Plan at a Glance
You raced a 5K within the past month, and sub-22 looked close enough to touch. You're running about 26 miles a week across four days. You don't need to build fitness from scratch. You need the fitness you already have pointed at one pace.
So the week has two hard days and two easy ones. Monday is repeats at goal pace, starting with 400s and stretching to 800s, then 1000s, until the pieces add up to the whole race. 5K pace sits close to the speed where your oxygen uptake tops out, which makes time spent there the most direct practice for this race. Wednesday is a threshold run, the effort you could hold for about an hour: comfortably hard, steady, never a strain. It's what lets goal pace feel held on race day rather than survived. Friday is easy with a few strides. Saturday is a long run at the pace you can talk at, and it grows past 12 miles, which surprises people in a 5K plan. Tiredness isn't the proof of work here. The long run is there to carry the fast days, not to compete with them. Tuesday and Thursday are for strength, and Sunday is off.
Each Monday session is won or lost on its first repeat. Your legs are rested, goal pace feels slow, and every instinct says go. Run it at goal pace, not under it. The race asks the same thing in its first half mile, and going out too fast there is the usual way a sub-22 attempt slips away.
After the biggest week, the running drops by about a quarter while the speed stays in, with fewer repeats on fresher legs. Race week is a short touch of pace, an easy run, a shake-out, and the 5K on Sunday.
Below is the full Buena Vida review. Every plan is held to the same detailed, 30-point benchmark, with each measure traced back to peer-reviewed sports-science research and proven coaching best practices.

Our Review
You're near sub-22 already and need the last step, not a rebuild, and this plan doesn't try to remake you. It holds your mileage close to where it is, keeps most of it easy, and spends two days a week on the two things that move a 5K this close to race day: time at goal pace and threshold work. Both strands grow through the build, Monday's repeats and Wednesday's threshold run never touch, each repeat and threshold session starts with an easy mile and carries a note on its purpose, and the taper trims volume while keeping the speed. The gaps are small and fixable: a narrow range of hard sessions and a slightly busy first week of repeats. Both are easy to work around, and neither touches the core of the build. If your recent 5K says you're close and four days a week fits your life, run this plan.

Structure
Does the plan build you up smartly?
Each of the three stages has a job you can see: a 4-week build, a taper week, and race week. Inside the build, both hard sessions grow week by week, the Monday repeats from 400s to 1000s and the Wednesday threshold run from 2 miles to 4. None of those sessions leaves you guessing, since each comes written out from warm-up to cool-down with a note on why it's there.

Prevention
Does the plan protect you from injury?
Restraint is what this plan does best. A runner this close to a goal usually wants to treat every run as a chance to get faster. The plan asks you not to. About four of every five miles are easy, and Tuesday's strength session keeps Monday's repeats and Wednesday's threshold run apart. Keeping easy days easy is what lets the hard days be hard, and trained runners tend to improve more that way than on a steady stream of medium effort. Weekly mileage goes from 26 to 28 to 30 to just over 31, steps small enough to suit tendons and bones. Those usually take longer to catch up than your heart and lungs, and big jumps in running load tend to raise injury risk. There's no cutback week inside the build, and in a block this short the taper does that job. The one thing to watch is the week the repeats begin. The first interval session arrives in the same week the mileage climbs. The rise is small and the session is the shortest of the build, so it's a mild bump, not a hazard.
-
Flexibility
What happens when you miss a day?
The plan makes the priorities easy to read. It marks three sessions to protect: the Monday repeats, the Wednesday threshold run, and the Saturday long run. Friday's easy run and the strength days are the first to give way. If you miss a Monday, move it to Tuesday and push the threshold run to Thursday so the two hard days stay apart. Don't run them back to back to catch up. If you miss a long run, shorten the next one rather than doubling up. In race week, skip anything you miss, since those last days are for resting rather than catching up.
-
Readiness
Will the plan deliver race-day fitness?
Nothing a sub-22 race needs is left out, and it all comes in the right order. The longest run is four times the race distance, all of it easy, and that base is what lets the fast work land without burying you. Race-specific work shows up in every week and grows toward the race. The opening week has the first threshold run, then the Monday repeats at goal pace take over and lengthen until, in the biggest week, they add up to the full race distance at race pace. From the peak of about 31 miles, the week drops to about 23 and then to a light race week, and a structured taper like that usually serves race day better than holding training steady.
-
Variety
Are the workouts varied enough?
There's more variety in the week than its two hard days suggest. You get easy runs, long runs, intervals, threshold runs, and the race itself, plus strides every Friday until race week. The Monday sessions change shape as the weeks go, so the same pace never feels like the same workout twice. The limit is that all of the hard running comes in two forms, intervals and threshold. There are no hills, no fartlek, no progression runs. For a focused race block that's a reasonable trade, though it narrows the kinds of stress your legs see.
Workouts

