Plan at a Glance
A sub-2 half marathon is a pace problem more than a distance problem. Most runners chasing it can already cover 13.1 miles. What they can't yet do is hold one particular pace for all of them, with no breaks and tired legs in the closing miles. Nearly every hard session runs at your goal pace, and the plan's job is to make that pace feel ordinary.
It teaches the pace two ways. On Tuesdays you meet it in pieces: half-mile and three-quarter-mile repeats with a short jog between, enough of them that one Tuesday holds more goal-pace running than any single unbroken block in the plan. On Thursdays you hold it unbroken, in a tempo run that grows a little each time. Late in the build the Tuesday repeats fuse into one continuous stretch, and your longest run carries a block of goal pace in its middle. By race day the pace is no stranger. It's somewhere you've been many times.
Around those two days, the running is easy. Mondays and Wednesdays are runs you could talk through, with a few short strides to finish most Mondays. Saturday is the long run, nearly always at that same talking pace, and Friday holds a strength session. This version gives the work more room than the shorter ones do. It doesn't climb to a bigger peak. Instead it splits the build into three blocks with a lighter week after each, so the same work has longer to settle, which suits a runner more likely to arrive hurt or flat than undertrained. Arrive able to run about 17 miles a week on five days. The plan starts right there, with easy running only until the rhythm of five days feels normal, and then goal pace arrives.
Below is the full Buena Vida review. Every plan is held to the same detailed, 30-point benchmark, with each measure traced back to peer-reviewed sports-science research and proven coaching best practices.

Our Review
What sets this plan apart for a sub-2 half is focus. It picks one pace, your goal pace, and comes at it from every side until holding it for 13.1 miles feels like something you've already done. The easy running stays easy, the hard days are kept apart, and the taper trims the running without letting the pace go stale. The high point is a 14-mile Saturday with 3 miles at goal pace inside it, three weeks before race week.
There is one real soft spot to plan around: the first week back from the first lighter week climbs much faster than anything else in the plan. Go into that week planning to hold back, and keep the easy days slow around it. The other gaps are smaller. The first interval session and the first tempo arrive together, in a week that also adds mileage, and every hard session runs at the same pace, so the plan doesn't build a gear above it.
If you have 5 days a week and want goal pace to feel familiar long before race morning, this is a strong pick.

Structure
Does the plan build you up smartly?
Largely, though it trains one thing from start to finish. Goal pace arrives after 2 easy weeks and owns every hard session from then on. That keeps the aim clear, but there is no speed phase or hill phase before it, so the race work has no earlier block of its own to grow from. From the first 7 half-mile repeats to the race-week Monday run, each of the 19 hard sessions is written out warm-up to cool-down, with a line on why it's there.

Prevention
Does the plan protect you from injury?
Careful in all but one week, where too much arrives at once. About 80% of the running is easy, and through the build Wednesday's easy run always separates Tuesday's session from Thursday's tempo. Those easy days carry more of the plan than they look like they do. Take the Wednesday of the biggest week, between a 6-mile continuous run at goal pace and a 3-mile tempo, with a long run still to come. By then you'll feel fit, and a runner who feels fit tends to run that Wednesday at "comfortable" instead of at a talking pace. Do that and Thursday turns ragged and Saturday becomes survival. Every fourth week through the build is lighter, with less mileage and no hard sessions. Many runners want to add a run back, but that week is the relief the block before it needs. The week to watch is the first one back from the first lighter week. The intervals return with an extra rep, the tempo grows and the first 8-mile long run arrives, all at once. Big jumps in running tend to raise injury risk, and many injuries that look like slow wear actually start suddenly after one. So run that week at the gentle end of every target. If something starts to ache, trim rather than drop: take a rep or two off Tuesday and cut Saturday's long run short, keeping both sessions in their place, then step back into the plan as written once the ache has settled. The week goal pace first arrives asks for a milder version of the same care, with the first repeats run on the easy side of the target. Week 6 deserves it too, since Tuesday's repeats come to about 12 miles, well past any run in the month before.

