Plan at a Glance
Pete Pfitzinger ran the marathon for the US at the 1984 and 1988 Olympics, finishing as the top American both times. He co-wrote this method with running journalist Scott Douglas around one stubborn idea. The workout most marathon plans treat as optional, the long-ish run in the middle of the week, is what separates a finisher from a racer. Their book Advanced Marathoning has become one of the most cited training manuals in print, and the schedules inside it have outlasted three editions.
Marathon training at 55 to 70 miles a week sits in a particular zone. It's past the territory of a first-marathon plan, where the goal is just to reach the start line healthy. At this volume the limiting factor stops being your lungs and starts being how well your legs absorb the work. The costliest mistake is too much hard running. Easy days have to stay easy so threshold work (running at a pace you could just barely hold for an hour) and long runs can land cleanly.
The schedule runs eighteen weeks at six running days a week and peaks near 67 miles. Five blocks step you through endurance, lactate-threshold work, race-specific prep, taper, and recovery. It's written for runners who have already finished a marathon at 40 to 50 miles a week and want a serious next attempt at the distance. The catch: the calendar names workouts but defines none of them, so you keep Advanced Marathoning open beside the plan, not on the shelf after it.
Below is the full Buena Vida review. Every plan is held to the same detailed, 31-point benchmark, with each measure traced back to peer-reviewed sports-science research and proven coaching best practices.

Our Review
At 55 to 70 miles a week, you're past the survival math of a first marathon. You're into the part where the race is won or lost on rehearsal. You get an 18-week Pfitzinger build that peaks near 68 miles and rehearses race day more thoroughly than almost anything at this tier.
By the start line you will have run marathon pace three different ways. From week 1 it rides inside your long runs, growing from short touches to a 14-mile block. During race prep you race tune-ups at 8K to 15K, so you meet real competitive effort before it counts. Three days out, a 7-mile dress rehearsal puts 2 miles at goal pace as the last hard work in your legs. You've practiced goal pace inside fitness, fatigue, and competition, not just hoped a number holds.
You build clean around that rehearsal. Your long runs peak at 22 miles in week 11, and you meet 20 again three weeks out. The easy-to-hard split sits near 80/20. Dropback weeks at 6, 10, and 14 let your legs reset before each climb. The gaps live off the calendar. Strength sits in chapter 4 of Advanced Marathoning and never reaches the schedule, and a torn-up week sends you to the book.
This one suits a runner with one or two marathons behind them and a 40 to 50-mile base. You'll want Advanced Marathoning on the desk for the strength and missed-week rules. If you're chasing a first marathon, look elsewhere. If you need every pace and contingency on the page, look elsewhere too.

