Plan at a Glance
If you're chasing a sub-1:30 half, you can probably already run goal pace. You may even have a race on your record where you did, for 10 miles, and then watched it come apart. That's the gap this plan is built around. It skips the 400s and the speed day you might expect. Instead it keeps coming back to goal pace: in short reps, then longer ones, then full miles, then long unbroken stretches, until the pace stops being an effort you spend and becomes a gear you own.
Each of the four runs in the week has one job. Tuesday is goal pace in pieces. Thursday is the big one, most weeks a threshold run at 10K effort, and a few times a race simulation or a progression run that puts goal pace on tired legs. Saturday is the long run, easy from the first step. Sunday is a medium-long on legs that still remember Saturday, and that weekend pair is how four days of running get some of what a six-day week gets from frequency. Four days is enough for this goal when each one knows its job. Strength sits on Monday and Wednesday, and Friday is yours.
It's written for a runner already averaging about 31 miles a week, with a half on their record not far off this goal. The plan opens at that load, not above it, and a lighter week arrives before you think you need it. The week after that lighter week is the steepest step of the build. Your legs will feel fresh, and your first long stretch at goal pace will feel easy for the first few miles. That's the moment to hold back. Don't open it faster than goal pace, and run the long run two days later at a pace you can talk at.
One more thing worth knowing. In the biggest week, the Thursday session, warm-up and cool-down included, runs longer than Saturday's long run. The hard days carry real weight here, so the easy ones have to be truly easy. Keep the weekend gentle and the work on Tuesday and Thursday has somewhere to land.
Below is the full Buena Vida review of the plan. We score every plan against our 30-point benchmark, which draws from peer-reviewed sports-science research and proven coaching best practices.

Our Review
A runner close to sub-1:30, with four days a week to give and a race where goal pace slipped away late, will find a strong match here. Its idea is simple and well carried out: make goal pace familiar, then make it durable. Tuesdays teach the pace in pieces, Thursdays add threshold work just above it, and a long race simulation and a progression run ask you to hold it on tired legs, which is where a half at this level tends to slip away. The structure around that work is sound, with clear phases, three cutback weeks, hard days that never touch, a warm-up before every hard session, and a patient taper. The gaps are few and specific. The biggest is the week after the first cutback, the sharpest jump in load in the plan, which also brings the first race simulation. Slightly more of the running sits at quality than is ideal. Run it, and give that one week some care.

Structure
Does the plan build you up smartly?
Block by block, with each phase easy to see: two weeks to settle into the load, eight weeks of sharpening, one taper week, then race week. The key sessions grow in readable steps. Intervals go from 6 x 0.5 mile to 7 x 0.75 mile to 6 x 1 mile. The threshold stretch inside the Thursday run grows from 5.1 to 5.5 to 5.9 miles, then to 7.2 and 8.5, before it shortens for the taper. Training in phases like this tends to beat holding one steady load, and each of the 19 hard sessions is spelled out in full.
-
Prevention
Does the plan protect you from injury?
Mostly, with week 5 the one to watch. Three cutback weeks (weeks 4, 8, and 10) break up the climb. Wednesday's strength session always sits between Tuesday's intervals and Thursday's long session, a free Friday keeps Thursday clear of Saturday's long run, and all 19 hard sessions start with easy running before the work. Week 5 climbs out of the 23.5-mile cutback week into the biggest jump in load in the plan, and it brings the first race simulation, 8.3 miles at goal pace, in the same week. Big jumps in running tend to raise injury risk, so this is the week to respect. The simplest fix is to cut that simulation to about 6 miles at goal pace, which keeps its purpose. Either way, keep Saturday's 11.5 miles easy and shorten Sunday if your legs are talking. Across the whole plan, easy running is a bit thinner than ideal, so the easy days have to stay easy for the hard ones to work.

Flexibility
What happens when you miss a day?
Most misses slide into an open day, since Monday, Wednesday and Friday hold no running before race week. Each session carries a priority, and the order tells you what gives way. Strength goes first, then Sunday's medium-long. Hold on to the three that carry the build: the goal-pace reps on Tuesday, the long Thursday session, and the easy Saturday long run. If Thursday slips, run it Friday and let Sunday's medium-long shorten or go. If Tuesday slips, run the intervals Wednesday, move Thursday's session to Friday, and again let Sunday give way, so the hard days stay a day apart. Lose a whole week and those Tuesday and Thursday sessions stay missed: rejoin at the current week instead of piling them on top. And if an injury keeps you off your feet, Thursday is the first session to rebuild when you come back.

