Running Plan Review Buena Vida Run Club's 10-Week Sub-1:45 Half Marathon (5 days)
Plan at a Glance
Eight minutes and one second per mile is what sub-1:45 in the half marathon actually means. This plan puts you on that exact pace ten different times before you ever pin a race number on. Goal-pace mile reps grow from four half-mile efforts in week one to eight full-mile reps by week eight. By race week the rhythm of 7:57 is something your legs recognize, not something you have to dig for.
The jump from a 1:50 half to a 1:45 half is smaller than it looks on a clock and larger than it feels in training. Twelve seconds per mile is the gap. Most runners stuck above 1:45 are not slow. They are under-mileaged or under-rehearsed at the pace, and the back half of the race is where both shortages show. Closing the gap takes weekly volume to grow aerobic capacity and enough time at goal pace that it stops feeling like a stretch.
Buena Vida Run Club built this 10-week, five-day-a-week build for the runner with a recent half between 1:50 and 1:55 and a comfortable 30 to 35 mile base. Mileage opens at 32 and peaks at 52 in week seven. Two harder running sessions sit midweek, with a long run and a shorter Sunday run stacked back to back on the weekend. One strength session holds its slot from week one through race week. A two-week taper closes the plan.
The review below is Buena Vida's full assessment of the plan. We grade every plan against the same detailed, 31-point benchmark. Each measure draws from peer-reviewed sports-science research and proven coaching best practices.

Our Review
You're the runner with five mornings a week to give to running and a recent half between 1:50 and 1:55. This plan is the work that takes you from there to sub-1:45. Five running days plus one strength day. Two harder running sessions and a long-plus-medium-long stack on the weekend. The shape concentrates the work without crowding recovery.
Sub-1:45 in the half marathon is 7:57 per mile, and you'll touch that pace in two specific places. Your goal-pace intervals grow from four half-mile reps in week 1 to eight mile reps by week 8. In week 7, you run three miles at 7:57 inside the 15-mile peak long run, after six miles of warmup. By race day, you've rehearsed 7:57 across ten different sessions. The Sunday medium-long after each Saturday long is where your legs learn that pace when the easy reserve is already spent.
It fits a runner already running 30 to 35 miles a week comfortable with two harder sessions per week. If your base is under 25 miles, build aerobic base for four to six weeks first. You'll open at 32 miles and climb to 52 by week 7. The cutback at week 4 is real, and the two-week taper holds race-pace memory while volume drops. Strength keeps its slot from week 1 through race week. The phasing and the run-type variety are the standouts here.

Structure
Does the plan build you up smartly?
Every week has a job, and the calendar shows you what it is. Base, Sharpen, Peak, Taper, and Race Week each run a distinct block, and every three-week build closes with a deload before the next one stacks on top. The load tops out in week 7, then the long run starts stepping back down to meet race day. From the first week to the last, nothing about the order is left to chance.
-
Prevention
Does the plan protect you from injury?
Mostly, with one rough seam to know about. About 80 percent of weekly miles stay easy, hard days never land back to back, and a strength session holds its slot every single week to keep the legs durable for the late miles. A deload follows each three-week build, which keeps the worst week's training load just under the line coaches watch. The one bump: the jump out of the week 4 cutback into week 5 is steep, though the deload on either side of the build is there to absorb it.
-
Flexibility
What happens when you miss a day?
Miss an easy run and the plan absorbs it without a ripple. Miss the Saturday long run and you are improvising. Every workout carries a priority, so when a week shrinks you know the long run and the goal-pace session come first and the recovery miles come last. What the plan does not hand you is a rule for slotting a missed long run back in. That call stays yours.
-
Readiness
Will the plan deliver race-day fitness?
The plan rehearses race day until 7:57 per mile feels routine. Goal-pace reps grow from four half-mile efforts to eight full miles, the long run climbs to 15 miles with three of them run at goal pace, and threshold work stretches week over week. A two-week taper drops the volume while holding the pace work, so the legs arrive fresh rather than flat. Race week opens with a short tune-up, then nothing but easy miles and strides into the start line.
-
Variety
Are the workouts varied enough?
Six kinds of running keep the ten weeks from ever feeling like the same workout twice. Easy runs, medium-long runs, long runs, threshold (the pace you could hold for about an hour), goal-pace intervals, and strides each show up with a clear role. The interval session itself never sits still, growing from four half-mile reps in week 1 to eight one-mile reps by the taper. Goal-pace work stays at half-marathon pace and no faster, which is exactly what a time goal at this distance rewards.

