Plan at a Glance
You can already run 13.1 miles. That part is settled. What sub-2 asks is different: holding one pace, your goal pace, for the whole distance, including the miles where your legs would rather slow down. All ten weeks answer to that one demand. It isn't trying to make you able to go farther. It's trying to make goal pace feel like a pace you know.
So once goal pace arrives, it comes back most weeks, in a shape that keeps changing. It starts on Wednesdays as half-mile repeats with easy jogs between. The repeats get longer and more numerous until they add up to more than half the race. Then goal pace spreads to Saturday too, as the closing miles of your long run, when you're already tired, while the Wednesday repeats stay at their longest. In the last stretch it becomes a single steady run, then a short reminder in race week. By the start line you will have visited this pace many times, fresh and tired, in pieces and whole.
Around it, most of the week is easy. You run four days: an easy Monday with a few strides, the Wednesday session, an easy Thursday, and the Saturday long run. Strength sits on Tuesday and Friday. The longest run in the plan is shorter than the race, since you already have the distance and the plan spends its effort on pace. The plan opens with four easy 5-mile runs, so come in already running about 20 miles a week across four days. Then watch your Thursdays. After a good Wednesday, your easy pace will come out quicker than usual at the same effort. That's the fitness arriving. Don't spend it on Thursday; Saturday needs it.
What follows is our full review of the plan. Buena Vida grades every plan on the same detailed, 30-point benchmark. Each measure comes from peer-reviewed sports-science research and proven coaching best practices.

Our Review
If you've finished a half somewhere past two hours, and your calendar has room for four runs a week rather than six, this is a strong plan to take that number down. Here is how it thinks. You never run the race distance before race day. The longest run is 12.5 miles. But on the biggest Wednesdays you run more than half the race at goal pace in one morning, in three-quarter-mile pieces. The distance is trusted to the base you already have. The pace is what gets rehearsed, again and again, until it stops feeling like a guess. Most of the rest of the week is easy, and three lighter weeks give your legs a regular break from the load.
The gaps are few and specific. Week 3 brings the plan's sharpest jump in load, and week 5 puts a new hill session the day after a long interval session. Neither is a reason to pass on the plan. They're the two weeks to run with a little restraint, trimming a rep or easing the hills if your legs are telling you something. Do that and keep Thursdays easy, and the rehearsals are built to make goal pace feel familiar by race week.

Structure
Does the plan build you up smartly?
Step by step, in a clear order. The plan moves through five distinct phases: easy base, a build where goal pace arrives, a peak where it reaches its longest and joins the long run, a taper, and race week. Weekly running climbs from 20 miles to a peak of 34.5 in the peak phase. Changing the emphasis in phases like this tends to beat training the same way all the way through.

Prevention
Does the plan protect you from injury?
Mostly, with two weeks to handle carefully. Apart from Wednesday's reps and the goal-pace finishes on a few Saturdays, nearly all of it is running at the pace you can talk at. Every Wednesday session, the hill repeats and the pace runs open with a warm-up and close with a cool-down, strides sit on the calendar, and strength is scheduled twice a week. Lighter weeks in weeks 4, 8 and 9 keep the work from piling up without a break. You'll feel the rhythm of it: a few weeks that ask more, then a week that hands some back. The weak spot is week 3. The first goal-pace intervals, the first strides, a longer Saturday and the biggest week so far all land together, and sharp jumps in load like that are a known injury risk. Week 5 has a smaller version: hills appear for the first time, in a big week, the day after 8 × 0.75 mile, so two hard days sit back to back. Many running injuries start suddenly rather than creeping in slowly, often right after a single run well past your recent longest, and week 5's 12.5-mile long run is one. If something aches in week 3 or 5, cut a rep or two rather than pushing through.

