Running Plan Review Buena Vida Run Club's 12-Week Run Your First Half Marathon (4 days)
Plan at a Glance
Most first-half-marathon plans cannot afford to wait. Ten weeks is the common shape, and harder running has to start in week 3 or 4. Twelve weeks buys something different. The first four weeks here are pure easy running. No tempo runs, no hill repeats, no fast strides until the second month. By the time faster work shows up in week 6, you have a full month of conversational miles behind you. That changes what a tempo (a comfortably hard pace where full sentences disappear) feels like when you meet it.
13.11 miles is far enough that the body has to learn the distance. It is short enough that most first-timers try to rush the build. The common mistake is running the easy days a little fast. You feel strong in week 3 and start pushing. By week 7 the legs are tired before harder work even arrives. Easy days have to stay easy. On this plan, easy means slow enough to hold a full conversation. If you cannot, you are running too hard.
Buena Vida built this for a runner who can already cover about 8 miles a week. You run four days a week. The long run climbs from 4 miles to a peak of 11 miles, sitting two weekends before race day. Tuesday holds one strength session every week. Week 9 threads three miles at half marathon effort through the middle of the long run, so race pace is not new to you on race day.
What follows is Buena Vida's full review of the plan. Every plan is scored against our detailed, 31-point benchmark, drawn from peer-reviewed sports-science research and proven coaching best practices.

Our Review
You are twelve weeks out from your first half marathon, with about 8 miles a week already in your legs. You sit in a spot the catalog often misses. You either get a plan that compresses base into ten weeks because the calendar is shorter, or one that assumes mileage you do not yet have. This plan does neither.
You spend four weeks on pure easy running with no harder work anywhere on the calendar. By the time you taste faster running in week 6, your aerobic system has done a full month of base work. You feel the hill day land on legs that have grown ready for it. You watch the tempo block grow from a half mile in week 7 to one mile by week 10. Your week 9 long run threads three miles at half marathon pace (HMP, the effort you want on race day) through the middle, so you arrive having already practiced it over distance.
You get a strength session every Tuesday, set clear of both the Friday faster day and the Saturday long run. The lifts themselves are left to you, which suits a first-timer who can start simple. The catch is the climb out of the week 4 cutback: mileage jumps about 75 percent into week 5, and the next stretch runs hard for six weeks with no programmed deload. Watch that step, and back off if a niggle appears.
This plan fits a first-timer who came to finish strong rather than chase a time. If a sharp clock matters more, look for a 4-day plan with more tempo volume than the single peak mile here.

Structure
Does the plan build you up smartly?
Mostly, and the shape is easy to follow. The plan moves through four named phases. Four weeks of easy base, six weeks of build, one week of taper (cutting the running back so you arrive fresh), then race week. The long run grows from 4 miles to a peak of 11, and hard days never land next to each other. The one gap: after the week 4 cutback, the six build weeks run straight through with no second lighter week. That stretch leans on you to keep the easy days honestly easy so the load does not pile up.
-
Prevention
Does the plan protect you from injury?
Yes for the most part, with one rough step to know about. Easy runs stay easy, the build climbs gently for a first-timer, and each hard day has an easy day on either side. The week 11 taper lets the body soak up the work before race day. The gap is the jump out of the week 4 cutback. Mileage rises about 75 percent into week 5, then six build weeks run without a lighter one. Those weeks ask the most of your legs, so the early easy miles are where you bank the room to handle it.
-
Flexibility
What happens when you miss a day?
Miss an easy day and the plan barely feels it. Every week follows the same easy, strength, easy, faster, long shape, so the rhythm is yours to lean on. Each run carries a priority, which tells you what to guard when a week gets tight. The long run on Saturday is the one to protect. What the plan does not spell out is how to make up a long run you had to skip. That choice stays with you.
-
Readiness
Will the plan deliver race-day fitness?
Yes, with one piece of race practice left thin. The long run climbs from 4 miles to a peak of 11, sitting two weekends before the start, and the week 9 long threads 3 miles at half marathon pace (the speed you plan to run on race day) through the middle. Peak weekly mileage of about 18.5 miles fits a first-timer aiming to finish strong, and the taper drops cleanly into a 15-minute shake-out two days out. The thin spot: that 3-mile block is your only run at race pace. It teaches the feel once rather than building it across several weekends, so race day is the second time you hold it for real.
-
Variety
Are the workouts varied enough?
Yes, the mix is right for a first half. Easy runs and the Saturday long run carry most of the work, with hills, a fartlek (a run where you mix in faster bursts), a growing tempo block, and weekly strides layered on top. The tempo block climbs from a half mile in week 7 to a full mile by week 10. What keeps this from a top mark is dose, not range. There is one hard session a week at beginner-sized amounts, which is the right call for a first-timer but leaves the variety lighter than a deeper plan would carry.

