Plan at a Glance
Most people who sign up for a first half marathon carry one question onto every run: whether they can actually go that far. This plan answers it slowly. You run 3 days a week, and nearly all of it is easy, at the pace where a full sentence comes out without a gasp. Monday and Wednesday are short runs, with a few strides (short, relaxed pickups) on most Mondays. Tuesday holds a strength session. Saturday holds the long run, and that one run is where this plan lives. The long run starts at 4 miles, twice Monday and Wednesday put together.
From there the long run grows mostly in half-mile steps, and every fourth week the whole plan eases off so your legs can absorb what you just asked of them. That patience matters more than it looks. Your heart and lungs adapt in weeks. Tendons and bone take months, and they don't announce when they're behind. A slow climb is how you reach the start line with both the fitness and the legs to use it.
The longest run stops at 10.5 miles, short of race day. A half asks for time on your feet, not a full dress rehearsal of the distance. Your biggest Saturday carries a few miles at half-marathon effort so you know what race effort feels like, and the last stretch backs off so race week is light.
Bring about 6 miles a week and the legs for a 4-mile Saturday, walk breaks included. One habit decides how the rest goes: start every long run slower than feels necessary. Fresh legs after two days off will want to run. Let them wait.
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
Signing up for a first half marathon with 3 days a week to train, and a real worry about the distance, takes some nerve. This plan is an easy one to recommend to that runner. Its best decisions all protect a new runner. Nearly every mile is easy, and the runs that feel almost too easy to count are the ones doing the work. The long run builds in small steps to a 10.5-mile peak three weeks before the race, with 3 miles at half-marathon effort tucked inside as a rehearsal. Lighter weeks arrive on a steady rhythm, and the phases are clear.
The gaps are worth planning around, especially if you carry an old shin or knee story from the last time running got serious too fast. Two weeks ask your legs for more than the build around them: the week after the first cutback, and week 10. The plan is also light on harder running, with one hill session and one fartlek in the middle and little after them. For a first race that's a fair trade, since base comes first, but you'll get little practice at running uncomfortable before race day.
If you run it, make one change. In week 10, run Wednesday at 2 miles instead of 3, and let week 11 take it to 3. That splits the plan's biggest ordinary rise into two smaller steps.

Structure
Does the plan build you up smartly?
The bones of this build are right. Nearly every week stays easy, with one hill session and one fartlek in the middle, and the last 2 weeks before the taper turn toward race effort. Base, build, taper, and race week are each named and explained. Both hard sessions come fully written out, from warm-up to cool-down, with a note on why each is there.
-
Prevention
Does the plan protect you from injury?
Gently, and with a new runner's legs in mind. Nearly all the running is easy, no week holds more than one hard session, and the Wednesday hills open with 1.5 easy miles, the Monday fartlek with 0.5. A weekly strength slot is on the calendar from the first week and strides join early on. Strength work is one of the better-supported ways athletes lower injury risk, so that Tuesday is worth keeping. Every fourth week eases off, a regular break before the next climb. Two climbs still ask more than the weeks around them. Coming out of the first cutback, the Saturday run jumps to 6 miles, well past your longest of the month before. Week 10 then brings the biggest ordinary rise, with Monday, Wednesday, and Saturday all growing at once. Start those long runs truly slow, since a fast first mile is how mile 7 becomes a survival march. If a new ache appears after that 6-mile Saturday and is still there on Monday, run less for a few days rather than push through it.

Flexibility
What happens when you miss a day?
With 3 runs a week, the order is easy to read. Saturday's long run comes first, Monday and Wednesday support it, and the Tuesday strength session sits after those. If you miss a weekday run, let it go rather than tacking the miles onto Saturday. If you miss a Saturday, run it Sunday at the same easy effort, or repeat that distance the following weekend instead of jumping ahead. The workout notes give you standing permission to walk whenever your breathing gets ahead of you and to slow down when the legs are heavy, and the eased-off weeks between climbs give a missed day somewhere soft to land.
-
Readiness
Will the plan deliver race-day fitness?
A first half asks for endurance more than speed, and this build supplies it. The biggest week reaches 18 miles and the long run tops out at 10.5 miles three weeks before the race, which fits the distance. For a half, long runs that keep you out there for roughly 90 minutes to 2 hours do the job, and this build walks you into that range in steady steps. The peak long run carries 3 miles at half-marathon effort, so you'll have felt race effort on partly tired legs before the day. After the peak, weekly volume steps down over three weeks. The gap is at the very end: race week is almost empty, just a 15-minute shake-out with strides on Friday before a Sunday race, and there's no short, sharper session late in the plan to keep some snap in the legs.
-
Variety
Are the workouts varied enough?
Enough to keep a first build interesting. You get easy runs, strides on most Mondays, a long run, one hill session, one ladder fartlek, and race-effort miles inside the peak long run, which is a good spread of run types. What's thin is the hard running itself: just 2 sessions in 2 formats, both in weeks 8 and 9, with nothing between them and race day except the 3-mile rehearsal. Effort is described by feel and effort labels, and the race-effort miles aren't tied to a goal pace. For a runner whose goal is to finish, that costs little.

