Plan at a Glance
A sub-2 half marathon is one pace held for 13.1 miles. It starts out feeling controlled, and somewhere past mile 10 it stops feeling that way. This plan is built to teach you that one pace until it feels like yours. On Wednesdays you meet goal pace in short repeats, half a mile at a time, then in longer ones, until a single session holds more than 6 miles of it. In those same big weeks, goal pace also closes the Saturday long run, so you practice holding it on legs that have already run 7.5 or 9.5 miles. In the last stretch the mileage comes down and goal pace stays, in smaller doses, right up to race week.
Most of the rest is easy, and that's the part runners tend to rush. You run Monday through Thursday and Saturday, lift on Friday, and rest on Sunday. Five running days let each run stay shorter and gentler than it would on four. A few quick strides on Tuesdays and one session of short hill climbs keep your legs sharp. The other runs sit at a pace you can talk at, and that easy running is what lets Wednesday be hard. If easy has always felt like wasted time to you, this plan asks you to trust it anyway. Everything before the first goal-pace week is easy running. The longest run, 12.5 miles, comes five weeks before race day, and every long run after it is shorter while the goal pace inside them grows. The endurance goes in early, and the late weeks are about pace.
This plan is for a runner who has finished a half before, wants to get under two hours, and already runs about 20 miles a week. Two weeks ask the most of you. The first is the week goal pace arrives. The second follows the first lighter week, when hill repeats, longer intervals and that 12.5-mile run all land together. You'll come out of the light week feeling springy, and Tuesday's hills will invite you to attack them. Run them controlled. Wednesday's intervals and Saturday's long run are what that Tuesday is really for.
Below is Buena Vida's full review. We score every plan against the same detailed, 30-point benchmark, with each measure rooted in peer-reviewed sports-science research and proven coaching best practices.

Our Review
Focus is what makes this a strong sub-2 half plan. Nearly every hard minute is spent at goal pace, and that work grows in an order that makes sense: half-mile repeats in week 3, three-quarter-mile repeats in week 5, 9 of them in weeks 6 and 7, goal-pace finishes on the long runs those same weeks, then smaller doses through the taper so the rhythm is fresh on race day. Around it, four of five running days stay easy, a cutback week follows the first workout week, a three-week step-down follows the peak, and each Wednesday session is framed by 1.5 easy miles at either end.
You may wonder whether that's enough. The longest run is 12.5 miles, five weeks out, and you never hold goal pace for more than 3 miles at a stretch. The plan is betting that the pieces add up: more than 6 miles of goal pace in a single Wednesday session, 3 of them at the end of a long run, and 10.5-mile long runs that keep your endurance topped up. Peak mileage and the longest run both fit the distance. What costs the plan is when that longest run comes, not how long it is.
The bigger gap is how fast the load rises in week 3, the biggest jump in total training stress in the plan: mileage climbs, and strides and the first goal-pace intervals arrive in the same week. The day that decides it is Thursday, the easy run after those first intervals. Run it slow enough that it feels almost too easy, and Saturday has room to go well. Week 5 brings the biggest rise in miles, straight out of the cutback, with hill repeats on Tuesday the day before the longest intervals yet. If you change one thing, move those hills to Monday. Race week is also very light. Run this plan. It's built for exactly the race you're chasing.

Structure
Does the plan build you up smartly?
Patiently, with a cutback after the first workout week that drops volume by about a third. The plan moves through five clear phases (base, build, peak, taper, race week), and each one changes the job. The opening weeks are easy running only, so five days a week becomes routine before any hard work arrives. The peak puts the biggest Wednesday sessions and the goal-pace long runs together, and a three-week step-down then brings the mileage off while goal pace stays. Changing the emphasis as the race nears tends to beat training one way throughout, and here the phases are easy to see.

Prevention
Does the plan protect you from injury?
Day to day, yes. Four of five running days are easy, and nearly every note says so. Clearly separating easy days from hard ones keeps the hard days worth doing, and for trained runners the evidence leans that way. All 7 hard sessions open with a warm-up and close with a cooldown, and strides, a hill session and Friday strength until race week give your legs more to work with. Where the plan protects you less is in how fast the load rises in two weeks. Week 3 carries the biggest jump in total training stress: more miles, plus the first strides and the first goal-pace intervals. Week 5 carries the biggest rise in miles, coming off the cutback, with the long run going from 6.5 to 12.5 miles and hills on Tuesday the day before intervals. Sharp jumps in load raise injury risk. Injuries that seem to come from nowhere often follow a single run well past your recent longest, and week 5's long run is one. Out of the 21-mile cutback week, heart and lungs will be ready for that 12.5-mile Saturday before tendons and bone have caught up, which is why fresh legs can fool you. If a niggle shows up in either week, the usual move is to run clearly less for about a week, not to push through and not to stop entirely.

