Plan at a Glance
If you've said "sub-1:30" out loud to your club, you probably also believe the last few minutes are a willpower problem: hang on harder in the long runs and the time will come. It rarely comes from there. At this level, half-marathon pace usually sits close to threshold, the effort you could hold through a hard 10K, so the runner who gets under the line is the one who knows both paces well.
So the week has two jobs and keeps the rest easy. Tuesday is goal pace in pieces: half-mile repeats at first, then longer ones, until whole miles at race pace feel like a place you know. Thursday is threshold, one unbroken stretch at 10K effort that grows longer through the build while the effort stays put. Saturday is the long run, easy from the first mile to the last. Sunday follows it with a medium-long run on tired legs, and that pair is there to teach the back half of the race. Wednesday is strength. Friday is off.
Here is the part that surprises people. You'll run 13 miles, the whole race distance, easy on a Saturday. The longest unbroken stretch at goal pace before race day is 5.9 miles, under half the race. That is the design. The easy miles carry the distance, the midweek work teaches the pace, and on race morning the two meet.
Come in running about 35 miles across 5 days. The biggest week climbs past 60, with lighter weeks along the way. The moment to watch comes right after the first of those lighter weeks. The miles jump back up, and Thursday brings your first long stretch at goal pace. You'll arrive rested and feeling better than you have in a while, and that feeling is the trap. Hold goal pace and no faster, and let the weekend after it stay easy.
The review below is Buena Vida's full assessment of the plan. We grade every plan against the same detailed, 30-point benchmark. Each measure draws from peer-reviewed sports-science research and proven coaching best practices.

Our Review
When you're a competitive runner with sub-1:30 in reach, the next 12 weeks have to get the hard things right. This plan does, and it's one to follow with confidence. The four phases are clear, cutbacks in weeks 4 and 8 sit inside the build with a real taper after it, all 20 hard sessions carry a warm-up and a stated reason, and no hard session ever lands the day after another. Its engine is two midweek sessions that grow on schedule, goal-pace repeats on Tuesday and a threshold block on Thursday, with easy running around them so both days can be properly hard. Peak volume fits the goal, and race-specific work keeps building right up to the taper.
The gaps are small. The week after the first cutback climbs steeply and brings the first race simulation with it, and the long run rises in uneven steps, with big jumps back up after each cutback. Neither is a reason to look elsewhere. Handle that one week with care, and the rest is a plan you can simply follow.

Structure
Does the plan build you up smartly?
In the right order, with each block building on the one before. A two-week base teaches the weekly rhythm, seven weeks of sharpening grow the reps and threshold blocks, then a two-week taper leads into race week. Shifting the emphasis in phases like this tends to beat holding one load the whole way through.
-
Prevention
Does the plan protect you from injury?
The shape of the week does the heavy lifting. Monday's easy run and the weekend pair stay easy, each of the 20 hard sessions begins with a warm-up, and Wednesday (strength, or rest in race week) always sits between Tuesday's reps and Thursday's session. Keeping easy days easy and hard days hard is a sound default for distance runners, and this plan is built on it. Weeks 4 and 8 are true cutbacks, with the hard days swapped for easy running. They will feel almost too light, yet a lighter week is the simplest way to give your legs relief before the climb resumes. Outside the rebounds from those cutbacks, week-to-week increases stay modest. That gives tendons and bone time to catch up with a heart and lungs that feel ready for more well before the rest of you is. The one soft spot is week 5. Coming off the 29-mile cutback, it jumps to about 50 miles, the sharpest rise of the build against your recent weeks, and Thursday brings the first race simulation, 5.9 miles at goal pace. You'll be rested and eager, the pace will feel easier than it should, and that is exactly when runners go faster than asked. Sharp jumps in load tend to raise injury risk, and many aches that feel like slow wear seem to start right after one. Run Monday's 10 miles truly easy, hold goal pace on Thursday and no faster, and if something starts to ache, shorten Sunday first.

Flexibility
What happens when you miss a day?
You lose very little. The week has an order of importance you can read straight off the calendar. Tuesday's goal-pace reps, Thursday's threshold or race-pace session, and Saturday's long run carry it. Monday's easy run and Sunday's medium-long are the runs to trim when life cuts in, and Wednesday's strength session is the first thing to give when the week gets tight. If you move it, keep it off the day before a hard session. Miss a Tuesday and skip it rather than stacking it onto Wednesday, because keeping hard days apart matters more than catching up. Miss a Thursday and let that one go too. Sliding it to Friday puts a hard run right in front of the long run and spends the rest day that protects it. If you lose most of a week, repeat it rather than jumping ahead, and let the next cutback (week 4 or week 8) bring you to the following block whole.

