Plan at a Glance
Sub-1:45 is a pace before it is a time, and this plan treats it that way. Nearly every Tuesday you run goal pace in repeats, starting with a few half-miles and growing to 8 full miles of it with short jogs between. Your longest run carries 3 goal-pace miles in its middle, after 6 easy ones. By race morning the pace should feel like somewhere your legs already know how to go, not a number you have to reach for.
The rest of the week is built so those Tuesdays land. Thursday is a sustained threshold run. Sunday's medium-long run lands on legs still carrying Saturday's long run, which is about as close as training gets to the last few miles of a half. Monday is easy, Wednesday is strength, Friday is off. Most of your running stays at a pace you can talk at, and the plan means it.
This is for a runner who has raced a half, sits within reach of 1:45, and already runs about 33 miles a week over 5 days. Mileage climbs into the mid-50s in the biggest week, with lighter weeks along the way to absorb it.
The moment that decides how it goes comes on the Tuesday of that biggest week. The weekend's long run is still in your legs, and the first mile at goal pace will feel easy, easier than it has any right to. You will want to run it fast. Run it at goal pace instead, like you plan to enjoy the last one. The rest of that week, all the way to your longest run, runs on the legs that a controlled first rep saves.
The review below is Buena Vida's full assessment of the plan. We grade every plan against the same detailed, 30-point benchmark. Each measure draws from peer-reviewed sports-science research and proven coaching best practices.

Our Review
If your last half came apart somewhere after the halfway mark, this plan is aimed squarely at that. Its one clear idea is to rehearse goal pace often enough that it stops feeling like a stretch: goal-pace repeats every Tuesday except the first cutback, lengthening as the build goes on, and a long run with goal pace inside it. Race-pace work and threshold work are different kinds of training. Either is a reasonable bet for a recreational runner, so building the plan around goal pace is a sound choice. Around that core, the plan does the unglamorous things right: an easy Monday, Friday off, and cutbacks in weeks 4 and 8 before a real taper. The gaps are small: one sharp step up after the first cutback, and a long run that climbs unevenly to a peak a little past what the half needs. If sub-1:45 is the goal and five days a week fits your life, this is a plan to trust.

Structure
Does the plan build you up smartly?
In clean, distinct steps. The plan moves through four phases with distinct jobs: two base weeks to settle into a 5-day rhythm, a six-week Sharpen block where the work points at goal pace, a taper week, and race week. Weekly mileage climbs from about 33 to about 56 in the biggest week. Training in distinct phases tends to beat holding one steady load, and this plan has its phases in the right order.

Prevention
Does the plan protect you from injury?
A sound build, with its hard days well spaced and well wrapped. Wednesday's strength day keeps Tuesday's reps and Thursday's threshold run apart, and each of the 16 hard sessions is wrapped in a warm-up and a cool-down. That is the pattern that keeps a build like this healthy. Cutback weeks at 4 and 8, with a light race week to finish, give your legs regular relief from a build that would otherwise keep piling up. Outside the rebound after the first cutback, the week-to-week rises stay modest. The soft spot is week 5, the first week back from the cutback. Mileage jumps, the long run goes from 8.5 to 12.5 miles, and the Tuesday reps stretch to full miles, all in the same week. Big jumps in load tend to raise injury risk. Run week 5's easy days as slowly as any in the plan, and if something starts to niggle, trim the Sunday run first.

Flexibility
What happens when you miss a day?
The plan has already made the hard choices for you. Hold on to the goal-pace reps, the threshold run and the long run, because those three carry the goal. Monday's easy run and Sunday's medium-long run give way first, and strength is the lowest priority of the week. Friday is already a rest day, which gives the week some slack, but don't use it to squeeze a missed threshold run in right before the long run. Let a missed hard session go and run the next one as written. If you lose a few days to illness, come back with a couple of easy days and then pick the plan up wherever the calendar is, without trying to make up the lost miles.