Flexibility
What happens when you miss a day?
The plan tells you what to protect by how it weights each day. The Wednesday session and the Saturday long run always carry the most weight. So does the Thursday easy run after the biggest interval days, in weeks 3, 6 and 7, because that's the run that keeps Saturday possible. Monday's easy run is the first to let go, and Thursdays in the other weeks are next. If you miss a Wednesday, run it on Thursday in place of the easy run, and if that week's Saturday closes at goal pace, run the whole long run easy instead. If you miss a Saturday, run it Sunday at the pace you can talk at and skip any goal-pace finish. Should a whole week slip away, leave it behind and rejoin the calendar at the following Monday rather than making it up. A sub-2 build survives a missed session far better than it survives two hard days stacked to catch up.

Readiness
Will the plan deliver race-day fitness?
Goal pace sits at the heart of this build, and the work around it is well chosen. A peak week of 34.5 miles and a longest run of 12.5 sit well within what a half marathon asks, and goal pace is trained in some form most weeks from the first interval session on. The long runs in the peak weeks close at goal pace on tired legs, the nearest thing to rehearsing the back half of the race. Treat them as pacing practice rather than a fitness boost: what they teach is how goal pace feels when your legs would rather slow down. Two small notes. The 12.5-mile run comes in week 5 and isn't repeated, so your longest effort is five weeks out. And race week cuts very steeply, which can leave you feeling flat or restless. Protect the Monday goal-pace run, because it's the touch that keeps the rhythm in your legs.

Variety
Are the workouts varied enough?
One pace, worked in many shapes, gives this plan real range. If you've been running most days at the same medium effort, a bit quicker than easy and a bit slower than hard, because that's the run that feels like work, this plan will feel strange at first. It keeps its fast running to two days and lets the rest go genuinely easy, so the hard days can be hard. Within those two days, goal pace never sits still: short repeats, longer repeats, a goal-pace finish to the long run, and a single continuous block. Strides through the middle weeks and the one hill session add a touch of work above goal pace. Each session has a clear reason to exist, and the shape changes before any of them goes stale.
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.
There is a particular feeling to starting a plan, and most of it has nothing to do with the running itself. You have decided to point your training at a specific outcome over the next 9 weeks. That choice is doing some work in the background of every easy day this week. Take it lightly. There is nothing to prove yet, and a lot to settle into.
M 5mi Easy Run
5 miles at a pace where talking would still work. Keep the pace light on purpose, even if the legs feel ready for more. The first run of a new plan often feels heavier in the head than in the legs, like the body is checking whether you mean it this time.
Tu Strength Training
W 5mi Easy Run
Five easy miles, second run of the week. 2 run days in, your body will start telling you which leg is tighter. That's normal early in a build. Don't fix it on the run. Fix it after.
Th 5mi Easy Run
Five easy miles, conversational. 3 runs in, you may feel the load a little. That's the body adjusting to load rather than pushing back. Slow when it asks. Conversational pace is the ceiling here.
F Strength Training
Sa 5mi Easy Run
5 miles easy, on the Saturday slot where the long run will live. 5 miles is short for a long run, but the day on the calendar matters more than the distance this week. This is the run that grows on most Saturdays from here. Run it slower than the weekday runs. Most runners spend a Saturday run like this waiting for it to feel hard. Let it not.
Su Rest
What is happening underneath these easy days is not always visible from the outside. Your aerobic system is starting to remodel, and your tendons are learning to absorb a little more. The rhythm of running on the same days each week is starting to feel familiar. Most of the meaningful work in a half-marathon block happens at the unflashy intensities, and this is one of those weeks. Stay patient with how slow the easy effort is supposed to feel.
M 5.5mi Easy Run
5.5 miles easy. A small step up from the runs before it, same effort. You may feel a touch of fatigue from the recent strength sessions. That's fine. Hold conversational pace and let the legs warm up gradually.
Tu Strength Training
W 5.5mi Easy Run
5.5 easy miles, mid-week. By now the days of the week should be settling into a pattern. If you feel sluggish, slow down. The goal of a midweek easy is to show up rather than chase a pace.
Th 5.5mi Easy Run
5.5 easy miles. Same effort, third run of the week. This is the run where the body starts feeling like it knows what it's doing on Thursdays. Trust the easy pace.
F Strength Training
Sa 6.5mi Easy Run
6.5 miles easy. A 1.5-mile bump from the Saturday before. Treat the extra distance as a continuation rather than a test. You should finish feeling like you could run another mile, even if you'd rather not.

