Plan at a Glance
Two worries usually come with a goal like this one. The race is 13.1 miles, which is a long way, and you're not sure you're fast enough. This plan takes on the first and mostly sets the second aside. A sub-2:30 half asks for a pace that's steady, not fast, and slower than a tempo run. What decides your day is whether your legs are still turning over smoothly in the last few miles.
So it starts gently. Four runs a week, every one at a pace you can talk at, with short, relaxed strides once the routine settles and two short strength sessions on the days in between. None of the plan's harder sessions shows up until nearly half the calendar has passed. That can feel strange if your picture of training comes from what people post: splits, workouts, race photos, and nobody sharing a 1.5-mile jog. Those jogs are the work. Saturday carries the long run, growing a little at a time, and a lighter week comes around every few weeks so the running has room to sink in.
Then the harder work arrives in layers. A single fartlek wakes the legs up. A few Fridays of tempo follow, comfortably hard, where talk comes in short phrases. Then goal pace, practiced a handful of times before race morning.
Watch for the first of those goal-pace runs. After the tempo Fridays, it will feel too easy, and you'll want to run it faster to bank something. Don't. Holding a pace that feels like too little is the skill race day asks for, starting with a first mile that should feel slower than seems right.

Our Review
A newer runner chasing a sub-2:30 half should run this plan. Goal pace for this target sits below threshold, so the fitness comes from easy miles, a Saturday long run that climbs steadily to 11 miles and a few tempo Fridays, while the goal-pace runs late in the build teach you what race day feels like. The plan is put together in exactly that order: seven weeks of nothing but easy running and strides, then one new kind of harder work at a time, each arriving on legs that have met the one before. The gaps are small, and each one is easy to manage. The first tempo arrives at an awkward moment (the week mileage bounces back, the day before a 9-mile long run), week 5 is steeper than the rest of the build, and there are no short, fast repeats. None of them changes the verdict.

Structure
Does the plan build you up smartly?
Gently at first, then one layer at a time. Five weeks of base, a nine-week build, a taper week and race week, each with a clear job. Harder sessions come in order (fartlek, then tempo, then goal pace), so nothing new arrives on legs that haven't met something like it. That shift in emphasis, from easy base to tempo Fridays to goal pace, tends to work better than training that never changes.

Prevention
Does the plan protect you from injury?
This build is kind to your legs. About 88% of the running is easy, all 9 harder sessions start with easy running (a full mile before each goal-pace run), and Saturday's long run stays easy after a harder Friday. The one exception is the peak week's dress-rehearsal weekend, where a Friday goal-pace run leads into a Saturday long run with goal pace in the middle. Weekly mileage climbs from about 9 miles to a peak of 21.5, mostly in small steps. Lighter weeks in weeks 4, 8, 12 and 15 ease the load before the next block asks for more. Expect them to feel almost too easy. Week 5 is the steepest step in the build, from 7.5 miles to 13 straight off the first cutback, with the first 6.5-mile long run. Your heart and lungs tend to handle that jump before tendons and bone catch up, so feeling ready isn't proof your legs are: run it slower than feels needed and walk a minute whenever you like. The first tempo, the week after the second cutback, lands as mileage bounces back and the day before a 9-mile long run. Treat it as an introduction and stay on the comfortable side of comfortably hard. The next two tempo Fridays are where you find the real effort.

Flexibility
What happens when you miss a day?
The plan ranks its sessions, so you know what to protect. Saturday's long run and the week's harder session come first, the easy runs next, and strength after that. Miss an easy run and just carry on. The miles don't need paying back on Saturday. Miss the harder session and either move it to the next easy-run day, with easy running or rest around it, or let it go, but don't run it the morning of a long run. Miss a long run and run it the next day if you can, a little shorter if you need to, then pick the week up as written. If a lingering ache shows up, easing off for about a week (less running, not a full stop) is a sensible precaution. Once it settles, tempo and goal pace are the first sessions to bring back.

Readiness
Will the plan deliver race-day fitness?
Race day gets a full rehearsal before you ever reach it. The peak week's Saturday is the dress rehearsal: 11 miles with 3 at goal pace in the middle, the day after a shorter goal-pace run. The discipline lives in the first 4 easy miles. Run them gently, because a quick opener is what turns the goal-pace block into a fight. By race morning you'll have met goal pace six times, with the blocks growing through the build, so the effort is familiar long before the start line. After the peak, the running eases off for two weeks, and race week holds just two short runs: Thursday's brief goal-pace touch and Friday's 15-minute shake-out. The race will be about 2 miles longer than your longest run, which is normal for a half.

Variety
Are the workouts varied enough?
Range is a real strength here, and each new kind of run gets its own introduction. Across the plan you'll run easy runs with strides, long runs, a fartlek, tempo runs, goal-pace runs, a long run with goal pace inside it and a shake-out. Each of the 9 harder sessions spells out its warm-up, main work and cool-down, from the fartlek's 30-second surges to the goal-pace blocks, and each explains why you're doing it. The one gap is short, fast repeats near the hardest pace you can hold for a few minutes. The strides cover a little of it, with regular practice at quick, relaxed running.