Readiness
Will the plan deliver race-day fitness?
Squarely. The back half of a half marathon is where runners just over 1:45 usually lose the goal, and this plan aims straight at it. Race-specific work runs through almost every week and grows toward the race, on Tuesday at goal pace and on Thursday at threshold. Your longest run puts goal pace on legs that already have 6 miles in them, which is the closest rehearsal of the late race you will get before the day. Then, as the mileage comes down, the Tuesday sessions reach their longest, 8 miles at goal pace in each of weeks 8 and 9, so you carry the rhythm into the taper rather than leaving it behind. Peak mileage sits comfortably inside what this goal asks, and a structured taper like this one tends to help runners race better than training straight through. The one small gap is the long-run sequence. It rises and falls in bigger steps than it needs to, and its 15-mile peak runs a little past what a half usually calls for.

Variety
Are the workouts varied enough?
Wide-ranging within its focus. The week holds easy runs, a medium-long, a long run, goal-pace repeats and a threshold run, and the Tuesday reps change length every week or two, so no session feels like a copy of the last. Most runners believe a rep run faster than goal pace banks a little extra fitness. This plan disagrees, and its notes say so plainly: if the early reps drift fast, ease back, because the reps exist to build time at goal pace. That is why its biggest dose of goal pace comes in a lighter week, after total mileage has started to fall. The faster running stays narrow, at or near the pace you are training to race, so every hard minute goes to the pace the race will ask for.

The build toward your half marathon starts here. This week asks less than most, and that is by design. Hold the easy runs at a truly conversational effort and let the harder work introduce itself on its own schedule. What matters most right now is showing up and building a rhythm the coming weeks can run on. Resist the urge to chase fitness you have not earned yet. The goal you wrote down is reachable, and it is reached by stacking ordinary weeks, beginning with this one.
M 6mi Easy Run
6 miles easy to open the plan. Aim for a pace where talking stays effortless. The early easy miles build the aerobic base every later session draws on. If you finish feeling fresh and barely worked, it did its job.
Tu Intervals: 4×0.5mi @ ½ Marathon
First key session of the plan. Half-mile reps to introduce goal pace. 2 mile warmup, then 4 x 0.5 mile at half marathon goal pace with 400 m recovery jog, then 2 mile cooldown. Pace each rep on feel, not the watch. The goal is to learn what 7:57/mile feels like, not to check it. The first rep usually feels faster than the others. That's because it isn't. Repeats break hard running into pieces the body can absorb, building speed without breaking form.
W Strength Training
Th 6.5mi Tempo Run with 3.5mi @ Tempo
Warm up 1.5 miles easy, then run 3.5 miles at threshold effort for the first time in the plan, and cool down 1.5 miles. Threshold is the pace you could hold for about an hour if forced. Slightly slower than goal half pace today (7:57/mile is too fast for threshold at this stage). Settle into the rhythm in the first half mile, then hold there. Sustained efforts like this raise the pace you can hold before breathing becomes the limiter. Comfortably hard means a few words at a time, never full sentences.
F Rest
Sa 8mi Long Run
Long run, 8 miles. The first long run of the plan is the starting line for everything that follows. Steady aerobic effort. The legs will feel heavier in the final 2 miles than the first six. That's the long-run signal showing up. Run the second half by feel rather than pace. Over the coming weeks the long run climbs to 15 miles.
Su 5.5mi Medium-Long Run
Medium-long, 5.5 miles. The first Sunday-after-long of the plan. The legs will start sluggish and stay sluggish. That's the point of the day. Conversational pace, lower than the easy-day default. Today is about teaching the legs to keep moving when they don't want to.
Early in any half plan, the running can seem to do less than it should. The body changes on a slow clock, and most of what is changing right now will not show up on a watch for another few weeks. The body is laying capillary density and mitochondrial capacity that the harder work later will lean on. Stay patient with the conversational running. It is doing the work the faster days will eventually take credit for.
M 6.5mi Easy Run
Recovery from the long-and-medium-long pair on Saturday and Sunday. Run by conversation, not by watch. The legs will feel heavier this morning than the pace says they should, and that's the cost of stacking the two long days.
Tu Intervals: 5×0.5mi @ ½ Marathon
2 mile warmup, then 5 x 0.5 mile at half marathon goal pace with 400 m recovery jog, then 2 mile cooldown. It is the 4 × half-mile set with a rep added. The fifth rep is the only new one in this session. The legs should reach it as fresh as the second. If pace climbs by rep 4, you started rep 1 too fast. The rest between reps is what lets the work stay fast from first to last.
W Strength Training
Th 4.5mi Easy Run
Easy 4.5 miles at conversational effort. The body doesn't get faster from hard days alone. It gets faster from hard days the body can recover from. Today is the recovery that lets the next harder session go well. Run by feel rather than pace. The legs will tell you the right speed.
F Rest
Sa 9mi Long Run
Long run, 9 miles. The aerobic base keeps building. Steady effort. The pace at mile 8 should match the pace at mile 2. If it doesn't, the opening miles were too fast.
Su 6.5mi Medium-Long Run
Medium-long, 6.5 miles. The first 2 miles are the hardest of the day on legs that ran long yesterday. If you stay relaxed through them, the rest follows. This second effort on tired legs teaches the body to keep working when fatigued, which is exactly what the back half of a half marathon asks.

