Running Plan Review Buena Vida Run Club's 12-Week Sub-1:35 Half Marathon (5 days)
Plan at a Glance
Somewhere past mile 10 of your last half marathon, the watch still said you were on schedule and your legs had started to disagree. You finished close to the number but not under it. If 34 miles a week is already a normal week for you, and that late fade is the part you want gone, this is written for you.
The answer here is repetition at the exact speed the race asks for. Twice a week you run something hard. One day is repeats at goal pace that grow from half-mile pieces to full miles. The other is threshold running, the effort you could hold for about an hour, or a longer unbroken stretch at goal pace. By race day, a Sub-1:35 effort is something your legs have practiced many times rather than something they meet fresh. The long run climbs from 8 to 15 miles at an easy effort, and a shorter run the next day keeps you moving on tired legs.
The plan asks for 5 days of running and 1 strength session a week, with the weekly total rising toward 58.5 miles. The fast days are not the hard part. Keeping the other 3 days easy enough that the fast days stay fast is. Before the race the running tapers, a stretch of lighter weeks, so you start rested instead of worn.
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
If 5 runs and about 34 miles already fill your normal week, 12 weeks on that schedule can make ⟦hm:7:12⟧ feel like your own pace. Wednesday and Friday stay free of running. The trade is that the miles crowd into fewer runs, and by the peak a Monday easy run reaches 11 miles.
The idea underneath is that goal pace is learned in pieces before it's held whole. Your Tuesday repeats at ⟦hm:7:12⟧ start as 6 half miles and grow to 6 full miles, with easy jogs between. Early in the build you also hold it for 5.5 unbroken miles, and a shorter 2.5-mile version returns in the taper. By race week, goal pace has stopped being a number you chase and become an effort you recognize.
The gaps sit mostly in the climbs out of the lighter weeks. After the first cutback your week jumps from 31 to 44.5 miles, and that long goal-pace run arrives with it. Coming out of the second, the week rises from 43 to 58.5 and carries a 15-mile long run, longer than a half needs. With 2 hard days in 5, little easy running is left to absorb a session run too fast. Strength stays one unchanging weekly slot, and the 6 × 1 mile set repeats into the taper.
Choose this if you race halves within a few minutes of the goal and already handle weeks in the 50s without trouble. If you'd rather spread the running thinner, more days will sit easier. Otherwise, this is a strong 12 weeks to commit to.

Structure
Does the plan build you up smartly?
Each hard format gets its turn to grow before the next takes over, which suits a short build. Repeats lengthen from 0.5 mile to 0.75 and then to a full mile, while threshold runs stretch from 3.5 miles to 6. Weekly running climbs from 34 to 58.5, with a lighter week after each 3-week climb. A 3-week taper then halves the running and keeps the hard sessions in place.
-
Prevention
Does the plan protect you from injury?
Yes, with one gap to plan around in the climbs out of the cutbacks. After the first, your week rises from 31 to 44.5 miles and adds a new format, 5.5 unbroken miles at ⟦hm:7:12⟧. After the second, it rises from 43 to 58.5. In those weeks, trim the Monday easy run if your legs stay heavy and keep the hard sessions whole. Outside them, hard days never touch and nearly every hard session opens with an easy warm-up.
-
Flexibility
What happens when you miss a day?
Losing an easy day barely registers, but losing a weekend costs more, since the long run and the Sunday run carry about 40% of the week. Protect the long run and the 2 hard days, and let the Monday run go first. Wednesday and Friday carry no running, so a session pushed off by a busy day has somewhere to go, as long as it doesn't sit beside another hard run. If a whole week disappears, repeat it rather than stepping into the next climb. Beyond that, the reshuffling is left to you.
-
Readiness
Will the plan deliver race-day fitness?
Two rehearsals bracket the race-pace work, 5.5 unbroken miles at ⟦hm:7:12⟧ early in the build and 2.5 more in the taper. Between them, repeats stretch to full miles and threshold runs reach 6, so the race asks for no effort you haven't already held. A long run on Saturday and a medium-long run on Sunday teach your legs to keep going when they're already tired. The 15-mile run goes past what a half needs, though at easy effort it takes little away. A 3-week taper keeps the hard sessions and halves the running, so you start fresh.
-
Variety
Are the workouts varied enough?
Something new turns up in every phase, from goal-pace repeats to a progression run and 2 race simulations. Repeats grow from half miles to three-quarters to full miles, and the threshold run changes length almost every time it appears. The 6 × 1 mile set does come back 4 times through the peak and taper. That gives you a fixed yardstick for how goal pace feels as your legs freshen. Strides show up only in the shake-out before the race.