Flexibility
What happens when you miss a day?
The plan marks what matters most. Wednesday's workout, the easy Thursday after it and the Saturday long run are the sessions to protect. When a week gets crowded, Monday's and Tuesday's easy runs give way first. If you miss a Wednesday, don't cram it into Thursday and then head straight into a long run. Either skip it, or run it Thursday and keep Saturday easy all the way through, dropping the goal-pace finish that week. The workouts carry their own scaling advice: slow the reps rather than cut the cooldown, ease the pace before you ease the distance, cut the race-week pace run short if your legs feel heavy. Lose a few days to illness and the missed runs stay missed. Carry on from whatever day it is. And a short run still counts. The Monday right after the cutback is only 3 miles, and it's doing real work.

Readiness
Will the plan deliver race-day fitness?
Confidently, and the pace work leads the way. Peak mileage and the longest run both fit what a sub-2 half asks for, and the race-specific work is the best thing in the plan. By the end of the peak you've run 9 three-quarter-mile reps at goal pace twice and finished a long run with 3 miles at goal pace on tired legs, which, as the plan puts it, is what the last 5K of the half feels like. The taper keeps goal pace in smaller doses while the miles fall, so the rhythm is still in your legs on Sunday, and a structured taper like this improves race-day performance compared with training straight through. Two cautions. The longest run comes five weeks out, so the later long runs keep your endurance topped up rather than stretching it. And race week is very short, which can leave you feeling flat by midweek.
-
Variety
Are the workouts varied enough?
The weeks rarely repeat themselves. You get easy runs, long runs, strides on most Tuesdays from the first workout week, one hill session, four interval sessions in three formats (7 × half-mile, 8 × three-quarter-mile, then 9 × three-quarter-mile twice), standalone goal-pace runs in the taper, long runs with goal-pace finishes, and one long run with a goal-pace block in the middle. The variety lives in the shape of each session more than in its pace. Almost all the hard running is at goal pace, which keeps the plan fixed on the one speed you'll race at, while the strides and the hills give your legs something quicker. Short fast efforts like strides keep quick running in your legs, and they cost very little. Tuesday is still the first easy run to drop in a hard week, but if Tuesday stays, the strides are the part worth keeping.

You set a goal time for the half marathon and decided to spend 10 weeks earning it. That choice is the whole foundation everything else gets built on, and you have already made it. The runs this week are mostly about settling in, finding the rhythm of running on most days, and letting your body learn what regular training feels like. Nothing here is meant to push you yet. The hard weeks are coming, and the steady foundation you are starting on now is what carries you into them when they arrive.
M 4mi Easy Run
4 miles easy, conversational. The first run of a plan often feels different in the head than in the legs. The legs need time to get used to the new routine. Keep pace light on purpose. If you could hold a conversation, you've got it.
Tu 4mi Easy Run
Same effort, second day in a row. Frequency is the point of a 5-day plan, built by treating the second day exactly like the first. Keep the effort at a pace where full sentences come without strain.
W 4mi Easy Run
By the third consecutive run-day the legs may carry a small cumulative shift in the first half-mile. It isn't overreach. The body is settling into daily running.
Th 4mi Easy Run
4 days, 4 runs. If pace creeps faster today because the routine feels good, gently rein it in. Easy early is what makes hard work possible later.
F Strength Training
Sa 5mi Easy Run
5-mile long run, easy effort. Same pace as the weekday runs. The only thing that changes is duration. A long run asks the legs to learn patience, and the closing mile is where that lesson lives. Don't push it. Let the rhythm of running for most of an hour settle in on its own.
Su Rest
The runs may still look ordinary from the outside, but the training is starting to add up in ways you cannot quite see yet. Your tendons and ligaments are getting used to the work. Your breathing settles sooner, and the legs are learning to run on a regular schedule. By the back half of the week you might notice a heaviness that was not there before. That is not a sign you are doing too much. It is a sign the training is working its way in.
M 4.5mi Easy Run
4.5 miles easy. The extra half mile on each weekday run is small enough that you may not notice it until the cool-down. Most runners feel the week more in its rhythm than in any single run. Let these add up without asking much of any single day.
Tu 4.5mi Easy Run
Same effort as yesterday. 2 days at the new distance. The legs should feel steady about it. Repeating yesterday's run is the whole job, and it counts even when it feels like nothing.
W 4.5mi Easy Run
Third weekday at the slightly higher mileage. The week adds up a little faster than the one before, because frequency works that way. Keep it at talking pace so the weekend long run starts on fresh legs.
Th 4.5mi Easy Run
Last weekday before the long run. Keep this run easy. Saturday should feel like it has somewhere to go. Holding back today keeps the weekly rhythm going without taking anything from Saturday.
F Strength Training
Sa 6.5mi Easy Run
6.5-mile long run, easy throughout. The temptation on long-run day is to push the last mile because the body knows the run is ending. Resist it. Long runs build the aerobic engine. Finishing speed comes from elsewhere.