Plan Strengths
- Goal pace is rehearsed 10 times: 9 Tuesday sessions and the peak long run.
- Close to 80 percent of the running is easy, and Friday off keeps Thursday's threshold run clear of Saturday's long run.
- Cutback weeks in weeks 4 and 8 and a stepped taper give you a regular break from the build, so the load never piles up for long.
- Every hard session carries a note that tells you what it is for and how to pace it.
Weaknesses & Gaps
- Week 5 brings a big step up in load right after the cutback, with more total mileage and full-mile reps arriving together.
- The long-run sequence moves in big steps, most sharply from 8.5 to 12.5 miles coming out of the cutback.
- Your longest run reaches 15 miles, a little past what a half usually calls for, so run its easy miles patiently.
What's missing
A few optional additions suit this plan if they suit you. Once the base weeks are done, 4 to 6 short, relaxed strides after Monday's easy run cost almost nothing, and they give you regular, low-risk practice at short, fast running. If your race course climbs, run a Monday easy run on a rolling route a few times during the Sharpen weeks and take the hills at the same easy effort. With the Tuesday goal-pace work growing to 8 miles at a time, the plan rehearses race effort without a tune-up race. If you want one to settle your nerves, use week 3: swap a race in for that week's 5 x 0.75 mile reps, hold it at goal effort instead of racing flat out, and keep the rest of the weekend easy. Finally, the week 3 note tells you how to tell normal soreness from sharp pain, but not what to do about a low-grade ache that lingers. Treat a niggle like that as a warning worth acting on. A few days of clearly less running is a sensible precaution, and it doesn't have to mean a full stop.
What the science supports
Shifting training emphasis beats unchanging training
The 10 weeks break into four phases, each with a distinct purpose. Three-week builds open the plan and follow the week 4 cutback, adding mileage and skill. Week 7 brings the peak long run and highest total volume. Week 8 eases off, then a taper week and race week drop volume further while intensity work stays in place. Shifting the emphasis toward race work as the day nears is what top coaches do, and in trials it tends to beat an unchanging mix by a small margin.

Easy miles do most of the work
About 79 percent of the running here sits at conversational effort, slow enough to hold a full sentence. Monday runs and the weekend long and medium-long runs stay easy almost every week, leaving Tuesday's goal-pace intervals and Thursday's threshold tempo, the comfortably hard effort you could hold for about an hour, as the hard days. Elite distance runners do about 80 percent or more of their running at an easy effort. That base is what carries the harder work and lets the body adapt to it.
A real taper sharpens you for race day
Week 8 eases off the peak, and week 9, the taper proper, sits about 30 percent below week 7. Tuesday's 8 x 1 mile at goal pace and a shorter Thursday threshold run stay on the calendar through both. Race week keeps a single 3 x 1 mile tune-up, then easy running and strides. A taper that cuts volume while keeping some speed improves race-day performance over training straight through.
Threshold or race pace: neither proven better
Goal-pace mile reps start small (4 half-mile efforts in week 1) and grow to 8 full miles by week 8. In week 7, 3 miles at race pace live inside the 15-mile long run, after 6 miles of easy warmup. By race day, goal pace has shown up in 10 separate sessions. Race-pace work and Thursday's threshold run are different kinds of training. No study shows one beats the other for recreational runners, so a week that holds both covers each.

Fixed plans need built-in lighter weeks
Weeks 4 and 8 bring the mileage down on schedule, from about 40 to 30 and then from 56 to 47, and race week drops it again. Load that keeps piling up without a break is linked to more injury and illness. On a fixed plan with no coach adjusting it, a lighter week written into the calendar is the one form of relief that needs no judgment or equipment.
