dip, the plan climbs straight past its previous high. Week 7 is about 28 percent bigger than week 6, and it's also the week the Monday doubles begin. Week 11 climbs by about as much and holds the plan's longest run. Measured against the past month, those climbs stay moderate, but they land on legs that have had only a small break. The race weekends add to it: in weeks 12, 14 and 16, a Saturday race is followed by a 16- to 17-mile run on Sunday.

The second is that there's no day off. From week 1 through week 17, every day has a run, and the first scheduled rest day is an optional one on the Monday of race week. The book lets you swap a recovery run for cross-training, and it caps recovery runs with a heart-rate ceiling. But it's still daily running with nowhere to hide. Early evidence, so far from footballers rather than runners, suggests a lingering ache may raise the odds of an injury that stops you, and a plan with no empty day gives that ache no room to settle.

The third is strength. The book lays out a detailed strength program in a chapter of its own. But the calendar never mentions it, so it competes with seven days of running for time and energy, even though strength training substantially lowers injury risk, more than stretching or balance work alone. Pfitzinger has explained the choice: "Our readers don't have the time to focus on that. And we can't really prioritize it without taking away from the running that's going to be of greater benefit to them." On a plan that fills all 7 days, that means the strength work only happens if you decide in advance where it goes.

What happens when you miss a day?

Flexibility4/5

When a week goes wrong, the book's rule for missed training does most of the work. It turns a stressful question into a simple one, keyed to how many days you lost and how close the race is. It also covers what to do during busy stretches of life, and it tells you to ease into the next few fast sessions after missing some. Every day's distance comes as a range, so a tight day can take the short end. And because the hour-long-race efforts are written in minutes, not miles, a slower runner gets the same dose as a faster one.

But it doesn't rank the runs for a short week. The book says endurance matters most, then the hour-long-race effort, then faster work, then speed. That's a good principle, but there's no list telling you what to drop first when a week only has five free days. And on a calendar that already fills all seven days, a missed run has nowhere to go. Moving it means pushing something else, often into the recovery day that was protecting the long run.

Will it get you ready for race day?

Readiness4/5

Yes, with one gap. The marathon-specific work is where this plan's volume pays off, but the longest run comes earlier than it needs to.

Coaches treat long runs as the heart of marathon training, and this plan has two a week. Early evidence links longer long runs to faster marathon finishes, though no study has tested whether shorter, faster sessions could do the same job. The Sunday run reaches 20 miles in week 7 and peaks at 22 to 24 in week 11, seven weeks before the race. That peak goes past the 20 or so miles most marathon plans settle on, and it lands well before the 2 or 3 weeks out that coaches usually aim for. A second run of 11 to 15 miles sits midweek in nearly every week. By the taper, being on your feet for most of a morning is normal.

The marathon-pace runs grow across the plan, and the last is the one to look forward to: 14 continuous miles at your goal pace inside a 20- to 21-mile run in week 13. It's the plan's truest rehearsal. Somewhere past halfway, goal pace stops feeling like a pace you choose and starts feeling like one you have to hold, and that's exactly the feeling race day will bring.

The plan also trains the effort just above that. For most recreational marathoners, marathon pace sits below threshold, the effort you could hold for about an hour, so threshold runs and marathon-pace runs are different kinds of training. This plan gives you both, with threshold work through week 11.

The taper lasts 3 weeks, and race week carries about a third of the plan's biggest week. That's a deep cut from 80-mile weeks, and a taper of that length improves race performance compared with training straight through. It can feel wrong while it's happening. "The first marathon I had to taper, I felt like I was losing fitness," pro marathoner Reid Coolsaet once told a reporter. "But the way I felt in the first part of that marathon, I realized that it worked." Expect the same doubt when your weeks here fall from about 82 miles to 65, then 51. That drop is what the taper is for.

Are the workouts varied enough?

Variety5/5

Yes. The plan trains endurance, the hour-long-race effort, marathon pace and raw speed, each in its own way.

The variety comes in blocks. For the first 9 weeks, the hard days move between two things: long efforts at the hour-long-race effort and long runs with stretches at marathon pace. The only fast running is a few strides and 10- to 12-second hill sprints tacked onto easy runs. From week 10, repeats of 600 meters or a kilometer at your 5K race effort arrive, and from week 12 come three short races of 8K to 15K. If you like a rhythm you can settle into, the first half suits you. If you need change to stay interested, it may feel long.

