Plan at a Glance
You already run most days. This plan keeps it that way, and asks for less hard running than you might expect: two focused sessions a week, with everything else easy. The extra days don't go into more speed. They go into easy miles, because easy miles are what let the two hard days land.
Monday is repeats at goal pace. They start as short 400s, stretch to 800s, and reach 5 × 1000 m in the biggest week, which is the whole race distance at the pace you want to run it, cut into pieces you can hold. Wednesday is a continuous run at threshold effort, comfortably hard, the pace you could race for about an hour. It grows to 4 miles, longer than the race itself, and it is a different kind of work from the goal-pace repeats. Friday finishes with strides. Saturday is a long run that stays easy and stays modest. Sunday is a short strength session and no running.
The mileage opens right where you are, around 34 miles a week, and climbs gently to about 40. Then it comes down, and the repeats come down with it: fewer of them, at the same goal pace, on legs fresh enough that the pace starts to feel quick. The day that decides how it goes is the Tuesday after 5 × 1000 m. Your legs will be flat, the run will say 5.5 miles easy, and you'll want to run it at a pace that looks respectable on your watch. Run it slow enough to talk instead, so Wednesday's threshold can be the run it's meant to be.
Below is Buena Vida's full review of this plan. We hold every plan to our detailed, 30-point benchmark, with each measure pulled from peer-reviewed sports-science research and proven coaching best practices.

Our Review
If you've been circling 22 minutes for a while, it's natural to think the answer is more speed, and that six running days should mean three or four hard ones. This plan disagrees, and makes a strong case. It spends your six days on two hard sessions, goal-pace repeats on Monday and a threshold run on Wednesday, kept a full day apart, and fills the rest with easy running, about 85% of the volume. Those easy miles are the base of the week, and they are what let the hard days be truly hard. The mileage starts at what you already run and builds gently to about 40 miles a week. The long run tops out at 11 miles and never pretends to be marathon training. Monday's repeats and Wednesday's threshold run both open with an easy mile and explain their purpose in a sentence or two.
The one gap is small. The hard work comes in only two flavors, with no hills or fartlek to change its shape, and that doesn't undermine the build. If you're already running six days at around 34 miles and want the line under 22, this is a confident pick. Expect it to leave you less tired than you think a sub-22 block should. A Tuesday that feels too easy after Monday's repeats is the plan working, not the plan falling short.

Structure
Does the plan build you up smartly?
The shape is patient, and it suits a block this short. A 4-week build comes first, then a taper week, then race week. Planned shifts in emphasis like these tend to beat holding one load the whole way. The two hard strands grow in steps (Monday repeats go from 400s to 800s to 1000s, Wednesday threshold from 2 to 3 to 4 miles), and in week 3 the threshold run holds steady while the repeats lengthen. Every hard session is written out in full, from warm-up to cool-down, with a note on what it's for.
-
Prevention
Does the plan protect you from injury?
This is a careful build, with guardrails in all the usual places. Weekly mileage rises in small steps (34.5, 35.5, 38, then 39.9 miles) and none of them jumps. That matters, because sudden jumps in running load tend to raise injury risk. About 85% of the running is easy, so you come to each hard day recovered. The two hard sessions never fall on consecutive days, since an easy day always sits between them. Each new format (threshold in week 1, repeats in week 2) arrives without a big jump in mileage alongside it. All 10 hard sessions open with a warm-up, and strides and a weekly strength session stay on the calendar through the build and the taper.
-
Flexibility
What happens when you miss a day?
Most of the week can bend. Three days carry the build: Monday's repeats, Wednesday's threshold run, and Saturday's long run. Tuesday, Thursday and Friday are easy mileage, and they give way first. If you lose a Monday, move the repeats to Tuesday and run Wednesday easy, so two hard days never land back to back. If you lose a few days to illness, don't make up the missed hard sessions. Pick up the schedule where it is. In a block this short there's no room to catch up, and no need to. If one build week comes up light, let it go and keep the taper as written. The plan never writes out a missed-day rule, so anything past this is your call.