Readiness
Will the plan deliver race-day fitness?
The distance and the pace both get built in full. The peak week tops out near 62 miles, right where a sub-1:30 goal wants it, and that week's 15-mile long run puts more than the race distance in your legs at an easy effort. Race-specific work keeps building toward the taper. The Tuesday reps lengthen to full miles, the Thursday threshold block reaches its longest, a progression run in week 7 closes at goal pace on tired legs, and two race simulations let you feel the effort before the day. Threshold work and goal-pace work are different kinds of training, and neither has been shown to beat the other, so the plan simply gives you both. Then the taper does what it should. The miles come down over the last three weeks while the Tuesday goal-pace miles stay in. Runners who taper like this tend to race better than those who train straight through. The one small cost is how the long run gets there. It climbs in uneven steps, dropping in each cutback and then jumping back up by several miles the week after, so expect those rebound long runs to feel longer than their distance. The 15 is the one big rehearsal of time on your feet, and the 12 and 10 after it keep the habit without adding load.

Variety
Are the workouts varied enough?
Eight kinds of runs, with a shake-out and strides added in race week. They are easy, long, medium-long, threshold, goal-pace intervals, a progression run, race simulations, and the race itself. The intervals come in four formats across three rep lengths. Reps grow from 0.5 mile to 0.75 mile to a full mile, then drop to 3 reps of a mile in race week as a sharpener. Thursday rotates between threshold, race simulation, and a progression run that steps from easy through tempo to goal pace. Each hard session has a clear reason behind it, so the variety reads as a progression, not a menu.
Workouts

You have decided to chase a number that asks for something specific from you, and the work that follows will respect that. Standing at the start of a block like this has its own feeling, before the legs know what is coming and before the schedule has any weight. Take these opening days at face value. There is no need to be fast yet, only present. The shape of what is being built will start to make sense in your legs by the end of the month, not before.
M 6mi Easy Run
6 miles at conversational pace. Monday is the floor for everything that follows this week, so set it deliberately. Run slow enough that you could carry a sentence through to mile six without dropping it. Tomorrow's intervals only go cleanly when this run leaves your legs fresh, not lightly tenderized.
Tu Intervals: 6×0.5mi @ ½ Marathon
Warm up 2 miles, run 6 × 0.5 mile at goal pace (6:49/mile) with 400 m of easy jogging between, and cool down 2 miles. Each rep should match the one before it. The first rep should feel controlled, almost held back. Most runners open too fast on these early sessions and pay for it on rep 4. Hit the pace by the watch and let the body learn what 6:49/mile feels like. Sensation will catch up over the next month. The job today is repeatability across all 6.
W Strength Training
Th 7.1mi Threshold Run with 4.1mi @ Threshold
1.5-mile warmup, then 4.1 miles continuous at 10K race effort, then a 1.5-mile cooldown. This is your first threshold session of the cycle. Effort feels strong and rhythmic but never lung-locked. If you're gasping by mile two, you're running it as a tempo, not a threshold. The point of these is the duration spent at this effort, not how fast you can hold it. Settle in by mile one and let the effort hold itself. Comfortably hard means a few words at a time, never full sentences.
F Rest
Sa 8mi Long Run
8 miles at fully easy effort. The first long run of the plan. Set the floor here. Easy means easy: a pace where you could keep going past mile eight if the plan asked you to. Most runners start faster than they mean to, so hold back through the opening miles. The long run climbs from here toward 15 miles, with lighter weeks along the way.
Su 5.5mi Medium-Long Run
5.5 miles easy on Sunday, the day after the long run. The medium-long on tired legs is the second half of a single training stress, not a separate run. Keep the pace aerobic. If the first mile feels like cement, that's expected. Let the legs find their rhythm by mile two and run by feel from there.
The aerobic engine is the slow story of the whole build, and the early signs are usually invisible from the inside. Mitochondrial density and capillary growth do not announce themselves. They show up later as a pace that suddenly feels conversational where it used to feel like work. The load right now is modest on purpose, and most of your job is to keep the easy days truly easy so that the harder ones can do theirs. If the easy runs start to feel slow, that is the pace doing its job.
M 7mi Easy Run
7 miles conversational. The easy day grew by a mile, but the pace shouldn't notice. Run it exactly the way you ran the 6-mile easy day, just for longer. Easy mileage does its work when the effort stays exactly the same and the distance grows. Pushing the pace doesn't accelerate that work, it stalls it.
Tu Intervals: 6×0.5mi @ ½ Marathon
6 × 0.5 mile at 6:49/mile with 400 m jogs between, framed by 2 miles of warm-up and 2 of cool-down. The shape repeats on purpose. The body files goal pace away as a known location only after several encounters, and each one makes it more familiar. Aim for splits within 2 seconds of each other across the 6 reps. Run the first rep like you plan to enjoy the last one. The workout was perfect if the last rep matched the first in pace and form.
W Strength Training
Th 8.5mi Threshold Run with 4.5mi @ Threshold
2-mile warmup, 4.5 miles at 10K effort, 2-mile cooldown. The threshold block grows by about half a mile this week. The pace stays exactly where it was last Thursday. What changes is how long you hold it. By the last quarter-mile, the effort should feel earned but not desperate. Sustained efforts like this are practice at holding a hard pace while breathing stays under control. Start the block a touch under the effort you expect to hold, and let the back half come to you.
F Rest
Sa 9mi Long Run
9 miles long run at fully easy effort. The long run grows by about a mile across the week. The fitness comes from the duration, not from how fast you cover it. Run the back half exactly like the front half, no faster.
Su 6mi Medium-Long Run
6 miles easy. Sunday on legs that already remember yesterday. Aerobic the whole way. The second week of running this back-to-back is where the shape starts to feel familiar rather than novel.