Flexibility
What happens when you miss a day?
With every session in a clear order, the plan does most of the deciding for you. Tuesday's goal-pace work, Thursday's tempo and Saturday's long run come first, the easy runs second and strength third. Lose a day and you protect those three and let an easy run go. Because an easy day always sits between the hard ones, a missed day never stacks two hard sessions together unless you try to make one up. Don't. The plan's own advice for a heavy-legged week is to run the hard day at the gentler end of the target and make the long run the priority.
-
Readiness
Will the plan deliver race-day fitness?
A full rehearsal, with a taper to match. Peak mileage and the long run are right for a half marathon, and the race-specific work grows the way it should. Goal pace starts as short tempos and half-mile repeats, then builds late in the build to a 4-mile continuous block and, in the biggest week, a 6-mile one. That same week, the 14-mile long run carries 3 miles at goal pace in its middle: a true rehearsal of holding the number on tired legs, worth running in your race-morning kit and shoes. The taper then trims the running over the last three weeks while keeping a short goal-pace run in each one. Less running at the same pace gives the legs a chance to rest while they keep the rhythm.
-
Variety
Are the workouts varied enough?
Expect Tuesday to keep changing shape. You'll run easy runs with strides, interval repeats, tempo runs, continuous pace runs, long runs and a long run with goal pace inside it, and the repeats change shape as the build goes, from 7 half-miles to 10 three-quarter-miles to unbroken blocks. The one small limit is that all the hard work sits at the same pace, with no faster intervals, so the strides are your only running above goal pace. Treat them as real speed work: quick and relaxed, with a full walk or easy jog between each one so every stride is as smooth as the first.
Workouts
Every Buena Vida training plan comes with detailed coaching notes and live workout guidance. Tap any workout to preview the notes for that day.
Running most days of the week is the whole ask for now, and every run is easy. Hold a pace where you can speak in full sentences, even if it feels slower than your usual easy. Most runners chasing a time goal want to prove something early. Save that urge for later. These opening days teach the legs the rhythm of the plan before anything faster arrives. The runner who stays patient here tends to meet the hard days fresher.
M 3mi Easy Run
3 miles at a pace where you could hold a full conversation. This is where the plan starts. Today's job isn't fitness. It's showing up. The body has to learn the rhythm before anything faster is asked of it.
Tu 3mi Easy Run
Same conversational effort as Monday. If your watch is pulling you faster than feels comfortable, cover it for the first 10 minutes and run by breath instead.
W 3mi Easy Run
The third easy day in a row by design. Easy means easy: you should finish wanting to do more rather than less. Most runners run their easy days too hard at the start and feel it once the harder days arrive.
Th 3mi Easy Run
Fourth run of the week at the same conversational effort. The legs are still adjusting to consecutive days at this distance. Hold the same effort you started with and let the rhythm settle in.
F Strength Training
Sa 5mi Easy Run
5 miles easy, at a pace where you can talk in full sentences. The weekend runs in this plan are about distance at a conversational effort, and hitting a pace is for Tuesday and Thursday. Some runners haven't run 5 continuous miles in a while. If today feels long, that's normal, and the legs get used to it quickly.
Su Rest
The runs stretch a little, and the effort stays exactly where it was. Nothing here should feel hard. The job is to finish each run with the same comfort as before, just with a little more running in it. Most runners notice the legs feel a bit heavier by the weekend, which is the body getting used to back-to-back days. That heaviness is normal. It fades as the rhythm becomes familiar, usually sooner than expected.
M 3.5mi Easy Run
3.5 miles easy, slightly longer than before at the same effort. The mileage steps up by tenths because the body absorbs distance better in small adds than in jumps. Keep the effort at a pace where full sentences come without strain.
Tu 3.5mi Easy Run
Same effort as Monday. If the legs feel heavier than they did on Monday, that's back-to-back easy days stacking. Expected. Miles like these are where your aerobic base builds, one easy run at a time.
W 3.5mi Easy Run
Two more weeks of unbroken easy work before speed work joins. Use this week to settle into the cadence of running 5 days a week, if it's new to you.
Th 3.5mi Easy Run
3.5 miles easy before the harder days begin. Notice how this run feels at this effort: it's the baseline you'll measure interval and tempo days against later.
F Strength Training
Sa 6mi Easy Run
6 miles easy, a small step up from last weekend. Same effort, slightly more time. If last weekend's run left you tired, today should feel similar. If it left you fresh, today should still feel just slightly long.

