Plan at a Glance
If you've raced a half and come up a little short of 1:30, there's a fair chance the race was lost late. The first 10 miles went to plan, and then the same pace started costing more each mile, a few seconds at a time. It's tempting to read that as a speed problem. Often it's endurance, running out a few miles before the finish line does.
This plan works on those late miles. Goal pace arrives at the start and never changes. What changes is how long you hold it and what surrounds it. The Tuesday reps stretch from half-miles to full miles. Thursday's run at 10K effort grows by a couple of miles. The Saturday long run climbs to 15, and Sunday brings a medium-long run on Saturday's legs, so the closing miles of race day feel like ground you've already covered tired. The build comes in three climbs rather than two, and the third is where the biggest pieces live: a long rehearsal at goal pace, the 15-miler, and the heaviest week of running, all on legs with two full climbs underneath them.
It suits runners who have raced a half before and already run about 35 miles a week. It trains 5 days, with strength on Wednesday and Friday off. Most of the miles are easy, and they have to be. By the biggest week, Monday's easy run is longer than the first long runs were, and it only does its job if it stays slow enough to talk through.
Here is Buena Vida's full review of the plan. We measure every plan against our detailed, 30-point benchmark. Each standard is drawn from peer-reviewed sports-science research and proven coaching best practices.

Our Review
The most unusual day in this plan's week is Sunday. Most runners are used to resting the day after the long run, a reward for the week's one big effort. Here Sunday is a medium-long run on Saturday's legs, every week, and that pair is how the plan builds a back half you can hold without asking for a 20-mile run. Around it, goal pace stays fixed from the first week to race week while the reps get longer, and Thursday's 10K-effort run grows in step. Goal-pace work and threshold running are different kinds of training. Neither has been shown to beat the other, so getting both every week is a sound way to prepare. The third climb is what sets this plan apart from shorter versions of the same goal: it holds the race simulation, the 15-miler and the biggest week, run on legs with two climbs already behind them.
The gap is small. The emphasis stays the same from start to peak, with the build growing the work rather than changing it. What the plan builds, week after week, is a runner for whom mile 11 is ordinary ground.

Structure
Does the plan build you up smartly?
Yes, with one gap: the build lengthens its sessions without ever changing what they train. Tuesday's goal-pace reps and Thursday's 10K-effort run carry every climb from the first week to the peak. The phases are named and explained as you go, but they grow the work longer rather than handing over to a block with a new purpose. What each session asks is never in doubt. All 25 hard sessions come written out with a warm-up, the main work, a cool-down and a note on what the session is for.
-
Prevention
Does the plan protect you from injury?
Thoroughly, with each hard day given room on both sides. Tuesday's reps and Thursday's 10K-effort run each start with a warm-up and sit a day apart, and Monday and the Sunday medium-long stay conversational, so most of the running is easy. Strength sits on the calendar every Wednesday until race week. Weekly volume climbs in three stages, and a cutback every fourth week pulls it back before the next climb starts higher. The first week back from the first cutback is the busiest of the build, so keep its easy days truly easy.
-
Flexibility
What happens when you miss a day?
Less than you'd fear. The week has a clear shape: goal-pace reps on Tuesday, 10K effort on Thursday, the long run on Saturday. Those three carry the plan. If life takes a day, give it Monday's easy run or Sunday's medium-long. Inside a climb, the hard week repeats, so a missed Tuesday comes back the next week in the same form and there's no need to cram it into Wednesday. If the miss falls in the week before a cutback or before race week, let it go. Neither is a place to catch up. Friday's rest day gives room to slide a session by a day, as long as two hard days don't end up touching. If most of a week goes, count it as that climb's cutback come early, and pick up the following week as written.
-
Readiness
Will the plan deliver race-day fitness?
It's aimed squarely at the part of the race that usually decides a sub-1:30. Peak week sits well inside the right range for the goal, and the long run reaches 15 miles, past race distance. Goal pace gets steady practice the whole way, from half-mile reps early to a 6.8-mile race simulation in week 11 and full-mile reps that hold through the taper. The two-week taper does what a taper should: volume falls while the goal-pace reps stay, which tends to bring a better race than full training would.
-
Variety
Are the workouts varied enough?
