Plan at a Glance
A sub-1:30 half is usually decided after mile 10. Most runners chasing it already have the speed for the first two-thirds of the race. What slips is goal pace in the last 5K, once the legs stop feeling fresh. This plan is built to fix that, and it does it with patience rather than with faster workouts.
Most Tuesdays you run goal pace in pieces: short reps first, then longer ones, then full miles. Thursdays go longer at threshold, the 10K effort a notch quicker than goal pace. Through the build, every weekend pairs a long Saturday with a medium-long Sunday on tired legs, the closest training gets to the end of a half without racing one. Late in the build, one unbroken block at goal pace serves as the dress rehearsal. Apart from a few strides the day before the race, nothing is faster than 10K effort, and it doesn't need to be.
Between the blocks of work sit three easy weeks with no hard running at all. They will feel like lost time. Run them as written anyway. The biggest week, in the high 60s, leans on them.
You'll run six days a week, with Friday for strength. Bring about 40 miles a week of running into it, along with a recent half within sight of the goal, even if it's several minutes off. Then there's Sunday morning. The legs are stiff from the long run, the first mile shows a slow number on the watch, and the choice is to let it be slow. Make that choice and Tuesday's reps still have something to work with.
Below is Buena Vida's full review of this plan. We hold every plan to our detailed, 30-point benchmark, with each measure pulled from peer-reviewed sports-science research and proven coaching best practices.

Our Review
Stuck just short of your goal, with easy days that drift a little too quick, you may suspect the missing piece is speed. The plan starts from the opposite view: the speed is mostly there, and what goes is goal pace late in the race, which it trains with patience. Goal pace comes most Tuesdays, threshold runs grow on Thursdays, and a cutback week closes each block before the next one starts. The 16-week, six-day shape is what makes that possible: it leaves room for three full blocks before the peak, and it keeps the Sunday medium-long that a five-day week would have to give up. The peak weekend sums it up. 16 miles on Saturday, then 11 on Sunday, most of a half on legs that just ran farther than the race.
The gaps are small. Week 5 brings an 11-mile interval day straight out of the first cutback, longer than any run in the month before. It's the one week to run with real care. The hard days also keep one emphasis from start to peak rather than shifting it. None of it changes the verdict. One thing worth knowing before you start: at the peak, a Tuesday of mile reps puts more goal-pace miles in your legs than the dress rehearsal does. The rehearsal is for confidence. The fitness comes from the Tuesdays.

Structure
Does the plan build you up smartly?
Almost, and the missing piece is a change of emphasis. From base building through the long Sharpen phase, the same pair carries the hard work: goal-pace reps on Tuesday and a threshold run on Thursday. Each block makes them longer rather than handing over to work with a different job. The phases are named and explained as you go, so you always know which part of the build you're in. Nothing is left vague, either: each of the 26 hard sessions spells out its warm-up, main work and cool-down, with a note on its purpose.
-
Prevention
Does the plan protect you from injury?
The week's layout is the main safeguard, and it is a good one. Monday, Wednesday and the Sunday medium-long all run easy, Tuesday's reps and Thursday's threshold run each sit between gentler days, and all 26 hard sessions carry a written warm-up. Volume climbs from about 40 miles to the high 60s in three-week blocks, each closed by a cutback with no hard running. New kinds of hard session arrive in weeks where the volume holds steady, and strength sits on Friday, the one day without running. Easy days tend to drift quick right after the first cutback. That same week brings an 11-mile interval day, after a month that topped out at 9.5 miles. Big jumps in running load tend to raise injury risk, most clearly when one run goes well past your recent longest. That interval day is a small step of that kind, so keep week 5's easy days genuinely slow and look at it first if something starts to ache.

Flexibility
What happens when you miss a day?
The plan bends well. The sessions that matter are clear: Tuesday's goal-pace reps, Thursday's threshold run and Saturday's long run. The Monday and Wednesday easy runs and the Sunday medium-long come next, and they're the first runs to drop when life gets in the way. Friday strength sits below them when the week gets tight. Wednesday's easy run gives a missed Tuesday somewhere to slide. If Tuesday's reps move to Wednesday, make Thursday easy. Don't make up a lost long run by stretching the next one. And if a whole week goes sideways, the next cutback is never more than a few weeks away, so pick the plan up where it is rather than repeating what you missed.

