Plan at a Glance
Most marathon plans assume you arrive rested. This one assumes you raced six weeks ago and want to do it again. Pete Pfitzinger, twice a US Olympic marathoner, devoted an entire chapter of Advanced Marathoning to runners who can't quite leave the distance alone. This calendar is that chapter, written as a six-week schedule that picks up where a marathon left off.
Back-to-back marathon plans are a different problem than first-marathon plans. The base is already there, bruised. The work is to rebuild aerobic load fast enough to be sharp again in six weeks without re-tearing the legs that just covered 26.2. Pfitzinger's answer is to compress the sharpening end of a marathon block into the available window. That end means 5K-pace intervals, a tune-up race, and a long run paired with that race. The marathon you just ran is trusted to carry the threshold and goal-pace work the calendar leaves out.
The schedule runs six weeks at four running days a week, written by Pete Pfitzinger and Scott Douglas, the authors of Advanced Marathoning. It is for an advanced marathoner four to twelve weeks past a recent race. You should be healthy, know your paces, and be willing to keep the book open beside the calendar. Workouts are named (VO2 max, recovery, medium-long) but not defined in plan notes, so the book is part of the plan.
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
You have six weeks between two marathons. That is enough runway for one true rebuild, not a full training block. The calendar in chapter 12 of Advanced Marathoning was written for you, the runner whose legs still carry the previous race. You won't find a cut-order rule on the page, a missed-week re-entry guide, or an in-cycle dropback. Those answers live in the book.
The choice that defines this plan is what it leaves off. You don't run a lactate-threshold workout once across six weeks. You don't see goal marathon pace until a 2-mile dress rehearsal three days before the gun. Pfitzinger isn't skipping that work. He is trusting that your last marathon already laid the threshold and race-pace patterning. Six weeks here is for rebuilding the aerobic engine and sharpening turnover on top of it. You don't train into another marathon. You reload into one.
Use this calendar if you finished a marathon in the past four to twelve weeks, are healthy, and want a focused rebuild into the next race. Look elsewhere if you are starting from a base block rather than a recent marathon. The week-1 mileage and the +54% jump into week 2 will not be safe for you. Look elsewhere if your last race left you sore, sick, or limping. Chapter 9's return-to-running protocol is a better starting point than this schedule's week-1 prescription.

