Running Plan Review Buena Vida Run Club's 10-Week Run a Faster Half Marathon (3 days)
Plan at a Glance
Getting faster at the half marathon without chasing a finish time can sound backward, since most speed plans start with a number. Running by effort suits this distance well. Heat, wind, or a poor night's sleep can change what a planned speed feels like over 13.1 miles. Effort already accounts for all of that.
Most of a half marathon runs on your aerobic system, the part of you that uses oxygen to keep moving for a long time. That's why most of your running here stays easy enough to hold a conversation. The faster work sits on top of that base. Tempo running is comfortably hard, the effort you could keep up for about an hour. A common stall comes from running every day at the same medium effort. That middle zone is too hard to recover from and too easy to push you forward.
Buena Vida built this plan for runners who already run about 18 miles a week. It asks for three runs a week across 10 weeks. You start with steady easy running, build toward longer runs and harder sessions, and then ease off for two weeks before race day. Every harder session is described by feel, so you race on effort and meet the clock at the finish.
What follows is Buena Vida's full review of the plan. Every plan is scored against our detailed, 31-point benchmark, drawn from peer-reviewed sports-science research and proven coaching best practices.

Our Review
A half marathon sits on your calendar, and your week has room for 3 runs. 10 weeks is a short runway for that, and this plan spends it well. You climb from 18 miles a week to 30.5, then ease down into race day. The other days hold strength and rest.
The idea underneath is that 3 runs can each do a different job. Once the long runs start, a typical week holds one harder session, one long run, and one easy run finished with strides. Strides are short, relaxed bursts of speed. With only one hard day in 3, you can run that day properly hard and still reach the long run on fresh legs. The harder day moves from tempo, a comfortably hard effort you could hold for about an hour, to hills and a fartlek. A fartlek mixes faster and easier minutes inside a single run.
The real stumble comes out of the cutback. Your running stays near the lighter level for another week, then jumps from 18.5 miles to 28.5 in one step. Hills and a fartlek also arrive together in that in-between week. Strength sits on the calendar twice a week with nothing said about what to do. Half-marathon effort gets only 5 miles of practice before race day.
This suits an intermediate runner who handles 18 miles a week and wants the next half to feel strong past the halfway mark. If you have 12 weeks or more, a longer build spreads that jump out. If 3 runs is what your life holds, run this one, and ease into the big week after the cutback.

Structure
Does the plan build you up smartly?
This build moves in clean stages, from steady easy running to harder sessions and then down toward the race. The opening fortnight stays easy at 18 to 20 miles, and tempo shows up before the long runs do. Cutbacks come every 4 weeks, and the second one starts the taper, the lighter stretch before race day. Race week drops to about 17.6 miles, most of them the race itself.
-
Prevention
Does the plan protect you from injury?
Mostly, with one step to watch. After the cutback, your running stays near 18 miles for another week and then climbs to 28.5 in one go. Add a mile to each run in that in-between week so the climb is smaller. Hills and a fartlek also arrive together that week, both new to your legs. Elsewhere the care shows, with a warm-up and cool-down on every hard session and no hard days back to back.
-
Flexibility
What happens when you miss a day?
With only 3 runs a week, each missed day is a third of your running, so the order of what to keep matters. Protect the long run first and the harder session second, and let the easy run with strides go. If a whole week disappears, repeat it rather than stepping straight into a bigger one. Every harder run is set by effort, so a tired week never leaves you chasing a number.
-
Readiness
Will the plan deliver race-day fitness?
Your race-day fitness comes from 2 places here: tempo that grows from 4 miles to 5, and long runs that reach 12 miles. The 12-mile run carries 3 miles at half-marathon effort, a pacing rehearsal more than a workout that makes you faster. One more 2-mile block at that effort comes during the taper. Long runs of 10 and 10.5 miles in those closing weeks keep the distance familiar.
-
Variety
Are the workouts varied enough?
For a 3-day plan, the range is wide. Across 10 weeks you'll meet easy runs, strides, tempo, long runs, and half-marathon effort blocks. Hills come as 6 repeats of 60 seconds, and the fartlek climbs through surges of 1 to 4 minutes. Tempo does repeat, at 4 miles twice and then 5 miles twice, which gives you a steady way to compare how the effort feels.
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.
You chose a half marathon and decided to get faster at it without chasing a number, and that choice shapes everything ahead. These first days are about finding a rhythm that fits your week. The running should feel easy enough to talk the whole way, and if that seems too gentle, let it stay gentle for now. You are laying the ground the harder weeks stand on. Pay attention to how your legs feel at the start, because that memory makes a useful measuring stick later.
M 6.5mi Easy Run
6.5 miles easy to open the plan. Keep the effort conversational from the first step to the last, slow enough to talk in full sentences. Take stock of how your legs and breathing feel today. This run is the starting mark that every later week gets measured against.

