Plan at a Glance
You know the race. The first mile went to plan, maybe a little quick. Somewhere in the second, hard turned into too hard, and the last stretch was about hanging on rather than racing. Most runners read that as a speed problem. They go back to the track and run more 400s, which feel productive because you finish them gasping. This plan reads it the other way. What decides sub-22 is how long you can hold a hard effort, so that's what it trains first.
It starts with nothing harder than easy running, strides, a few 30-second fartlek bursts, and a long run on Saturday. Then Tuesday becomes threshold repeats, a mile or longer at the effort you could hold for about an hour, and Friday picks up a steady tempo just under it. Only once that floor is built does Tuesday turn to goal-pace intervals, while the Friday tempo keeps running underneath. The last stretch opens with the plan's longest goal-pace work, moves to shorter, quicker reps, and then cuts the running way back in the days before a Sunday race. Thursday is for strength, and Sunday is yours until race day.
Most of your miles stay at the pace you can talk at, which is what lets two quality days and a long run fit into a modest week. It's written for someone already logging about 28 miles a week, and the biggest week reaches only the mid 30s.
The plan turns on Fridays. Once the tempo grows longer and Tuesday's intervals are still in your legs, you'll feel good around the second mile and want to press toward threshold. Don't. A Friday that becomes a second Tuesday costs you Saturday's long run and the next Tuesday's reps. Holding back there is the same skill the race asks of you at mile 2.

Our Review
With 5 days and sub-22 in view, you need a clear idea behind the plan, and this strong one is well worth running. It builds the ability to hold a hard effort before it asks for goal pace, keeps the large majority of the running easy, and never puts two hard days back to back, so a modest week can carry a Tuesday session, a Friday tempo and a Saturday long run. The phases are distinct, the long run peaks four weeks before the race, and race week cuts deep while keeping a little goal-pace work in. Much of it comes down to Friday. Hold the tempo at tempo, even when Tuesday went well and the second mile feels easy, and the rest of the week works. Go in knowing two small things. New kinds of session tend to arrive in weeks that are also growing, so run each one a touch easy the first time. And the two opening fartleks set their bursts by feel alone, so those first hard days are yours to judge. If you already run about 28 miles a week over 5 days, this is the version to trust.

Structure
Does the plan build you up smartly?
The build comes in the order a 5K runner needs it, with each block handing the next a little more to work with. The four phases (Base, Threshold, Speed, Sharpen) are distinct, and each asks for something new: easy miles and strides, then threshold, then goal-pace intervals, then sharpening. Shifting the emphasis like this tends to beat holding one kind of training all the way through. Nearly every hard session is written out from warm-up to cool-down, and each one says what it's for.
-
Prevention
Does the plan protect you from injury?
Every week is laid out so the hard days never wear into each other. The large majority of your miles are easy, Tuesday's threshold repeats and Friday's tempo each open with 1.5 easy miles, and Wednesday's easy run and Thursday's strength day keep the two from ever touching. Keeping easy days easy and hard days clearly hard tends to help most runners improve, and this plan is built on it. Two mid-plan cutbacks trim the volume and keep a lighter version of the key session, so the build never runs long without relief. Week 5 holds the plan's biggest rise, from about 27 miles to 34, and the first of those cutbacks follows straight after it. The first goal-pace intervals and the first race-pace run also arrive in weeks that are growing, so new work and extra miles come together. If something starts to ache in one of those weeks, shorten the Monday and Wednesday easy runs until it settles instead of running through it.

Flexibility
What happens when you miss a day?
The week is easy to repair. Hard days never touch, Sunday is open, and the plan ranks its sessions: the Tuesday session and the Friday tempo first, the Saturday long run and stride days next, the easy runs last. If you lose a day, let an easy run go before anything else. If you miss Tuesday, run it Wednesday, and Thursday's strength day still sits between it and Friday. If the week gets away from you and only one of the two key sessions will fit, either is a fair choice. Once Tuesday turns to goal-pace intervals, though, the Friday tempo is what keeps the threshold work in place, which is a reason to keep it. In a cutback week, let a missed day stay missed. Those weeks are there to give your legs relief, not to be made up.

