Plan at a Glance
A 2:15 half marathon comes down to one number: 10:18 per mile, held for 13.1 miles. Most half-marathon plans build by stacking long runs and hoping race pace shows up on the day. This one flips the priority. Goal pace gets rehearsed early and often, with a midweek session that puts 3 to 4 miles at 10:18 inside a 5-mile shape from week 1. The long run still grows, peaking at 12 to 13 miles in week 7, but the real engine of the plan is pace memory.
A goal-time half marathon plan asks something different than a finish-the-distance plan. You have to hold a specific pace while your legs fatigue for over two hours, which is where most intermediate runners get caught out. They train at easy effort, race-day adrenaline pulls them out too fast, and things fall apart around mile 9. The fix is simple in concept and hard in practice: spend real time at goal pace before race day, so the body knows what it's signing up for.
Published by Runner's World, the magazine that has covered the sport since 1966, this is a 10-week build for runners already logging 18 to 20 miles a week. You run four days. A midweek pace session and a Friday hills or harder effort day carry the work. A Saturday long run and one easy run round out the week. Cross-training can swap in for any easy day if the legs need a break. Peak volume sits around 27 miles a week, which is lean for a half but workable if your foundation is solid.
Below is the full Buena Vida review of the plan. We score every plan against our 31-point benchmark, which draws from peer-reviewed sports-science research and proven coaching best practices.

Our Review
You can already hold easy miles four days a week, and a sub-2:15 half is the goal. This ten-week build hands you one number, 10:18 a mile, and asks you to know it cold by race day. You run four days. A midweek goal-pace session and a Friday hills or harder effort carry the work. A Saturday long run and one easy day round out the week.
The whole plan is built backward from pace memory. From week 1, goal pace is already in the schedule: 3 miles of it tucked inside a 5-mile run. You stretch that goal-pace block to 4 miles by week 4, drop back through a three-week tempo stretch at 10:01, then return to it for the closing weeks. Most half plans stack long runs and hope race pace shows up on the day. You rehearse the pace first instead. Treat the Friday and midweek sessions as the spine. Your long run tops out shy of race distance in week 7, because the goal-pace work is where this plan actually trains you.
Three gaps are worth planning around before you start. You get no strength on the calendar, so the hip and core work that keeps you durable is yours to schedule. You also get pace targets with no heart-rate or effort backup, so a dead watch leaves you guessing. And you face a shallow taper: week 9 still sits near your peak mileage, and only race week truly steps down. You may arrive at the line less fresh than a longer wind-down would leave you.
This plan suits an intermediate runner with a year of steady training, four days to give, and trust in pace-anchored work. Bring a recent 5K or 10K so 10:18 has a real target, not a guess. If you want a built-in strength block or effort-based pacing, look elsewhere. If your weeks routinely run past 30 miles, a plan with more aerobic volume will serve the distance better.

