Plan at a Glance
You've probably already run goal pace. A few reps of it in a workout, or the first half of your last race before the second half took it back. At this level the pace isn't the mystery. Holding it all the way to the finish, on legs that have been asking for a slower gear since mile 9, is what separates close from under.
This plan works on both halves of that problem. Midweek it rehearses the race. Tuesday is goal-pace repeats that start at half a mile and stretch to full miles. Thursday is a long, steady block at 10K effort, just above race pace, that grows through the build. For a runner chasing a sub-1:30 half, goal pace sits close to threshold, so both sessions train the kind of running race day asks for. The weekend builds the distance to carry it: a Saturday long run, then an easy medium-long on Sunday, on legs that still remember Saturday.
If four days a week sounds light for this goal, look at Thursday. With its warm-up and cool-down, the threshold run grows until it's as long as the race itself, in a week when Saturday's long run is no longer. Thursday and the weekend together are how four running days reach about 50 miles in the biggest week. Monday and Wednesday are strength, and Friday is yours. Come in already running about 30 miles a week.
The hard days will take care of themselves. The day to guard is Sunday. The first mile of the medium-long, legs heavy from Saturday, is when sub-1:30 fitness tells the watch it could go faster. Keep that mile conversational and the rest of the run follows, and next Tuesday's reps start on recovered legs.
Below is the full Buena Vida review. Every plan is held to the same detailed, 30-point benchmark, with each measure traced back to peer-reviewed sports-science research and proven coaching best practices.

Our Review
You're close to a sub-1:30 half and have 4 days a week to get there. This focused, well-built plan makes those 4 days enough. Its backbone is race-specific work that grows on schedule. Goal-pace repeats lengthen from half-mile to mile reps, the Thursday threshold block climbs from 4.6 to 7.9 miles, and late in the build a 9.4-mile run at goal pace asks whether mile 8 of it can still hold the pace of mile 2. Around that, the safety basics are in place: a strength day sits between the two hard days, cutbacks land in weeks 4, 8 and 12, and volume steps down over the final three weeks while a few fast touches stay in. The gaps are real but small. Two of the four runs in a building week are hard, so the easy share runs a little thin and the easy days have to stay truly easy. The hard work also does the same two jobs from the first week to the peak. None of that changes the verdict. Run it, and protect your Sundays.

Structure
Does the plan build you up smartly?
Mostly. The one thing it doesn't do is change what the hard days are for. Goal-pace reps on Tuesday and a threshold run on Thursday start in the opening week and grow longer through the Sharpen phase, with no block where the emphasis shifts. The phases themselves are named and explained as you go, from three weeks of base into the long Sharpen phase and on to race week. Every one of the 25 hard sessions is written out in full, with a warm-up, the main work, a cool-down and a note on what it's for.

Prevention
Does the plan protect you from injury?
Soundly, from the warm-ups to the way the weeks are spaced. All 25 hard sessions start with a warm-up, and Tuesday's reps never touch Thursday's threshold run: Wednesday's strength day splits them, and Friday is free before the weekend. Weekly mileage climbs in modest steps from about 30 to about 50, and you never stack more than three building weeks before a lighter one. New kinds of sessions show up in ordinary weeks rather than your biggest ones, so the first time you meet the progression run or the race simulation, you aren't also meeting a jump in mileage. The one thing to guard is balance, since two of your four runs in a building week are hard. Runners tend to improve more when the easy days stay clearly easy, so keep the Saturday long run and Sunday medium-long conversational.
-
Flexibility
What happens when you miss a day?
Three sessions carry the week (Tuesday's intervals, Thursday's threshold run, Saturday's long run), and everything else can bend around them. Sunday's medium-long comes next, and the Monday and Wednesday strength sessions are the first to give when life gets crowded. In cutback weeks the midweek runs drop a level too. Friday is open, which gives you somewhere to move a missed easy run. Be careful about moving a hard one there, though. A Thursday session pushed to Friday lands right before the long run. If Thursday slips, keep it in the week by letting the lower-priority days give way: shorten or drop Sunday's medium-long, or skip a strength session, rather than stacking hard running on the day before Saturday.

