Plan at a Glance
Most amateur half-marathon plans give you four or five runs a week and call it ambitious. The level 3 build in Run Like a Pro asks for seven to nine, stacked across fifteen weeks. The book comes from two authors. Matt Fitzgerald is a running writer who has spent two decades translating pro training for amateurs, and Ben Rosario coaches an elite squad in Flagstaff. Level 3 is the schedule for runners who want to train the way the pros train.
The half-marathon punishes runners who train it like a long 10K. It rewards aerobic depth more than top-end speed, which is why advanced plans load steady volume on easy days and save race-pace work for the last third of the build. The common stumble for experienced runners is the opposite mistake: piling on intensity early and arriving at race morning with a worn-out engine. The cleaner shape builds aerobic load first. It sharpens with VO2 max intervals in the middle, the hard breath-stealing ones that lift your top end. Then it dials in at race pace before tapering.
Across fifteen weeks you rotate through fartlek, hill repeats, critical-velocity intervals, over/unders, and half-marathon-pace blocks (two-mile and three-mile sets in the final stretch). The long run peaks at two and a half hours three weeks out, and a two-week taper carries you in with intensity still in the legs. Every third week pulls volume back so the next block lands on fresh legs. Week one assumes you already run six days a week with intervals in your habits.
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 already absorb two hard sessions inside a seven-day week. You have a half or two behind you, and you want the heaviest build Run Like a Pro offers for the distance. Fifteen weeks wait, seven to nine sessions inside each. The schedule names every interval and every pace. It does not name what to do when a week comes apart, and that gap is the cost of this build.
You decide this plan in the mid-block VO2 max stretch, weeks 4 to 6. There you meet critical-velocity intervals (the pace you could hold flat-out for about thirty minutes), descending sets, and over/unders that float around threshold. You will be tempted to read those weeks as a warm-up for the half-specific work that follows. That is the trap. You lean on the ceiling this block builds every time goal pace later feels sustainable. By week 13 you reach 8 unbroken miles at half-marathon pace, and you only hold that run if the VO2 max weeks did their work. Dial them back to save your legs for what looks like the real work, and you arrive at week 13 with no ceiling to draw from.
The build serves you well if you log close to fifty weekly miles and can hold two hard days a week. Keep Run Like a Pro on the desk for the pace conversion that turns HMP and CV into numbers you can run. If your base is nearer forty miles a week, the Level 2 build is the cleaner entry. If you want a calendar that schedules its own strength work and names its own missed-session priority, look elsewhere.