Readiness
Will the plan deliver race-day fitness?
This is a complete race build for a sub-22 5K. Peak mileage and the long run both fit a sub-22 5K, and race-like work runs through every week after the opening one: fartlek, then threshold repeats, then 800s, 1000s and 400s at goal pace. The taper cuts race week deep while keeping a short goal-pace session and strides, and a taper built that way improves race performance compared with not tapering. The biggest goal-pace session holds nearly twice the race distance at that pace, broken into repeats, which is how a 5K is usually rehearsed.

Variety
Are the workouts varied enough?
Amply, from 30-second fartlek bursts to 1.5-mile threshold reps. Eight kinds of run fill the calendar, from easy and long runs to fartlek, tempo, threshold, goal-pace intervals, a race-pace run and the race itself. The intervals come in many shapes, from mile repeats at threshold to 800s, 600s, 1000s and 400s at goal pace, and each piece names its effort (threshold, tempo, goal pace) tied to your own goal. Every hard session spells out its warm-up, work and cool-down and says what it's for. If most of your speed work so far has been 400s, the longer reps are the change you'll notice: they ask you to stay settled inside discomfort, which a short rep never does. Strides through the base weeks and a weekly strength day round it out, and the strength day in particular makes your running more efficient.

11 weeks to race day, and these opening days are mostly about getting the rhythm of training under you. You chose a faster 5K, and the first week toward it needs no dressing up. The running is modest and the speed work is light on purpose. Find your easy pace, sleep enough to back it up, and let the calendar do its slow work from here. Beginnings count for something even when they look ordinary.
M 5mi Easy Run
5 miles easy, at conversational pace. This is the opening run of the plan. You should finish feeling able to keep going for another 2 miles. Easy days stay easy, and that rule keeps the rest of the plan working. The habit starts with runs like this one.
Tu 5.7mi Easy Run with 6 x 100m Strides
Easy 5 miles, then six 100m strides on the flat after the run. Strides are smooth accelerations to about mile pace. They wake up quick leg turnover before the real speed work begins next week. The strides should feel quick and easy.
W 5mi Easy Run
Same effort as Monday. This is base building. Resist the temptation to push because the legs feel fresh. The point of this week is the aerobic base. The work compounds across weeks.
Th Strength Training
F 4mi Easy Run
Short and recoverable, leading into Saturday's long run. The legs should be loose and ready to roll on Saturday. If anything is sore, this is the day to take it slower than planned.
Sa 8mi Long Run
8 miles easy, at conversational pace. This is the first long run of the plan. You should be able to talk in full sentences the whole way. The aerobic base this run builds is the foundation the threshold and interval work will sit on top of. From here the long run climbs to 12 miles by week 8.
Su Rest
The early weeks of a build are mostly invisible work, and what gets laid down here is what everything later stands on. Nothing in this stretch is going to feel heroic, and that is the point. Show up for the easy days, hit the harder day with intent, and let the rest of the week stay simple. You have done enough training cycles to know that the ordinary weeks decide more than the dramatic ones do.
M 5mi Easy Run
5 miles easy, the same pattern as before. Keep it conversational the whole way. Within a couple of weeks you'll stop thinking about it. The repetition is the point of base running.
Tu 30-90 Fartlek
Warm up 0.5 mile, then short quick bursts with longer easy floats between, and cool down 0.5 mile. The shortest bursts are strides, quick and relaxed rather than sprinted. Hard means fast turnover, not strain. The easy is genuine jogging, not a tempo float. Speed-play mixes paces inside one run, teaching the body to change gears without stopping. The surges build speed while the rolling format keeps the stress manageable. Make the hard parts decisive and the easy parts genuinely easy. Surge with quick feet rather than strain, and ease off cleanly. The session was a success if the last surge felt as crisp as the first.
W 5mi Easy Run
The day after a fartlek often feels heavy in the first mile and clears by mile two. That's normal. Trust the pattern. The second mile tells the truth.
Th Strength Training
F 4.4mi Easy Run with 4 x 100m Strides
Easy 4 miles plus 4 strides at the end. A light touch of speed ahead of Saturday's long run. The strides should feel smooth. Same shape as Tuesday's strides, lower volume. Most of the base gets built on days like this one.
Sa 9mi Long Run
Long run, 9 miles. 1 mile more than the 8-mile long run before it. Comfortable through mile 7 and start to notice fatigue in the last 15 minutes. That's the right shape for this point in the plan.

