Plan at a Glance
A sub-22 5K asks for two things at once: the speed to sit on goal pace, and enough endurance that goal pace still feels like goal pace in the third mile. This plan gives each its own day. It's built for runners already covering about 32 miles a week who can run 6 days, and the week settles into a shape you'll know by heart. Monday is speed. Wednesday is threshold, a hard but steady effort around half-marathon pace. Saturday is the long run. Everything else is easy, Friday is a slower recovery run that guards Saturday, and Sunday holds a strength session.
The base weeks build the habit of running most days, with strides and then hills on Monday and a short threshold run joining Wednesday. From there, Monday turns to reps at 5K pace that stretch from 400 m to 1000 m, so you practice the exact speed of the race in pieces you can hold. Wednesday's threshold grows from 2 miles to 4, then splits into cruise intervals, longer repeats with short jogs between. The long run climbs from 8 miles to 12.5. Lighter weeks arrive every few weeks, and each keeps a short threshold run so the effort stays familiar.
Most of your running here is easy, and that easy running builds the endurance that keeps goal pace feeling like goal pace late in the race. The two hard days pay off best when the days around them stay easy, so the run that decides your week is Tuesday's, the easy one between Monday's reps and Wednesday's threshold. Keep it at the pace you can talk at, even when the legs feel quick. The biggest week comes a few weeks out. Then the last stretch trims the running, keeps short reps at goal pace, and finishes with a short tune-up of 4 × 200 m, a shake-out the day before, and the race.
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
If you're close to sub-22, the tempting answer is to run fast more often. This plan answers with more easy running instead. It asks for 6 days, most of them easy, and a long run of 12.5 miles for a race of 3.1. That extra easy volume is the reason to choose the 6-day version: it puts a deeper base under the two hard days and allows a long run many 5K plans never reach. Monday trains goal pace in reps that grow longer through the build, Wednesday trains threshold, and a cutback every fourth week gives the legs some relief. Then race week asks for less running than a single one of those long runs.
The gaps are small. The step out of the first cutback is the steepest of the plan, the biggest week runs a touch past what the goal calls for, and the hard days come in only a few kinds. None of that changes the recommendation. The plan works if the Tuesday run stays easy when your legs feel quick, and if it does, you'll go into race week with goal pace practiced dozens of times over.

Structure
Does the plan build you up smartly?
In five clear stages, each with its own job. Base, build, sharpen, taper and race week each change what the week is for rather than just adding miles. Monday moves from strides and hills to 5K-pace reps while Wednesday's threshold run grows into cruise intervals, so the hard work shifts as the race gets closer. The long run builds just as patiently, from 8 miles to 12.5, and peaks three weeks before race week so you're not carrying it into the taper.
-
Prevention
Does the plan protect you from injury?
The safeguards are built into the shape of the week. Tuesday's easy run keeps Monday's reps and Wednesday's threshold apart, each of those sessions starts with 1.5 or 2 easy miles, and Friday's recovery run sits in front of each long run. Higher mileage built up gradually tends to go with fewer injuries, not more, and this plan builds it that way. Weeks 4, 8 and 11 pull the running back to between 29.5 and 34 miles before race week cuts it further. The one week to watch is week 5. Coming out of the first cutback, the running jumps from 29.5 miles to a new high of 41.5, and the first 5K-pace reps arrive the same Monday. A weekly jump that large tends to be a warning sign, which makes this the week to be most conservative. If a sore spot appears, give it a few easy days before the next Monday session comes round rather than pushing through it.

Flexibility
What happens when you miss a day?
The plan makes the priorities easy to read. Monday's speed session, Wednesday's threshold run and Saturday's long run carry the plan. Friday's recovery run comes next, and when a day has to go, start with Tuesday's or Thursday's easy run. If you miss Monday, don't squeeze it into Tuesday, because that puts it right against Wednesday's threshold and gives you two hard days in a row. Let it go and pick up with Wednesday. If you lose a few days in a row, come back on easy running and rejoin the rhythm the next Monday rather than making up the miles. The cutback weeks give you a natural place to reset if life has knocked the build sideways.