Everything here sits inside what your legs already handle, and that is by design. The aim is to reach the harder days fresh rather than already in debt. Pay attention to how the faster moments of the week feel, because that feel becomes your reference for what follows. You know how to read your own effort by now, so let that judgment set the pace on the easy days. Sleep and regular days matter more than any heroics right now.
M 6.5mi Easy Run with 4×100m Strides
6 miles easy, then 4 × 100 m strides with 100 m easy between. Strides are smooth pickups to a fast but relaxed stride, never a sprint, and they teach your legs to move quickly without strain. The opening run of the block should feel almost too easy, which is the right place to start. Keep the jogs between strides unhurried so each one starts fresh.
Tu Strength Training
W 3.5mi Threshold Run with 2mi @ Threshold
3.5 miles with 2 miles at threshold, 7:42/mile, between a 1-mile warm-up and a 0.5-mile cool-down. Threshold is the effort you could race for about an hour: comfortably hard, steady, and never a strain. This is the opening taste of a strand that runs through every week, and it starts short on purpose. The run grows from here, and it is what lets 5K pace feel held on race day. Run it even, and finish feeling you could have kept going.
Th Strength Training
F 6.5mi Easy Run with 4×100m Strides
6 miles easy, then 4 × 100 m strides with 100 m easy between. Friday stays easy because the long run follows tomorrow, so keep the effort truly relaxed. The strides at the end remind your legs of quick turnover without costing anything for Saturday.
Sa 9.5mi Long Run
9.5 miles easy. The opening long run sets the baseline for the Saturday runs that follow. It is also the furthest you will have run in the block so far. A 5K plan keeps the long run modest, because its job is a broad base under the faster work, not marathon endurance. Hold a conversational effort the whole way, and finish feeling you could run a couple more miles.
Su Rest
The hard running steps up here, and the body notices. The day after the fast work may feel heavier than usual, which is normal rather than a warning. The easy days earn their place now by staying easy, so leave the urge to press them for another time. A pair of hard days in one week is a new rhythm for many runners, and it takes a little while before it feels routine. Keep showing up on the days the calendar asks for.
M Intervals: 8×400m @ 5k
Warm up 1 mile easy, then 8 × 400 m at 7:04/mile with 200 m easy jogs between, and cool down 1 mile. The block's opening day of 5K pace repeats starts with the shortest ones. 5K pace sits close to the speed that pushes your oxygen uptake to its ceiling, so time at this pace is the most direct practice for the race. The 400s are short enough that the pace should feel quick but controlled. Aim for even splits rather than a fast opener.
Tu Strength Training
W 4.5mi Threshold Run with 3mi @ Threshold
4.5 miles with 3 miles at threshold, 7:42/mile, after a 1-mile warm-up and before a 0.5-mile cool-down. Coming 2 days after the 400s, this run asks for a longer, steadier kind of hard. The threshold block has grown, so start at the low end of the effort and let it build only if it feels easy to hold. You could keep going at this effort, but you would not want to chat.
Th Strength Training
F 7.5mi Easy Run with 4×100m Strides
7 miles easy, then 4 × 100 m strides with 100 m easy between. This run sits between the Wednesday threshold run and the Saturday long run, so its value is in the easy part. Run it slow enough to chat the whole way. Keep the strides crisp and relaxed rather than all out.
Sa 11mi Long Run
11 miles easy. The long run grows a little while the hard days stay on Monday and Wednesday. No run in the block has gone this far yet. Keep the effort conversational, even on the back half. If the week's faster running is still in your legs, slow down rather than cut the run short.

