Running Plan Review Buena Vida Run Club's 10-Week Sub-2 Half Marathon (4 days)
Plan at a Glance
Sub-2 is the half marathon goal that turns running into pace math. Two hours over 13.11 miles works out to nine minutes per mile, held the whole way. That number is what makes the build hard. Goal pace isn't a stretch you reach once on a good day; it's a pace you have to land on every Wednesday, with race morning still ten weeks off. The challenge isn't running fast once. It's running 9-minute pace on a regular Wednesday, then doing it again the next week.
Most runners chasing sub-2 have already finished a half marathon, sometimes a few. They know what 13.11 miles costs at a comfortable pace. The jump to sub-2 isn't really a fitness leap. It's a pace-discipline leap. The most common mistake is running every easy day a little too fast, treating recovery runs as moderate efforts. That habit caps the long run and starves the legs of the rest that lets harder days build into speed.
Buena Vida built this 10-week plan for runners who already know the distance and want to take ten or fifteen minutes off. It runs four days a week with strength on Tuesday and Friday, interval work on Wednesday (short fast reps at goal pace, with rest between), an easy Thursday, and a long run on Saturday. Peak weekly volume reaches 37 miles in week 7, with cutback weeks at week 4 and week 8 so the build doesn't overheat.
What follows is our full review of the plan. Buena Vida grades every plan on the same detailed, 31-point benchmark. Each measure comes from peer-reviewed sports-science research and proven coaching best practices.

Our Review
This is a compressed runway: ten weeks, four runs a week, and a half marathon you already know the cost of. The plan spends the runway on contact with goal pace rather than on peak volume. From week 3 onward, you'll meet 9-minute pace on Wednesday in intervals that scale from seven half-mile reps to nine three-quarter reps. You'll close two long runs at race pace before week 9, then run a 6-mile dress rehearsal at goal pace inside an 11-mile Saturday. Peak weekly volume tops 37 miles in week 7. Real cutbacks at week 4 and week 8 keep the build from running hot.
Where this plan is decided isn't on Wednesday's intervals; it's on Thursday's easy run. Sub-2 chasers turn the day after intervals into a second hard day by accident. That compounds: Thursday at threshold makes Friday's strength flat, which makes Saturday's long run break. The plan keeps three calendar days between hard sessions specifically so that Thursday can be soft, with strength sitting on Tuesday and Friday off your running days. Your job is to hold the line.
If you already know what 13.1 miles costs and want to know what ten or fifteen minutes faster asks of you, this plan is built for that. If you cycle or swim on rest days, you'll need to fit that yourself; cross-training isn't on the calendar. If you tend to drift toward threshold pace on weekday runs, you'll need to set that limit yourself.

Structure
Does the plan build you up smartly?
The shape of the ten weeks is easy to read off the calendar. Five named phases run base, build, peak, taper, and race week, and the Saturday long run climbs from 5 miles to a 12.5-mile peak before stepping back. Two cutback weeks (week 4 and week 8) pull volume down by roughly a quarter so the build never piles up faster than the legs can absorb it. Strength holds its place every week, and the peak eases into the taper across two weeks rather than one, so the load comes off in stages.
-
Prevention
Does the plan protect you from injury?
Mostly, with one jump that runs hot. About 83 percent of the miles stay easy, the right share for an intermediate half marathoner, and the one hard interval day never sits next to the long run (three calendar days separate them). Strength lands on Tuesday and Friday, off the running days, so it never doubles up on a hard effort. The one rough edge: week 5 jumps about 63 percent over the week 4 cutback, a sharp single step. It comes off a deliberate deload, so the legs are fresh for it, but that week asks for honesty about easy effort more than any other.
-
Flexibility
What happens when you miss a day?
Miss an easy day and the plan absorbs it without much cost. Miss the Saturday long run and you're into harder choices, because that run is where most of the race-specific work lives. Every session carries a priority, so when a week shrinks the order is clear: the Wednesday intervals and the long run come first, the easy runs next, strength last. What the plan doesn't hand you is a rule for slotting a missed long run back in. That call stays yours.
-
Readiness
Will the plan deliver race-day fitness?
By race morning the legs have rehearsed the goal more than 30 miles' worth. Goal pace (9 minutes per mile, the number that gets you under two hours) shows up in week 3 and stays on the calendar through week 9. The peak long run closes with 3 miles at race pace off tired legs, and the week 9 dress rehearsal carries 6 miles at goal inside an 11-mile run. The hardest of that pace work lands in the back third of long runs, which is exactly where a half marathon is won or lost.
-
Variety
Are the workouts varied enough?
Each phase brings a different kind of session, so the weeks rarely repeat themselves. Base weeks are easy running only. Build weeks add goal-pace intervals (short fast reps with a jog between) and a session of hill repeats. Peak weeks tack race-pace finishes onto the long runs, and week 9 folds goal pace into a long run one last time. The intervals themselves grow across the plan, from half-mile reps up to three-quarter-mile reps and from 7 of them to 9, with short pickups (strides) on easy days rounding out the menu.

