Plan at a Glance
Most people who sign up for a first half marathon carry the same worry. You've never run 13.1 miles, so how will you know you can? This plan's answer is that you won't run the full distance until race day, and you won't need to. The idea that you have to cover the distance first comes mostly from marathon lore about the 20-miler. The long run here grows on Saturdays to 10 miles, and for a half, a long run of an hour and a half to two hours is what the distance asks of you in training. For most first-timers, the rest, the taper and the race itself are where the last 3 miles come from.
The week has a simple shape. You run 4 days: an easy run Monday, a midweek run Wednesday, a short run Friday (with strides once the base settles) and the long run Saturday. Tuesday is a short strength session, and Thursday and Sunday stay open, which fits a working week. The easy running comes first, at the pace you can talk at, and Friday stays short so Saturday starts on fresh legs. If you tend to run every easy day a little hard because it feels like progress, this is where you stop. Once the base is in, the harder work arrives: a hill session, a fartlek, and a Wednesday tempo run, the comfortably hard gear where short phrases come out but full sentences don't. Most beginners overcook that first tempo. Two lighter weeks step back along the way.
The moment that matters most comes on the biggest Saturday, when the 10-miler carries 3 miles at half-marathon effort in the middle. It's your one rehearsal. Treat it as a time trial and you learn the wrong pace and carry tired legs into the easier week after. Run it level, the same effort at the third mile as the first, and you'll know what race effort feels like before race day.
The stretch to watch is the middle, where the long run grows and the harder sessions show up in the same weeks. Keep the easy days easy there, slower than you think they need to be. For a runner who already gets out a few times a week and wants a first half that feels like a finish, this plan builds the long run, protects it with easy days, and rehearses race effort before you need it.
Below is Buena Vida's full review of this plan. We hold every plan to our detailed, 30-point benchmark, with each measure pulled from peer-reviewed sports-science research and proven coaching best practices.

Our Review
Already running about 12 miles a week across 4 runs, you have enough to start a first half marathon, and this plan builds on it steadily and well. Its strength is the easy running and the long run. Nearly every mile is at a talking pace, and the long run grows steadily from 4 miles to 10, peaking three weeks before race week. The harder sessions wait until the base is in and never land on back-to-back days, so each one gets fresh legs. The middle stretch is where it asks the most, with mileage climbing and new kinds of hard work arriving at the same time. Race week is the other place to plan around: a 1-mile run and a 15-minute shake-out are all that stand between the last long run and the race, so if your legs feel flat, add an easy 20 to 30 minutes early in the week. Run it, and take that stretch a notch gentler than the calendar suggests.

Structure
Does the plan build you up smartly?
Sound in shape, from the first easy week to race week. Base, build, taper and race week follow in order, and the hard work changes as they go, from hills and a fartlek early in the build to tempo runs late in it. Each of its 5 hard sessions spells out the warm-up, the work and the cool-down, and says why the session is there.
-
Prevention
Does the plan protect you from injury?
Mostly, with one week to handle carefully. Close to nine miles in ten are easy, each of the 5 hard sessions starts and ends with easy running (1 mile either side of the hill repeats, 0.5 mile around each tempo run), and none sits the day after another. Strength sits on Tuesday every week until race week, and strides and hills are on the calendar. Weeks 4 and 8 pull the mileage back, to 12.5 and 17 miles, so the build gets two breaks. The soft spot is load. In week 6 the first tempo run and a 9-mile long run arrive together, and the load climbs faster than in any other week. Week 5 does a smaller version of this, bringing in the hills and the fartlek while the volume goes up. Fitness from weeks 5 and 6 shows up in your breathing first, while the tendons and bones carrying you through that 9-miler need longer. That stretch deserves a lighter touch than it looks like it needs. Jumps like that are when injury risk tends to rise, so treat a new ache that week as a signal to ease off rather than something to push through on the way to Saturday.
-
Flexibility
What happens when you miss a day?
Saturday's long run is the session to protect, and so is Wednesday once it turns into a workout. The other runs are the flexible ones, including the Monday hill session when it comes. If a day goes sideways, drop one of those rather than shuffling the long run. Don't make up a missed run by stacking it onto the next day, and don't slide Wednesday's tempo to Friday, since Friday is there to put fresh legs under Saturday. If a whole week slips away, run it again before stepping up to the next Saturday's distance.
-
Readiness
Will the plan deliver race-day fitness?
For a first half, it builds what the race asks for. The biggest week reaches 20 miles and the long run reaches 10, the right size for the distance, and that peak lands three weeks before race week. Tempo and threshold work runs from week 5 through week 8, and the 10-miler carries 3 miles at half-marathon effort as a rehearsal. Run that block level rather than as a time trial, or you learn the wrong pace and carry tired legs into the cutback. The taper cuts deep: race week is a 1-mile run and a 15-minute shake-out before the race, which keeps race week restful, though some runners feel flat on so little.
-
Variety
Are the workouts varied enough?
A first half gets all the range it needs here. Easy runs, long runs, strides, a hill session, a fartlek, three tempo runs and the race give the weeks real texture. The hard work comes in only three formats, though, and most of it runs on feel (the talk test, short phrases) rather than a pace, with half-marathon effort named only once. For a first-timer that's a fair trade. You learn to read effort, and effort is what you'll race on.

