Running Plan Review Buena Vida Run Club's 12-Week Sub-2:15 Half Marathon (5 days)
Plan at a Glance
Five running days is the lever this version pulls. A sub-2:15 half is rarely lost to a lack of speed. It is lost late, when the legs stop holding a pace they could run fresh. The fifth day adds easy miles that grow the engine without raising the strain of the hard sessions. You'll run goal pace until it stops feeling like a target. You'll learn to sit in a steady effort while the body tires under you. You'll finish a long run that carries goal-pace miles inside it. And you'll arrive at the start knowing what 10:14/mile feels like in your legs, not just on the watch. The week leans easy, with one interval session and one tempo holding the harder work. Three base weeks set the floor, a four-week build stacks goal-pace volume, then a short peak and two taper weeks. Mileage opens near 18 and tops out around 35. The plan gives goal pace as 10:14/mile and the race target as 2:14:03. This fits a runner already covering about 18 miles a week who has finished a half slower than 2:15. If a fifth weekly run would be brand new for you, spend two or three weeks adding it before day one.

Our Review
If you've finished a half somewhere north of 2:15 and want the next one to feel steadier instead of survived, this twelve-week plan fits you well. The verdict is simple: it is built for the part of this race that actually decides it, which is the back half. You won't be short on speed at 10:14/mile. You'll be short on the ability to hold it once you tire, and this plan spends most of its energy fixing exactly that. You'll meet goal pace early, in a week-3 interval session, then build it through reps that grow from 7 to 9 across the four-week build. In week 9 you'll run a continuous 4.1-mile block at goal pace. That same week you'll fold 3 goal-pace miles into the middle of a 12-mile long run on already-tired legs. That long run is the rehearsal that proves the finish is in range. The fifth weekly run adds easy aerobic miles that grow the engine without raising the strain of the hard days. This serves a runner already covering around 18 miles a week who can give five days to running and one to strength. Peak mileage tops near 35, so if you already train at 45 or more, you'll find this light. If a fifth weekly run is brand new, build into it before you start. For most runners chasing this time, the plan is a strong, honest fit.

Structure
Does the plan build you up smartly?
The arc is clean and easy to follow. Three base weeks lay the aerobic floor, a four-week build stacks goal-pace work, then a short peak and a two-week taper bring you to the line. Lighter weeks fall in week 4 and week 8 so the work settles before the next push. You always know which day carries the hard effort and which days are for recovery.
-
Prevention
Does the plan protect you from injury?
The plan ramps carefully and leans heavily on easy running, which keeps the strain in check. About 87 percent of your miles sit at easy effort, and two lighter weeks give the body room to absorb the work. The one watch point is week 9, where the load climbs sharply into the peak. Treat the easy days that week as truly easy and the jump stays manageable.
-
Flexibility
What happens when you miss a day?
The plan adapts well as you go, mostly through effort-based easy runs and goal pace given as a clear target you can hold by feel. The harder sessions read the legs for you: if a rep or a tempo costs more than it should, that is a signal to ease the next easy day. What it does not do is tell you how to catch up after missed weeks, so you'll handle disruptions on your own.
-
Readiness
Will the plan deliver race-day fitness?
You'll arrive ready to execute. Goal pace appears from week 3 and grows into a continuous block and a long run with goal-pace miles inside it, so race effort is familiar before the start. The two-week taper sheds volume while strides keep the legs sharp. The one gap is a tune-up race, which the plan leaves out, so the half itself is your first full rehearsal.
-
Variety
Are the workouts varied enough?
The sessions are varied and built with intent. Each workout type does a distinct job, from the goal-pace intervals to the weekly tempo to the strides, and none of them is filler. Easy runs change in length across the week so the load lands where it should. The mix stays honest to the goal: most workouts train your ability to hold a steady effort rather than chase top-end speed.