Readiness
Will the plan deliver race-day fitness?
Squarely on target for a 5K. Race-specific work runs from the second week all the way to race day, and it grows as the race gets closer. The 5K-pace reps lengthen from 400 m to 800 m to 1000 m, which keeps the work squarely on the effort the race asks for. In a coach's view, the threshold work underneath them is what lets goal pace hold together in the last mile. The 12.5-mile long run gives a 5K plenty of aerobic support. Then a proper taper cuts the running over the final weeks while keeping short reps at goal pace, and a well-built taper like this helps runners race better than training straight through. Race week brings a 4 × 200 m tune-up on Thursday, a shake-out on Saturday and the race on Sunday.

Variety
Are the workouts varied enough?
Expect a different rep on most Mondays. Across the plan you'll run easy runs, long runs, threshold runs, hill repeats, reps at 5K pace, cruise intervals, a race-week tune-up and the race itself, and the reps come as 400s, 800s, 1000s, 1.5-mile and 2-mile cruise intervals, and two sets of hills. Strides on an easy day most weeks keep quick running familiar at almost no cost. The narrow spot is the hard days themselves, which come in only four kinds. There's no fartlek (faster bursts dropped into an easy run) and no progression run.
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.
11 weeks stand between you and the race, and none of them asks you to prove anything yet. The early days are for learning what easy feels like in your legs right now. Run slower than your pride wants and let the days stack up. Running most days of the week takes some getting used to, even for experienced runners. Sleep well, keep the effort low, and let the routine form before the harder days arrive.
M 5.5mi Easy Run with 4×100m Strides
5 miles easy, then 4 × 100 m strides with an easy 100 m jog after each. The opening run of the plan asks for nothing beyond easy running and a few quick strides at the end. Strides are short pickups, quicker than 5K pace yet relaxed, and never a sprint. They keep fast running familiar while the weeks are built mostly on easy distance. Ease off over the closing steps of each one.
Tu 5mi Easy Run
5 miles at conversational effort. You should be able to talk in full sentences without breaking the rhythm. Hold this whether the legs feel light or heavy. Miles like these are where your aerobic base builds, one easy run at a time.
W 6mi Easy Run
6 miles easy, a little longer than the runs either side of it. Keep it aerobic. This is where weekly volume earns its keep. Most runners find the extra distance passes without notice, and it adds up without ever feeling like work.
Th 5mi Easy Run
The day after a slightly longer effort tends to feel a little flat. That's the volume settling in, not a problem. The harder days only pay off when days like this stay gentle.
F 3mi Recovery Run
Slower than easy by a margin you should feel, not measure. Tomorrow's long run is the workout this run protects. Recovery runs keep the blood moving while the body absorbs the work around them.
Sa 8mi Long Run
8 miles at long-run effort, relaxed enough to talk the whole way. The first long run of the plan tends to feel longer than its distance. Find a flat or rolling route and stay patient through the first 3 miles. The part that counts comes in miles 5 through 8, when the legs are tired and holding back starts to cost something. That cost is the point.
Su Strength Training
The week has a new shape now, with a harder day sitting in the middle of the easy running. Most runners notice the easy days feel different once there is something to protect. That is how the rhythm of the plan starts to take hold. Keep the easier days gentle even when the legs feel good, because the harder day only pays off when the rest stay easy. Showing up matters more than any single run.
M 5.5mi Easy Run with 4×100m Strides
5 miles easy, then 4 × 100 m strides. Monday stays easy again, and the strides are its only touch of speed. The threshold run arrives on Wednesday, so leave today feeling fresher than you started. Run each stride tall and let the speed come from quick feet rather than force.
Tu 5.5mi Easy Run
5.5 miles easy. A plain day between the strides and Wednesday's threshold run. Keep the pace loose enough to chat, and save any extra energy for tomorrow, when it has a job to do.
W 5mi Threshold Run with 2mi @ Threshold
Warm up 1.5 miles easy, then run 2 miles at threshold and cool down 1.5 miles. Threshold here means about half-marathon pace, 7:42/mile, hard enough to need focus but well short of racing. The opening threshold run is short on purpose, so you can learn the effort before the blocks get longer. Race pace gets the headlines, but this steady effort is a different kind of work with its own day. If your breathing turns ragged, you are running too fast for this day.
Th 5.5mi Easy Run
5.5 miles easy. The legs often start stiff the day after a threshold run. Let that ease out on its own before you think about pace, and keep the whole run conversational.
F 4mi Recovery Run
Pace is a clear step below easy. The legs should feel like they've turned over, not like they've worked. The point is circulation, not fitness. The fitness is already in there, settling.
Sa 9mi Long Run
9 miles at long-run effort. The longest run yet, and the step up is small on purpose. The body answers to consistent doses, not heroic ones. Start slower than feels natural, since the effort creeps up on its own. Hold the pace steady through the back third, where it usually wants to drift up. Most runners feel the extra distance only in the closing miles.