Plan Strengths
- Speed waits its turn. Threshold repeats and a Friday tempo build the ability to hold a hard effort before goal-pace intervals arrive, which is what a runner who fades in the second mile needs most.
- Easy days stay easy. Wednesday's easy run and Thursday's strength day separate Tuesday's session from Friday's tempo, so two quality sessions a week fit on mileage that tops out in the mid 30s.
- The long run reaches 12 miles four weeks out, more aerobic support than the race distance suggests.
- The taper works. Race week cuts deep but keeps 4 × 400 at goal pace and strides, so the miles fall while some speed stays in.
Weaknesses & Gaps
- New kinds of session, the first goal-pace intervals and the first race-pace run, arrive in weeks that are also growing.
- Your first two hard days lean on your own judgment, since the opening fartleks set their bursts by feel alone, with no effort tied to your goal.
What's missing
One thing is easy to add yourself. When a new kind of session lands in a growing week, like the first goal-pace intervals or the first race-pace run, run it a touch conservatively. Keep the easy runs around it truly easy too. A pacing check is optional. If you want one, swap the Saturday run in the last cutback before race week for a local 5K or a solo time trial at goal effort. Run 2 easy miles before and after, and treat it as pacing practice rather than a fitness test, a chance to learn what goal pace feels like when you hold it.
What the science supports
Shifting training emphasis beats unchanging training
The plan moves through four distinct phases: a three-week base with neuromuscular prep, a threshold-focused block pushing sustained hardness, a VO2 max block sharpening speed, and a sharpening phase leading into a six-day taper. The shifts are visible in week notes and workout structure. Shifting the emphasis of training like this tends to beat holding it the same throughout, though the measured gain is small.
Filipas et al. 2021; Bradbury et al. 2020; Sandbakk et al. 2025
Explosive work can make you more efficient
Strides are short, relaxed bursts of quick running. Here 3 easy runs in the base weeks end with 4 to 6 strides of 100 m, and 4 more close the shake-out 2 days before the race. Jump and sprint training can make a given pace cost less energy, though results are mixed and strides themselves have not been tested. Count them as cheap practice at running fast, not a proven gain.
Paavolainen et al. 1999; Turner et al. 2003; Eihara et al. 2022
Threshold or race pace: neither proven better
For recreational runners, threshold work and race-pace work are different kinds of training, and either is a reasonable way to prepare, since no study shows one beats the other. This plan gives you a block of each. Tuesday is a threshold day for three weeks, at the effort you could hold for about an hour, before 5K-pace intervals take over in week 7. The Friday tempos carry on alongside them through week 8.
Smyth & Muniz-Pumares 2020; Jones et al. 2021; Vickers & Vertosick 2016
Strength training makes running more efficient
Once a week, on Thursday, a day off from running, the plan prescribes strength training through week 11. In trained runners, structured strength work improves running economy, the energy cost of a given pace. That gain is separate from VO2 max work. For a runner chasing sub-22, that means getting more out of each mile without adding any.
Blagrove et al. 2018; Balsalobre-Fernández et al. 2016; Šuc et al. 2022
A real taper sharpens you for race day
Week 12 drops one running day and cuts volume to 12.1 miles, race included, while preserving intensity touches: 4 × 400 m at 5K pace on Monday and strides on Friday's shake-out. Those keep the legs primed without adding fatigue. A taper that cuts volume while keeping intensity improves race performance compared with not tapering.