Structure
Does the plan build you up smartly?
Mostly. Three labeled phases carry you from a goal-pace base through a tempo block to race week, with lighter cutback weeks landing roughly every third week, so the arc is clear and easy to follow. Where it thins out is the wind-down. The taper, the easing-off before the race, barely lowers volume until the very last week, so week 9 still runs close to peak. The build is well shaped on the way up but stops short of a full, graduated easing into the start line.
-
Prevention
Does the plan protect you from injury?
Partly. The week-to-week load climbs cleanly, and cutbacks at weeks 2, 4, and 9 reset it so the build never spikes past a safe level. Every speed day opens with a warm-up mile. What is left entirely to you is the body-side support. There is no strength work anywhere on the calendar and no guidance for catching an injury before it costs you time. For an intermediate runner pushing a pace goal, both are worth adding on your own.
-
Flexibility
What happens when you miss a day?
A missed session here is mostly yours to improvise around. The plan offers one swap, cross-training in place of an easy run, and the two or three rest days each week give a dropped run somewhere to land. Past that, the page goes quiet. There is no order naming which run to protect when a long run gets blown or a week disappears, and nothing on calibrating effort by feel. When life crowds the schedule, you decide what stays and what goes.
-
Readiness
Will the plan deliver race-day fitness?
Mostly, and pace memory is the plan's whole idea. Goal pace gets rehearsed in 8 of the 10 weeks, with a midweek session folding 3 to 4 miles at 10:18 into a 5-mile run from the very start, so 10:18 should feel known by race week rather than new. The long run reaches 12 to 13 miles three weeks out. The soft spots are the shallow taper and a peak around 27 miles a week, which is lean for a half, so the work rests on a thinner base than a higher-mileage build.
-
Variety
Are the workouts varied enough?
Partly. Easy runs and the long run carry the volume, while hills, goal-pace blocks, tempo runs, and a tune-up race fill out the harder end, each spelled out with warm-up, work, and cool-down to a numeric target. What is missing is any track or interval work faster than half-marathon pace. With only goal-pace and tempo as the two harder shapes, the demanding end of the menu stays narrow, so the legs meet less variety of speed than a deeper build would offer.
Plan Strengths
- From week 1 you run 3 miles at 10:18 inside a 5-mile session, and that goal-pace block grows to 4 miles by week 4. Race pace stops being a number and starts being a feel.
- A three-week tempo stretch in weeks 6 to 8 runs you at 10:01, a touch faster than goal. By race day 10:18 reads as a downshift, not a reach.
- Cutback weeks at 2, 4, and 9 pull the long run back so your legs settle before the next climb. Your week-to-week mileage never jumps past the safe range.
- You never run two hard days in a row. The Saturday long run, the midweek goal-pace session, and the Friday effort each sit with an easy or rest day on both sides.
- Every speed day spells out the work rep by rep. You get a warm-up mile, then the goal-pace or tempo block, then a cooldown mile. Each carries a pace to hit.
- Cross-training can stand in for any easy day, so a sore hip on Tuesday means you bike instead of forcing a fourth pounding day.
Weaknesses & gaps
- Strength never reaches the calendar. The durability work that protects a runner stepping toward 13.1 miles is left for you to build and hold to.
- You calibrate the pace yourself. Without a recent 5K or 10K to anchor it, 10:18 is a guess you commit ten weeks to.
- The taper barely cuts. Week 9 still sits near peak mileage, and only race week steps down, so you may toe the line carrying more fatigue than a fuller wind-down leaves.
- Peak mileage lands near 27 a week, lean for a half. A runner used to more will feel the long run a step short of where the distance asks.
- The Friday hills day gives one line of guidance: find the hilliest route you can. No length, no grade, no rep count, so the stimulus shifts with where you live.
- When life interrupts, you decide alone. There is no rule for a missed long run and no sign of which aches mean ease off.
What this plan does not give you
No strength session is ever scheduled. Build it in yourself: two short sessions a week of squats, lunges, and core work go a long way for a runner stepping up to half-marathon volume. The plan also gives you pace and pace alone, with no heart-rate or effort band behind it. If your watch dies or today's 10:18 feels like 9:30 effort, back off and run by feel rather than chasing the number. The Friday hills day comes with one line: find the hilliest route you can. Pick a loop with a hill or two you can run hard for 60 to 90 seconds, jog down, and repeat four to six times. And the taper is shallow, so cut a little extra volume in week 9 yourself if your legs feel heavy heading into race week.
What the science supports
Race-pace specificity hinges on physiology
This plan rehearses half-marathon pace from the first week. You run 3 miles at 10:18 inside a 5-mile shape in weeks 1 to 3, then stretch to 4 miles in week 4. The closing weeks return to 10:18. By race day that pace is a known effort, not a guess made on adrenaline.

Periodization beats constant-load training
The build moves through three labeled phases. Weeks 1 to 5 anchor on goal pace as volume grows. Weeks 6 to 8 shift to faster tempo work while the long run shortens. Weeks 9 and 10 step volume down but hold some goal-pace work. Each phase sets up the next rather than spreading every stress at once.
Bradbury et al. 2020; Tønnessen et al. 2014; Casado et al. 2022
Keep easy days easy, hard days hard
Your hard effort sits midweek and your long run lands Saturday. Everything else is easy running, a rest day, or cross-training. Two to three easy or rest days sit between the hard sessions. That separation lets each hard day land hard and each easy day actually recover you.
Stöggl & Sperlich 2014; Casado et al. 2022; Kenneally et al. 2017
Tapering improves race performance by 2-6%
The last stretch trims volume into race day. Week 9 pulls the long run down to 8 miles and the midweek runs shrink, while a short goal-pace session stays on the calendar. You shed some fatigue while keeping the legs sharp, though the cut is gentler than a longer taper would make it.
Threshold gains are pace-specific
Weeks 6 to 8 add tempo running at 10:01 a mile, a step quicker than your goal. Running just above race pace trains the effort you can hold when fatigue sets in. These runs are meant to be on foot, not a bike, so the gain transfers straight to race day.
