You don't have to run 13.1 miles before race day to run 13.1 miles on race day. The longest run here is 10, and it comes with a few weeks to spare. The biggest week of training adds up to 17.5 miles, which means race morning is nearly a whole big week in one go. The weeks between that long run and the start line are where your body catches up with everything you've asked of it.

This plan is for a runner who already covers about 8 miles in a normal week and has three days to give: Monday, Wednesday and Saturday, with a strength session on Tuesday. It starts at the mileage you already run. From there the Saturday run does the climbing, mostly half a mile or a mile at a time, and a lighter week comes around every few weeks. That pacing matters more than it looks. Your heart and lungs adapt within weeks. Tendons and bone take months. Feeling ready for more isn't proof the slow parts of you are ready, so the miles grow at their speed, not your enthusiasm's.

Monday and Wednesday are easy runs nearly every week, at a pace where you can talk in full sentences. It will feel too slow at first. Somewhere among those easy Mondays and Wednesdays, that same pace starts to feel easier, and that's the first sign it's working. More often than not, the run that undoes a Saturday is the Wednesday before it, the one that drifted a little fast because you felt good. The plan says so itself on the easy run before the biggest long run: a slightly hard easy day costs you on Saturday.

In the middle stretch a fartlek and a hill session show up, with short strides on most Mondays. The biggest week puts a few miles at half-marathon effort inside the long run, so you practice race rhythm on legs that already have miles in them. Then the running drops away so race week is light.

Our full review of the plan follows. We grade every plan on the same 30-point benchmark, with each measure drawn from peer-reviewed sports-science research and proven coaching best practices.

Our Review

Rank S

If you said yes to a half marathon before you fully believed you could run one, this plan was built for you, and it's an easy one to recommend. It starts at the mileage you already run, asks for three days a week, and lets the Saturday long run carry you to 10 miles, with a stretch at half-marathon effort inside it so race rhythm isn't new on the day. A lighter week comes around every fourth week or so, and nearly everything else stays easy, so the long run always gets fresh legs.

The gaps are small, and each is a demand a first-timer can meet. The biggest step up in running comes in week 7, the hill session debuts in a week when mileage is also climbing, and race week is nearly empty before the shake-out. Two harder sessions in the whole plan is the tradeoff that keeps three running days easy to recover from. None of it changes the verdict. Run it, and aim to cross the line feeling like a runner rather than a survivor.

  1. Structure

    5/5

    Does the plan build you up smartly?

    Patiently, in four clear phases: a base month near your current mileage, a build where the long run does the climbing, a taper, and race week. If 6 miles is the farthest you've ever run, you'll pass it in week 5, after a month of building toward it. The harder sessions wait for the build, with the fartlek in week 5 and the hills in week 6, so the base month asks for nothing harder than strides. Week 9 is the peak. Keep Monday and Wednesday truly easy that week, because Saturday's 10-miler is what the week is for.

  2. Prevention

    5/5

    Does the plan protect you from injury?

    This plan guards a first-timer's legs by keeping almost everything conversational, with the fartlek, the hill session and the race-effort block in the 10-miler as the only exceptions. The two harder sessions land on a Monday and a Wednesday, well clear of Saturday's long run, and each opens with a warm-up and closes with a cool-down. Lighter weeks in weeks 4, 8 and 11 break the build into short climbs, so the running never piles up for long without relief. The biggest step up in running comes in week 7, when weekly mileage goes from 12 to 15. If something aches that week, trim the Monday run and keep Saturday. The hill repeats also arrive for the first time in week 6, the same week the long run reaches 8 miles, so a new kind of effort shows up alongside new distance. Run the hills by feel and stop a rep early if your form starts to slip. If you're carrying an old niggle from the last time you did too much, it's worth noticing. Many runners find a lingering low-grade ache is an early signal, and a few days of clearly lighter running is a sensible precaution, not a full stop.

  3. Flexibility

    5/5

    What happens when you miss a day?

    On three running days with space between them, a missed run is easy to absorb, and life will take one from you at some point. The plan marks the Saturday long run as the session that matters most, the Monday and Wednesday runs next, and Tuesday's strength session after that. When a week goes sideways, protect Saturday. Slide a missed Monday or Wednesday run a day later if your week allows, but not into Friday, and don't tack its miles onto the long run. If you miss a long run, pick up with the next one on the schedule instead of trying to make up the distance. The lighter weeks give you natural places to regroup.

  4. Readiness

    5/5

    Will the plan deliver race-day fitness?

    The build here is the right size for a first-timer chasing a strong finish. A 17.5-mile peak week and a 10-mile long run are where they should be for a first half, and the long run peaks three weeks before the race, with time left to recover. That 10-miler is also the dress rehearsal, with 3 miles at half-marathon effort in the middle. Treat that block as pacing practice, not a fitness test. The taper is where the plan gives up a little ground. Weeks 10 and 11 step down sensibly, but after the last long run on the Saturday of week 11, the next run is the Friday shake-out six days later, with five days of no running in between. For a first-timer, that long a gap before the biggest run of their life can mean stale legs and a buzzing head. Most first-timers find one short easy run early in race week settles both.