Plan Strengths
- One pace taught two ways: in repeats on Tuesday and unbroken on Thursday, fusing into a 6-mile continuous block late in the build.
- Easy days stay truly easy, about 80% of the running, and no two hard days ever fall back to back.
- The lighter weeks drop the hard sessions and the mileage with them (week 8 falls to 20 miles from 33), so tiredness gets room to clear.
- A 14-mile dress rehearsal with 3 miles at goal pace in the middle, three weeks out from race week.
- A taper that cuts the running but keeps a short goal-pace run in every week, right up to race week.
Weaknesses & Gaps
- The first week back from the first lighter week is the sharpest jump in the plan: an extra interval rep, a longer tempo and the first 8-mile long run all arrive together.
- The first interval session and the first tempo arrive in the same week, which also adds mileage.
- Every hard session runs at goal pace, so there's no faster interval work beyond the strides.
What's missing
Nothing in the schedule takes you up a hill. If your race course rolls, take some easy runs and a couple of the long runs onto rolling ground at the same talking effort, so the climbs on race day aren't the first ones your legs have met in months. It also schedules no tune-up race. If you like racing, a 5K or 10K can stand in for one Thursday tempo as pacing practice. Run it controlled, a notch short of flat out, and keep it away from weeks 4, 8 and 12 and the taper.
What the science supports
Shifting training emphasis beats unchanging training
Planned shifts in emphasis from base to build to taper tend to beat holding one kind of training all the way through, though the edge is small. This plan has four phases. Weeks 1 and 2 are all easy, and goal-pace work enters in week 3. Weeks 5 to 13 build in cycles split by cutback weeks, ending with a 14-mile long run. Weeks 14 and 15 trim the miles while keeping short goal-pace runs, and week 16 is race week.

Explosive work can make you more efficient
Strides are short, relaxed bursts of fast running, about 100 meters each. Short explosive efforts like these can make your running more economical, so a pace costs less energy, though results are mixed and strides themselves have not been tested directly. This plan closes an easy Monday or Tuesday run with 4 strides in every week from week 3 through week 15. They cost a few minutes.

Easy miles do most of the work
Easy running is most of a runner's weekly mileage, and this plan keeps about 80 percent of its running at an easy, conversational effort. Mondays, Wednesdays and most Saturdays stay easy, while Tuesday and Thursday carry the goal-pace work through the build. That wide easy base carries the harder days and lets your body keep up with them.
A real taper sharpens you for race day
Tapering for up to 3 weeks before a goal race beats holding training steady, as long as some faster running stays in. Here the taper runs 2 weeks after the 39.6-mile week 13. Weekly running drops to 29.5 miles, then 24, and the long run falls from 14 miles to 11, then 10. A Wednesday run still holds goal pace for 3 miles, then 2, so the legs recover without losing the feel of race speed.
Strength training makes running more efficient
Strength work usually makes trained runners 2 to 8 percent more efficient, so the same pace costs less energy. Coaches call this running economy. VO2 max, the most oxygen the body can use, barely moves, so the gain is in efficiency alone. This plan gives strength its own day, every Friday from week 1 through week 15, between Thursday's tempo and Saturday's long run. Friday holds no run, so the week stays at 5 runs plus 1 strength session.