Readiness
Will the plan deliver race-day fitness?
Everything a sub-1:30 asks for is here, and the race-specific work stands out. The plan peaks at about 50 miles a week and a 15-mile long run, solidly inside what a sub-1:30 half calls for, and your long runs reach and pass race distance before the start line. The goal-pace reps and the threshold block both get longer as the build goes on, two progression runs finish at goal pace, and the race simulation puts 9.4 continuous goal-pace miles in your legs. Over the final 3 weeks volume steps down steadily, while race week keeps goal-pace reps and a short threshold touch.

Variety
Are the workouts varied enough?
The range here is wide for a half marathon plan. You'll run eight kinds of session across the plan: easy runs, long runs, medium-longs, intervals, threshold runs, progression runs, a race simulation and the race itself, plus a strides shake-out before race day. The intervals change shape as you go, from half-mile to three-quarter-mile to mile repeats. Each hard session spells out its main work, with a note on what it's for. From week 9 on, Tuesday settles into the same 6 × 1 mile at goal pace week after week. Run it enough times and goal pace stops feeling like a target and starts feeling like a known effort.

16 weeks is a long runway, and that is the point. You picked a goal that does not bend to a short build, and you gave it the room it actually needs. The early weeks may feel under-pitched compared to what your legs already know, and that mismatch is by design. Hold the easy effort for real, even when your watch is telling you to push. The base weeks are the ground everything faster gets built on. Stand in this beginning for a moment before the work picks up.

Tu Intervals: 6×0.5mi @ ½ Marathon
2-mile warmup, then 6 × 0.5 mile at goal pace (6:49/mile) with 400 m recovery jogs, then 2-mile cooldown. First interval session of the plan. The 0.5-mile reps are short enough that the first two feel almost easy. Reps 5 and 6 are where the format starts asking a question. Let the legs find the pace rather than force it. Repeats break hard running into pieces the body can absorb, building speed without breaking form. Run the first rep like you plan to enjoy the last one.
W Strength Training
Th 8.6mi Threshold Run with 4.6mi @ Threshold
2-mile warmup, then 4.6 miles at 10K race effort, then 2-mile cooldown. First threshold of the plan. 10K effort is the effort you could race for about an hour but you can still hold short phrases. The block grows across the build. This is the floor. Sustained efforts like this practice holding a hard pace just short of where breathing becomes the limiter. 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 Rest
Sa 8mi Long Run
8 miles, the first long run of the plan. Conversational pace throughout, slower than feels natural. Long runs grow from here, so this one sets the floor. Legs fit enough for your goal time will want to drift faster. The discipline of holding genuine easy effort on Saturday is what protects Sunday's medium-long. The long run climbs from 8 to 15 miles by week 13.
Su 5.5mi Medium-Long Run
5.5 miles easy on Sunday, on legs that have run yesterday. The medium-long after the long is the architectural piece a 4-day plan uses in place of a fifth run. Conversational pace, no exceptions.
The aerobic engine is doing its slow, unflashy work right now. Mitochondrial density, capillary recruitment, and the small refinements in running economy all move on a clock that has nothing to do with how any individual day feels. The temptation at your fitness level is to push the easy efforts into something more interesting. The changes you want from this phase will not arrive any faster if you do. Let the engine build at its own pace, and stay patient with how little of it shows from the outside.
M Strength Training
Tu 6mi Easy Run
Easy 6 miles at conversational effort. The body doesn't get faster from hard days alone. It gets faster from hard days the body can recover from. Today is the recovery that lets the next harder session go well. Run by feel, not pace. The legs will tell you the right speed.
W Strength Training
Th 8.8mi Threshold Run with 4.8mi @ Threshold
2-mile warmup, then 4.8 miles at 10K effort, then 2-mile cooldown. The block grows by about a fifth of a mile from the previous threshold. The pace should feel familiar in the body even at the new length. This session is steady, comfortably hard running, held without surging. Ease into the effort over the first few minutes rather than starting at full pressure. If you finished able to imagine one more mile, the effort was judged right.
F Rest
Sa 8.5mi Long Run
8.5 miles, half a mile more than the previous long run. Easy effort the whole way. The temptation to test the legs at this distance is real. The discipline is letting the long run stay aerobic so Sunday's medium-long is still possible.
Su 6mi Medium-Long Run
6 miles at easy effort on yesterday's tired legs. Fitness built for the time you're chasing pushes pace down on a medium-long more than any other day. The legs feel ready and the watch confirms it, but the discipline is holding back. Run by effort, not by what the watch says you can do.

