Plan at a Glance
A sub-2 half marathon asks one thing of you for a long time. Hold a pace that feels manageable at mile 3 and much less manageable at mile 11. This plan spends nearly all its hard work on that one pace. Every quality session runs at your goal pace, and it teaches the pace in stages. On Wednesdays you meet it in pieces, half-mile and then three-quarter-mile repeats with a jog between, until late in the build those pieces join into one continuous run. On Fridays you hold it without a break, in a tempo run that grows a little each time. In the biggest week, you run 6 unbroken miles at goal pace midweek, and your longest Sunday run carries 3 more goal-pace miles in its middle. By race morning, the pace is no stranger. Your legs know where it sits.
The base weeks have one aim: to make four runs a week feel like the floor of your schedule, not the ceiling. After a short easy start, goal-pace work arrives all at once. The repeats, the tempo and your first strides begin in the same week, as your total running climbs. On rested legs, those first repeats will feel almost too easy. Run them at goal pace anyway, and no faster. If you think of speed work as a track session that leaves you wrecked, these won't feel like much, and that's the plan working. A lighter week follows each block of harder ones so your legs can absorb the work. In the last stretch the miles come down while goal pace stays, in shorter doses, so the rhythm doesn't fade.
Come in with about 16 miles a week already in your legs, spread over four days. Most weeks, runs fall on Monday, Wednesday, Friday and Sunday, with strength on Tuesday and Thursday and Saturday left free. The longest run reaches 13 miles, so on race day the distance isn't the question. The pace is, and that's what the whole plan practices.

Our Review
If you've finished a half past two hours and half expect the pace to fade late, this plan aims straight at that problem. Its strength is focus. Almost every hard mile is at goal pace: Wednesday's session grows from repeats into continuous running, ending in 6 unbroken goal-pace miles in the peak week, while Friday's tempo lengthens alongside it. The phases are clear, a lighter week follows each block, most of the running stays easy, and hard days never fall back to back. Sunday's long run tops out at 13 miles with a 3-mile goal-pace block in its middle, and once weekly running peaks at 36 miles, the taper trims it while keeping a short goal-pace run in every remaining week. The thing to plan around is weeks 3 and 6, when Wednesday's session runs well past anything you've run in the month before. Recommended, with those two weeks run gently.

Structure
Does the plan build you up smartly?
Yes, though the whole build is one block aimed at the race. From the first goal-pace sessions onward, every hard day is race-pace work. The opening weeks are easy running only, so goal pace arrives without an earlier stretch of hill running or shorter, quicker reps behind it. Every hard session spells out its warm-up, its work and its cool-down, and says what it's for, so you always know what a day is asking of you.

Prevention
Does the plan protect you from injury?
Well in most weeks, less so in the 2 where the load climbs too fast. Most of the weekly running is easy, and lighter weeks in weeks 4, 8 and 12 give each stretch of the build some relief. Wednesday's repeats sit between 1.5 easy miles on each side, and Friday's tempo gets at least a mile at each end. Wednesday and Friday are the hard days, with a strength day between them, so no hard run follows another. Week 3 starts both goal-pace sessions in a week that's also bigger than the one before, and its Wednesday runs 8.2 miles, well past anything yet. Week 6 does it again, with Wednesday's repeats coming to about 12 miles in the same week as the first real long run. Big jumps tend to raise injury risk, most clearly when a single run goes well past your longest of the past month. In those two weeks, keep the easy runs truly easy, and treat a new ache as a reason to ease off before the next run, not after it.

Flexibility
What happens when you miss a day?
The plan makes it clear what to protect. Wednesday's session, Friday's tempo and the Sunday run carry the plan. Strength days are the first to let go, then the easy runs: the Mondays, and the easy Wednesdays and Fridays of the lighter weeks. If you miss a Wednesday session, don't slide it to Thursday or Saturday, where it would crowd Friday's tempo or the long run. Let it go, run Friday as written, and keep Sunday. If a whole week goes, rejoin at the week the calendar shows and leave that week's Wednesday and Friday behind. When an easy day gets squeezed, run what fits and let the rest go. A shorter easy run still does its job. Through the build, Saturday stays free, which gives you a spare slot to move an easy run into.

Readiness
Will the plan deliver race-day fitness?
By race day, both halves of the problem have been rehearsed. The long run builds to 13 miles three weeks out, a tenth of a mile short of the race itself, so on race day the distance isn't the question. The only question left is whether the pace holds, and that's what the build has rehearsed: by the peak week you're running 6 unbroken goal-pace miles midweek and 3 more inside the long run. Weekly running peaks at 36 miles, a level that suits a half. Then the taper cuts the miles while keeping a short goal-pace run each week, right through race-week Monday. Coming down to 26 and then 21 miles, with that pace still in your legs, tends to leave you faster on race day than training straight through.
-
Variety
Are the workouts varied enough?
Wide-ranging, so the weeks never blur together. You'll run easy days, strides, long runs, half-mile and three-quarter-mile repeats in four different counts, continuous tempos, a long run with goal pace in its middle, and the race itself. Every hard session runs at goal pace, about a third of a typical build week, which keeps the whole build pointed at one rhythm. Threshold work (the effort you could race for about an hour) is a different kind of training, and neither has been shown to beat race-pace work. An occasional threshold session is an option to widen the mix, not a missing piece.