Here you are at the start of something you decided to do, and that decision is worth honoring as you lace up for the first run of the plan. The early weeks are not meant to feel impressive, and that is on purpose, because a body that has not been running this often needs time to remember the rhythm of regular movement. Show up when the calendar says to, and let the easy runs stay honestly easy. Twelve weeks looks long from where you are standing right now, and that is fine, because you only have to be present for the week you are inside of.
M 1.5mi Easy Run
First run of the plan, 1.5 miles at a conversational pace. The point of week 1 is not the distance. It is teaching your breathing and your legs what easy actually feels like, before any mileage starts to grow. Most first-time half-marathoners try to make week 1 feel like progress and end up running it too hard. If your breathing tightens past the point where you could speak a full sentence, slow down. The next eleven weeks need this gear available.
Tu Strength Training
W 1.5mi Easy Run
Wednesday easy. 1.5 miles at the same conversational effort as Monday. Should feel almost dull, which is the point this week. Boring early means harder running lands clean later. Miles like these are where the base quietly accumulates, one unremarkable run at a time.
Th Rest
F 1.5mi Easy Run
Friday short run before tomorrow's first long run. The long run is just the longest run of your week, the one that builds your distance over time. On this plan it lands on Saturday. Today is 1.5 miles, loose and slow. Save anything sharp for the morning.
Sa 4mi Easy Run
Your first long run of the plan, 4 miles at conversational effort. The legs may surprise you in either direction. Fresh and ready, or heavier than expected. Both are normal at week 1. Run by breath. Pace will follow. If you can hold a full sentence between strides, you are doing it right. The long run is where most of the work pays off. Show up to it weekly, conversational, every weekend.
Su Rest
The second week is about doing it again, which sounds small but is actually most of what training is. Your job right now is to make running a regular shape in your week rather than a special event you have to summon energy for. Some mornings will feel willing and some will feel reluctant, and both kinds of mornings count exactly the same toward the runner you are quietly becoming.
M 1.5mi Easy Run
Monday easy. 1.5 miles, same conversational gear as last week. Legs may feel slightly heavy from Saturday's first long. That is the long run paying for itself. Jog it out at true effort and let the body settle in.
Tu Strength Training
W 1.5mi Easy Run
Wednesday easy. 1.5 miles, steady minutes. Effort goal is the same as Monday. Nothing more is asked. The job today is gentle repetition, the kind of running that adds up without ever feeling like work.
Th Rest
F 1.5mi Easy Run
Friday primer. 1.5 miles before tomorrow's 5-mile long run. Stay loose, stay slow. Save the legs for the weekend. Easy days exist to let the harder days land, and they only work if they stay easy.
Sa 5mi Easy Run
Long run. 5 miles easy, conversational throughout. About a mile longer than last weekend's 4. The new ground at the end may take a few minutes to settle. Walk for thirty seconds if breathing rises, then start running again. The long run grows by roughly a mile a week through the base phase.

Plan Strengths
- You run four full weeks of easy-only base before any hard session, so faster work lands on an aerobic system that is ready for it.
- Your long run grows from 4 to 11 miles, then steps back twice so your legs reach race morning fresh.
- Faster running enters in week 6 with hills and a fartlek before any tempo, easing you into harder efforts.
- Six-plus session types keep the work varied: a tempo ladder, hill repeats, fartlek, strides, and an embedded race-pace block.
- The plan teaches as it goes, explaining why easy means easy and how to read tempo effort, so you can coach yourself.
- Your week 9 long run holds three miles at half marathon pace, so race effort is familiar before race day.
Weaknesses & Gaps
- Mileage jumps about 75 percent out of the week 4 cutback, the sharpest step in the plan and the one most likely to bite.
- Six Build weeks run back to back with no deload between them, so fatigue can stack before the taper unloads it.
- Peak tempo tops out at one mile, the right dose to finish your first half but light if you want a fast clock.
- Race morning is the first time you cover the full 13.1 miles in one go, with the longest run reaching 11.
What's missing
The plan handles the big risks of a first half well, so the gaps are narrow. The main one is recovery rhythm: a single cutback in week 4, then six straight Build weeks with no programmed deload. The climb out of that cutback is steep, about 75 percent into week 5, which is where a beginner is most likely to feel a niggle. If a week feels heavy, repeat the prior week rather than push the next jump, and treat any sharp pain as a reason to ease back. The other gap is specific to a time goal. The peak tempo block sits at one mile, plenty to carry you across the line but light if you want a fast finish. If the clock matters, swap one easy day for a longer tempo, or pick a plan built with more threshold volume. To finish strong, the plan as written needs nothing added.
What the science supports
Periodization beats constant-load training
The plan breaks into four phases. Foundation runs for four weeks at easy effort only, building the base before any harder work arrives. Build takes six weeks where faster sessions start in week 6 and tempo grows across four weeks. Taper drops the load in weeks 11 and 12 before race week. Research shows this kind of structured progression produces better results than running the same way every week.

Easy aerobic volume is the foundation
Most of your running stays at conversational pace where you can hold a full sentence the whole way. About 80 percent of your weekly miles live at this easy effort. Harder sessions arrive only in weeks 6 through 10. Research shows that the bulk of a runner's training should sit at low intensity, building the aerobic foundation that allows harder work to land clean. The long run grows on easy effort alone from 4 miles to 11, proving the point week after week.
Haugen et al. 2022; Casado et al. 2022; Tønnessen et al. 2014
Keep easy days easy, hard days hard
Your schedule follows the same pattern every week. Two easy runs, one harder session, and one long run. The hard session is hills, fartlek, or tempo. This clean separation between easy and hard days is what research shows first-time half-marathoners need. Easy days let the body recover and stay fresh for the harder work, which stays short and specific. Conversational pace drives most of the work. The rare faster sessions teach the body without reshaping the recovery week.
Stöggl & Sperlich 2014; Casado et al. 2022; Kenneally et al. 2017
Tapering improves race performance by 2-6%
Weeks 11 and 12 step the volume back by about 40 to 60 percent, intentionally easing the load before race day. The taper maintains a touch of faster running (strides and a short fartlek) to keep the legs sharp. Volume drops to let your body absorb the past ten weeks. Research shows this taper structure produces 2 to 6 percent performance improvements on race day. You arrive fresh rather than ground down.
Long runs are essential for marathon
Your longest run peaks at 11 miles two weeks before the race, near the goal race distance. Week 9's long run threads three miles at half marathon goal pace through the middle so race effort feels familiar on race day. Research shows that long runs at moderate duration (one and a half to three hours) build the specific capacity to hold pace over distance. Without them, you have no race-specific work to fall back on. The long run is where most of your readiness gets made.
