Running Plan Review Buena Vida Run Club's 10-Week Run Your First Half Marathon (4 days)
Plan at a Glance
The half marathon is a strange distance to learn on. A 5K hurts the whole way. A marathon takes years to respect. The half sits between them at 13.11 miles. That is far enough to feel real and close enough to learn on. A careful ten-week build can carry a first-time racer to the start line and across the finish. The first week is short and easy. The last week is mostly rest.
What gets a first-time runner across 13.11 miles is the long run more than any other workout. The body needs to learn how to spend two hours on its feet. This plan's long run climbs to ten miles by week 7. Three of those miles are run at race effort, tucked inside the long run so the pace is not brand new on race day. New runners often think speed is the missing piece. They push every easy run a little hard and show up tired. Easy days stay slow enough to hold a conversation.
Buena Vida built this for runners who can already run a few times a week. They want to finish strong, not chase a time. Four running days fit a normal week. Tuesday holds a short strength session. Wednesday is the slightly harder run. Saturday is the long run, and the fourth day stays easy. Week 4 and week 8 step back so the build does not pile up. The taper is short and quiet. Race week is mostly rest.

Our Review
If a first half marathon sits ten weeks out and you can give it four days a week, this plan does the job it claims. The verdict is plain: you finish 13.1 strong, you do not chase a time, and the build does not run you ragged getting you there. The fourth running day over a three-day plan is what buys this version its room to breathe. The long run can grow without crowding recovery elsewhere in the week.
What gets you across the line is the long run more than any other session in the week. The plan answers that with a long run that grows to ten miles in week 7, three of those at race effort tucked inside the peak. Race effort is rehearsed once, and the Wednesday tempo block from week 6 gets the legs used to a steady harder gear. Most beginners try to do every run a little hard and show up tired on race day. The four-day shape gives you room to let easy days stay easy, so the harder day on Wednesday actually lands.
If you're under twelve miles a week right now, build for two or three weeks before week 1. If a finish time matters as much as the finish itself, look at the 5-day version; it adds a second harder midweek run. Week 4 steps back and week 8 cuts back hard. The taper is quiet, and strength holds its slots from week 1 through race week. By race morning, the last three weeks will have left you fresh enough to use what the build added.

Structure
Does the plan build you up smartly?
Four named phases carry you from your first easy run to the start line. Base settles the routine over three weeks. Build is where the long run does the work, climbing to 10 miles by week 7. Then a short taper and a quiet race week bring the legs back fresh. Each phase shift matches a real change in what the week asks of you, and the notes tell you why.
-
Prevention
Does the plan protect you from injury?
Mostly, with a couple of edges left to you. Easy runs stay slow enough to hold a conversation, so the hard days actually land, and a step-back week in week 4 and again in week 8 lets the body catch up. Hard days never sit back to back. Two things hold it short of full marks. A few weeks add mileage faster than the gentle 10 percent rule, and the easy runs do not spell out a warmup, so the first slow half-mile is yours to ease into.
-
Flexibility
What happens when you miss a day?
Miss an easy run and the plan barely notices. Miss the Saturday long run and you are improvising. Every workout carries a priority, so when a week shrinks you can see what to protect (the long run) and what to let go (a short easy day). What you will not find is a written rule for catching up a long run you skipped. That call stays yours.
-
Readiness
Will the plan deliver race-day fitness?
Yes, for a finish rather than a time. The long run climbs to 10 miles in week 7, with 3 of those miles run at half-marathon effort tucked inside, so race pace is not brand new on race day. A short taper leaves you fresh at the line. The one limit: that 3-mile block is your only real taste of race pace, so this build readies you to finish strong, not to chase a target time.
-
Variety
Are the workouts varied enough?
Varied enough to keep the work interesting and purposeful. You meet easy runs, long runs, hill repeats, a progressive fartlek, and short tempo runs, each tied to where you are in the build. The peak long run even folds a race-effort block inside it. The mix leans more on easy and long running than on a wide spread of hard formats, which is the right balance for a first half marathon.