Plan Strengths
- Race-specific work grows steadily toward race day: goal-pace reps lengthen from half-mile to mile repeats, the threshold block climbs from 4.6 to 7.9 miles, and a 9.4-mile goal-pace rehearsal comes late in the build.
- The two hard runs each week sit two days apart, each starting with a warm-up.
- Cutback weeks arrive on a steady rhythm through the build, and weekly mileage rises in modest steps.
- Volume steps down over the final three weeks while goal-pace reps and a short threshold run stay in race week.
- A long Thursday plus a Saturday long run and Sunday medium-long get four running days to about 50 miles at the peak.
Weaknesses & Gaps
- The easy share runs a little thin. With two hard sessions in a four-run building week, the easy days carry little margin and have to stay truly easy.
- Every hard week asks for goal-pace reps and a threshold run, so no block of the build changes its emphasis.
- Your legs never meet a hill in 16 weeks, so a rolling course will ask for climbing they haven't practiced.
What's missing
You won't find a single hill session in these 16 weeks. If your race course rolls, take some of the Sunday medium-long onto hilly ground from mid-build on, at the same easy effort, so climbing on tired legs isn't new on race day. Strides show up only once, in the race-week shake-out. They're a cheap way to practice running fast while staying loose. Add 4 to 6 short, relaxed strides after one easy run a week, or fold them into the end of Tuesday's warm-up. There's no tune-up race either. The race simulation covers most of what one would teach, but if you want to rehearse a real start line, swap one mid-build Thursday for a 10K, run it at controlled race effort, and treat it as pacing practice rather than a fitness test.
What the science supports
Shifting training emphasis beats unchanging training
The plan runs in four named phases rather than one flat load. Three weeks of base building settle the routine, then an 11-week Sharpen phase grows the intervals and threshold runs, with cutback weeks at weeks 4, 8 and 12. Week 13 peaks at 50.4 miles and a 15-mile long run, and a one-week taper and race week bring the load down. Changing the training over time like this tends to beat holding it steady, though the edge is small and the exact model matters little.
Filipas et al. 2021; Bradbury et al. 2020; Sandbakk et al. 2025
Mileage alone doesn't measure your load
New kinds of hard session arrive in ordinary weeks. The first progression run comes in week 7 and the race simulation in week 11, each in a week only a few percent bigger than the one before. Weekly mileage alone misses part of how hard you're training, because how fast and hard the miles are run adds stress the total doesn't show. Here new effort never arrives on top of a mileage jump.
Paquette et al. 2020; Fredette et al. 2022; Schuster et al. 2025
Longer long runs go with faster marathons
Long runs build from 8 miles in week 1 to a 15-mile peak in week 13, giving you nearly 2 miles beyond race distance in training. Paired with Sunday's medium-long (up to 10 miles), these back-to-back easy runs teach your legs to find rhythm on accumulated fatigue without needing a fifth running day. The research link comes from marathoners. Longer long runs tend to go with faster finishes there, though no study has tested what shorter, faster sessions could do instead.
Doherty et al. 2020; Fokkema et al. 2020; Toresdahl et al. 2022
A real taper sharpens you for race day
Week 15 drops to 36.3 miles from the 50.4-mile peak, and race week, without the race, holds 19.8 miles. Tuesday's 6 by 1 mile at goal pace stays on the calendar in both weeks. Week 15 adds a progression run that finishes at goal pace, and race week keeps a 3.3-mile threshold touch and a Friday shake-out with strides. Cutting volume while keeping some speed improves race performance compared with not tapering.
Two strength sessions a week is enough
Strength sits on Monday and Wednesday in each of the first 15 weeks, cutback weeks and the taper included, and comes off the calendar only in race week. Both sessions fall on days without a run, so the 4 running days stay intact. Most runners get the benefit of strength training from about 2 sessions a week held for 6 to 12 weeks or more, and in pooled trials extra sessions added nothing.