Structure
Does the plan build you up smartly?
Partly. The build is coherent for what it is: Pfitzinger's usual five stages compress into three here, an endurance rebuild into race prep into taper, and every key session arrives fully specified with warm-up, work, and cool-down. Hard days generally sit 48 to 72 hours apart. The structural gaps come from the short window. There is no in-cycle dropback week, because six weeks has no room for one, and week 4 deliberately stacks an 8K to 10K tune-up the day before a 17-mile long run. The shape holds together, but it leans on the rest you brought in from your last race rather than building any new cushion.
-
Prevention
Does the plan protect you from injury?
Partly. About 85 percent of the running sits at recovery or easy aerobic effort, recovery days are named on the schedule, and the harder work is spaced sensibly. The catch is that the early ramp is steep, with the load jumping more than 50 percent from week 1 to week 2, which is far past the usual guidance and only defensible because you arrive on marathon-recovery legs that already hold the base. Strength work is not on the calendar, carried over from your prior build, and there is no injury or illness language anywhere in the plan. The safety of this block rests almost entirely on the race you just finished.
-
Flexibility
What happens when you miss a day?
This plan absorbs almost nothing, by its own design. The single rebuild at the start does the one dropback the six weeks allow, and there is no room for another. The calendar offers no order for which session to cut in a busy week, no rule for re-entering after a missed week, and not even a pace table you can read without opening the book. Those answers all live in chapters of Advanced Marathoning, not on the schedule. When something goes sideways here, you are reading the book rather than adjusting the calendar.
-
Readiness
Will the plan deliver race-day fitness?
Partly, and only under one condition. You reach race day having run one 17-mile long run, one 8K to 10K tune-up race, and a 2-mile dress rehearsal at goal marathon pace, which is enough to race well if your last marathon's mileage and threshold work are still in your legs. The plan trusts that prior race to carry the threshold and goal-pace work it leaves out. Used that way, between two marathons, it works. Picked up cold by a runner without a recent marathon underneath, it would leave real gaps in race-day fitness.
-
Variety
Are the workouts varied enough?
Partly. Seven workout shapes appear on the calendar, from recovery, general aerobic, medium-long, and long runs to VO2 max intervals at 5K effort, a tune-up race, and the marathon-pace dress rehearsal. What is missing is deliberate: the threshold runs and the marathon-pace segments inside long runs, both staples of Pfitzinger's longer builds, are left out here on the assumption your prior cycle already supplied them. The category names also sit on the page without explanation, so the definitions are something you carry over from an earlier Pfitzinger block rather than learn here.
Plan Strengths
- Week 4 stacks an 8K to 10K tune-up on Saturday with a 17-mile long run on Sunday, rehearsing race effort and long-run fatigue in one weekend.
- Three days before the gun, a 2-mile dress rehearsal at goal marathon pace lets you settle shoe choice and fueling under live conditions. It also locks in your pacing.
- Strides on recovery days from week 1 keep neuromuscular sharpness alive while the aerobic system rebuilds.
- Three VO2 max sessions (6 × 800m, 6 × 600m, 3 × 1,600m at 5K effort) spread across weeks 3 through 5 sharpen leg turnover without back-to-back interval days.
- Hard sessions arrive fully specified with warmup, work segment, and cooldown, so you don't need to design any of them on the fly.
Weaknesses & gaps
- Without a recent marathon four to twelve weeks back, week 1's mileage and the +54% jump into week 2 are unsafe, not just aggressive.
- Lactate-threshold runs never appear, so the marathon-relevant adaptation Pfitzinger leans on hardest in longer builds isn't trained inside this build.
- Goal-pace running is limited to a 2-mile dress rehearsal, so race effort isn't threaded through your long runs the way longer builds do it.
- Strength work lives in chapter 4 of Advanced Marathoning. The calendar doesn't slot it, so you'll skip it unless you carve a time.
- Missing a week mid-cycle leaves you guessing. The page carries no cut-order or re-entry rule, so you'll be reading chapter 9 in real time.
What this plan does not give you
The plan leans hard on its companion book and that creates four real gaps. Strength training lives in chapter 4 of Advanced Marathoning but never reaches the calendar. If you want it, schedule the sessions yourself, ideally on the two recovery days. Lactate-threshold work doesn't appear at all in six weeks, so if you felt your threshold slip during the marathon you just ran, this block won't rebuild it before race day. Goal marathon pace shows up only in the three-day-out dress rehearsal, so practice race effort yourself on one of the medium-long runs in weeks 3 or 4. Every key session names a pace (@ 5K race pace, recovery effort) without giving you seconds. Before week 1, sit down with Appendix C and convert each one into a number you can run.
What the science supports
Easy aerobic volume is the foundation
Most of the running on this calendar is easy. Week 1 is four recovery and general-aerobic runs totaling 24 miles, with no hard session at all. Even at the week-4 peak near 59 miles, only one VO2 max session and a tune-up race sit above easy effort. The rest is recovery, general aerobic, and a 17-mile long run held at conversational pace. That easy-aerobic base is what a marathoner's legs are rebuilding from in six weeks.

Polarized training beats threshold-dominated
Roughly 85 percent of the weekly mileage sits at recovery or general-aerobic effort. The hard end is sharply hard, not moderate. It runs three VO2 max sessions at 5K pace: 6 × 800m on day 19, 6 × 600m on day 23, and 3 × 1,600m on day 32. One 8K to 10K tune-up race rounds it out. No lactate-threshold runs sit between the two poles. That separation is what the polarized research keeps measuring against threshold-heavy designs.

Tapering improves race performance by 2-6%
Peak mileage hits about 59 in week 4, drops to 46 in week 5, then race week runs roughly 28 miles before the 26.2 itself. That is a 22 percent step down, then a 39 percent step down, which fits the standard 40 to 60 percent total volume cut. Intensity holds. Three days before the start, a 7-mile dress rehearsal carries 2 miles at marathon pace, so race-pace fitness stays sharp while fatigue clears.
Keep easy days easy, hard days hard
Hard sessions are spaced 48 to 72 hours apart across the build, with recovery runs sitting between them. The week-4 weekend is the one deliberate exception. An 8K to 10K tune-up race on day 27 lands the day before a 17-mile long run, so race-effort fatigue carries straight into a long aerobic effort. Every other hard day owns its own week, and the easy days around it stay genuinely easy.

Varied intensity beats steady moderate pace
Seven workout shapes rotate across six weeks. The three VO2 max sessions never repeat their interval length: 6 × 800m, then 6 × 600m, then 3 × 1,600m, all at 5K race pace. The 8K to 10K tune-up race is its own format, and the 2-mile dress rehearsal at marathon pace is another. Recovery days carry 100-meter strides on six separate dates. No moderate steady-state grinding fills the middle zone.