Plan Strengths
- Goal pace builds in a clear order: 7 × half-mile repeats in week 3, 8 × three-quarter-mile in week 5, 9 × three-quarter-mile in weeks 6 and 7, then goal-pace finishes on the long runs.
- Easy days stay easy. Four of five running days are conversational, which keeps Wednesday's session worth doing.
- A cutback week after the first workout week, and a three-week step-down from the peak that keeps goal pace in small doses all the way to race week.
- All 7 hard sessions are written out in full, from the 6 × 60-second hill climbs to the 9 × three-quarter-mile reps, each with a note explaining its job.
- Strides, a hill session and Friday strength until race week are all on the calendar.
- Peak mileage of 39.5 and a longest run of 12.5 fit the half marathon.
Weaknesses & Gaps
- Week 3 is the biggest jump in total training stress: mileage climbs while strides and goal-pace intervals both arrive for the first time.
- Week 5, straight out of the cutback, is the biggest rise in miles, with the first hill repeats, longer intervals and a long run that goes from 6.5 to 12.5 miles. Week 6 climbs again on top of it.
- Tuesday hills sit the day before Wednesday intervals in week 5, the plan's one pair of back-to-back hard days.
- The longest run comes five weeks before the race, and every long run after it is shorter.
- Race week is very light, under 10 miles of running before the race.
What's missing
Not much that matters for this race. The plan doesn't pull apart its one pair of back-to-back hard days, so do it yourself: in week 5, move the hill repeats to Monday, after the Sunday rest, and run Tuesday's 3 miles easy before Wednesday's intervals. A tune-up race would add little here, since the long run that closes with 3 miles at goal pace already rehearses the last 5K of the half. Race week leaves Thursday and Saturday empty. If your legs feel dull by Thursday, an easy 15 to 20 minutes keeps them awake without costing you anything on Sunday.
What the science supports
Shifting training emphasis beats unchanging training
This plan divides ten weeks into five phases: two base weeks for aerobic building, three build weeks where Wednesday intervals arrive and long runs extend, two peak weeks at high volume plus race-pace work, two taper weeks with volume cuts, and race week itself. Each phase prepares you for the next. The progression from aerobic foundation through build through peak through recovery lets each phase land with purpose. Planned changes in emphasis like these tend to beat training the same way all ten weeks.

Keep easy days easy, hard days hard
Most of your running stays conversational, a pace where full sentences come without strain. Wednesday is the one that bites: goal-pace intervals start in week 3 at 7 by half a mile and build to 9 by three-quarters of a mile in weeks 6 and 7. In every interval week, Monday and Thursday stay genuinely easy around it. For trained runners, separating easy and hard days this clearly tends to work better than running everything at a medium effort, never truly easy and never truly hard.
Stöggl & Sperlich 2014; Casado et al. 2022; Kenneally et al. 2018
Easy miles do most of the work
This plan peaks at 39.5 miles a week, and 86 percent of all its running is at easy conversational pace. The easy days aren't decoration. They're foundational. Wednesday's intervals sit atop a full week of aerobic running, not replacing it. Long runs stay mostly easy too. High easy volume carries the harder sessions and gives them a base to build on.
Threshold or race pace: neither proven better
Starting in week 3, Wednesday brings intervals at goal pace: half-mile repeats growing to 9 repeats of three-quarters of a mile by peak. In weeks 6 and 7, long runs add goal-pace finishes: 2 miles after 9.5 easy, then 3 after 7.5 easy. Week 9 puts 3 goal-pace miles in the middle of a 9-mile run. Race-pace work and threshold running (where easy running turns hard) are different kinds of training. For recreational runners either is a reasonable choice, since no study shows one beats the other.
Smyth & Muniz-Pumares 2020; Jones et al. 2021; Vickers & Vertosick 2016
A real taper sharpens you for race day
Weeks 8 and 9 cut volume by a quarter to nearly a third from the 39.5-mile peak, to 29 and then 27.5 miles. Week 9 includes a dress rehearsal: 3 miles at goal pace in the middle of a 9-mile run. Race week drops to short runs, a 2-mile shake-out on Friday, and the race on Sunday. That kind of structured wind-down, fewer miles with some speed kept, improves race performance compared with holding training steady.
