Plan at a Glance
You don't need to run 13.1 miles before race day to finish 13.1 miles on it. That idea mostly comes from the marathon world's 20-miler, and from the friend who did the full distance before race day and swears by it. The longest run here is 10 miles. For a first half, a long run that keeps you moving for an hour and a half to two hours does the job.
What gets you there is three runs a week, each with one job. Monday and Wednesday are easy, at the pace where you can talk in full sentences, and some Mondays finish with a few strides (short, quick, relaxed accelerations). Saturday is the long run. It starts at 4 easy miles and climbs mostly a mile at a time. After the first few climbs it steps back once so your legs can catch up, then takes one bigger jump and builds to 10 in the biggest week. Tuesday is a strength session. Thursday and Friday stay empty, so the long run starts on fresh legs.
Once the long run has grown, the harder running arrives in small doses: one hill session, one fartlek (faster surges dropped into an easy run), and 3 miles at half-marathon effort inside the 10-miler. That block is the closest you'll come to the race before race day, and the job is to hold it level rather than push it. Short phrases come out, full sentences don't.
Here are two numbers to hold onto. Your biggest week of training is 17.5 miles. The race asks for 13.1 of them in one morning, and the last 3 are ground you haven't covered yet. That is how first halves are meant to go. The miles fall away in the last stretch so you meet those 3 with legs that have had time to absorb everything before them.
Start here if you already run about 10 miles a week across three runs, something like 3, 3 and 4 miles. If three runs is all your week can hold, that is the week this plan was drawn on, not a bigger plan with two days cut out.
The review below is Buena Vida's full assessment of the plan. We grade every plan against the same detailed, 30-point benchmark. Each measure draws from peer-reviewed sports-science research and proven coaching best practices.

Our Review
If you've wondered whether three days a week is enough for a half marathon, for a first one it is. What a first half asks for is a long run that has grown, on legs that aren't worn down by everything else, and this plan builds its whole week around that. The long run is the only thing that really has to grow here. It climbs from 4 miles to 10 over the build, steps back once partway up, and eases off after the peak. Nearly everything else is easy running. The long-run build, the share of easy miles, the recovery weeks and how well the volume fits the distance are the plan's real strengths, and they are what get a first-timer to the finish.
It runs thinner in three places. Its two workouts (hill repeats in week 5, a fartlek in week 6) land in the weeks where the load climbs fastest. Race week is cut very deep. And with only two workouts, there's little here to sharpen a finish time. None of these is a reason to pass on it. If your goal is to finish your first half feeling strong, and your week has room for three runs, run this plan.

Structure
Does the plan build you up smartly?
Step by step, with every phase earning its place. Base, build, taper and race week each hold their own part of the 10 weeks, so you can tell what a 4-mile Saturday and a 10-mile one are each for. Your weekly running builds to its peak in week 7 and comes down again on the way into the race.

Prevention
Does the plan protect you from injury?
The guardrails sit where a new half marathoner needs them. Close to nine in every ten miles are easy, both workouts open with a warm-up and close with a cool-down, and no hard run is followed by another the next day. The step back in week 4 is doing real work. The week drops from 12.5 miles to 9.5 and the long run from 6 to 5, which clears the tiredness of the first three weeks before the bigger ones arrive. The thing to watch is timing. The hill session lands on a Wednesday in week 5, the day after strength, in the same week the volume climbs back out of the cutback and the long run jumps from 5 miles to 8. Week 6 then stacks the fartlek and a 9-miler on top of that jump, which makes it the heaviest week of the plan relative to the three before it. Your breathing may find the week 6 9-miler easy while your tendons and bones are still catching up to week 5, since those tissues take longer to adapt. Those two weeks are where a first-timer is most likely to pick up a niggle.

Flexibility
What happens when you miss a day?
With three runs a week, each has a clear rank, and that makes the choices simple. The Saturday long run comes first, the Monday and Wednesday runs next, and the Tuesday strength session after that. If you lose a weekday run, let it go rather than squeezing it into Thursday or Friday, which are there to rest your legs before the long run. If Saturday falls through, Sunday is open, and the long run is the one worth moving. If a whole week goes sideways, repeat the last long run you finished instead of jumping to the next one. Because the plan keeps its harder days well apart, shifting one run a day or two rarely crowds anything else.

Readiness
Will the plan deliver race-day fitness?
The fitness a first finish needs is all built in. Weekly running peaks at 17.5 miles in week 7, and the long run reaches 10 miles three weeks before the race. Those 10 miles hold 3 at half-marathon effort, the plan's one full rehearsal of race day, and the effort to aim for is the one where short phrases come out but full sentences don't. For a half, a long run of an hour and a half to two hours is what the distance asks for, so stopping at 10 is a choice, not a gap. The soft spot is the taper. Week 9 eases off well. Race week keeps a faster touch (Friday's shake-out ends with strides), but there's very little running around it: after the last long run, five days pass without a run, then 15 minutes on Friday and the race on Sunday. A good taper trims the running rather than removing it. That many empty days can leave legs feeling flat on the morning they need to feel lively.

Variety
Are the workouts varied enough?
Wide in the kinds of running, the breadth that matters this early. The plan mixes easy runs, long runs, strides, a hill session, a fartlek, the race-effort block inside the 10-miler and a shake-out, which is a good range of run types. What it holds back on is the number of hard sessions: two in the whole plan, in two formats. That is a fair trade for a first half, where easy miles and the long run do most of the work. It gives you less to build on if you came to finish and have started to wonder what time you might run. The harder efforts are also described mostly by feel (threshold, tempo, recovery) rather than set to a pace, with only the half-marathon block tied to your half-marathon pace. For a first-timer, learning effort by feel is a useful skill to bring to race day.

