Plan at a Glance
Most marathon plans hand you a fixed goal pace and ask you to chase it for 16 weeks. This one hands you a table and asks you to keep recalibrating against the runner you're actually becoming. Every interval on the schedule (marked '@ 10K pace' or '@ marathon pace') routes back to a Target Pace Level number in chapter 4 of the book. As your fitness climbs across the build, you drop the number, and the same workout gets faster.
An intermediate marathon build is a different animal from a first-timer's plan. The runner already knows the distance is possible. The question is how to arrive on race day with usable speed instead of just survived legs. That usually means sitting at 30 to 40 weekly miles before the plan even starts and holding 6 runs a week without breaking. It also means tolerating workouts that mix tempo running (a sustained, comfortably-hard pace) with race-pace miles.
Matt Fitzgerald wrote this one as part of Brain Training for Runners, a book built around the idea that endurance is partly a skill the brain learns. The plan runs 24 weeks across 6 days a week, with the long run climbing to 22 miles three weeks before race day. Strength work sits on Thursdays and Saturdays. It's meant for runners already comfortable at the volume on day one, not a starting point for someone building up to it.
Below is Buena Vida's full review. We score every plan against the same detailed, 31-point benchmark, with each measure rooted in peer-reviewed sports-science research and proven coaching best practices.

Our Review
You're an intermediate marathoner already training six days a week, and you want to arrive on race day with usable speed, not just survived legs. This is one of the most thought-through 24-week builds in print, and it's organized around one mechanism most marathon plans don't carry.
That mechanism is Target Pace Level (TPL), the pacing system at the heart of Brain Training for Runners. Every pace on the schedule routes through Matt Fitzgerald's TPL table in chapter 4: you enter with your current race-equivalent fitness and exit with the actual paces for the week. As you improve across the 24 weeks, you drop the TPL number and the same '@ 10K pace' workout gets faster. You're not chasing a fixed goal pace. You're training to keep up with your own improving fitness, and the plan re-paces itself around that.
Two things to plan around. The schedule reads hot right after the full recovery week. Weeks 17 and 19 rebound straight back to peak training the week after a week off. Your tendons and your legs take the climb in one step instead of two. And the first eight Base weeks load without a cutback. Bank that deeper recovery yourself.
Best for an intermediate runner comfortable at 30 to 40 weekly miles and training six days a week. You'll want to keep the book on the desk for the pace tables and the strength catalog. If you want paces written as numbers on the page, look elsewhere. If you're below a 30-mile base, build up first. This plan assumes you can hold the volume from day one.