The mix itself is well chosen. About 88 percent of the running is easy or steady, with clearly hard days set against it, and that mix may build endurance a little better than a lot of medium-hard running. The strides and hill sprints take a few minutes. Strides themselves haven't been tested, but short, explosive work can make each stride cheaper, though the results are mixed. Coach Brad Hudson, whose runners do steep hill sprints year-round, wrote that they "increase the power and efficiency of the stride, enabling the runner to cover more ground with less energy in race circumstances." That's a coach's view, not a test, but the 12-second sprints here take so little time that they're worth doing as written.

The tune-up races are the least certain part. Coaches widely recommend them, though no study has tested whether they change marathon finish time. There's a weak hint that racing experience helps with marathon pacing, and many coaches value them for that, though it's coaching judgment more than proof. Barry Smyth, a Dublin computer scientist who has studied millions of marathon results, writes that "experienced marathoners understand how to avoid hitting the wall." Three short races won't make you an experienced marathoner, but each one is another rehearsal in judging your effort from the start.

The good & bad of training from a book

Advanced Marathoning is good at explaining itself. Each kind of run gets a purpose, an effort range and the mistake runners most often make with it, and effort comes as heart-rate bands. The threshold sessions are set in minutes so runners of different speeds get the same workout. A reader learns why each run is on the calendar, not just what it is.

But to run the plan, you'll be flipping between chapters. The schedule sits in one place, the definitions of each run in another, the strength program in a third, the taper and race-day advice in a fourth, and the pace charts in the appendices. Expect to check the book before a lot of runs, at least for the first few weeks.

Some decisions stay with you. Your goal marathon pace is your call, and the long-run and steady-run paces are set off it, so an over-ambitious goal makes the whole plan harder. The fast repeats ask for your current 5K race effort, but the book has no chart for it. And a printed schedule can't rearrange itself. A missed week, a sick day or a trip all have to be worked around by hand.

Paces also stay fixed unless you update them, though here the plan helps: the three tune-up races in the final weeks are natural points to check your fitness and adjust.

Is it right for you?

You've come through a lower tier of this book healthy

Run it. Your body has already handled big weeks. This tier is the next step: more miles, longer runs, and two runs on some days.

You need a day off each week

Look elsewhere. There's no scheduled rest day until race week.

This is your first marathon

Look elsewhere. The book has no first-marathon plan, and this one asks for at least 55 miles a week before you begin.

You've had a bone or tendon injury in the past year

Think it over. The lighter weeks are only slightly lighter, and the strength work is left off the schedule.

You can't run twice in a day

Think it over. Most Mondays from week 7 to week 15, plus two Thursdays, have a morning and an evening run.

A Saturday race then 16 miles on Sunday sounds like too much

Think it over. Three weekends in the final seven weeks are built that way.

A good alternative with an app

If Pfitzinger's approach makes sense to you but 80-mile weeks don't fit your life, Buena Vida offers its members a plan built on similar ideas: a midweek long run, a weekend long run that builds to 22 miles, hard days kept apart, and marathon-effort running saved for the end.

Frequently asked questions

Do I need the book to run the Pfitzinger 18-week, 70 to 85 mile plan?
Yes. The schedule lists each run's type and distance, but the efforts that go with each type, the heart-rate bands and the pace charts are all in Advanced Marathoning. The calendar alone won't tell you how hard to run.
How much do I need to be running before I start?
The book asks for at least 55 miles a week before this plan. The first week opens with a 16- to 17-mile long run, so you'll also want long runs of about that length already behind you.
How many days a week does this plan run?
Every day. From week 7, most Mondays through week 15 and two Thursdays have a morning and an evening run. The first scheduled rest day is an optional one on the Monday of race week. The book does allow cross-training in place of a recovery run.
Can I use this plan for my first marathon?
No. Advanced Marathoning has no first-marathon plan, and this tier starts from at least 55 miles a week. A plan made for first-timers, with fewer days and fewer miles, will serve you better.
Does the plan include strength training?
The book includes a detailed strength program, but none of it is on the calendar. When to do it, and how to fit it around a run every day, is your decision.
Does the plan have recovery weeks or a taper?
The running dips slightly in weeks 6 and 10, and weeks 12 and 14 are a little lighter but each holds a tune-up race. The real easing off is the 3-week taper at the end.
What happens if I miss training?
The book has a clear rule. Under 10 days missed, pick up the schedule where you are. Between 10 and 20 days, rethink your goal only if the race is less than 8 weeks away. Over 20 days, rethink it either way.
What are the tune-up races?
Short races of 8K to 15K in weeks 12, 14 and 16, each on a Saturday, with a 16- to 17-mile long run the next day. The book leaves the choice of races to you.