Nine kinds of session, a wide spread for a half marathon plan. Across the plan you'll run easy runs, medium-long runs, long runs, goal-pace reps at three lengths, threshold runs at 10K effort, two progression runs that finish at goal pace, a race simulation, a short race-week tune-up and strides. The variety has a purpose. Each session comes back often enough that you can feel it change under you. The mile reps that take real focus the first time they appear are meant to feel like a known pace by the taper, and that shift is part of the training.
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've signed up for 16 weeks aimed at a specific time, and this opening stretch is just about getting your body inside that intention. Nothing here should feel heroic yet. The easy days set a floor, and the harder days teach your legs what the coming weeks will keep asking of them. Settle in, find your rhythm with the schedule, and let these early days feel ordinary on purpose. The hard part starts arriving on its own soon enough.
M 6mi Easy Run
6 miles easy. The first run of the build. Conversational the whole way, no faster than you could hold while talking. The job today is to set the floor for what easy means across the 16 weeks. Every Monday after this one inherits the pace you choose now.
Tu Intervals: 6×0.5mi @ ½ Marathon
Warm up 2 miles, run 6 × 0.5 mile at 6:49/mile with 400 m of easy jogging between, and cool down 2 miles. The first interval session of the plan. The half-mile reps are short on purpose. The aim is for the legs to recognize 6:49/mile as a pace they can find without searching for it. The trap on rep 4 is wanting to push the jog recoveries faster than the prescription. Hold the 400 m jog at jog pace. A clean session ends with rep 6 matching rep 1 in pace and form.
W Strength Training
Th 6.8mi Threshold Run with 3.8mi @ Threshold
Warm up 1.5 miles, run 3.8 miles at 10K effort, and cool down 1.5 miles. The first threshold session of the plan. 10K effort is the pace you could hold for about 40 minutes flat-out. It's a touch slower than the 10K race pace you'd run today. The block grows across the build, but today it's a baseline. Notice what 10K effort feels like on Thursday legs. That sensation is what mile 9 of the race will ask you to find. Comfortably hard means a few words at a time, never full sentences.
F Rest
Sa 8mi Long Run
8 miles at fully aerobic effort. The first long run of the plan. Long runs across this build accumulate by volume rather than intensity. The pace doesn't matter today. The duration does. Set the floor here. From here the long run climbs to 15 miles before the taper. Plan the route before you start, since long runs go better with logistics handled.
Su 5.5mi Medium-Long Run
First medium-long. 5.5 miles easy on Sunday, the day after the long run. The point of the medium-long isn't the distance. The legs are learning to run easy the day after they already ran long. Resist the urge to make this run feel like training. It's part of the long run, splayed across 2 days.
You are still inside the opening stretch, where the work is laying groundwork that will only show its hand later. The legs should feel like they are catching up to the schedule rather than running ahead of it, and that is the correct shape for now. Stay patient with the easy days. Plenty of the work ahead is going to ask for sharpness, and the engine that delivers it is being built right here in the ordinary weeks.
M 6.5mi Easy Run
Second easy Monday. Same effort, slightly more volume. By the back end of cycle one, this run grows another mile. For now, the only goal is to keep Monday genuinely easy. Tuesday's intervals are faster on legs that respected Monday.
Tu Intervals: 6×0.5mi @ ½ Marathon
After a 2-mile warmup, run 6 × 0.5 mile at 6:49/mile with 400 m jog recoveries, and cool down 2 miles. The same half-mile set comes around again, and the reps should sit a touch easier today. Splitting goal pace into short pieces lets you practice it with good form before fatigue gets a say. Keep the jogs truly easy so the closing reps run as cleanly as the opening ones. Most runners find rep 3 is where the rhythm clicks. A set with no fade from start to finish did its job.
W Strength Training
Th 7mi Threshold Run with 4mi @ Threshold
Warm up 1.5 miles, run 4 miles at 10K effort, and cool down 1.5 miles. The threshold block grows a little each week through this opening cycle. Pace doesn't change. What's changing is your tolerance for time at the effort. Ease into the effort over the opening few minutes rather than starting at full pressure. Most runners feel their breathing find a steady pattern once the block is underway. The session was a success if the final stretch held pace without the form unraveling.
