Plan at a Glance
Three runs a week isn't much room, and the natural instinct is to make every one of them hurt. This plan does the opposite. Monday is easy. Saturday is long and mostly easy. Thursday is the one day that asks for real effort, and almost every time that effort is the pace you want to hold on race day. Strength fills Tuesday and Friday, and the rest is rest.
That one hard day carries a lot. The first goal-pace Thursdays are short, steady blocks wrapped in an easy warm-up and cool-down, and they grow a little every few weeks until goal pace stops feeling like a guess. In the biggest week, Saturday's long run reaches 13 miles with 3 of them at goal pace in the middle, after you've already been running for most of an hour. That's the closest you'll come to the race before the race, and it shows you what the middle miles of a sub-2 half feel like on legs that have already done some work.
Then there are the easy days. By the biggest week, Monday's easy run is longer than any Thursday session in the plan. You'll start it fresh after a Sunday off, and somewhere in the first mile the pull will be to settle into a comfortable, moderate pace that feels productive. Hold the pace you can talk at instead. A Monday run too fast leaves Thursday flat. A Monday run easy leaves Thursday sharp. Lighter weeks come around every few weeks to let the work settle, and the last stretch trims the miles while a short goal-pace block stays in every week, so race week is light with the rhythm already rehearsed.
It's built for a runner who already handles about 16 miles a week over three days, whose other mornings belong to work, kids or another sport, and who wants a sub-2 half without giving one of them up.
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
If you've wondered whether three days a week is serious enough for a sub-2 half, this plan is a good answer, and you can start it with confidence. It's a well-ordered plan that knows what it's for: one hard day, two easy runs around it, and a lot of patience. Monday and Saturday carry the easy miles, Thursday is the week's one hard day, and its goal-pace work builds from a 3.2-mile block to 4 miles, then shrinks through the taper without ever disappearing. The long run climbs from 5 miles to 13 and peaks three weeks before the race. That shape is what lets the one hard day be truly hard, because the two easy runs around it leave you room to recover.
The gaps are real, and both are worth planning around. Nearly every hard session is the same kind of work at the same pace, so Thursdays give you little practice at anything faster than goal pace. The week after the first cutback also asks for a lot at once, with a longer Monday, the longest tempo yet, and your first 9-mile long run. Neither should stop you. Run that week at the easy end of every effort, and let Saturday's 9 miles be slow.

Structure
Does the plan build you up smartly?
Nearly. The phases are named and explained on the calendar, but the hard work never changes kind. Goal pace carries almost every Thursday from the first tempo to the taper, with no earlier block built around a different sort of hard running. What the plan does in full is spell out each session. Every Thursday is written out piece by piece, from the warm-up miles to the cool-down, with a note on what that day is building.
-
Prevention
Does the plan protect you from injury?
By keeping the hard work to one day. Easy running makes up most of your miles, which lets Thursday be genuinely hard instead of everything being a little hard. Each Thursday session opens with 1 to 1.5 easy miles and closes with 1 to 1.5 more, two days separate it from Monday and one from Saturday, and the lighter weeks land in week 4 and week 8. The soft spot is the week after the first cutback: Monday's run, Thursday's tempo and Saturday's long run all step up at once, and Saturday becomes your first 9-miler. Your breathing may feel ready for that 9-miler before your tendons are, and a jump like this one is where injury risk tends to climb. Run that Monday slower than you think you need to, and if the last miles on Saturday go heavy, it's fine to stop early. Week 2 is a smaller version of the same thing: your first goal-pace tempo arrives as the mileage rises, so ease into that block rather than attacking it.

Flexibility
What happens when you miss a day?
Every run here has a day off from running on both sides, which gives a missed one room to move. With only three runs, any miss can feel big, but a missed Monday can slide a day or two later without crowding Thursday. When something has to give, keep Saturday's long run and Thursday's goal-pace session first, Monday's easy run next, and strength after that. If you miss a Thursday, don't make it up on Saturday. Run the long run as written and pick goal pace back up the following week. The plan doesn't say what to do after an illness, but if one takes most of a week, repeating that week is safer than stepping straight into a bigger one.

Readiness
Will the plan deliver race-day fitness?
This is where the plan is most focused. The peak week and its 13-mile long run sit right where a half marathon needs you, and they land three weeks out so the taper has time to work. Goal pace shows up in most weeks, and in the peak week's long run you'll hold 3 miles of it after 5 easy ones, the closest you'll get to the middle of the race before race day. The longest unbroken goal-pace block in the plan is 4 miles, and the race asks for 13.1. The plan trusts the easy miles and that one long-run rehearsal to carry you the rest of the way. Then the taper cuts the miles while keeping a short goal-pace block every week. The step down from 28.5 miles at the peak to 23 and then 19 is the kind of cut that tends to help runners race better than training straight through.
-
Variety
Are the workouts varied enough?
Yes across the week, with one gap in the hard days, which lean almost entirely on goal pace. The range of runs is good: easy runs, long runs, Monday strides, goal-pace runs, a fartlek, a shake-out and the race. Eight of the nine hard sessions are goal-pace runs, and the ninth is a single ladder fartlek. That makes the hard work very specific to your race, with goal pace practiced in most weeks. What it gives up is variety in the hard work itself: no intervals, no hills, and little time faster than goal pace. A second format or two would give your Thursdays another gear to draw on. The Monday strides cover some of that, as low-cost practice at fast running, so run them every time they appear.
Workouts

You picked a goal that asks for 12 weeks of patience, and standing at the front of that is its own thing. The early runs will feel lighter than what is coming, and that is on purpose. The work right now is building the habit of showing up. Keep the easy days actually easy, even when the legs want to do more. The fitness you race with starts arriving later. For now, settle in.
M 5.5mi Easy Run
5.5 miles at conversational pace. The first run of the plan is your first measurement of where 'easy' actually lives in your legs. Most runners start a plan a step too fast on day one because the schedule still feels new and exciting. Today's job is to find the pace where you can speak in full sentences without breath catching, and to hold it for all 5.5 miles. If you finish wanting another mile, you got it right.