Plan Strengths
- Hard days kept apart, with easy running and a Friday recovery run between them.
- 5K-pace reps that lengthen from 400 m to 1000 m, well matched to the speed of the race.
- A threshold strand that grows from 2 miles to 4 and then into cruise intervals.
- A cutback every fourth week, so the legs get a lighter week of relief before each new block.
- Short reps at goal pace stay in through the taper, and race week brings a 4 × 200 m tune-up and a shake-out the day before.
Weaknesses & Gaps
- Coming out of the first cutback, the running jumps to a new high in the same week the first 5K-pace reps arrive.
- The hard days come in only four kinds, with no fartlek or progression run.
- The plan leans a little further toward easy running than it needs to, so the hard running is a slightly smaller slice than a 5K plan could carry.
- The biggest week, around 46 miles, runs slightly past what the goal calls for.
What's missing
Plan around three gaps, each easy to patch. First, an easier way back from the first cutback, where the first 5K-pace reps arrive in the same week the mileage climbs to a new high. You can soften it by taking a mile off that week's Tuesday and Thursday easy runs and running the 400s at goal pace, not a step faster. Second, the looser kinds of hard running, since there's no fartlek or progression run. If you want a taste of it, swap Thursday's strides for 6 relaxed surges of about 30 seconds now and then, no harder than the strides they replace, so the day after threshold still stays easy. Third, a lighter version of the biggest weeks. If around 46 miles is well beyond anything you've run before, trim a mile or two from the Tuesday and Thursday easy runs in those weeks. They're the lowest-priority days, and the long run and both hard sessions stay whole.
What the science supports
Shifting training emphasis beats unchanging training
The plan moves through five phases: Base Building in weeks 1 to 3, Build in weeks 4 to 8, Sharpen in weeks 9 and 10, a taper week, then race week. Monday's work shifts from strides and hills to 5K-pace reps that grow from 400 m to 1000 m, while Wednesday's threshold run grows from 2 miles to 4. Shifting the emphasis of training over time like this tends to beat holding it the same, though the gain in trials was small.

Keep easy days easy, hard days hard
The plan asks for six days of running, but in most weeks only two carry hard work: Monday's reps or hills and Wednesday's threshold run. The rest stay easy or at recovery effort, where you can speak in full sentences, and no two hard days ever sit back to back. About 88 percent of the running is easy. For most trained distance runners, that clean split may work better than weeks of medium-effort running, never easy and never truly hard.

Sharp running-load jumps raise injury risk
Big jumps in running tend to raise injury risk. The clearest case is a single run that goes well past your longest of the past month, and weekly jumps above about 30% are a warning sign too. Weekly mileage here builds from 32.5 to a peak of 46.4 in week 9, and no run in the plan goes well past the longest one before it. Outside the climbs back from cutbacks, each week rises in modest steps.
Consistent mileage is linked to fewer injuries
Every week before race week runs between 29.5 and 46.4 miles, spread over 6 days of running. Runners whose weekly mileage stays higher and consistent tend to get hurt less often, not more. That finding comes from watching runners rather than from trials, and not every study agrees, so read it as a pattern rather than a promise.
A real taper sharpens you for race day
The taper runs over the last 2 weeks. Week 11 trims running to 34 miles while 4 × 800 m at 5K pace and a 2-mile threshold run stay in, and race week drops to 12.2 miles before the race, a cut of about 74 percent from the 46.4-mile peak. Thursday's 4 × 200 m at goal pace keeps speed in the legs. A taper of up to 3 weeks that cuts volume and keeps some intensity, like this one, improves race performance compared with not tapering.