Something is different now that the training has actually started. You have moved from thinking about a half marathon to training for one, and that shift is bigger than it might feel today. This week is meant to feel ordinary on purpose, because the real work right now is teaching your week to hold running in it. Some doubt about whether you really belong here is normal, and it is not worth listening to. You signed up, and you showed up. That is the whole job this week.
M 3mi Easy Run
3 miles easy. This is the opening run of the plan. Hold a pace where you can talk in full sentences. If it feels slow, that is the point. Easy days are easy here so you've got a full tank for the long run.
Tu Strength Training
W 3mi Easy Run
3 miles easy at a conversational pace, same as Monday. Easy runs stacked week after week are the foundation. Miles like these are where your base builds, one easy run at a time.
Th Rest
F Rest
Sa 4mi Easy Run
4 miles easy, a little longer than the weekday runs. Pace stays conversational the whole way. The point is to teach the legs what a longer easy effort feels like. Finishing comfortably is enough.
Su Rest
If running already feels a little easier in places than it did a week ago, that is real. If it does not feel any different yet, that is also normal. Your body is taking in the new rhythm before it shows up as anything you can name. Keep the easy days truly easy. Many beginners try to outwork their training about now. The better move is to stay patient with how slowly real changes show up.
M 3mi Easy Run
Easy 3 miles at conversational effort. It should feel like the body is warming up. Trust the pace. The work this week is showing up 3 times. The job today is gentle repetition, the kind of running that adds up without ever feeling like work.
Tu Strength Training
W 3mi Easy Run
Easy 3 miles, conversational. The mid-week run is where the base keeps growing. It should feel less like training and more like routine. Easy days exist to let the harder days do their work, and they only work if they stay easy.
Th Rest
F Rest
Sa 5mi Easy Run
Long run, 5 miles easy. Conversational the whole way. If the pace creeps faster after mile two, pull it back. Long runs reward patience. This run keeps the rhythm of training alive without over-taxing your legs.

Plan Strengths
- A long run that grows mostly a mile at a time from 4 miles to 10, with one step back before the peak so your legs can catch up.
- Outside the hill session and the fartlek, Monday and Wednesday stay at a talking pace, which leaves Saturday as the one run that has to grow.
- One clear race rehearsal: 3 miles at half-marathon effort inside the 10-miler.
- You get a breather partway up and again after the peak, before the load can pile up.
- Both workouts open with a warm-up and close with a cool-down, and no hard day follows another.
Weaknesses & Gaps
- The hill session (week 5) lands in the same week the volume climbs back out of the cutback and the long run jumps to 8 miles.
- Week 6 stacks the fartlek and a 9-mile long run on top of that jump, the heaviest week relative to the three before it.
- Only two true workouts in the whole plan, in two formats, so there is little here to build a time goal on.
- Race week is cut very deep: a 15-minute shake-out is the only run between the last long run and the race.
What's missing
You can supply the 3 missing pieces yourself. First, a run early in race week: after the last long run, nothing happens for five days until Friday's 15-minute shake-out, so add an easy 20 to 30 minutes on Tuesday or Wednesday to keep some running in the week. Second, a softer landing for the two workouts: the hill session in week 5 and the fartlek in week 6 arrive in the two weeks where the load climbs fastest, so run the hills by feel, drop a rep or two if your legs are heavy from Tuesday's strength, keep those weeks' long runs easy with short walk breaks if you need them, and if a nagging ache shows up, ease off until it settles rather than running through it. Third, more hard running if you want it: two workouts is enough to finish a first half well, but if a finish time matters to you, a plan built around a time goal will give you more to work with than this one.
What the science supports
Longer long runs go with faster marathons
The long run, the slow weekend run that builds endurance, grows from 4 miles in week 1 to 10 miles in week 7, stepping back to 5 miles in week 4 so the body can catch up. Marathoners who log longer long runs tend to finish faster, though that is an association rather than a tested rule, and it matters less at the half. Many first-timers still notice that the growing long run is what makes 13.1 miles feel possible.

The body adapts on a staggered clock
The first 4 weeks hold no hard sessions, only easy running at a conversational pace, where you can talk in full sentences. Harder work arrives after that: hill repeats in week 5, a fartlek, a run with short faster surges, in week 6, and 3 miles at half-marathon effort inside the week 7 long run. Different parts of the body adapt on different clocks. Blood and muscle energy systems tend to improve within weeks, while bone takes months, so easing in makes sense even when you feel fit early.

Shifting training emphasis beats unchanging training
The plan moves through four distinct phases. It starts with three weeks of base building, steady easy running that lays the groundwork. Then a five-week build lifts the long run to its 10-mile peak in week 7, followed by one taper week, a lighter stretch before race week. Each phase prepares differently. Plans that change their emphasis over time like this tend to beat plans that hold the same mix throughout.
Filipas et al. 2021; Bradbury et al. 2020; Sandbakk et al. 2025
A real taper sharpens you for race day
After the 10-mile peak long run in week 7, the long run steps down to 8 and then 7 miles, and week 9 covers about 12.5 miles against the 17.5-mile peak week. Race week holds only a 15-minute shake-out run before Sunday. You may feel restless, but that is the fatigue washing out. A taper, the planned wind-down before a race, works: cutting running by roughly 40 to 60 percent while keeping a few faster touches improves race performance compared with not tapering.
Strength training lowers injury risk
A strength session sits on every Tuesday from week 1 through week 9, 9 sessions in all, and race week leaves it out. A review of 25 trials found strength training cut injuries to about a third of what groups without it saw, most clearly in team sports and less so in running. Tuesday sits between two running days, so the session never crowds a run. A weekly habit is the point, since the benefit grows with how much lifting you actually do.