A first half marathon can look a little scary from this side, and you showed up today anyway. That is the whole beginning right there. Some part of you may be wondering whether this was actually for you, and the answer is going to come slowly, in the form of one ordinary run after another. There is nothing to chase yet. The work this week is simply to start and to let your body meet the routine. Notice how it feels to be someone in training for a half marathon now.
M 2.5mi Easy Run
2.5 miles easy, slow enough that you could speak in full sentences without gasping. The opening run of a plan carries a little extra nerve, and that is normal. If you can't speak in full sentences, slow down. The job this week is to keep all 4 runs at this same easy effort.
Tu Strength Training
W 3mi Easy Run
3 miles easy. The Wednesday run stays easy for now and becomes a tempo run later in the build. The job today is to find the easy gear and stay there.
Th Rest
F 2.5mi Easy Run
Friday short run before tomorrow's longer effort. Loose and slow. The point of the Friday slot is to reach Saturday with legs that have not been pushed.
Sa 4mi Easy Run
Conversational the whole way. The point is to teach the legs what a steady, longer effort feels like. Should feel ordinary at the end, like you could keep going. Miles like these are where your base builds, one easy run at a time.
Su Rest
A few runs into the plan, your body starts to suspect that this is not a phase. Your legs might feel a little heavier than you expected, or surprisingly fine, and either one is okay. Underneath what you can feel, things are shifting in your favor. The heart is getting more efficient, the tendons are learning the new load, and the easy pace is slowly becoming easier. Keep the easy stuff easy, and trust that even the days that feel small are doing something real.
M 3mi Easy Run
3 miles in the same easy gear as before. The long run grows a touch come Saturday. Breath stays smooth. Resist any urge to push, even on rested legs.
Tu Strength Training
W 3.5mi Easy Run
3.5 miles easy. That is a little longer than Monday's run. Stay relaxed. The breath should never feel tight. The body warms into the gear over the first mile. Do not chase pace.
Th Rest
F 2.5mi Easy Run
Short and gentle. The legs may feel heavy from earlier in the week, and that is normal at this stage of the build. Slow start, slow finish. A run this short exists to keep the legs in motion without spending anything. If the pace drifts slower than expected, let it.
Sa 5mi Easy Run
Stay in the gear where you could keep talking. The first mile may feel sluggish. That is normal and usually clears by mile two. Finish feeling like more was available.

Plan Strengths
- Easy running carries the plan: even in the 20-mile peak week, the only hard running is Wednesday's tempo and the half-marathon block inside Saturday's 10.
- The long run builds steadily to 10 miles and peaks three weeks before race week.
- Hard sessions wait until the base is in, never fall on back-to-back days, and each one opens with a warm-up.
- Two cutback weeks (4 and 8) and four clear phases give the build a shape you can feel.
- A 3-mile block at half-marathon effort inside the 10-miler rehearses race day.
Weaknesses & Gaps
- Weekly mileage jumps sharply twice, into week 3 and again into week 6.
- New hard sessions arrive in weeks when volume also climbs: hills and a fartlek in week 5, the first tempo in week 6.
- Race week drops to a short run and a shake-out, a deep cut that can leave some runners feeling flat.
- Most of the hard work is prescribed by feel, with a single block tied to half-marathon pace, and it comes in only three formats.
What's missing
Weeks 5 and 6 are where you'll most want a cushion, and race week is where you may want a little more running. In week 5 the long run jumps to 8 miles in the same week the hills and the fartlek arrive. If your legs are sore, run Monday's hills as an easy run and keep Wednesday's fartlek, so only one new session lands that week. In week 6, keep the easy days slower than feels necessary around the first tempo. Race week has very little running before the race, and if your legs feel flat, an easy 20 to 30 minutes on Monday keeps them awake without costing you anything. And if you'd like a second taste of race effort, running the last 1 to 2 miles of the 7-mile long run in the taper at half-marathon effort is an option, the kind of faster touch a taper can keep.
What the science supports
Shifting training emphasis beats unchanging training
This 10-week plan breaks into four distinct phases. Base building fills weeks 1 to 3 with easy running that sets the foundation. The build, weeks 4 to 8, stretches the long run to 10 miles and adds hills, a fartlek of surges that grow longer, and tempo runs, sustained efforts where only short phrases come out. One lighter taper week follows, then race week. Shifting the emphasis across phases like this tends to beat training that never changes, though the measured gain is small.

Easy miles do most of the work
About 88 percent of your running stays at an easy, conversational pace, slow enough to speak in full sentences. The best distance runners also keep most of their running easy, and recreational runners hold the same balance at lower mileage. That easy running is the base your hard days sit on. Your Saturday long runs reach 10 miles by week 7, and the easy Friday run before each one keeps your legs fresh for it.
A real taper sharpens you for race day
Volume eases from the 20-mile peak in week 7 to about 15.5 miles in week 9, a cut of roughly a quarter, and the long run steps down from 10 to 8 to 7 miles. Race week holds just a 1-mile run and a 15-minute shake-out before Sunday. Trimming running by roughly 40 to 60 percent over the final weeks, while keeping a little speed through short strides, improves race performance compared with not tapering.
Blood and tiny vessels change first
Hard work waits until week 5, after four weeks of easy running, the order beginners are advised to follow. Then hill repeats, short hard climbs, land on Monday and a fartlek on Wednesday, and tempo runs, steady efforts where only short phrases come out, hold Wednesday in weeks 6 to 8. In newer runners, easy opening weeks like these tend to raise blood volume and grow fresh capillaries, the tiny vessels that feed working muscle.
Fixed plans need built-in lighter weeks
The running drops back twice, to 12.5 miles in week 4 and 17 in week 8, with the long run easing to 5 and then 8 miles. Load that keeps piling up with no break tends to raise the risk of injury and illness. A runner on a fixed plan has no coach to call a lighter week, so this plan writes both into the calendar.