Readiness
Will the plan deliver race-day fitness?
Squarely, from the peak week to the last taper session. The peak week in the high 60s and a longest run of 16 miles both sit well inside what a sub-1:30 half calls for, and the long run passes race distance at the start of the final block. Race-pace work and threshold running do different jobs, and either is a reasonable bet, since no study shows one ahead of the other. The plan doesn't choose: the Tuesday reps and the 9.1-mile race simulation (5.1 miles of it at goal pace) sit beside Thursday's threshold runs. Volume falls over the last three weeks, race week is light, and the mile reps hold through both taper weeks. A structured taper like this improves race performance compared with training straight through.
-
Variety
Are the workouts varied enough?
There's broad variety here, set inside a deliberate rhythm. You'll run eight kinds of runs: easy, long, medium-long, intervals, threshold, progression, race simulation and the race itself. The goal-pace reps change shape across the build (half miles, three-quarter miles, full miles, then short reps in race week), the threshold run grows steadily, and two progression runs teach you to finish faster than you start. Every run names its effort plainly (conversational, goal pace, tempo, 10K effort), so you always know what a day is asking for. The week keeps the same shape most of the way through, and familiar weeks let you see the progress inside them.

16 weeks is enough time to build something real, and that is what you are standing at the front of right now. You signed up to chase a number that does not give itself up easily, and the work that gets you there starts today. This week is not where fitness gets made. It is where the rhythm gets set. Find the easy pace that lets you string 16 weeks together, and let that be the win for now.
M 6mi Easy Run
6 miles at easy aerobic effort, the kind of pace where you could narrate this run to a friend without breaking the sentence. This is the first run of the plan, so let it feel almost too easy. Mondays anchor the week. The easier this one is, the better Tuesday's intervals will go.
Tu Intervals: 6×0.5mi @ ½ Marathon
Warm up 2 miles, run 6 × 0.5 mile at 6:49/mile with a 400 m jog after each, and cool down 2 miles. First harder session of the plan. The reps are short on purpose. The goal is to learn what 6:49/mile feels like before asking anything else of the legs. Hit pace cleanly, recover truly, repeat. 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 6mi Easy Run
6 miles fully easy. The day between your first goal-pace intervals and your first threshold session. The Tuesday work is still in the legs. The temptation will be to push harder than easy because pace feels available. Slow down anyway. Threshold is tomorrow.
Th 6.4mi Threshold Run with 3.4mi @ Threshold
First threshold session. 1.5 mile warmup, 3.4 miles at 10K race effort, 1.5 mile cooldown. Threshold is the effort you could race for about an hour, comfortably hard, conversation in short phrases only. If you can hold full sentences, you're going too easy. Sustained efforts like this sit at the pace you can hold for about an hour, not at goal pace. This session is steady, comfortably hard running, held without surging. Comfortably hard means a few words at a time, never full sentences. The session was a success if the final stretch held pace without the form unraveling.
F Strength Training
Sa 8mi Long Run
8 miles at fully easy effort. First long run of the plan, and the floor everything builds from. Run it slow enough that the last mile feels the same as the first. From here the long run climbs to 16 miles by week 13. Note how the late miles feel compared with the early ones. That information shapes the weeks ahead.
Su 5.5mi Medium-Long Run
5.5 miles on Sunday, the day after the long run. The medium-long on tired legs is the lever that separates this advanced plan from a generic build. Keep the pace fully aerobic. The fatigue is the workout, the pace is just the vehicle.
Underneath the ordinary feel of this week, the legs are growing more tiny blood vessels, and the tendons are slowly getting stiffer and springier. None of that announces itself. The runs will feel like runs. That is the point. The work that sinks in where you cannot feel it yet is the work that holds when the training gets harder.
M 6.5mi Easy Run
6.5 miles at easy aerobic effort. Tuesday's intervals stay at the same 6 by 0.5 mile shape. Today's job is to hand Tuesday a pair of legs that Monday hasn't spent. Most runners drift faster in the back half of an easy Monday without noticing.
Tu Intervals: 6×0.5mi @ ½ Marathon
2 miles to warm up, then 6 × 0.5 mile at 6:49/mile with 400 m of easy jogging between, and 2 miles to cool down. Same shape as the session before. The second exposure to a new pace is usually where the pace stops feeling foreign. Pay attention to where in the rep that shift happens. Repeats break hard running into pieces the body can absorb, building speed without breaking form. If a rep felt easy, hold that restraint. The set is the workout, not the rep.
W 6.5mi Easy Run
6.5 miles, easy effort. Same Wednesday role, slightly more volume. The role doesn't change. By now you should know what conversational pace feels like on Tuesday-tired legs. Trust it. Tomorrow's threshold needs a Wednesday that lets the legs recover.
Th 6.5mi Threshold Run with 3.5mi @ Threshold
1.5 mile warmup, then 3.5 miles at 10K race effort, 1.5 mile cooldown. Same shape as last Thursday with 0.1 mile added to the main block. Threshold should sit at the pace you could hold for a 10K race. If you're talking in full sentences during the work, ease into it harder. The sustained stretch builds the strength to stay smooth when the effort gets uncomfortable. If you finished able to imagine one more mile, the effort was judged right.
F Strength Training
Sa 8.5mi Long Run
8.5 miles long, fully easy effort. It matches the long run before it, with half a mile added. Long runs grow in steps like that most weeks. Run the first mile slower than feels right and the last mile will arrive easier than expected.
Su 6mi Medium-Long Run
6 miles on tired Sunday legs. The Saturday-Sunday pair repeats with both runs slightly longer. The medium-long after a long-run Saturday is one of the most specific demands in the plan. Race day asks for similar work in the final 5K. Easy effort throughout.