A time goal changes how a training block feels, mostly because the number is now written down. The easy weeks before this one did their job, and the calendar now starts asking for more. These days ask you to learn the efforts rather than prove them. The faster sessions may feel a little clumsy at the start, more a matter of finding the gears than lacking them. Keep everything else slow enough to talk through. Over 12 weeks, the runners who reach the start line healthy are usually the ones who held back early.
M 5.5mi Easy Run
5.5 miles easy. The opening run of a goal block tends to carry more weight in the head than in the legs. Run it at a pace that leaves room to talk, and skip the urge to check whether you are fit enough. Tomorrow has faster work in it, and that is where any testing belongs.
Tu Intervals: 6×0.5mi @ ½ Marathon
Warm up 2 miles, run 6 × 0.5 mile at goal pace (7:12/mile) with 400 m easy jogs between, and cool down 2 miles. Goal-pace repeats this early in a block often feel almost too easy, and that is the right read. The reps are short so you can learn the rhythm without strain. Hit the pace, not a few seconds under it. The trap is creeping faster with each rep because the effort feels cheap. If rep 6 matches rep 1 on the watch, the session did its job.
W Strength Training
Th 6.5mi Threshold Run with 3.5mi @ Threshold
Warm up 1.5 miles, run 3.5 miles at threshold, and cool down 1.5 miles. A sustained threshold block takes some calibration, so the opening mile of it may feel uncertain. Settle at the effort you could race for about an hour and let the pace follow. Fresh legs make threshold feel like it could go faster, and for a while it could. The back half should feel like steady work with controlled breathing and no fade.
F Rest
Sa 8mi Long Run
8 miles easy. The opening long run of a goal block usually feels easier than expected, and that ease is the point, not a sign to push. Keep it conversational the whole way, even if the legs wake up late and want to press in the closing miles. Tomorrow's run sits on top of this one. Finish with enough left that Sunday feels like running, not repair.
Su 5.5mi Medium-Long Run
5.5 miles easy. Yesterday's 8 miles are still in the legs, and the opening stretch may feel stiff. That is why this run exists: easy running on tired legs is close to what the back half of a half marathon asks. Keep it truly easy and let it loosen on its own schedule.
The legs are starting to register what a pair of hard days each week asks of them. Heavy calves on the morning after, a sluggish opening mile on an easy day: both are ordinary at this stage. Recovery between efforts happens on the easy days and in sleep, which makes those two things part of the training rather than a pause in it. Let the easy runs be as slow as they need to be. Nobody is grading them.
M 6mi Easy Run
6 miles easy. A Monday after a full weekend usually starts heavy. Give the legs a mile to come around before judging the day. Keep the effort relaxed enough that tomorrow's repeats get your best legs.
Tu Intervals: 6×0.5mi @ ½ Marathon
Warm up 2 miles easy, then 6 × 0.5 mile at 7:12/mile with 400 m jogs, and cool down 2 miles. The same session again, and repeating it is how you learn what changed. The pace should feel a little more automatic and the jogs a little less needed. Run each rep on goal pace and no quicker, even when rep 4 feels like it could go faster. Holding a pace you could beat is the skill being practiced. Restraint here is worth more than a fast split.
W Strength Training
Th 8mi Threshold Run with 4mi @ Threshold
Warm up 2 miles, hold threshold for 4 miles, and cool down 2 miles. Half a mile more at threshold than the previous one, and that half mile is where it gets interesting. Most runners find mile 3 is where the effort stops feeling free and starts needing attention. Stay there without forcing it. Breathing should be steady and rhythmic, never ragged. If the pace slips a few seconds at the end while the effort holds, that is fine.
F Rest
Sa 9mi Long Run
9 miles easy. This is the longest run of the plan so far, and the extra mile tends to show up in the last 2. Start slower than feels natural and let the pace settle on its own. Most runners drift faster in the middle without noticing, so check the effort once or twice. Easy here is a pace you could talk through from start to finish, and it should still feel that way near the end.
Su 5.5mi Medium-Long Run
5.5 miles easy. The legs know about yesterday, and that is fine. Run at whatever pace keeps the breathing relaxed, even if it is slower than your usual easy. Nobody needs to see this split. The run counts for the time on tired legs, not the speed.