Readiness
Will the plan deliver race-day fitness?
Goal pace runs through the whole build: goal-pace intervals on most Tuesdays, a race simulation with 8.3 miles at goal pace soon after the first cutback, a progression run that closes with 4.6 miles at goal pace, and a shorter simulation on rested legs in the taper to confirm the pace. A 52-mile peak week and a 15-mile long run fit the distance. Volume comes down across the last three weeks while the 6 x 1 mile session stays in, so goal pace stays in your week even as the miles fall away. The 15-mile long run lands three weeks before race week, and the long runs after it step down to 12 and then 10 miles.

Variety
Are the workouts varied enough?
Every change in this plan has a job. You'll run eight kinds of sessions: easy runs, long runs, medium-long runs, threshold runs, goal-pace intervals, a progression run, race simulations and the race itself. The intervals lengthen as the build goes, and Thursday rotates between threshold, race simulation and progression, so the same pace keeps arriving in a new shape. Nearly all the hard work sits between threshold effort and goal pace, because a half at this level is decided by how long goal pace lasts, not by top speed.

Your half marathon goal time is one you set yourself, and this is the week you actually start chasing it. The weeks tend to keep a similar shape, so the rhythm grows familiar even as the targets sharpen. The arc over these 12 weeks is not mysterious. You stack the load and absorb it. Then you sharpen, and then you race. What matters now is meeting the first block on its terms, rather than on the terms of whatever fitness you happen to walk in with. Settle in.
M Strength Training
Tu Intervals: 6×0.5mi @ ½ Marathon
2-mile warmup, 6 x 0.5 mile at goal pace with 400 m recovery jogs, 2-mile cooldown. The first interval session of the plan. Goal pace will feel faster here than it should. That's normal while the legs haven't yet trained for 6:49/mile. Run the early reps controlled. The work is teaching the body what 6:49/mile is, not proving you can do it. By the third rep you'll find rhythm. Watch for drifting under 6:49/mile as you warm up. That is the trap.
W Strength Training
Th 9.1mi Threshold Run with 5.1mi @ Threshold
2-mile warmup, 5.1 miles at 10K effort, 2-mile cooldown. The first threshold of the plan. 10K effort is sustainable, not hard. If your breathing turns ragged in the first mile, you're running closer to 5K effort. The pace will feel patient compared to Tuesday's intervals. That is the point. Threshold is a different kind of work from 6:49/mile, and it only does its job if you respect the effort cap here. The session was a success if the final stretch held pace without the form unraveling.
F Rest
Sa 8mi Long Run
8 miles at fully easy effort. The first long run of the plan is the floor everything else builds from. The pace should feel slower than you want. That is how you know it is right. A long run that leaves you depleted on Saturday costs Sunday's medium-long, which costs Tuesday's intervals. The chain matters here. Finish with the sense that another 2 miles would have been possible.
Su 5.5mi Medium-Long Run
5.5 miles at aerobic effort on legs that still remember yesterday. The medium-long on tired legs is what gives a 4-day plan the back-to-back stress that 5- and 6-day plans get from frequency. Run it conversational. Pace doesn't matter here. Finishing aerobic does.
The second pass at this kind of load is where the engine starts to pay attention. Most of what changes now happens out of sight, in the legs and the heart. None of it shows up on a watch this early, but all of it is working. The easy days are doing more than they look like they are doing. If anything wants to creep faster, keep a hand on it. Build the floor before you add anything on top.
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 9.5mi Threshold Run with 5.5mi @ Threshold
2-mile warmup, 5.5 miles at 10K effort, 2-mile cooldown. Threshold extends 0.4 miles past the 5.1-mile opener. The change is small enough that the effort should feel the same. If it feels harder, you're running threshold a touch too fast. Patience here pays off later, when the same effort holds for 8.5 miles. Sustained efforts like this are practice at holding a hard pace while breathing stays under control. Comfortably hard means a few words at a time, never full sentences.
F Rest
Sa 9mi Long Run
9 miles, easy from the first step. Long-run progress at this tier comes from accumulated minutes and from controlling effort across them. If you find yourself drifting toward marathon effort by mile 7, the run has stopped being aerobic.
Su 6mi Medium-Long Run
6 miles easy on back-to-back legs. Effort should feel familiar by now. The medium-long on tired legs is the rhythm this plan returns to ten more times. Conversation pace, no exceptions. If easy still feels like work, give yourself 10 extra minutes to warm up before the first mile begins.