Th 5.5mi Easy Run
Second easy run of the week. Same effort as Monday: full-sentence pace. Don't recalibrate up because the legs feel willing today. The point of three easy runs in a base week is volume at low cost. Faster pace turns each into a small expense Saturday's run can't afford.
F Strength Training
Sa 5mi Easy Run
5 miles easy. Easy from start to finish, even if mile 3 feels like the legs want to wake up. This run isn't where you prove anything. It's where you teach the aerobic system to keep going past the middle without form falling apart. Watch the last half-mile, where pace creep usually starts.
Su Rest
Things begin to take shape now, with a little more asked of each day. You are still in the early stretch of the build, the part where nothing dramatic is happening yet and that is exactly right. Most of what makes a fast half possible is laid down in weeks that look ordinary from the outside. Keep the easy runs truly easy and let the harder day be the only hard thing in the week.
M 6mi Easy Run
6 easy miles. Same conversational effort. By week's end, the legs will feel the cumulative load if the easy days have stayed actually easy. If they're already worked, the pace was off. Watch Thursday's tempo for the same signal.

Th 6.2mi Pace Run with 3.2mi @ ½ Marathon
1.5 mile warmup, 3.2 miles at goal pace (9:06/mile), 1.5 mile cooldown. Your first contact with race effort under load. The warmup is doing more than warming, it's calibrating, so settle into rhythm before mile 1.5 closes. The first mile of tempo should feel sustainable. The second should ask for focus. The third is the check test: if it's drifting fast, you started too quickly. Watch the last half-mile of the tempo rather than the first. That's where every tempo from here tells you how race day will go.
F Strength Training
Sa 6mi Easy Run
6 miles aerobic. Same conversational pace as Monday. Saturdays sit on top of Thursday's tempo, and the legs may carry a little of yesterday's effort into the first mile. That's normal 2 days after a tempo. Let it shake out by mile 2 rather than chasing it. The job is volume at low cost. This isn't a redemption run for a hard Thursday.

Plan Strengths
- One hard day a week, kept apart from the others, so Thursday can be run with real intent and the easy days can stay easy.
- Goal-pace work builds from a 3.2-mile block to 4 miles, then gets rehearsed on tired legs inside the peak week's 13-mile long run.
- A taper that cuts the miles but keeps a goal-pace block every week, right up to race week.
- Each Thursday session is spelled out segment by segment (warm-up miles, the goal-pace block, cool-down) and explains what that day's work is building.
- Strength twice a week on non-running days, plus strides on most Mondays.
Weaknesses & Gaps
- Eight of the nine hard sessions are goal-pace runs, with one fartlek and no intervals or hills, so the hard days offer little range.
- The week after the first cutback stacks a longer Monday, the longest tempo yet and the first 9-mile long run.
- The first goal-pace tempo arrives in week 2, the same week the mileage climbs.
What's missing
If you want a second gear on Thursdays, swap the week 3 pace run for short repeats at threshold effort (a few minutes hard, a couple of minutes easy, about the same total time). It comes early enough that you give up none of the goal-pace practice the later weeks depend on, and it adds the range the hard days otherwise lack. If you want more aerobic work without more pounding, an easy bike ride on Wednesday fits in without crowding the 3 runs.
What the science supports
Keep easy days easy, hard days hard
From week 2, Thursday carries the hard session in most weeks, while the Monday and Saturday runs stay mostly easy and conversational. That lets Thursday be run with real intent instead of every run drifting toward a medium effort. Trained runners may improve more by keeping easy days truly easy and hard days clearly hard. It is the pattern top runners use, a sensible default rather than a proven edge.

Easy miles do most of the work
Outside the Thursday sessions, nearly every Monday and Saturday run sits at easy conversational pace, and about 85% of the plan's running happens at low intensity. That easy-paced volume is not filler. It's the base that Thursday's goal-pace sessions and the Saturday long run rest on. Elite distance runners do most of their running this way, about 80 percent or more of it. The harder work is only possible because the base is deep enough.
Threshold or race pace: neither proven better
For recreational runners, goal-pace work and threshold work are different kinds of training, and either is a reasonable way to prepare. No study shows one beats the other. Goal pace for a sub-2 half sits a little easier than threshold, the effort where comfortable running tips into real work. Week 6's ladder fartlek, a run of surges with easy jogging between, adds 2 surges of 60 seconds at threshold effort. That gives you a taste of both kinds of work.

A real taper sharpens you for race day
Week 10 is where the taper opens. Mileage drops about a fifth from the peak week, with all 3 runs shorter, but Thursday's pace work stays so the legs don't lose the rhythm they have learned. Week 11 lightens further. By race morning you have 12 weeks of training behind you, and the taper lets its fatigue clear instead of chasing fitness. In pooled trials, a taper like this one (lower volume with some speed kept) gave a moderate boost in race performance over not tapering.
Two strength sessions a week is enough
Tuesday and Friday strength sessions sit on the days between runs in every week through week 11. About 2 strength sessions a week, kept up for at least 6 to 12 weeks, is where most runners get the benefit. In pooled trials, adding more sessions a week did not add more. For a 3-day plan, those 2 weekly slots are a core part of the week, not an extra.