Readiness
Will the plan deliver race-day fitness?
The plan answers every question a 5K at this level asks: volume, race-pace work, and taper. A peak of about 40 miles a week and an 11-mile long run sit comfortably within what a 5K at this level calls for. The long run peaks 2 weeks before race week, well clear of the start. Race-specific work is in every week and grows toward the race: the repeats build to 5 × 1000 m at goal pace in the biggest week, a session that adds up to the full race distance. The threshold runs teach you to hold a hard effort for longer than the race lasts. Then a structured taper cuts the volume while a short 4 × 400 m session keeps goal pace familiar. Tapers like this tend to help runners race better than training straight through.
-
Variety
Are the workouts varied enough?
There's real range here, most of it outside the hard days. The run types cover the ground a 5K needs: easy runs, a weekly long run, threshold runs, goal-pace intervals, strides, a shake-out, and the race. Within the intervals there's real progression in format (8 × 400 m, 6 × 800 m, 5 × 1000 m, then shorter sets of 4 × 800 m and 4 × 400 m as the race nears). Where it narrows is the hard work itself. Every hard session is either goal-pace repeats or a threshold run, so for six weeks your quality days feel like two days on repeat. No hills, no fartlek, no progression run. It works, because both sessions are the right ones for this race, but it's a narrower menu than it could be.
Workouts

The opening days look a lot like the running you already do, and that is intended. Nothing here asks for more than you carry right now. The harder days arrive soon, and they work best on legs that begin the block fresh. Notice how the easy days feel when you keep them truly easy. That feeling matters more as the days get busier, and familiar running is the right start for a short build.
M 6mi Easy Run with 4×100m Strides
6 miles easy with 4 × 100 m strides at the end. The opening run of the plan matches the running you already do, so the week starts on familiar ground. Strides are short, relaxed pickups to a fast but smooth stride, with an easy walk back between each. They teach the legs quick turnover without adding fatigue. Keep the 6 miles conversational and save the speed for those closing strides.
Tu 5.5mi Easy Run
5.5 miles easy. This is plain mileage at the volume you already run, the kind that holds the week together. Breathing should stay low enough to talk in full sentences. If the legs feel restless, let them stay restless rather than turning the run into a faster day.
W 3.5mi Threshold Run with 2mi @ Threshold
Warm up 1 mile easy, run 2 miles at threshold around 7:42/mile, then finish with 0.5 mile easy. Threshold is the effort you could race for about an hour, comfortably hard with breathing deep but steady. This opening threshold run is kept short on purpose, a first taste before the block grows. Over the coming weeks this strand grows, a different kind of work from the 5K-pace repeats. Run it even, and ease back if the effort starts drifting toward race effort.
Th 5.5mi Easy Run
5.5 miles easy. Coming the day after the threshold run, this one gives the legs gentle mileage while they absorb that effort. Run by feel rather than by the watch. A pace that feels almost too slow is the right pace here.
F 6mi Easy Run with 4×100m Strides
6 miles easy, then 4 × 100 m strides. Strides again late in the week keeps fast turnover familiar before the weekend's longer run. Each stride builds smoothly to quick, then floats back down. Stop them while they still feel light, not when they start to strain.
Sa 8mi Long Run
8 miles easy. The plan's opening long run sits right at what you already handle, so it should feel familiar rather than daunting. In a 5K plan the long run stays modest, a small slice of the week, and its job is steady endurance under the faster running. Keep the effort conversational from start to finish. If the closing miles drift a little faster on their own, let them, but never chase a pace.
Su Strength Training
The speed arrives now, and with it a different kind of tired. Hard days sit at the front and middle of the week, and everything else stays gentle on purpose. That contrast is what lets the faster running count. If the easy days start to creep quicker, pull them back. Rest between the hard days is part of the training, not time off from it.
M Intervals: 8×400m @ 5k
After 1 mile of easy warm up, run 8 × 400 m at 7:04/mile with 200 m easy jogs between. Cool down for 1 mile. Intervals are repeated fast stretches at 5K pace with easy jogs between them. These are the plan's first repeats at race pace, and the short 400s make them the gentlest way in. 5K pace is the speed the race asks for, so these reps are the most direct practice for the race. Run every rep at the same pace rather than racing the early ones.
Tu 5.5mi Easy Run
5.5 miles easy. The day after the 5K-pace repeats, this run gives the legs easy miles to recover on. Shorten the stride and keep the turnover light. Heavy legs today are normal and usually fade as the run goes on.
W 4.5mi Threshold Run with 3mi @ Threshold
1 mile easy, then 3 miles at 7:42/mile, and 0.5 mile easy to finish. The threshold block grows this week while the effort stays the same, the pace you could race for about an hour. That steady pressure is a different kind of work from the 5K-pace repeats, held well short of race effort. At the midpoint you should still manage a short phrase. If you can only gasp single words, ease off a few seconds.
Th 5.5mi Easy Run
5.5 miles easy. Both harder days now sit behind you, and the long run waits at the weekend. This run sits between them as plain, easy mileage. Keep it relaxed enough that Saturday starts on fresh legs.
F 6mi Easy Run with 4×100m Strides
6 miles easy, finishing with 4 × 100 m strides. The strides are light work, quick feet and tall posture, never a sprint. They keep the legs ready for fast running without costing anything for the weekend. Jog fully between them so each starts fresh.
Sa 9mi Long Run
9 miles easy. At 9 miles this is the longest run so far in the plan. The long run grows a little each weekend through the build, while the harder days carry the race work. Hold an easy, even rhythm the whole way. After a week with repeats and a threshold run, resist the urge to finish fast. Ending relaxed is what lets Monday go well.