Plan Strengths
- Goal pace is trained in some form most weeks once it arrives, so race pace becomes familiar rather than a guess.
- Monday and Thursday are easy runs in almost every week, so you'll reach Wednesday and Saturday with something left on a four-day week.
- Clear phases and three lighter weeks (4, 8 and 9) give the build a shape you can see, with a breather before the work piles up.
- Every hard session, from the first 7 × 0.5 mile to the race-week pace run, is written out with 1 to 1.5 easy miles on either side and a line on why it's there.
- The long runs in the peak weeks finish at goal pace on tired legs, a direct rehearsal of the closing miles of the race.
Weaknesses & Gaps
- Week 3 brings intervals, strides, a longer Saturday and the biggest week so far all at once, which makes it the plan's sharpest jump in load.
- Hills appear for the first time in week 5, in a big week and the day after 8 × 0.75 mile, so two hard days sit back to back.
- The longest run, 12.5 miles, comes in week 5 and isn't repeated before the race.
- Race week cuts running very steeply, which can leave the legs feeling flat on race morning.
What's missing
Your first step into goal pace comes at full size, with nothing gentler before it. If week 3 is your first time near 27 miles in a while, run 5 or 6 reps on that first Wednesday instead of 7 and keep the Saturday run at the pace you can talk at. The full session will be there the next time it comes around. It also leaves no easy day between the week 5 intervals and the new hill session, so if Wednesday took a lot out of you, run the hills at a gentler effort or with fewer reps, or swap them for an easy run. The long run doesn't return to its longest distance before the race, and that's fine to leave alone. The goal-pace long runs that follow carry the race-specific work, so don't add a second 12.5 on your own. And race week offers little middle ground between the last real long run and the race itself, so expect to feel restless, keep the Monday goal-pace run and the shake-out strides, and let the flat feeling pass.
What the science supports
Two strength sessions a week is enough
Tuesday and Friday hold strength every week through week 9, two sessions on days with no running, and race week leaves them out. Two sessions a week is the amount that does the job for most runners. Kept up for a couple of months, that dose makes a given pace feel easier, and in pooled trials more sessions added nothing further.

Fast-finish long runs are tradition, not proof
In weeks 6 and 7, the Saturday long run closes with 2, then 3 miles at goal pace on tired legs. Those finishes come on top of the week's Wednesday intervals, not in place of them. Finishing a long run faster is a coaching tradition rather than a proven edge over a steady long run. Treat these finishes as pacing practice and keep the easy miles before them truly easy.
Shifting training emphasis beats unchanging training
Your plan has five named phases moving from base through build, peak, and taper toward race day. Week 4 cuts volume by roughly a third, then week 8 opens the taper with a smaller cut, so the hardest training isn't sustained back-to-back. This structure lets each phase deliver what it's supposed to without overheating the build. Shifting the emphasis like this as race day nears tends to beat running the same effort every week.
Filipas et al. 2021; Bradbury et al. 2020; Sandbakk et al. 2025
Easy miles do most of the work
Across the plan, 84 percent of your running is easy. The first two weeks are nothing but conversational running, 20 miles and then 23. Even in peak week 7, at 34.5 miles, about 25 of them are easy: the Monday and Thursday runs, the warm-ups and jogs around Wednesday's intervals, and the first 7.5 miles of Saturday's long run. That easy foundation is what carries the goal-pace work and helps your body adapt to it.
A real taper sharpens you for race day
Volume comes down from the 34.5-mile peak in week 7 to 27 miles in week 8 and 21.5 in week 9. Race week holds just 7.5 miles before the race: a 3.5-mile run with 1.5 at goal pace on Monday, a 2-mile easy run on Wednesday and a 2-mile shake-out on Friday. Goal pace stays in every taper week. Trimming the miles while keeping some speed is how a taper earns its edge, and runners race better for it than when they hold training steady.