Structure
Does the plan build you up smartly?
Mostly. The 18 weeks split into five blocks that each carry a distinct job: endurance, lactate-threshold work, race prep, taper, and post-marathon recovery. Lighter dropback weeks land at 6, 10, and 14, and while they do not hit a strict three-weeks-on, one-week-easy pattern, they follow Pfitzinger's arc with intent. You feel the cycle as work, work, work, relief, and the shift between blocks changes the character of the running. The point it gives up is that irregular recovery rhythm, looser than the textbook cadence.
-
Prevention
Does the plan protect you from injury?
Partly. Lighter weeks arrive at sensible intervals, the easy-to-hard balance stays in the safe band, and recovery days even carry short strides so the legs keep a little speed. The headline gap is strength. The calendar never lists a lifting session, even though Pfitzinger devotes a chapter to twice-weekly work, so a runner who follows the schedule exactly does none. The on-page plan also carries no warning signs for a developing injury. Both pieces sit in the book rather than on the days you run.
-
Flexibility
What happens when you miss a day?
Very little of this lives on the calendar, and that is the schedule's soft spot. The page carries no order for which run to protect, no plan for a missed week, and no guidance for the day life crowds your training. Those decisions all sit in chapters 1, 7, and 9 of Advanced Marathoning. The one thing the plan settles cleanly is who should start, since the 55-to-70-mile tier is its own entry bar. Past that, you keep the book open beside the plan, because without it you are guessing when something goes sideways.
-
Readiness
Will the plan deliver race-day fitness?
Mostly, and it is the build's strongest stretch. You climb to a 22-mile long run by week 11 and meet 20 miles again three weeks out, so race distance is no surprise on the day. Marathon pace, the effort you would hold on race day, threads through the long runs from week 1, tune-up races of 8K to 15K land in the race-prep block, and a 7-mile dress rehearsal three days out ties it together. The only soft note is that the long-run peak comes a touch earlier than the strictest timing would put it.
-
Variety
Are the workouts varied enough?
Few marathon plans run a menu this complete. General aerobic, medium-long, recovery, lactate-threshold, and marathon-pace runs each play a defined role inside their block, and so do VO2 max intervals (short, hard reps that lift your top-end engine), tune-up races, and the dress rehearsal. The formats shift as race day nears, with strides early, threshold work through the endurance phase, and intervals saved for race prep. Every hard session is pinned to a race-equivalent pace, so no two stretches of the build ask for the same kind of day.
Plan Strengths
- By race day you'll have run marathon pace three ways: inside long runs from week 1, in tune-up races during race prep, and in a dress rehearsal three days out.
- Long runs build to 22 miles in week 11 and return at 20 miles three weeks out, so race-day distance is rehearsed, not gambled on.
- You'll hold roughly 80% of weekly miles at easy effort. That leaves your one tempo, one marathon-pace run, and one long run landing with real intensity.
- Once you know your goal time, each hard session's race-equivalent pace resolves to a number, so you start running without guessing the target.
- Recovery-day strides and dropback weeks at 6, 10, and 14 keep your leg speed alive and reset your legs before each climb.
- You ease into race day across the last three weeks as volume drops, while the dress rehearsal holds your goal-pace sharpness so you don't go flat.
Weaknesses & gaps
- Strength work never appears on the calendar. You'll slot hip, core, and posterior-chain training in yourself or reach race day under-protected.
- You resolve a missed week from chapter 9 of Advanced Marathoning, not from the schedule in front of you, when illness or travel breaks your routine.
- Pace targets read as tags like 'at marathon race pace,' so you reach for the goal-time conversion before every key workout.
- When life crowds your week, you carry the cut-order priority in your head. The schedule never writes it where you can scan.
- Recovery days name themselves but not the practice. Sleep, fueling, and mobility live off the page or not at all.
What this plan does not give you
The biggest hole on the page is strength. Pfitzinger calls for two strength sessions a week in chapter 4 of the book, but the schedule never lists them. You'll do none unless you add them yourself, and a simple lower-body and core routine after two of your easy runs covers it. The schedule also doesn't tell you what to do when life intervenes. If illness or travel takes out a week, the re-entry rule lives in chapter 9. The practical move is to repeat the prior week rather than chase the missed work. Pace targets read as labels like 'at 15K to half marathon race pace,' which sends you to Appendix A for every key workout. Recovery days name themselves but not the sleep, fueling, and mobility that fill them.
What the science supports
Race-pace specificity hinges on physiology
Marathon goal pace shows up from week 1, not only in race prep. Day 14 places 8 miles at marathon race pace inside a 16-mile run, and day 91 stacks 14 miles at marathon pace into an 18-mile outing. Around those sit lactate-threshold runs of 4 to 7 miles at the harder pace you could hold for about an hour. The pairing matches the research: marathon-pace rehearsal to learn the rhythm, plus slightly faster work to lift the ceiling that rhythm sits beneath.

Periodization beats constant-load training
The 18 weeks split into five named blocks. Endurance runs weeks 1 to 6, lactate threshold plus endurance covers 7 to 12, and race preparation fills 13 to 15. Taper and race close weeks 16 to 18, with post-race recovery after. Lactate threshold means the hardest pace you could hold for roughly an hour. Early weeks stay aerobic with marathon-pace touches, the middle block grows those tempo runs to 7 miles, and race-prep adds 1,000-meter repeats and tune-up races. The phased build outperforms constant-load training in studies.

Easy aerobic volume is the foundation
Roughly 80% of weekly mileage runs at easy or general aerobic effort. Across a 67-mile peak week, only three sessions carry the hard running. They are one tempo run, one marathon-pace run, and one long run. The tempo is the sustained hard effort. The other days are 5 to 6-mile recovery jogs and 9 to 15-mile general aerobic runs at conversational pace. That ratio sits inside the 75 to 85% easy band that distance research recommends as the foundation that lets the few hard sessions do their work.
Haugen et al. 2022; Casado et al. 2022; Tønnessen et al. 2014
Tapering improves race performance by 2-6%
The final three weeks pull volume back without dimming sharpness. Weeks 15 and 16 hold around 55 miles, week 17 cuts to 37, and race week sits near 53 (including the marathon itself). Three days before the start, a 7-mile dress rehearsal carries 2 miles at marathon race pace, keeping the legs sharp into race morning. That progressive volume cut with intensity preserved is the 2 to 6% race-day gain that taper research keeps pointing at.
Keep easy days easy, hard days hard
Key sessions land midweek (Tuesday or Wednesday) and on the weekend long run, with general aerobic and recovery days between. No back-to-back hard days appear across all 18 weeks. A typical week ends with a 12-mile threshold run on Friday, a 5-mile recovery jog Saturday, then a 22-mile long run Sunday. The threshold portion is 7 miles at the hardest pace you could hold for about an hour. Keeping the easy days genuinely easy lets the threshold and long days land at full effort.