Plan Strengths
- In the middle miles of race day, ⟦hm:7:12⟧ should feel practiced, with 5.5 unbroken miles of it already behind you.
- You'll learn to keep running on used legs, since a medium-long run follows every long run the next morning.
- Threshold runs stretching to 6 unbroken miles make the hard middle of a half feel like ground you've already covered.
- Not once do 2 hard sessions sit on back-to-back days, so each repeat set and threshold run gets your best effort.
- Over the last 3 weeks the running halves while the goal-pace work stays, so race week feels light without feeling unfamiliar.
Weaknesses & Gaps
- Injury risk climbs coming out of the 2 cutbacks, when your week jumps from 31 to 44.5 miles and from 43 to 58.5.
- You meet the 5.5-mile goal-pace run in that same rebound week, so a new hard format arrives on top of the jump.
- More tiredness than a half requires comes from the 15-mile long run, with a 9-mile run waiting the next morning.
- If a hard day goes too fast, there's little easy running to absorb it, since 2 of every 5 runs are hard.
- Strength work stalls at one unchanging 30-minute slot a week, with nothing to build it up as the running climbs.
- Your legs get almost no speed above goal pace, since the 6 × 1 mile set repeats 4 times late on and strides appear once.
What's missing
A few changes on your own would close most of the gaps. In the week right after each cutback, shorten the Monday easy run so the climb back up is gentler, and save the full week for the one after. Stop the 15-mile run at 14 and add that mile to the Sunday run instead. A handful of strides, short relaxed bursts of speed, after one Monday run a week would give your legs some pace above goal. The weekly strength slot needs a plan that grows across the build, which you'll have to bring yourself or get from a coach. The plan also never says what to do when a week goes sideways, so decide ahead of time which session gives way first.
What the science supports
Rapid volume jumps raise injury risk
Injury risk climbs when a week runs far past what your legs have recently handled. Pushing more than about 50% past the recent average raises the risk 2 to 3 times. Ordinary weekly rises here stay within about 10%, from 34 miles up through 40.5 before the first cutback. Even the steepest climbs out of the lighter weeks stay well short of that 50% mark against the weeks before them.
Higher weekly mileage lowers injury risk
Runners who build to higher weekly mileage gradually get hurt less often, not more. One large study of runners' watch data found that people running under about 15 miles a week had more injuries than those running more. You start this plan at 34 miles, already well above that line. From there the week climbs toward 58.5 in steps, with a lighter week after each climb.
Race-pace training pays off near your threshold
Practice at race pace pays off most when that pace sits near threshold, the effort where easy running turns hard. For a trained runner aiming at ⟦hm:7:12⟧, goal pace falls close to that line. Time spent there teaches race rhythm and lifts the threshold itself. That makes the 58 miles of goal-pace work in this plan more than rehearsal.

Varied intensity beats a steady moderate pace
Mixing clearly easy days with clearly hard sessions builds endurance better than running at a steady medium-hard effort most days. In studies, runners on that mix could hold a hard effort 12% to 17% longer. Here the 2 hard days are clearly hard, goal-pace repeats and threshold runs. The long run and the Sunday run stay at an effort you could talk through.

Strength training makes running more efficient
Strength training helps trained runners use 2% to 8% less energy at the same pace. That effect rivals what extra easy miles would give. One to two sessions a week is the usual dose for a distance runner. This plan books one every Wednesday, between the 2 hard days and never beside one. It leaves strength out of race week, so your legs reach the start fresh.