  5. Variety

    5/5

    Are the workouts varied enough?

    Well judged for a first half. Across the plan you get easy runs, long runs, strides on most Mondays from week 3, a progressive fartlek, a hill session, a long run with a race-effort block, and the race. The 6 × 60-second hill repeats come written out in full, warm-up to cool-down, and so does the progressive fartlek, each with a note on why it's there. The thin part is the count: two harder sessions in all, in two formats. Effort cues lean on feel (conversational, comfortably hard), and half-marathon effort is the only named pace, so learning what each effort feels like is part of your job. For a first-timer aiming to finish, that's a fair trade.

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 said yes to something hard, and these runs are what saying yes looks like. The body underneath the running shoes does not need to feel impressive yet, and the work ahead does not need to feel fast or graceful. It just needs to happen, and you need to come back the next day. That is the whole job in front of you for now. If part of you is wondering whether you really belong inside a training plan, you do, and the wondering will settle down on its own as the weeks accumulate.

    Conversational pace the whole way. If a full sentence still flows at this pace, the effort is true. Resist the urge to push. The easy days are where consistency lives.

Plan Strengths

  • Starts at the 8 miles a week you already run and builds in small steps, with lighter weeks in weeks 4, 8 and 11.
  • The long run climbs from 4 miles to a 10-mile peak three weeks before the race, so it's well behind you by race day.
  • The 10-mile long run doubles as a race rehearsal, with 3 miles at half-marathon effort in the middle.
  • Weekday runs top out at 4 miles and stay easy, so Saturday's long run gets the fresh legs it needs.
  • Both harder sessions are fully written out with a warm-up and cool-down, and no hard days sit back to back.
  • Strides on most Mondays keep some speed in your legs on a three-day week.

Weaknesses & Gaps

  • Training load rises most sharply in week 7, when weekly mileage goes from 12 to 15.
  • Hill repeats appear for the first time in week 6, a week when mileage is also climbing.
  • Only two harder sessions in the whole plan, in two formats.
  • Race week is nearly empty: five days with no running between the last long run and the Friday shake-out.
  • Pace guidance is mostly by feel, with half-marathon effort the only named pace.

What's missing

A few things are left to you, and each is easy to cover. Race week has no running between the last long run and the Friday shake-out, so add a 20- to 30-minute easy run with a few strides on Monday or Tuesday to keep your legs awake. Pace guidance is mostly by feel, so use the talk test on easy days (full sentences, no gasping), and use the half-marathon effort block in the 10-mile long run to learn what race effort feels like, then carry that feel to the start line. And with only two harder sessions, this plan is built for finishing. If you want to race for a time, a plan with more running days and weekly workouts will suit you better.

What the science supports

Shifting training emphasis beats unchanging training

The plan divides into four clear phases: Base (weeks 1 to 4), Build (weeks 5 to 10), Taper (week 11), and Race Week (week 12). Each phase has a different job. The base builds the habit. The build stretches the long run toward the finish line. The taper lets your legs come back to life. The race week keeps your legs loose for the start. Plans built in phases like this tend to beat plans that hold one load the whole way through.

A real taper sharpens you for race day

In the last two weeks, the plan steps back on purpose. Week 11 drops to 12.5 miles from the 17.5-mile peak and the long run shrinks to 7 miles, then race week holds only a 15-minute shake-out before the half. Strides, short relaxed bursts of speed, stay in both weeks. This taper isn't the training ending. Easing off this way while keeping some speed improves race performance compared with training straight through to race day.

Bosquet et al. 2007; Wang et al. 2023

Start at the mileage you already run, not the peak

Week 1 asks for 8 miles over 3 runs: 2 miles on Monday, 2 on Wednesday and 4 on Saturday. That matches the 8 miles a week the plan expects you to bring, and the 17.5-mile peak waits until week 9. Starting near what a runner already handles is a principle drawn from expert guidance and how trials are set up, though no study has tested it directly. Here it means your first week should feel familiar.

Vora et al. 2018; Schuster et al. 2025; Roberson et al. 2018

Threshold or race pace: neither proven better

For recreational runners, race-pace work and threshold work are different kinds of training, and either is a reasonable choice, since no study shows one beats the other. This plan uses race effort as a rehearsal: one 3-mile block at half-marathon effort, the effort you could hold for the whole race, tucked inside the 10-mile long run in week 9. Easy miles carry the weeks around it.

Smyth & Muniz-Pumares 2020; Jones et al. 2021; Vickers & Vertosick 2016

Fixed plans need built-in lighter weeks

Cutback weeks, planned lighter weeks, follow each climb. Week 4 drops to 8 miles after 11, and week 8 drops to 12 after 15, keeping the 8.5-mile long run but trimming the weekday runs to 2 and 1.5 miles. Training that keeps building without relief tends to raise the risk of injury and illness. On a fixed plan with no coach watching, a scheduled lighter week is the simplest way to build that relief in.
