Our Review
Two speed days a week set this apart from every other plan on Hal Higdon's marathon ladder. You run hills or track 800s on Tuesday and a building tempo on Thursday, both on top of Saturday goal-pace runs and Sunday long runs. You pick Advanced 2 over Advanced 1 for that extra hard day, and it is also the thing most likely to undo you if you arrive too soon.
About a quarter of your running here is hard, which is high for a marathon build. The danger is not any single workout. It is the easy days in between. Let your filler runs drift up to a moderate grind and your Tuesday and Thursday work loses its edge, leaving you tired before the Sunday long run. Run the easy days slow enough to hold a conversation and your hard days do their job. Run them medium and you spend 18 weeks in a fatigue hole.
What you get for the effort is rich. You bank three 20-mile long runs, goal-pace runs that grow from five miles to ten, a half marathon tune-up in week 9, and a clean three-week taper. The catch is that no paces appear on the grid, strength never lands on the calendar, and a missed run has no rule on the page. This fits an experienced marathoner who already trains six days and wants speed rather than just a finish, with Marathon: The Ultimate Training Guide kept close for the numbers. If two hard days a week is more than you have handled, drop to Advanced 1. If you have never raced past a half, start lower still.

Structure
Does the plan build you up smartly?
Mileage rises in waves and steps back roughly every third week, so the load never piles up three hard weeks deep before your legs get a breather. You can see the rhythm on the calendar: a climb, another climb, then a lighter week. The arc is gradual and sensible rather than sharply phased, which keeps the build readable and the risk low.
-
Prevention
Does the plan protect you from injury?
Your safety here rests on the wave structure, the easy days, and a warm-up before every hard session. The step-back weeks pull your load down often enough to keep you fresh. Behind the grid, the book carries two full injury chapters and a clear list of overtraining warning signs. You are not left guessing about a niggle or a flat stretch. The one real gap is strength: the book tells you how to lift for durability but never puts a session on your calendar.
-
Flexibility
What happens when you miss a day?
The grid hands you a fixed plan and expects you to run it as printed. No priority order tells you which run to cut on a bad week, and the book's catch-up advice is only the vague rule never to go two days without running. There is no scaling for a runner who starts above or below the assumed fitness. You flex the plan using your own judgment, which suits a seasoned runner but offers little safety net if life gets in the way.
-
Readiness
Will the plan deliver race-day fitness?
This plan points everything at the start line. Three separate 20-mile runs bank the distance. Goal-pace runs stretch from five miles to ten so race effort feels rehearsed, and a half marathon in week 9 gives you a full dress rehearsal under a bib. The three-week taper then peels back volume while keeping a little speed, so you reach race morning rested and sharp rather than flat.
-
Variety
Are the workouts varied enough?
You never run the same week twice. Easy runs, long runs, goal-pace runs, building tempo runs, track 800s, and hill repeats all appear, and the two hard slots rotate among them across the build. Your 800s climb rep by rep from four up to eight, your tempo runs stretch from 30 to 50 minutes, and your hills grow from three to seven. The harder work keeps evolving instead of settling into one shape.
Plan Strengths
- Two hard days a week, Tuesday and Thursday, give you more speed exposure than any other plan on Higdon's ladder. You sharpen across hills, tempo, and the track rather than one gear.
- Your track 800s climb from four reps up to eight and your tempo runs stretch from 30 to 50 minutes. Hills grow three to seven, so the hard work meets you in steps instead of one shock.
- By weeks 11, 13, and 15 you bank three full 20-mile long runs, so race-day distance becomes a habit your legs have rehearsed rather than a leap into the unknown.
- Week 9 drops a real half marathon into the build, a genuine dress rehearsal where you practice race pacing and fueling under a bib before the day that counts.
- Goal-pace runs grow from five miles to ten across the build. By the taper, marathon effort sits in your legs as something familiar, not a pace you meet cold on race day.
- A three-week taper closes the plan, trimming volume while keeping a touch of speed, so you arrive at the line fresh instead of stale or flat.
Weaknesses & gaps
- Running stays roughly a quarter hard, which is steep for a marathon build. Let your easy days creep up to a moderate grind and the two hard days lose their edge while fatigue stacks.
- Coming out of a step-back week, your mileage can jump more than a third in a single week. Those rebound weeks demand a patient head rather than a hard charge.
- None of your actual paces print on the grid. The Tuesday 800s, the Thursday tempo, and the Saturday goal-pace runs stay vague numbers until you pull them from Higdon's book.
- With two speed days already booked, fitting strength is your puzzle to solve. The book covers how to lift, light weight and high reps, but never schedules it, so you find days clear of Tuesday and Thursday yourself.
- Fall behind a session and the grid prints no rule for what to drop or shift. You lean on the book's loose never-two-days-off steer and decide for yourself.
- The plan offers no on-ramp and no scaling. A runner arriving without recent two-day-a-week speed work is exposed to early injury, with nothing on the grid to ease the entry.
What this plan does not give you
The first thing to manage is the intensity load. With two hard days plus a goal-pace run most weeks, your easy runs have to stay genuinely easy, slow enough to talk through, or the hard days lose their point. Paces are the next blank. The grid says four by 800 or 35-minute tempo but never the seconds per mile, so before week 1 you will turn a goal finish time into splits using Higdon's book and a pace calculator. Strength is mentioned in the chapters but never scheduled, so pick two easy days and add a short routine there, kept clear of the Tuesday and Thursday speed work. And there is no catch-up rule on the page; the book's simple advice is to never go two days without running and not to cram missed miles back all at once. Shorten or skip rather than pile up.
What the science supports
Periodization beats constant-load training
This plan moves in waves across 18 weeks. Mileage climbs for two weeks, then steps back to a lighter week, before climbing again toward the week 15 peak near 56 miles. After that the last three weeks taper down to race day. Building in clear phases like this, rather than holding one steady load the whole way, tends to leave runners faster and fresher on race morning.

Easy aerobic volume is the foundation
Even on the hardest Higdon plan, about three-quarters of your weekly running is easy. Those daily three to five mile runs, run slow enough to chat, are not filler. They are the aerobic base, meaning the foundation of slow endurance running, that lets the Tuesday and Thursday speed days actually be hard. Skimp on easy volume and the hard days have nothing to stand on.

Long runs are essential for marathon
Sunday is the long run, and it builds to three separate 20-mile efforts in weeks 11, 13, and 15. Runs this long, well over 90 minutes, teach your body to burn fuel for hours and keep your legs from breaking down late. Shorter, faster sessions cannot stand in for them. Banking the full distance three times is what makes mile 22 on race day feel rehearsed rather than terrifying.

Varied intensity beats steady moderate pace
The two weekly hard slots rotate among hill repeats, building tempo runs, and track 800s rather than repeating one workout. Mixing easy running with clearly hard, varied intervals builds endurance better than grinding at a steady medium-hard pace. The 800s climb from four reps to eight and the tempos stretch from 30 to 50 minutes, so the stimulus keeps changing across the whole build.
Stöggl & Sperlich 2014; Rosenblat et al. 2019; Casado et al. 2022
Tapering improves race performance by 2-6%
The final three weeks cut your running back hard while keeping a little speed in your legs. Volume drops from a 56-mile peak in week 15 toward race week, and the tempo runs shrink from 50 minutes back to 30. A taper like this, easing the load for one or two weeks but not going soft, can make you a few percent faster on race day than charging in tired.