There is a particular feeling to the first week of any plan, and most of it has nothing to do with the running itself. You have decided to point your training at a specific outcome over the next ten weeks, and that choice is doing some quiet work in the background of every easy day this week. Take it lightly. There is nothing to prove in week one, and a lot to settle into.
M 5mi Easy Run
Five miles at a pace where talking would still work. This is the first run of the plan, and the legs don't know that yet. Keep the pace boring on purpose. The first run of any ten-week plan often feels heavier in the head than in the legs, like the body is checking whether you mean it this time.
Tu Strength Training
W 5mi Easy Run
Five easy miles, second run of the week. Two run days in, your body will start telling you which leg is tighter. That's normal early in a build. Don't fix it on the run. Fix it after.
Th 5mi Easy Run
Five easy miles, conversational. Three runs in, you may feel the load a little. That's the body adjusting to load rather than pushing back. Slow when it asks. Conversational pace is the ceiling here.
F Strength Training
Sa 5mi Easy Run
Five miles at easy effort, the first long run of the plan. Five is short for a long run, but the day on the calendar matters more than the distance this week. This is the run that'll grow every Saturday from here. Treat it as the longest run of the week and slow it accordingly. Most runners spend their first long run waiting for it to feel hard. Let it not.
Su Rest
What is happening underneath these easy days is not always visible from the outside. Your aerobic system is starting to remodel quietly, your tendons are learning to absorb a little more, and the rhythm of running on the same days each week is starting to settle into something familiar. Most of the meaningful work in a half-marathon block happens at the unflashy intensities, and this is one of those weeks. Stay patient with how slow the easy effort is supposed to feel.
M 5.5mi Easy Run
Five point three easy miles. A small step up from week 1, same effort. You may feel a touch of fatigue from last week's strength sessions. That's fine. Hold conversational pace and let the legs warm up gradually.
Tu Strength Training
W 5.5mi Easy Run
Five point three easy miles, mid-week. By now the days of the week should be settling into a pattern. If you feel sluggish, slow down. The goal of a midweek easy is to show up rather than chase a pace.
Th 5.5mi Easy Run
Five point three easy miles. Same effort, third run of the week. This is the run where the body starts feeling like it knows what it's doing on Thursdays. Trust the boring pace.
F Strength Training
Sa 6.5mi Easy Run
Six point three miles at easy effort. A one-mile bump from last Saturday's long run. Treat the extra mile as a continuation of last week rather than a test. You should finish feeling like you could run another mile, even if you'd rather not.