Twelve weeks begins here, and the honest thing about a beginning is how little it asks of you right now. You decided to chase something, and showing up this week is the move that makes the rest of it possible. These early days will feel quieter than a goal like this might lead you to expect, and that quiet is the design, not a mistake. Let the running settle into your week before it ever gets sharp. You are exactly where you should be at the start.
M 3.5mi Easy Run
Welcome to the first run of twelve weeks. The plan starts smaller than the goal might suggest, and that is on purpose. Run 3.5 miles at a pace where talking stays easy. Most runners go out faster than they need to on day one, so let this one feel almost too gentle. The work of week 1 is simply showing up for week 1.
Tu 3.5mi Easy Run
Run 3.5 miles, same easy effort as yesterday. Keep your breathing relaxed and your stride short. The legs may carry a little of yesterday's run, which is what stacking easy days is supposed to feel like. Slow down if your sentences start to break apart.
W 3.5mi Easy Run
Run 3.5 easy miles. Three days in a row of running is new stress for the body, so some stiffness in the first mile is normal. Let it loosen as you go. If it does not loosen by the halfway point, ease the pace until it does.
Th 3.5mi Easy Run
Run 3.5 miles at conversational effort. Forget the watch today and run by how the legs feel. Easy running this early lays the floor that the harder weeks will lean on. Finishing like nothing much happened is exactly the result you want.
F Strength Training
Sa 4mi Easy Run
Run 4 miles, the longest run of the week. Start a touch slower than your weekday pace and let the run come to you. By the last mile you should feel like another mile would be no trouble. It does not have to be, today.
Su Rest
This is the week running stops being an event and starts being a routine, and that shift matters more than any single day you log. Pulling on your shoes when the morning had other plans is the real engine behind a goal like this one. None of it looks like much from the outside. It also happens to be the part that actually works, so let it become ordinary.
M 3.5mi Easy Run
Run 3.5 easy miles to open the second week. The first mile after the weekend run often starts sluggish and frees up by the second. If it never frees up, cut the run short and call it done. Coming home more recovered than you left is the whole point.
Tu 3.5mi Easy Run
Run 3.5 miles, easy and unhurried. This week adds a small bit of volume without changing how anything feels. The trap is treating a short midweek run as a chance to test the legs. Keep it boring and save the legs for the weekend.
W 3.5mi Easy Run
Run 3.5 easy miles. The middle of the week is the recovery slot, and protecting it is what lets the weekend run land. Hold a pace where you could chat the whole way. If you cannot, you are running it too hard.
Th 3.5mi Easy Run
Run 3.5 miles at easy effort. These quiet runs are the connective tissue of the plan, the part nobody remembers afterward. They keep the aerobic engine growing between the harder days. Run relaxed and let the legs stay fresh. If it feels like nothing much happened, you ran it right.
F Strength Training
Sa 5mi Easy Run
Run 5 miles, the longest run yet on this plan. Most runners cross an hour here for the first time. Start easy enough that the early miles feel almost too slow. If the last mile asks you to back off, that is the right way for an early long run to end.

Plan Strengths
- You'll know what goal pace feels like long before race day, because it shows up from week 3 and keeps growing.
- You'll practice holding goal pace on tired legs in the week-9 long run, the exact thing the back half of the race demands.
- You'll spend most of the plan running easy, which builds the engine while keeping you fresh for the harder days.
- You'll get a built-in strength session each week, which protects the legs and joints across twelve weeks of building.
Weaknesses & Gaps
- You won't run a tune-up race, so the half itself is the first time you string goal pace across the full distance.
- You're on your own if you miss a week, since the plan gives no rule for catching up safely.
- You'll find this light if you already train above 45 miles a week, since peak volume tops near 35.
What's missing
A few gaps are worth naming. The plan never schedules a tune-up race, so the half is the first time you'll hold goal pace across the full distance. If you can, slot a 10K or a shorter race into a weekend in the build phase as a pacing rehearsal, replacing that week's tempo. There's also no rule for missed weeks. If you fall behind, repeat the most recent week you completed rather than jumping ahead to where the calendar says you should be. The strength sessions are on the calendar but left unspecified, so the content is up to you; two sessions a week of heavier lower-body work serves runners best. Finally, peak mileage near 35 will feel light if you already run more, in which case add easy miles to your weekday runs rather than touching the hard sessions.
What the science supports
Easy aerobic volume is the foundation
Most of this plan's miles are easy, and the fifth weekly run adds more of them. That is by design. Easy aerobic running is the foundation that supports the harder work, and studies consistently find it is what the higher-intensity sessions stand on. The week-3 intervals and the weekly tempo land better because the easy volume underneath them is doing its quiet job first.

Tapering improves race performance by 2-6%
The plan sheds volume across the final two weeks while keeping a little sharpness through strides. Research on tapering finds that a structured one-to-three-week reduction before a goal race improves performance by a few percent compared with training through. The flat legs you may feel in the first taper days are the body unloading, not fitness slipping, and the gain shows up on race day.
Rapid volume jumps raise injury risk
The single sharpest jump in this plan is week 9, where mileage climbs into the peak. Studies link rapid volume spikes, especially a week well above the recent average, to higher injury risk. The plan softens that with two lighter weeks beforehand and a heavy share of easy running. Still, week 9 is the one to respect: keep the easy days genuinely easy so the jump stays manageable.
About two strength sessions a week
One strength session sits on the calendar each week. The evidence suggests most runners get the performance benefit from about two sessions a week, kept on non-consecutive days over at least a couple of months. The plan's single weekly session is a floor, not a ceiling. A runner who can fit a second one, especially with heavier lower-body work, is likely to gain more.

Periodization beats constant-load training
The plan moves through clear blocks, and each carries a different emphasis. A base phase gives way to a build, then a short peak, then a taper. Studies find this kind of structured periodization produces better race results than holding the same training steady throughout. The base weeks build the floor and the build weeks stack goal pace, so each phase sets up the next.