Plan Strengths
- Two clean progressions carry the build: goal-pace reps that lengthen at the same pace, and threshold blocks that grow from 4.1 to 6.8 miles at the same effort.
- Easy days stay easy and hard days never touch, so Tuesday and Thursday can be run properly hard.
- Two real cutback weeks in the build, then a taper that drops the miles while keeping goal-pace work in.
- Each hard session, from the first half-mile reps to the race-week 3 x 1 mile sharpener, comes with a warm-up and a note that says what it is for.
- Peak mileage and the 15-mile long run fit a sub-1:30 half without overreaching.
- A wide range of run types and interval formats, with race-specific work that grows toward the race.
Weaknesses & Gaps
- Week 5 climbs steeply out of the first cutback, from about 29 miles to about 50, the sharpest rise of the build.
- The first race simulation (5.9 miles at goal pace) arrives in that same big week, alongside a new, longer Tuesday rep.
- The long run climbs unevenly, with big jumps back up after each cutback week.
What's missing
The plan covers the essentials, so what follows are add-ons you can choose rather than holes to fill. Strides appear once, in the race-week shake-out. They are a low-cost way to practice short, fast running, so if you want more of them, add 4 to 6 strides of about 20 seconds at the end of Monday's easy run from week 3 on, and leave them out of the cutback weeks. If your race has climbs, run part of a Monday or Sunday easy run on a rolling route instead of adding a separate hill session. There is also no tune-up race. No study has tested whether one helps, but as a coaching call, a 10K run at race effort (not all-out) can be useful pacing practice and a real-world check on whether the goal fits. The cleanest place is the Saturday of week 6: race in place of the 12.5-mile long run, turn that Thursday's threshold run into an easy run, and keep Sunday short and easy. You give up one threshold session to do it, so make it the only one.
What the science supports
Shifting training emphasis beats unchanging training
The plan breaks into four distinct phases. Base runs weeks 1 and 2 to establish the five-day rhythm. Sharpen spans weeks 3 through 9, where goal-pace intervals climb from half-mile to full-mile reps and threshold blocks grow from 4.8 to 6.8 miles, peaking with the biggest week, about 62 miles, in week 9. Taper covers weeks 10 and 11 with reduced volume but maintained intensity. Race Week closes the cycle. Shifting the emphasis like this, toward race-specific work as the day nears, tends to beat holding one load throughout.
Filipas et al. 2021; Bradbury et al. 2020; Sandbakk et al. 2025
Polarized training matches or beats threshold-heavy plans
About 80 percent of your weekly mileage runs at conversational pace, where you can hold a sentence through mile 6. The remaining 20 percent splits between two hard sessions per week: goal-pace intervals on Tuesday and threshold work on Thursday (at 10K effort). This clean separation (easy days genuinely easy, hard days clearly hard) is the polarized pattern, which in trials of trained runners matched or beat a steady diet of threshold work.
Stöggl & Sperlich 2014; Kenneally et al. 2018; Silva et al. 2024
Keep easy days easy, hard days hard
Easy runs sit at conversational pace. Hard sessions are either Tuesday's goal-pace intervals (growing from 6x0.5mi to 6x1mi across the cycle) or Thursday's threshold work at 10K effort. No moderate-pace grind. No middle ground between easy and hard. Monday and Saturday carry the longest easy runs (building to 12.5 miles and 15 miles respectively). Trained runners tend to improve more with this kind of separation than with a steady stream of moderate-effort running.
Stöggl & Sperlich 2014; Casado et al. 2022; Kenneally et al. 2018
A real taper sharpens you for race day
Weeks 10 and 11 are the taper. Volume drops from the 62-mile peak: Monday eases to 6.5 miles, and the weekend pair shrinks to 12 and 8 miles, then 10 and 7, all easy. Tuesday's goal-pace mile reps stay at full intensity. Race week holds four short runs, with 3 x 1 mile at goal pace five days out and a shake-out two days before the race. Cutting volume this way, with the intensity kept, improves race performance compared with not tapering.
Sharp running-load jumps raise injury risk
The plan starts at 35 miles per week and builds to 62 by week 9. Week 4 and week 8 are deload weeks, stepping volume back before the next climb. Sharp jumps in running load tend to raise injury risk, most clearly when a single run goes well past your longest of the past month. Here the biggest single step is the 15-mile long run, just 2 miles past the 13 before it. That staged build is how the plan keeps the load in check.