Plan Strengths
- Easy running carries about 85% of the volume, so the two hard days each week get to be truly hard.
- Mileage starts at what you already run and builds in small steps to about 40 miles a week, with no sudden jumps.
- Hard days are always separated by an easy day, and new formats never arrive in a big week.
- The Monday repeats build to 5 × 1000 m at goal pace, the full race distance in pieces, in the biggest week of the plan.
- A real taper cuts the volume but keeps goal-pace work in, so the pace stays familiar as the miles come down.
- Sunday's strength session and Friday's strides run all the way into the taper, so the supporting work never drops out.
Weaknesses & Gaps
- Hard work comes in only two flavors, goal-pace repeats and threshold runs, with no hills or fartlek.
- That makes your quality days feel much the same from week to week: the same two efforts for six weeks, with only the rep length changing.
- Only Sunday is free of running, so the plan asks for a six-day habit already in place, at about 34 miles from the first week.
What's missing
Two additions fit without disturbing the plan, one optional and one worth making. If you'd like a tune-up race and there's a parkrun or low-key local 5K two to three weeks before race day, run it in place of that Monday's repeats (in place of, not in addition to), and you'll meet the start, the pacing and the hard middle mile once before it counts. If there isn't one, run the 5 × 1000 m session the way you plan to run the race and let it stand in. The one worth making is some range in the hard work, since every quality session is either goal-pace repeats or a threshold run. Running Friday's strides up a gentle hill on one or two of the build Fridays before the biggest week adds a different kind of effort at almost no cost, which is a coaching preference more than a research finding. From the biggest week on, keep them on flat ground, as the plan's own notes ask.
What the science supports
Shifting training emphasis beats unchanging training
The plan unfolds in three distinct phases. A 4-week build opens at the mileage you already run and climbs to a 39.9-mile peak in week 4, while Monday repeats at 5K pace grow from 400 m to 1000 m and the Wednesday threshold run reaches 4 miles. The week 5 taper eases to about 30.5 miles with the speed kept, and race week drops to about 11. Planned shifts in emphasis like this tend to beat flat training, though the gain in trials was small.

Keep easy days easy, hard days hard
Even with six running days, every day is clearly easy or clearly hard. From week 2, Monday brings repeats at 5K pace and Wednesday the threshold run, with an easy 5.5 miles on Tuesday and Thursday so no hard day follows another. Friday's strides and the Saturday long run stay easy. Trained runners may improve more by keeping most of their running genuinely easy and a few sessions clearly hard than by running at a steady medium effort.
Stöggl & Sperlich 2014; Casado et al. 2022; Kenneally et al. 2018
Polarized training matches or beats threshold-heavy plans
The plan holds roughly 85 percent of your weekly volume at easy pace, and its hardest running is genuinely hard: every Monday from week 2 brings repeats at 5K pace, from 8 × 400 m up to 5 × 1000 m. For trained runners, lots of easy running plus a little truly hard running matches or beats a steady diet of threshold work. A mix with a little more moderate running does about as well.
Stöggl & Sperlich 2014; Kenneally et al. 2018; Silva et al. 2024
Sharp running-load jumps raise injury risk
Daily easy runs stay capped at 6 miles through week 3, even as weekly mileage climbs gradually. No week jumps more than 10 percent from the previous one. That matters, because sudden jumps in running load tend to raise injury risk, most clearly when one run goes well past your longest of the past month. The total grows from 34.5 to 39.9 miles across the build, so Monday's repeats and Wednesday's threshold runs land on legs already used to the load.
Consistent mileage is linked to fewer injuries
Consistent weekly mileage built up over time is generally linked to fewer injuries, not more. That evidence is observational, and not every study agrees. This plan starts at about 34 miles, the volume you already run, and builds only to 39.9 at the peak, spread over six days so no single run carries too much.