Plan Strengths
- Goal pace is installed in steps, from 6 x 0.5 mile to 7 x 0.75 mile to 6 x 1 mile, then in continuous stretches up to 8.3 miles, so the pace becomes familiar before it has to hold up under fatigue.
- The threshold stretch inside the Thursday run grows from 5.1 to 8.5 miles at the same 10K effort, so you learn to hold a hard, steady effort for longer.
- Three cutback weeks (weeks 4, 8 and 10) and hard days that never fall back to back give your legs regular breaks from the climb.
- Volume comes down across the last three weeks while the 6 x 1 mile goal-pace session stays all the way to race week, so you keep touching goal pace every week even as the miles fall.
- All 19 hard sessions, from the first 6 x 0.5 mile to the last threshold run in race week, carry a warm-up and a note on what the session is for and how it should feel.
Weaknesses & Gaps
- The week after the first cutback (week 5) is the steepest step in the plan. Volume climbs from about 23 miles to about 40, and the first race simulation arrives in the same week.
- The share of easy running is a little lower than ideal, since the Thursday sessions are long and the goal-pace work adds up.
- Out of each cutback the long run jumps 4 or 5 miles at once, which can make those rebound runs feel long.
What's missing
Two optional additions suit this runner. Strides appear once, on the Friday shake-out before the race. They're cheap practice at running fast, so adding 4 to 6 relaxed strides of about 20 seconds after one easy run a week, from early in the build, is worth the few minutes. Sunday's medium-long or a cutback-week Tuesday are good homes for them. And if your race course rolls, move a few Saturday long runs and Sunday medium-longs onto rolling routes and keep the effort easy on the climbs. On a flat course, the plan as written covers it.
What the science supports
Shifting training emphasis beats unchanging training
The 12 weeks divide into four phases. Base Building, weeks 1 and 2, sets the rhythm. Sharpen runs from week 3 through week 10, with cutback weeks at 4, 8 and 10 breaking up the climb. A 1-week taper follows, stepping volume down while the goal-pace miles stay, and race week closes the cycle. Planned shifts in emphasis like these tend to beat holding one load the whole way through, though the margin in trials was small.

Easy miles do most of the work
Close to three quarters of your running sits at easy, conversational effort, and easy miles like these form the base that harder training stands on. The hard work lands twice a week in building weeks: Tuesday's goal-pace intervals and a Thursday session at threshold or goal pace. The Saturday long run and Sunday medium-long hold easy pace, on tired legs, building endurance without adding intensity.
Polarized training matches or beats threshold-heavy plans
Polarized training pairs plenty of easy running with a few clearly hard sessions and leaves little in the medium-hard middle. For trained runners it matches or beats a plan built mostly on threshold work, and mixes with a little more steady running do about as well. This plan sits in that sound range. It keeps its hard running to Tuesday and Thursday, follows each with a strength day or a day off, and holds every Saturday long run and Sunday medium-long at easy effort.

A real taper sharpens you for race day
Week 11 trims volume about 30 percent below the week 9 peak, and the running in race week, before the race itself, comes to less than 40 percent of that peak. The full 6 x 1 mile at goal pace stays in both weeks, beside a short race simulation and then a short threshold run. A taper of this kind, cutting the running by roughly 40 to 60 percent while some fast work stays in, improves race performance compared with training straight through.
Threshold or race pace: neither proven better
Whether race-pace work or threshold work matters more is an open question. For recreational runners, both are reasonable kinds of training, and no study shows one beating the other. This plan works both sides of the question. Tuesday goal-pace reps grow from 0.5 mile to a full mile, while Thursday threshold runs at 10K effort climb from 5.1 to 8.5 miles by week 9.