F Rest
Sa 8.5mi Long Run
8.5 miles long run, fully aerobic. The ladder moves up one rung today. Long runs accumulate fitness through volume at this stage. Stay patient in the back half, where the pace tends to creep up on its own without asking permission.
Su 6mi Medium-Long Run
6 miles easy on Sunday. This is the workout itself, the second leg of Saturday, run on legs that covered 8.5 miles yesterday. Keep the pace conversational even if the legs feel stiff early. Most runners loosen up after the opening couple of miles.

Plan Strengths
- Goal pace never moves, so you practice it for months. The reps grow from half-miles to full miles, and the race simulation holds it for 6.8 miles.
- The Saturday long run and Sunday medium-long build late-race endurance without asking for a 20-mile run.
- A third climb gives the race simulation, the 15-miler and the biggest week two full climbs of groundwork underneath them.
- Each of the 25 hard sessions has a warm-up and a stated job, and Wednesday keeps Tuesday's and Thursday's work apart.
- The two-week taper cuts volume but keeps the full 1-mile goal-pace reps right up to race week.
Weaknesses & Gaps
- The emphasis never shifts: Tuesday's goal-pace reps and Thursday's 10K-effort run do the same jobs from the opening week to the peak.
- You'll get little practice at fast, relaxed running, since nothing runs faster than 10K effort until race week's strides.
- A runner arriving below about 35 miles a week will feel the build most, because the plan opens there and climbs. Start the plan already running that much.
What's missing
Strides show up only in race week, and nothing else on the calendar runs faster than 10K effort. That's a choice rather than a hole, and it's a cheap one to build on: 4 to 6 relaxed strides of about 20 seconds at the end of one easy run a week, starting in the first month, cost almost nothing and keep quick running familiar. The routes are left to you, and in a coach's view a rolling course for the Sunday medium-long is a good habit if one is nearby. If an ache does keep you off running for a few days, the Thursday sessions are the first thing worth bringing back once you're running without pain.
What the science supports
Shifting training emphasis beats unchanging training
Build and cutback cycles, with lighter weeks at weeks 4, 8 and 12, carry the plan through five named phases: base, build, peak, taper and race week. Each climb tops out higher than the last: 38.7 miles in week 3, 48.8 in week 7, 56.8 in week 11 and 59.4 in week 13. Training that builds and changes like this tends to beat holding one load the whole way, whichever model a plan follows.

Longer long runs go with faster marathons
Long runs peak at 15 miles, nearly 2 miles past race distance. By week 13, the Saturday long run has climbed from 8 miles through 12.5, 13 and 14 before reaching 15, so mile 11 of the race isn't new territory. Going past race distance is common half marathon practice. The research behind it comes from marathoners, where longer long runs tend to go with faster finishes. No study has yet tested whether shorter, faster sessions could stand in.
Doherty et al. 2020; Fokkema et al. 2020; Toresdahl et al. 2022
Sharp running-load jumps raise injury risk
Within each block, weekly mileage rises by about 3 to 6 percent at a time, and the cutback weeks at weeks 4, 8 and 12 trim it by about 26 to 30 percent. Each climb then starts higher than the last, after the lighter week rather than on top of a heavy one. Big jumps in running load tend to raise injury risk. The clearest case is a single run well past your longest of the past month, and this build adds its distance in steps instead.
Easy miles do most of the work
About 80 percent of this plan's running is easy: the Monday run that grows from 6 to 11.5 miles, the Saturday long run, the Sunday medium-long run, and the warm-ups and cooldowns around the hard sessions. Elite distance runners do about 80 percent or more of their running at a conversational effort, and recreational runners use the same balance at lower mileage. That easy base is what carries the Tuesday intervals and Thursday threshold runs.
A real taper sharpens you for race day
The 2-week taper trims volume from the 59.4-mile peak to 48.6 and then 41.3 miles, and race week drops to 15.1 miles before the race. Tuesday's 6 by 1 mile at goal pace keeps its full length through both taper weeks, while the long run steps down from 15 miles to 12 and then 10. Cutting volume by roughly 40 to 60 percent in the last week or two while keeping some speed improves race performance compared with not tapering.