Welcome to the plan. Not long ago you were not someone training for a half marathon, and now you are. If the early days feel almost too easy, you are doing them right, because nothing here is meant to test you yet. You are not behind, and you are not late. You are exactly where someone with this goal on the horizon ought to be, with 15 weeks to go.
M 1.5mi Easy Run
1.5 miles at conversation pace, which means full sentences without strain. This is the first run of the plan. End feeling like another mile was on the table. The plan asks more of you later. Today's job is just to lace up.
Tu Strength Training
W 1.5mi Easy Run
1.5 miles easy, the same effort as Monday. Most runners on a beginner plan want to push the pace early because the distances feel small. The cost shows up a couple of weeks later as fatigue. Run slower than feels necessary.
Th Strength Training
F 1.5mi Easy Run
1.5 miles at conversation pace. A few runs in, your body is learning the rhythm of running on a schedule. Tomorrow is 4 miles, the biggest run of the week. Today is about saving something for that.
Sa 4mi Easy Run
4 miles easy. Run by feel from the first step: a pace where you could keep talking even at the end. Most runners take their longer runs too fast and finish in survival mode. This one shouldn't. Aim to end with another mile or two on the table. Today teaches the legs what easy looks like across a longer distance. How you run it shapes how the longer Saturdays go.
Su Rest
What this week is really asking of you is the small, ordinary act of lacing up and going outside on the days the calendar says to. Nothing dramatic is going to happen. No one is going to notice. That is the whole secret of half marathon training. The people who get to the start line healthy are the ones who kept showing up during these early weeks, when there was nothing to prove.
M 1.5mi Easy Run
1.5 miles easy. Keep it conversational. If your breathing tightens, slow until it doesn't. At this stage the body rewards showing up more than it rewards effort. The week opens gently, and the Saturday run grows by half a mile.
Tu Strength Training
W 1.5mi Easy Run
1.5 miles easy. Notice any sore spots from yesterday's strength session. If you find some, dial today softer. The aim is to arrive at Saturday's 4.5 miles with fresh legs.
Th Strength Training
F 1.5mi Easy Run
Three weekday runs feeding into Saturday's longer effort is the rhythm of the plan. The pace today should feel like running you'd do without thinking about it.
Sa 4.5mi Easy Run
4.5 miles easy, half a mile more than last Saturday. Keep it conversational the whole way. The first 2 miles will feel easier than the last 2. That's normal at this stage. The only fix is patience with the pace.

Plan Strengths
- Weeks 1 through 7 are easy running and strides only, so the harder work lands on a real base.
- Harder sessions arrive one kind at a time: one fartlek, three tempo Fridays, then goal pace.
- Lighter weeks every few weeks keep the build steady and give your legs a regular break from the load.
- Goal pace is rehearsed often enough to feel familiar, including inside the peak long run.
- Strides from week 3 and two strength sessions a week through week 15, on days away from the harder running.
- A taper week and a race week of just 2 short runs bring the running down while goal pace stays in the mix.
Weaknesses & Gaps
- The first tempo arrives the week mileage bounces back from a cutback, the day before a 9-mile long run.
- Week 5 is the steepest step in the build, with the first 6.5-mile long run straight off a cutback.
- No short, fast intervals: the harder work is fartlek, tempo and goal pace only.
What's missing
Nowhere in these 16 weeks will you run short, fast repeats, efforts of a minute to a few minutes near the hardest pace you can hold that long. For a first half they're optional, and skipping them costs little. To get a taste of what they offer inside the plan as written, give the fartlek's quick surges real intent and run every stride the full 100 meters, quick and relaxed, never a sprint. If this race goes well and you aim faster next time, short repeats are the piece to add then. There's also no tune-up race on the calendar, and you can reasonably skip one. A tune-up's main value is probably pacing practice, and the goal-pace runs already give you that.
What the science supports
Shifting training emphasis beats unchanging training
Sixteen weeks run in four phases. Base, weeks 1 to 5, is all easy running. Build, weeks 6 to 14, adds harder work in layers: a fartlek, loose bursts of faster running, in week 8, Friday tempo runs at a comfortably hard effort in weeks 9 to 11, then goal pace from week 12. Cutback weeks, lighter weeks that ease the load, land in weeks 4, 8 and 12 before the taper and race week. Changing the emphasis like this tends to beat a flat plan, whatever the model.

The body adapts on a staggered clock
Weekly mileage climbs from about 9 miles to a 21.5-mile peak in week 13, mostly in small steps, with lighter weeks at weeks 4, 8 and 12. Weeks 1 to 7 hold only easy running and strides before any harder work begins. Fitness tends to arrive within a few weeks, while tendons and bone take longer to catch up. That is why the mileage here goes up gradually even when you feel ready for more.
Longer long runs go with faster marathons
The Saturday long run climbs from 4 miles in week 1 to a peak of 11 miles in week 13, stepping back in each cutback week. For a runner aiming at 2:30, the 9 to 11 mile Saturdays run well past 90 minutes. Early evidence links longer long runs with faster marathons, though no study has tested whether shorter, faster sessions could do the same job. That finding comes mostly from marathon training and counts for less at the half marathon distance.
Doherty et al. 2020; Fokkema et al. 2020; Toresdahl et al. 2022
A real taper sharpens you for race day
The taper, the planned wind-down before race day, takes week 15. The Saturday long run falls from 11 miles to 8 and Monday shrinks from 4 miles to 2, while Wednesday keeps a 2-mile block at goal pace so the race speed stays familiar. Race week holds just a 3-mile run with 1.5 miles at goal pace and a 15-minute shake-out. Cutting running by 40 to 60 percent in the final week or two while keeping some speed improves race performance compared with not tapering.
Threshold or race pace: neither proven better
Tempo running comes first, on Fridays in weeks 9 to 11, at a comfortably hard effort quicker than goal pace. Goal pace takes over from week 12, including 3 miles inside the 11-mile peak long run. Tempo running and race-pace running are different kinds of training. For recreational runners either is a reasonable choice, and no study shows one beats the other, so the plan gives you some of each.