Plan Strengths
- Strength sits on Tuesday and Thursday, away from both hard days, and Sunday is a full rest day every week.
- The threshold run shrinks back to its opening length in the taper, so it keeps the feel without adding fatigue.
- Effort is described by feel throughout (the pace you can talk at, an hour's race effort), so the plan reads the same on a hot day or a hilly route.
- The race-day note coaches the first half mile directly, where a sub-22 attempt usually slips away.
Weaknesses & Gaps
- All the hard work is intervals or threshold, with no hills, fartlek, or progression runs.
- A lot rides on Saturday, since the long run makes up about two fifths of the miles in the biggest week.
- The first interval session arrives in the same week the mileage starts to climb.
What's missing
Every hard session here holds a set pace, with no hills or fartlek anywhere. One coaching option is to run Friday's strides up a gentle hill once or twice in the build, which keeps the easy day easy and adds a different kind of effort to your week. And because the first week of repeats is also a week of rising mileage, keep that Friday run gentle, and cut it short if the 400s are still in your legs.
What the science supports
Shifting training emphasis beats unchanging training
This plan divides six weeks into three distinct phases. A 4-week build grows every strand together: Monday repeats at 5K pace stretch from 400 m to 1000 m, the Wednesday threshold run grows from 2 to 4 miles, and the Saturday long run climbs from 9.5 to 12.5 miles. Week 5 cuts the running by about a quarter and keeps the speed, and race week keeps only a few 400s. Changing the emphasis like this tends to beat holding one fixed mix.

A real taper sharpens you for race day
The taper runs 2 weeks. Week 5 drops from the 31.4-mile peak to 23.5 miles but keeps 4 × 800 m at 5K pace and a 2-mile threshold run. Race week falls to about 7 miles before Sunday's 5K, with 4 × 400 m on Tuesday to keep the speed. A taper of up to 3 weeks that cuts running by roughly 40 to 60 percent while keeping intensity improves race performance compared with not tapering.
Keep easy days easy, hard days hard
Every week splits clearly. From week 2 through the taper, Monday brings repeats at 5K pace and Wednesday the threshold run, with a strength day between them so no hard run follows another. Friday is easy with strides, and the Saturday long run stays conversational. Trained runners tend to improve more on a split like this, mostly easy and clearly hard, than when they run everything at a medium effort.

Two strength sessions a week is enough
Most runners get the performance benefit of strength training from about 2 sessions a week, and in pooled trials, adding more sessions did not add benefit. This plan schedules exactly 2, on Tuesday and Thursday, in every week of the build and the taper. Each sits on a day with no running, so the strength work never crowds Monday's repeats, Wednesday's threshold run or the Saturday long run.
Blagrove et al. 2018; Balsalobre-Fernández et al. 2016; Llanos-Lagos et al. 2024
Sharp running-load jumps raise injury risk
Volume progression through the plan is deliberately conservative. It opens at about 26 miles, close to what you already run, and adds no more than 2 miles a week to a 31.4-mile peak in week 4. The largest rise is about 8 percent. Big jumps in running load tend to raise injury risk, and weekly jumps above about 30% are a warning sign. Staying close to what your legs already handle keeps the build far below that warning line while the speed work arrives.