15 weeks stand between you and race day, and this one is in front of you now. The goal you signed up for is real. The months between now and the finish line are going to do a lot of the talking. For now there is nothing to prove. Let the early runs feel almost too easy, and pay attention to how your week shapes itself around the schedule. The habit of showing up to the week the way this plan asks is the foundation everything else gets stacked onto.
M 3.5mi Easy Run
3.5 miles at conversational pace. This is the first run of the plan. The kind of effort where you could narrate the whole run out loud without running out of breath. These early easy runs are the foundation. Everything harder rests on them.
Tu Strength Training
W 3.5mi Easy Run
Same 3.5 miles, second time through. If yesterday you ran by feel, today try to repeat the feel without checking. Easy effort gets steadier the second time you visit it in a week. That's the point of repeating the same distance early.
Th Strength Training
F 3.5mi Easy Run
Third easy run, same 3.5 miles. By now the route may feel routine, and that's exactly the texture you want. These early runs are about installing the pattern, not testing it. Soft breath. Slow shoulders.
Sa Rest
Su 5mi Easy Run
First Sunday run of the plan: 5 miles, all easy. This isn't a long run yet. It's the longest of your easies, and the slot the long run will eventually live in. Run it slightly slower than you ran the weekday 3.5s. The longer the run, the less the pace should ask of you.
The shape of the week is settling into your body now, and your legs are starting to learn what easy actually means inside this kind of cadence. The opening stretch of a long plan is mostly about teaching yourself how to show up across the whole week without making any single day a hero. None of it has to feel impressive. The point is whether you're still here, still moving, when something harder gets asked of you later on.
M 4mi Easy Run
4 miles easy, a small step up. The distance rises slowly here because nothing about this week needs to feel like a stretch. If anything pushes past conversational, walk it back to where it was Sunday.
Tu Strength Training
W 4mi Easy Run
4 again on a Wednesday. The legs are still learning what '4 runs a week' actually feels like, and the rest day in between is doing real work. Don't chase yesterday's easy strength session into this run. Keep it separate.
Th Strength Training
F 4mi Easy Run
Third 4 of the week. The pattern from week one carries over: three short midweek runs, longer on Sunday. Hold the pace where conversation flows. The body learns easy by repeating easy, not by running it faster on day three.
Sa Rest
Su 5.5mi Easy Run
5.5 miles, all easy. Treat the last mile the same way you treated the first: shoulders loose, breath even, footstrike unhurried. If the second half asks you to push, slow down enough that it stops asking.

Plan Strengths
- Every hard session teaches the same pace, and Wednesday's work grows from repeats into continuous running, ending in 6 unbroken goal-pace miles in the peak week.
- The long run reaches 13 miles three weeks before the race, so the distance holds no surprises on race day.
- The taper cuts mileage while keeping a short goal-pace run each week, so the race rhythm never drops out of the week.
- About three quarters of the running is easy, and a strength day on Thursday keeps the two hard runs apart.
- A lighter week follows each block of the build, so the tiredness from one stretch never piles straight into the next.
Weaknesses & Gaps
- Week 3 introduces both goal-pace sessions at once, in a week that's also bigger than the one before. It's the sharpest jump in the plan.
- A second jump comes in week 6, when Wednesday's repeats total about 12 miles in the same week as the first real long run.
- There are only two kinds of hard session, both at goal pace. Nothing in the plan is faster than goal pace except strides.
What's missing
Goal-pace work arrives without a gentle way in. Both the repeats and the tempo start in week 3, in a week that's already bigger. You can soften that yourself: run the Wednesday repeats as written and make that Friday an easy run with strides, so only one new session arrives at a time and the tempo starts in week 5 instead. It also leaves out any running faster than goal pace, apart from strides. If the build feels manageable after the second cutback, run the week 9 and week 10 Wednesday repeats at threshold effort (the pace you could hold for about an hour) instead of goal pace, with a couple fewer repeats so the total stays about the same. Keep the Friday tempos and the long runs as written, since they're what teach you to hold the pace.
What the science supports
Fixed plans need built-in lighter weeks
Training that keeps piling up without relief tends to raise the risk of injury and illness. On a fixed plan, a scheduled lighter week is the simplest way to build that relief in. Here every fourth week drops back to between 14.5 and 21.5 miles, and the goal-pace sessions give way to easy running and strides before the next climb begins. How often to step back is coaching practice rather than a proven rule.
Explosive work can make you more efficient
Strides are short relaxed bursts of speed. Short explosive efforts like these can help runners use less energy at a given pace, though results are mixed and strides themselves have not been tested directly. In this plan, 4 strides of 100 meters follow an easy run in every week after the opening 2 weeks, cutbacks and taper included. They take a few minutes and keep fast running familiar on otherwise easy days.

Two strength sessions a week is enough
Most runners get the running benefit of strength work from about 2 sessions a week, on days that aren't back to back. The habit needs to hold for at least 6 to 12 weeks. This plan puts strength on Tuesday and Thursday for 15 weeks, then drops it for race week. Neither day carries a run, so strength work never crowds a goal-pace session or the long run.

A real taper sharpens you for race day
A taper, the lighter stretch before a race, of up to 3 weeks improves race performance compared with training straight through. This plan tapers over 2 weeks. The weekly miles step down from 36 to 26 and then 21, and the long run shortens to 10.5 miles and then 9. Each of those weeks still carries a short goal-pace run, so race pace stays familiar.
Keep easy days easy, hard days hard
Trained runners may improve more when easy days are truly easy and hard days are clearly hard than when every run sits at a middling effort. About 77 percent of this plan's running is easy. Through most of the build, this plan keeps its hard running to Wednesday and Friday, with a day between them. Monday and most Sundays ask for conversation pace, so the line between the two kinds of day stays clear.