Plan Strengths
- From week 3 onward, you'll meet 9-minute pace on Wednesday and carry it through week 9. By race morning, goal pace will feel familiar in your legs rather than abstract on the watch.
- Three calendar days separate every Wednesday harder session from every Saturday long run. The Thursday after intervals is genuinely easy by design.
- By week 7 you'll have closed two long runs at race pace, then run a 6-mile dress rehearsal at goal pace in week 9. Mile 11 of the race won't be a guess.
- Real cutbacks at week 4 and week 8 drop volume by roughly a third. They let last week's load convert into fresh legs rather than asking you to survive it.
- Strength on Tuesday and Friday holds from week 1 through race week, off your running days, so lifting builds you rather than draining Saturday's long run.
Weaknesses & Gaps
- Cross-training isn't on the calendar. If you cycle or swim on rest days, you'll need to fit that work in yourself without guidance from the plan.
- You'll have to police your own easy pace. The plan trusts you to keep Thursdays slow, and drifting toward threshold there quietly breaks the week.
- Week 5 jumps about 63% in volume off the week-4 cutback while adding new hill repeats. That single co-escalation week asks for care if your legs run sensitive.
- Race-week mileage runs near 26 miles. If your legs need more rest than the plan offers, you'll want to subtract a Wednesday or shorten the shake-out yourself.
What's missing
This plan doesn't put cross-training on the calendar. If you cycle, swim, or row on rest days, you'll need to fit that in yourself, and the simplest rule is to keep those sessions easy on a Sunday or Monday rather than stacking them next to Wednesday's hard run. The plan also trusts you to keep easy days easy. If you tend to drift toward a moderate pace on Thursdays, set an upper limit on your watch (try 10:30 or slower) and treat it as a ceiling, not a target. Week 5 is the other spot to watch, since volume climbs sharply off the week-4 cutback just as hill repeats arrive; if it feels like too much at once, hold the hills shorter that first week. Race week still runs about 26 miles, on the higher side for a taper, so drop Wednesday's reps or skip the shake-out if your legs have always needed more rest.
What the science supports
Keep easy days easy, hard days hard
The day after your Wednesday intervals is Thursday: four or five miles at conversational pace. That's not a second hard day by accident. Three calendar days separate every Wednesday goal-pace workout from Saturday's long run, by design. This separation means Thursday feels genuinely easy to your legs, which lets Saturday work well, which sets up the next week. The plan trusts you to run Thursday slow enough that it actually counts as recovery, not a light version of hard.

Race-pace specificity hinges on physiology
Your goal pace of 9:00 per mile sits right where your body transitions from easy effort to hard. On Wednesday, you run 7 then 8 then 9 repeats at this pace with short breaks between. On Saturday starting week 6, your long run closes with 2 to 3 miles at this same pace on tired legs. That repeated contact with goal pace is what shapes you toward sub-2. You're training the specific effort level your race demands, not just rehearsing a pace you'll hold.

Periodization beats constant-load training
Your plan has five named phases moving from base through build, peak, and taper toward race day. Week 4 cuts volume by roughly a third, then week 8 does the same, so the hardest training isn't sustained back-to-back. This structure lets each phase deliver what it's supposed to without overheating the build. Periodization like this produces better race-day fitness than running the same effort every week.
Bradbury et al. 2020; Tønnessen et al. 2014; Casado et al. 2022
Easy aerobic volume is the foundation
Four of your seven days are easy runs. Week 1 runs mostly at conversational pace, around 20 miles total, all low-intensity. Even in peak week 7 when you hit 37 miles, roughly 31 miles sit at easy effort and only 6 at hard. That easy-run foundation is what lets your body absorb Wednesday's goal-pace intervals without breaking. You don't build speed on the hard days. You build it on top of what the easy days create.
Haugen et al. 2022; Casado et al. 2022; Tønnessen et al. 2014
Tapering improves race performance by 2-6%
Volume drops starting week 8 and stays low through week 9. Week 10 is race week. You'll do two-mile easy runs on Monday and Wednesday and Thursday plus a two-mile shake-out the day before the race. You'll drop from 37 miles in peak week to around 26 miles in week 8 and less afterward. This isn't a sign the training is over. It's when your legs finally recover fully, and the fitness you've built expresses itself on race morning.