You signed up for something that scares you a little, and you showed up today anyway. That is the whole beginning right there. Some part of you may be quietly 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, to let your body meet the routine, and to notice how it feels to be someone who is in training for a half marathon now.
M 2.5mi Easy Run
First easy run of the plan. 2.5 miles on a Monday at conversational pace, meaning slow enough that you could speak in full sentences without gasping. If you can't speak in full sentences, slow down. The job this week is to land all four runs at this same easy effort.
Tu Strength Training
W 3mi Easy Run
Wednesday is a steady slot through the first five weeks. It only turns into a tempo block from week 6. 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 in this plan is to land 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 the base quietly accumulates, one unremarkable run at a time.
Su Rest
A second week of running on top of a first week is when 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 quietly 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
Week 2 starts with the same gear as week 1, just a touch longer on the long run come Saturday. Breath stays smooth. Resist any urge to push, even on rested legs.
Tu Strength Training
W 3.5mi Easy Run
The Wednesday slot grows half a mile from 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
- You will hit ten miles in week 7 with three at race effort baked into the middle. On race day, your legs have already met that pace once with eight miles already in them.
- Your easy days stay slow enough to hold a conversation. That keeps Saturday's long run sustainable and lets the Wednesday tempo land cleanly when it shows up in week 6.
- Six different run types keep the work fresh, from hill repeats to a progressive fartlek to the race-effort long run, each one tied to where you are in the build.
- You meet hard days well-rested. The midweek tempo and the Saturday long are always separated by a strength day and an easy day, so neither falls into tired legs.
- The fourth running day is what makes weekly volume near twenty miles possible during the build. You get one more easy day than a three-day plan, so the long run is not the only place mileage accumulates.
Weaknesses & Gaps
- If a finish time matters as much as crossing the line, this is not your plan. Race-pace exposure is one three-mile block, and the tempo work is teaching a steady gear rather than building toward a target time.
- You walk into week 1 with ten weeks of runway, which is tight. A missed week in the build is hard to recover from. If your weekly base is under 12 miles, build for two or three weeks before starting.
What's missing
This plan is built to get you to the finish, not to a time. Race pace shows up once. You run three miles at it inside the long run in week 7. The harder Wednesday work teaches the legs a steady gear, not a target time. If a finish time matters to you, the 5-day version of this plan is the better fit. It adds a second harder day each week. Ten weeks is also a tight runway. A missed week in the middle of the build is hard to make up. The safer fix is to repeat last week's long run instead of trying to catch up all at once. If your base is under twelve miles a week, add two or three weeks of easy running before week 1.
What the science supports
Periodization beats constant-load training
This 10-week plan breaks into four distinct phases. Base starts with easy running to establish your aerobic foundation. Build gradually stretches your long run and adds harder work. Taper reduces your volume the week before race day. This structure keeps your body adapting throughout the plan instead of plateauing at the same effort level.
Bradbury et al. 2020; Tønnessen et al. 2014; Casado et al. 2022
Easy aerobic volume is the foundation
Roughly 85 percent of your weekly running stays at easy, conversational pace. This isn't empty time; it's the base your hard days sit on. Your Saturday long runs reach 10 miles by week 7, and that becomes possible only because your Monday and Friday easy runs leave you fresh enough to absorb the work.
Haugen et al. 2022; Casado et al. 2022; Tønnessen et al. 2014
Tapering improves race performance by 2-6%
The last two weeks sharply reduce your running volume while keeping you moving. Week 9 cuts mileage by roughly a third from the previous week. Race week itself drops to mostly rest. Your legs will feel restless on lower volume. That's the taper working. On race morning you show up fresher than you would have if you had trained hard until Friday.
Keep easy days easy, hard days hard
Your Wednesday and Saturday runs are the only clearly hard efforts each week. Wednesday carries a short tempo from week 6 onward, and Saturday holds the long run. The other three running days stay slow enough to hold a conversation throughout. This separation means your hard days arrive with fresh legs instead of meeting fatigue. Easy days are not filler; they're where your body absorbs the work.

Strength training improves running economy
A short strength session lands on every Tuesday throughout the plan. These sessions don't build bulk; they build leg stiffness and neuromuscular control that makes you more efficient at the pace you choose. A stronger runner uses less oxygen at the same speed. By race day, ten weeks of repeated Tuesday strength will have made your running feel more economical at every distance.