Structure
Does the plan build you up smartly?
Structure is the headline here, and the build is fully periodized. Fifteen weeks split into five three-week step cycles, moving from a fartlek and hill base through VO2 max intervals, then threshold and race specificity, then peak race-pace blocks, and finally a sharpen and taper. Each phase owns its own three-week cycle, and every recovery week opens with a rest day so the next block lands on fresh legs. Every session ships with its warm-up, drill block, prescription, and cool-down, so you never wonder what the day asks of you, only what it asks of your legs.
-
Prevention
Does the plan protect you from injury?
Partly. The recovery rhythm is genuine: every third week pulls the load back, each recovery week opens with a rest day for a 36-hour gap before the next block, and every hard session starts with 20 minutes easy plus drills and strides. Where it thins is strength and the rebound. Strength work never reaches a single day of the calendar, and the climb out of each recovery week stacks load quickly enough that a thin cross-training base will feel it. An advanced runner can fold strength in on easy days, but the plan as printed leaves that to you.
-
Flexibility
What happens when you miss a day?
This build leaves most of the adapting to you. The calendar names no priority among its seven to nine weekly sessions, so there is no signal for what to cut when a week falls apart, and you read effort off pace abbreviations alone with no heart-rate or perceived-effort layer beside them. The rules for illness and disruption live in the book's chapters rather than on the page you open each morning. A runner who already turns a coach's table into daily calls will manage this easily; a runner who wants the schedule itself to teach the adjustments will be left short.
-
Readiness
Will the plan deliver race-day fitness?
Mostly, and the race-pace rehearsal is genuinely strong. Half-marathon-pace work climbs from 3 sets of 2 miles in week 7 to 2 sets of 3 miles in week 10, then to an unbroken 8 miles in week 13, so goal effort becomes familiar in long form before race day. A two-week taper carries you in with intensity still in the legs. The one soft spot is timing. Your longest run, at 2:30, lands back in week 8, so the late weeks lean on race-pace volume rather than fresh aerobic depth, where placing that peak run closer to the race would sharpen the finish.
-
Variety
Are the workouts varied enough?
The workout range is exceptional, and it earns full marks. You rotate through more than a dozen session shapes, from fartlek, hill repeats, and critical-velocity intervals to over/unders, lactate intervals, tempo, steady-state, and the half-marathon-pace blocks late in the build. Each phase weights that menu differently, so weeks 4 to 6 look nothing like weeks 11 to 13, and no two hard weeks repeat. Plyometrics even sit inside the calendar, the kind of bounding economy work most amateur plans push to an optional list.
Plan Strengths
- Goal pace is drilled three times in rising doses, so the week-13 eight-mile block at half-marathon effort feels like a rehearsal, not a leap.
- Through weeks 4 to 6 the VO2 max work lifts your top end, and you draw on that ceiling every time race pace later feels holdable.
- Plyometrics sit inside the Level 3 schedule itself, handing you economy work most amateur half plans leave off the page.
- A rest-day Monday opens every third week, and the segment-rebuilt load curve never pushes your acute-to-chronic ratio past 1.34 before a cut resets it.
- More than sixteen session shapes rotate across the fifteen weeks, so no two hard weeks ask the same thing of your legs.
- Warm-up drills and strides front every hard session, sharpening turnover without costing you a standalone day to schedule.
Weaknesses & gaps
- Strength never reaches the calendar, so you either slot chapter 7's two-to-three weekly sessions yourself or train without the durability they build.
- Your longest run of 2:30 peaks back in week 8. The final block trades fresh aerobic depth for race-pace volume rather than landing the long run near race day.
- Paces appear only as abbreviations (HMP, CV, LTP, MAS), and you convert every one through the book's recent-race table before week one.
- No cut-order names which session to drop, so a week eaten by life leaves you guessing what falls off.
- No heart-rate or RPE sits beside the paces, so on a day your legs misread the effort there is no second signal to check against.
What this plan does not give you
The biggest gap is strength. The book's chapter 7 asks for two to three lifting sessions a week at Level 3, but the calendar never names them. Slot them yourself on the easier days, after the Monday easy run and the midweek shake-out, keeping the heavy lifts away from the Friday fartlek and the Sunday long run. The pace abbreviations (CV, LTP, HMP, MAS) mean nothing without chapter 4, which converts them into your own per-mile paces from a recent race result. Read that chapter before week one and write the numbers beside each workout. There is also no cut-order for a lost week. If life takes a chunk out of your training, protect the long run and one race-pace session, and let the easy mileage absorb the rest.
What the science supports
Periodization beats constant-load training
The fifteen-week build moves in three-week blocks, each followed by a recovery week. Weeks 1 to 3 anchor a fartlek and hill base. Weeks 4 to 6 turn to short fast intervals that lift aerobic ceiling. Weeks 7 to 9 add threshold and steady-state work, and weeks 10 to 12 rehearse half-marathon pace before a two-week taper. The emphasis shifts cleanly between phases, and that block shape is what the research links to faster race outcomes.

Varied intensity beats steady moderate pace
More than sixteen distinct hard-session shapes rotate through the build. Fartlek, hill repeats, and short fast intervals cover the speed end. Over/under efforts, tempo, steady-state, and half-marathon-pace runs fill out the rest. No two hard weeks read alike. This varied intensity sits beside roughly 75 to 80 percent easy running across each week. That distribution is what the research keeps pointing to as superior to a steady stream of moderate-pace miles.

Race-pace specificity hinges on physiology
Race-pace rehearsal lands in two long-form blocks: 3 by 2 miles at half-marathon pace inside week 7, then 2 by 3 miles at the same pace in week 10. For trained half-marathoners that pace sits close to lactate threshold, so the work doubles as threshold training rather than pace mimicry alone. The plan asks the legs to hold race effort in the volume range they will face on race day.

Long runs are essential for marathon
Long runs progress from 1:20 in week 1 to a 2:30 peak in week 8, with half-marathon-pace blocks tucked inside the back-half long runs. Time on feet past roughly ninety minutes is where musculoskeletal durability and fuel-handling adaptations land, and the plan keeps that exposure regular. Race-pace work eventually rides on top of long-run depth instead of standing in for it.
Toresdahl et al. 2021; Jones & Kirby 2025; Casado et al. 2019
Keep easy days easy, hard days hard
Hard work concentrates on Tuesday and Friday with a Sunday long run, and the days between stay easy or shake-out. That spacing keeps roughly 75 to 80 percent of weekly running at conversational pace, with intensity reserved for two clearly framed sessions. Research on intensity distribution keeps landing on the same point: the easy days need to be easy enough for the hard days to be productive.