Ten weeks starts here. The first one is rarely the hardest, and that is by design. Hold the easy efforts at honest conversational level and let the harder work introduce itself on its own schedule. What matters most right now is showing up, building the rhythm that the next nine weeks will run on, and resisting 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
First run of the plan. Aim for a pace where talking stays effortless. The early easy miles build the aerobic base every later session draws on. If the run feels forgettable afterward, it did its job.
Tu Intervals: 4x0.5mi @ 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 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
First threshold run of the plan. 1.5 mile warmup, then 3.5 miles at threshold effort, then 1.5 mile cooldown. Threshold is the pace you could hold for about an hour if forced. Slightly slower than goal half pace today (7:57 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. First long run of the plan. The starting line for everything that follows. Steady aerobic effort. The legs will feel heavier in the final two miles than the first six. That's the long-run signal showing up. Run the second half by feel rather than pace. The long run starts here and climbs from 8 to 15 miles by week 7. Today sets the rhythm that climb is built on.
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.
The first stretch of any half plan is quieter than it feels like it should be. Aerobic adaptations move on a slow clock, and most of what is changing inside the engine 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 sharper 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: 5x0.5mi @ ½ Marathon
Second touch of goal pace. One more rep than last week, same distance. 2 mile warmup, then 5 x 0.5 mile at half marathon goal pace with 400 m recovery jog, then 2 mile cooldown. 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 sharp 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 land. 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 aerobic system to work under fatigue, which is exactly the adaptation a half marathon demands.

Plan Strengths
- Stacking a 9.5-mile Sunday on top of Saturday's 14-mile peak long teaches the legs what miles 10 to 13 of race day will feel like. The body has a memory of how to keep moving through it.
- The peak long run in week 7 carries three miles at race pace in the middle. The back-half rhythm of race day already lives in your legs from that day.
- Each weekend except deload, the long-and-medium-long stack lands on consecutive days. Fatigue you train through becomes fatigue you race through.
- Six session types and an interval format that grows by phase keep the work varied. Your legs meet the same 7:57 from several angles before race day.
- Across two weeks of taper, volume drops while intervals stay on the calendar through race week. The pace memory doesn't fade.
- Hard-day separation holds across every build week. The midweek tempo and Saturday long never share fatigue.
Weaknesses & Gaps
- Strides show up only in race week. Earlier weeks would benefit from regular strides to maintain leg speed alongside the goal-pace work.
- Coming out of the week 4 cutback, volume jumps sharply into week 5 before the build settles. Watch how the legs absorb that first heavy week back.
- Five running days plus one strength day leaves the legs only one true rest day a week. Sleep and food have to be excellent, with little margin if either slips.
What's missing
Strides show up only in race week, when leg speed gets squeezed for time. If you can, fold four to six 20-second strides into one easy run a week from week three onward. They cost almost nothing and protect the snap you will want for the last mile. Coming out of the week 4 cutback, the jump into week 5 is steep, so treat that first week back as a feel-it-out week rather than a week to chase numbers. Five running days plus one strength day also leaves only one true rest day a week, and sleep and food have to be excellent for ten straight weeks. If either slips, the cutback week is where to absorb the cost and the place to be honest about it. None of this is a hole in the plan so much as a set of edges to manage as the mileage peaks.
What the science supports
Periodization beats constant-load training
The 10 weeks break into five phases, each with a distinct purpose. Three-week build blocks during the base and sharpen phases add mileage and skill. Week 7 brings the peak long run and highest total volume, followed by two weeks of taper where volume drops while intensity work stays in place. The structure allows the body to build fitness across the early weeks, sharpen it in the middle, and arrive at the start line rested. Moving through these phases rather than holding the same week-to-week rhythm is what gets you to the finish line stronger.

Polarized training beats threshold-dominated
About 80 percent of your weekly running sits at conversational effort. Two hard sessions land each week during the build (Tuesday intervals at goal pace and Thursday at threshold) and Saturday's long run stacks with an easy Sunday afterward. Wednesday and Monday are easy. This separation lets hard sessions have impact without demanding constant intensity, and it's the approach that works best for trained runners like you.
Stöggl & Sperlich 2014; Casado et al. 2022; Kenneally et al. 2017
Tapering improves race performance by 2-6%
Week 8 opens the taper. Volume drops roughly a third from the peak, but Thursday's threshold run and Tuesday's goal-pace intervals stay on the calendar. Week 9 tightens further. By race week, intervals shrink to a single 3x1-mile tune-up and then rest days and strides. The two weeks let the cumulative fatigue clear while your legs remember what 7:57 per mile feels like.
Race-pace specificity hinges on physiology
Goal-pace mile reps start small (four half-mile efforts in week 1) and grow to eight full miles by week 8. In week 7, three miles at race pace live inside the 15-mile long run, after six miles of easy warmup. By the end of the build, you've rehearsed 7:57 a dozen times across ten different sessions. For a sub-1:45 half, that pace lands right at the threshold that trained runners like you can hold for the whole distance.