Structure
Does the plan build you up smartly?
Mostly. The build runs through four labeled phases, Base into Build 1, Build 2, and Peak, then a one-week taper across 24 weeks. The arc is clean, and each phase reads with a single clear job. Two things keep it short of full marks. The first eight Base weeks climb without a lighter cutback week to absorb them, and week 23 circles back to Base-phase hill repeats and fartlek, those short bursts of faster running, which reads more as a freshening touch than a textbook taper.
-
Prevention
Does the plan protect you from injury?
Not quite, and this is the plan's softest spot. The good pieces are real. Strength work sits on the calendar, every hard day opens with a warm-up and form drills, and recovery sits between the hard sessions. The trouble is how the workload rebounds. Week 16 is a full rest week, then weeks 17 and 19 jump straight back to peak training, which is where injury risk runs highest. The opening eight Base weeks also climb with no scheduled cutback, so you carry that load without a built-in break.
-
Flexibility
What happens when you miss a day?
You will mostly adapt this plan to your week by judgment, because the calendar itself ships almost no playbook. There is no ranked list of which session to protect and no missed-day rule on the schedule. Fitzgerald keeps those rules in chapters 1 and 9 of the book, so without it you have a rigid grid. The one lever the calendar does hand you is the weekly Proprioceptive Cue, a single form focus you carry across the week's runs.
-
Readiness
Will the plan deliver race-day fitness?
This is where the plan pulls ahead of its peers. Race-day readiness gets built three different ways. The long run climbs to 22 miles three weeks out, half-marathon-pace tempo runs sit just under marathon pace from week 17 on, and three tune-up races (a 5K in week 11, a 10K in week 15, a half marathon in week 20) give you live pacing data well before race day. Volume, long runs, and pace work all point at the 26.2.
-
Variety
Are the workouts varied enough?
The workout menu here is as wide as marathon plans get. Hill repetitions, fartleks, and intervals at five different pace levels anchor the faster work, with tempo runs at two paces, progression runs, mixed intervals, and time-trial tune-ups filling out the rest. Each session names its structure, its drills, and its warm-up. Strength also lands on the calendar twice a week, with rotating core and plyometric sets that grow from one early in the plan to three by Peak.
Plan Strengths
- By race week, you'll know goal marathon pace by feel. Half-marathon-pace tempos and a week-18 marathon-pace run let you sit in race rhythm.
- Three tune-up races (5K in week 11, 10K in week 15, half marathon in week 20) give you live pacing data before race day.
- You'll see strength work on the calendar (Thursdays and Saturdays), with rotating core and plyometric sets that grow from one to three across the build.
- Your long run climbs steadily. It hits 12 miles in week 6 and 16 in week 11. Week 17 brings 18, then 20 and 22 in the peak.
- Every week ships a proprioceptive cue: a single form focus you'll carry across the week's runs to refine technique without thinking about it.
- Twenty-four weeks of build means the legs have time to absorb the long-run climb without the rushed feeling of a 16-week plan.
Weaknesses & gaps
- You won't see a pace number on the schedule. Every '@ 10K pace' prescription routes through the TPL tables in chapter 4.
- The week after the full rest in week 16, training rebounds straight to peak load. Weeks 17 and 19 are where your legs are most exposed.
- Through the Base phase, volume climbs steadily with no scheduled cutback, so the load never fully resets in the first eight weeks.
- Strength exercises and missed-workout rules live in the book chapters, not on the calendar. Without the book you have a schedule and no operating manual.
- Week 23 reads as a regeneration block more than a taper, with hill repeats and fartlek bursts sitting just before race week.
What this plan does not give you
The biggest practical limit is the book dependency. Pace prescriptions show up on the calendar as '@ 10K pace' or '@ marathon pace' instead of numbers, so you'll need chapter 4 to translate them every week. The strength exercises are named only on the calendar, with the movements described in chapter 6, and missed-workout rules live in chapters 1 and 9. If you'd rather not keep the book on the desk, this plan will feel half-loaded. Two structural things are worth knowing as you map it onto your calendar. The week after the full recovery week (week 16) rebounds straight to peak load, so weeks 17 and 19 run hot. And week 23 brings hill repeats and fartlek bursts the week before race week. Bank the deeper recovery yourself.
What the science supports
Periodization beats constant-load training
Across 24 weeks, the calendar moves through clear phases. Early weeks build easy aerobic miles, the middle months layer in faster work, and the final stretch tapers (reduced volume in the days before the race). The long run climbs from 12 miles in week 6 to 22 by the peak, then steps back. Research on trained runners finds that this kind of phase-based build outperforms holding the same load week after week.

Long runs are essential for marathon
The Saturday long run is the spine of this build. It grows from 12 miles in week 6 to 16 in week 11 and 18 in week 17. The peak weeks reach 20 and 22. That progression sits in the two-and-a-half to three-hour range research describes as the window where marathon-specific durability adaptations show up. Shorter, harder sessions cannot stand in for that time on feet.

Race-pace specificity hinges on physiology
Every fast prescription routes through Matt Fitzgerald's Target Pace Level table, so the paces on your schedule are pinned to current fitness rather than goal time. Half-marathon-pace tempo work (sustained running at half-marathon effort) lands near the pace your body can hold for about an hour, which is where research says pace-specific gains actually come from. A dedicated marathon-pace run in week 18 then locks in goal rhythm.

Tune-up races sharpen pacing skill
Three tune-up races punctuate the build: a 5K in week 11 and a 10K in week 15, then a half marathon in week 20. Each one is run at race effort rather than all-out, which is exactly how the research recommends framing them. You arrive at marathon day having rehearsed the rhythm of holding a target pace under pressure, with three live data points on what your current fitness can sustain.
Strength training improves running economy
Strength work sits on the calendar twice a week (Thursdays and Saturdays), with rotating core and plyometric (jumping) sets that grow from one round early to three by the peak. Research finds that this kind of consistent strength habit improves running economy by 2 to 8 percent in trained runners, meaning each mile costs less oxygen at the same pace. That gain stacks on top of the running miles themselves.