Th 6.5mi Easy Run
Run 6.5 miles easy, matching Monday's distance. If Monday is still in your legs, start slower and let the opening minutes loosen them. You're allowed to ease off on any rise and keep your breathing relaxed. Runs like this one make up most of your weeks here, and they do more for you than their size suggests.
F Rest
Sa 5mi Easy Run
5 miles easy to close week 1. After three runs in six days, some heaviness in the calves or hips is normal and tends to ease once you're warm. A shorter run has a way of pulling you into a faster finish. Keep the whole thing conversational so Monday starts on fresh legs.
Su Rest
The work starts to get real now. For the first time, part of your running asks you to lean into the effort instead of drifting along inside it. That can feel strange after so many comfortable days. Being a little nervous about it makes sense. You don't need to prove anything yet. What matters is learning how hard but controlled feels in your own body, then going home and resting well. Getting faster starts with finding where that line sits for you.
M 7mi Easy Run
7 miles easy, the longest run so far. Find a rhythm you could hold all morning and keep it there. Running this far at an easy effort builds the patience a half marathon asks for. Thursday brings your first harder effort, so arrive at it with this run feeling comfortable.

Th 7mi Tempo Run with 4mi @ Tempo
Warm up 1.5 miles easy, run 4 miles at tempo, and cool down 1.5 miles easy. Tempo means comfortably hard, the effort you could hold for about an hour while speaking only in short phrases. Comfortable and hard sound like opposites, and this run is where you learn they can sit together. Past the halfway point, expect your breathing to deepen and your attention to narrow. You got it right if the last stretch of tempo felt as controlled as the first and you could have gone a little longer.
F Rest
Sa 6mi Easy Run
6 miles easy, two days after your first tempo. The trap here is carrying Thursday's energy into today and drifting toward that harder effort without noticing. Check in often and pull back if talking gets choppy. The easy running between harder days is what lets the next one go well.

Plan Strengths
- You'll know half-marathon effort by feel after holding it for 3 miles inside the 12-mile long run.
- A 5-mile tempo late in the build lets you practice holding a steady hard effort for a long stretch.
- Every hard session opens with an easy warm-up, so the fast part starts on loose legs.
- Coming into race week, strides and a short half-marathon effort block stay, so your legs arrive fresh rather than flat.
- 3 running days leave 4 days for strength, rest, and everything else your week holds.
Weaknesses & Gaps
- Your legs take a 10-mile jump in a single week after the cutback, from 18.5 miles to 28.5.
- Two unfamiliar hard sessions, hills and a fartlek, share a single week, so soreness from the hills can carry into the fartlek.
- You're on your own for strength, even though it sits on the calendar twice a week.
- Half-marathon effort gets only 5 miles of practice, so pacing the opening miles may take some guesswork.
What's missing
The week after the cutback stays light, so the next one asks for 10 more miles at once. Add about a mile to each run in that lighter week and the jump shrinks to something your legs can absorb. That same week brings hills and a fartlek together, both new. Run the fartlek surges at the gentle end of the effort, or swap it for an easy run with strides if the hills left you sore. Strength shows up twice a week with no content, so pick a routine you can repeat and keep it off the tempo days. Race effort gets little rehearsal. On one easy run late in the build, spend a mile or 2 near half-marathon effort so the opening miles of the race feel known.
What the science supports
Keep easy days easy, hard days hard
Most distance runners improve more by keeping easy days truly easy and hard days clearly hard, rather than running everything at a middle effort. Studies of trained runners back this split firmly. Here, the 5-mile tempo and the 6 hill repeats sit between runs slow enough to talk through. You come to each hard day with legs that have had time to recover.

Easy miles do most of the work
Easy running makes up most of a runner's week, and it is the base that carries the harder sessions. The evidence for this is strong across trained runners. About 84% of your miles in this plan are easy, from the 6.5-mile opening runs to 10.5-mile long runs late in the build. That easy base is what lets the tempo and hill days be hard.

Strides and sprints make you more efficient
Strides, short and relaxed bursts of speed, help distance runners move more smoothly at every pace. Trials in recreational and trained runners support them well, and most of the effect comes from how the legs coordinate. In this plan, 4 strides of 100 m finish an easy run most weeks from the build through the taper. They cost a few minutes and leave little fatigue behind.

Varied intensity beats a steady moderate pace
Mixing easy running with clearly hard efforts builds endurance better than weeks of steady, medium-hard running. Research across recreational and trained runners supports this. Your harder days here change shape, from 60-second hill repeats to a fartlek of surges from 1 to 4 minutes and tempo blocks of 4 and 5 miles. The running around them stays easy, so no grey middle effort fills the week.

A taper makes you 2-6% faster on race day
A taper, 1 to 3 weeks of lighter running before a race, improves race results for trained runners compared with training straight through. Research puts the effect at a few percent. This plan steps down from 30.5 miles to 23.5 and 25, and race week sits near 17.6 with the race included. Strides and a 2-mile half-marathon effort block stay in, so your legs keep some snap.