Plan Strengths
- A cutback week with no hard running closes each block, a regular breather before the next, bigger one begins.
- Goal pace on most Tuesdays, plus a 9.1-mile race simulation late in the build with 5.1 miles at goal pace.
- A long Saturday paired with a medium-long Sunday on every weekend of the build, training the tired legs of the last 5K.
- Hard days never back to back, and a warm-up written into every hard session.
- A taper that trims volume over three weeks while the mile reps stay on the calendar.
Weaknesses & Gaps
- You'll meet an 11-mile interval day in week 5, straight out of the first cutback and past anything you'll have run in the month before.
- Week after week, Tuesday and Thursday train the same two things, so the build never turns toward a new focus before the peak.
- Built for a runner already handling about 40 miles over six days. Someone coming back from a break, or who runs five days a week, will do better with a plan that starts lower or asks for fewer days.
What's missing
A few things sit outside this plan, and each is easy to add. Strides show up only once, in the shake-out the day before the race. Short fast strides are a cheap way to practice running fast while relaxed, so add 4 to 6 relaxed 20-second strides after the Monday easy run from the second block onward (skip them in cutback weeks if you like). Nothing in the plan asks for hills, so if your race course rolls, move some Saturday long runs onto routes that match it and hold the effort, not the pace, on the climbs. The 9.1-mile race simulation, with 5.1 miles at goal pace, already gives you the race-day rehearsal a tune-up would, so the plan doesn't schedule one. If you want a race on the calendar anyway, run a 10K in place of a Thursday threshold run in the middle block and treat it as pacing practice rather than a test.
What the science supports
Shifting training emphasis beats unchanging training
The plan shapes its build into three three-week blocks of harder work, each followed by a cutback week at week 4, 8 or 12 that drops the hard sessions but keeps all 6 running days. Week 13 then peaks at 67.9 miles before a 2-week taper and race week. Plans that change their training over time tend to do better than ones that hold one load the whole way, and tapering at the end has strong support.
Filipas et al. 2021; Bradbury et al. 2020; Sandbakk et al. 2025
Keep easy days easy, hard days hard
Easy runs stay easy: 5 to 10 miles on Monday and Wednesday at a pace where you could talk to someone without struggle. Meanwhile, Tuesday brings goal-pace intervals and Thursday brings threshold work, each one clearly different from easy. Keeping the easy days truly easy is what leaves room for the hard days to be hard. Trained runners tend to improve more with a split like this than with steady medium efforts, and about 83 percent of this plan's running stays easy.
Stöggl & Sperlich 2014; Casado et al. 2022; Kenneally et al. 2018
A real taper sharpens you for race day
From the 67.9-mile peak in week 13, the taper weeks fall to 53.9 and then 46.4 miles, and race week holds 18.8 miles before the race. Tuesday's 6 by 1 mile at goal pace stays through both taper weeks, and race week keeps a short 5 by 0.4 mile tune-up and a 2-mile threshold touch. Cutting volume by roughly 40 to 60 percent before a race while keeping some speed improves race performance compared with not tapering.
Strength training makes running more efficient
Strength training sits on Friday every week from week 1 through week 15, the one day without a run, and comes off the calendar in race week. A single weekly session adds no aerobic miles. Trained runners who add strength work usually become 2 to 8 percent more efficient, burning less energy at the same pace, a measure called running economy. In the final miles of a half marathon, that efficiency adds up.
Blagrove et al. 2018; Balsalobre-Fernández et al. 2016; Šuc et al. 2022
Threshold or race pace: neither proven better
Thursday's threshold block grows from 3.4 miles in week 1 to 5.4 miles in week 13, always run at 10K effort, with a progression run and a 9.1-mile race simulation taking the slot in weeks 7 and 11. Tuesday holds the goal-pace reps. Threshold work and race-pace work are different kinds of training. For recreational runners no study shows one beats the other, so this plan gives you a steady dose of both.