You decided to do this, and this week is where that decision starts to take shape on the calendar. The opening days do not need anything heroic from you, and they are not supposed to. They are the foundation of everything that comes after, and the months ahead will lean on the groove you set right now. Easy means truly easy, the kind of pace where a full sentence stays comfortable. If anything feels slower than you expected, that is exactly right. Welcome to the start of it.
M 1mi Easy Run
1 mile, easy enough that a full sentence still slips out. This is where the plan begins, and it is meant to be small. Most beginners start out thinking the early miles should feel like effort. They should not. Short, easy runs like this one are what make the 10.5-mile long run later in the plan feel reachable. Run slow now and trust the math.
Tu Strength Training
W 1mi Easy Run
Second easy mile of the week. Same job as Monday: stay at a pace where talking is easy. Nobody falls behind in a plan like this from going too slow. If the legs feel fresh, that is the point.
Th Rest
F Rest
Sa 4mi Easy Run
Saturday's run, 4 miles. Walk breaks are fine if breathing gets ragged. Tired legs afterwards are normal, since this run is longer than the week's other 2 put together. Let Sunday be a true rest day.
Su Rest
With the opening runs behind you, running starts becoming something you do rather than something you are trying. Nothing heroic is required of you here. Just show up on the days that ask for a run, take the rest days seriously when they arrive, and let the rhythm settle in. Weeks like this one are the ones that build the runner who lines up on race day.
M 1.5mi Easy Run
1.5 miles easy. A small step up in distance. The legs may not even register the difference yet. That is correct. Runs this size add up faster than they seem to, one easy day at a time.
Tu Strength Training
W 1.5mi Easy Run
Midweek, 1.5 miles easy. Easy from the first step, at a conversational pace. Conversational means you can speak a full sentence without gasping. If you can only get a few words out, you are running too hard. Pacing by feel takes a few weeks of practice, and the only way to get the practice is to keep it conversational every time.
Th Rest
F Rest
Sa 4.5mi Easy Run
Saturday's run, 4.5 miles. Half a mile longer than last weekend, no other change. If a hill makes the pace feel hard, slow down before it costs you tomorrow. Walking the steepest part is fine.

Plan Strengths
- Nearly every mile is easy, which is the base a first-time half marathoner needs most.
- The long run builds mostly in half-mile steps to a 10.5-mile peak three weeks before race day.
- The peak long run includes 3 miles at half-marathon effort, a real rehearsal of race effort.
- The load backs off after each three-week climb, giving your legs a regular break.
- The two hard sessions land in separate weeks, each with its own warm-up and cool-down.
- Strength sits on the calendar every week, and strides arrive early on.
Weaknesses & Gaps
- The week after the first cutback climbs well past anything before it, the sharpest jump against recent load in the plan.
- Week 10 brings the plan's biggest rise in an ordinary build week, with all 3 runs growing at once.
- Only 2 hard sessions in 2 formats across the whole plan, both in weeks 8 and 9.
- Race week is almost empty, with no faster touch in the final weeks beyond strides.
What's missing
After the hill session and the fartlek, harder running mostly disappears, and nothing faster comes back near the end. For a first half, the first gap matters little. Easy miles and the long run carry a finish goal. The second is simple to fill. On the Monday of the taper week, after the easy miles, swap the strides for 3 or 4 pickups of about a minute at half-marathon effort with easy jogging between. It keeps race effort familiar without adding fatigue, and it should feel controlled, never hard.
What the science supports
Shifting training emphasis beats unchanging training
This plan breaks into 4 phases. Base weeks establish the habit of easy running at a conversational effort, the kind that builds endurance. Build weeks stretch the long run from 6.5 to 10.5 miles. A cutback week, a planned lighter week, sits every fourth week so tiredness never piles up for long. The taper in week 15 scales volume back before race day. Shifting the emphasis over time like this tends to beat training the same way all 16 weeks, though the edge is small.

Your heart rate drops at the same pace
Steady, continuous running lowers your heart rate at the same easy pace, and for runners starting from a low base the drop is measurable within about 8 weeks. This plan gives you that kind of running from the start, with nearly every mile easy and the Saturday run growing from 4 miles to 10.5. Somewhere in the first 2 months, the same easy runs often start to feel less like work.

Fixed plans need built-in lighter weeks
Weeks 4, 8 and 12 each step back before the next climb, trimming the week's running by a fifth to a quarter. In week 8 the Saturday run drops from 7 miles to 4. Load that keeps building without relief tends to raise the risk of injury and illness, so a runner on a fixed plan needs those lighter weeks written in. How often to place them is coaching practice, and every fourth week sits well inside the usual range.
Strength training lowers injury risk
Strength training sits on Tuesday in weeks 1 through 15, on a day with no run. The consistency matters more than any single session. In a review of 25 trials across many sports, strength training cut injuries to about a third of what groups without it saw. More of it also worked better than a little. The evidence is strongest in team sports and more mixed for running, which makes the steady weekly habit the part to keep.

A real taper sharpens you for race day
Week 15 is when the plan pulls volume back. Your long run drops from 10.5 miles at its week 13 peak to 7, and the Monday and Wednesday easy runs shorten. Race week holds only a 15-minute shake-out, a short very easy run with a few strides, before the half marathon. The drop is intentional. Cutting running by roughly 40 to 60 percent over the last 2 or 3 weeks while keeping some speed tends to help runners race better than skipping the taper.
