Plan at a Glance
Moving from the novice to the intermediate programs, you encounter a greater degree of difficulty. In Intermediate 1, I steal a day of rest from you on Mondays and suggest you cross-train. Tuesdays and Thursdays are twins, easy running. Wednesday runs are somewhat longer with several days featuring pace runs, workouts where you run at your half marathon pace, to learn that pace. Friday rest before a tough weekend with a few more pace runs and a long run schedule that takes you up to 12 miles just before your 13.1-mile race.
The review below is Buena Vida's full assessment of the plan. We grade every plan against the same detailed, 31-point benchmark. Each measure draws from peer-reviewed sports-science research and proven coaching best practices.

Our Review
Stepping up from Higdon's novice halves means giving back a rest day. Monday becomes a cross-training session, not a day off, and the weekend asks you to run twice. Your half marathon is twelve weeks away. Most days stay easy. Several days do not.
What sets this build apart is how often you rehearse goal pace, the speed you mean to hold for 13.1 miles. A pace run lands almost every week, sometimes on Wednesday and again on the weekend, climbing from three miles up to eight. The trap is letting those pace miles drift back to easy, because eleven weeks of relaxed running makes slow the default. Hold the pace honestly and your legs memorize race effort long before the start line. The back-to-back weekend, a Saturday pace run into a slower Sunday long run, teaches you to run controlled on tired legs, exactly what the closing miles of a half demand.
Two tune-up races, a 5K in week six and a 10K in week nine, sharpen your pacing while the weekend long run works up to twelve miles by week eleven. You will not find strength work, warm-ups, or speed intervals on the grid. This fits a runner who has finished an easier half or run steadily for months and wants a stronger finish without chasing a hard time goal. Read the grid alongside Marathon: The Ultimate Training Guide and you also get Higdon's injury chapters, strength guidance, and missed-day rules; only strength never reaches the calendar. Already running 35 easy miles most weeks? This will read light. Set on a time goal built from intervals rather than steady pace runs? Pick a faster plan.

Structure
Does the plan build you up smartly?
You get a sensible twelve-week shape that climbs in waves, even though no phase is ever named. Easy mileage and the long run build a step at a time, while lighter weeks fall around the week-six 5K and the week-nine 10K. The final week eases into race day. Where it gives ground is detail. Each day shows a distance and, on pace days, a goal-pace tag. The why behind a run and how hard to take it are left for you to fill in.
-
Prevention
Does the plan protect you from injury?
The plan is solid on the basics and thin on the extras. Hard and easy days stay cleanly separated, the long run grows gently, and the rolling load never spikes hard enough to put you at real risk. What is missing is the durability layer. No strength session reaches a single day, and no warm-up is written before the pace runs or tune-up races, so both are yours to add. The one-week wind-down before race day is shorter than ideal, leaving tired legs a narrow window to freshen.
-
Flexibility
What happens when you miss a day?
This build flexes more than the bare grid suggests, once you read it alongside the book. Monday cross-training can become a bike, a swim, or a walk to match how your legs feel before the weekend. The opening note helps you judge whether you are ready to step up from a novice plan. Higdon's chapters add the rest: how to adjust around a niggle, a loose missed-day rule, and effort judged by the talk-test rather than a fixed pace. What the grid itself never prints is which run matters most when a week falls apart, so you carry that guidance over from the book yourself.
-
Readiness
Will the plan deliver race-day fitness?
Long runs, weekly volume, and the goal-pace work all point squarely at the half marathon. The long run reaches twelve miles, about 92 percent of race distance, by week eleven, and the pace runs rehearse the effort you mean to hold. Two tune-up races and a clear peak-then-taper shape give the build sensible checkpoints. The only thing holding readiness back is the single wind-down week, which is standard for a half but short for fully fresh legs.
-
Variety
Are the workouts varied enough?
You meet a reasonable spread of running across the week: short easy runs, a weekend long run, a goal-pace run, and two tune-up races. That easy-heavy mix is the right call for legs adapting to more mileage. What it lacks is variety inside the hard work. The pace run is the only fast session, repeated week after week, so it changes in length but never in shape. A runner who wants their speed work to feel different from week to week will find the pattern repetitive.
Plan Strengths
- A pace run lands almost every week and grows from three miles to eight, so the effort you need on race day becomes second nature instead of a guess.
- The Saturday pace run into a slower Sunday long run trains you to hold form on tired legs, the skill the last miles of a half demand.
- Most weekends add only about a mile to your long run, so the climb to twelve miles in week eleven never lands as a jump your legs cannot take.
- A 5K in week six and a 10K in week nine each land on a lighter week, so you sharpen pacing under a bib while your training load steps back.
- Hard days and easy days never collide; the lone weekday pace run sits between easy runs and rest, giving your legs room to absorb each effort.
- Several weeks stack two pace runs, one midweek and one on Saturday, so goal effort shows up far more often here than in an easier build.
Weaknesses & gaps
- Trading Monday's rest day for cross-training leaves only Friday fully off, so the week runs leaner on recovery than the novice plans you may be stepping up from.
- Hard-day variety is thin: the pace run is the only fast session and it changes length but never form across the twelve weeks.
- No strength session ever lands on a training day, even though stronger legs are what keep the extra mileage from breaking you down.
- Your pace runs and tune-up races all start cold, because no warm-up appears anywhere on the grid for you to follow.
- Lose a few days to a cold or a work crunch and the schedule goes quiet; the catch-up rule sits in a book chapter, not beside the run.
- Race day arrives after a single wind-down week, so legs carrying eleven weeks of work get only a short window to freshen up.
What this plan does not give you
The thinnest spot is recovery. Trading Monday's rest for cross-training leaves Friday as your only day fully off, so protect that day and keep the Monday session genuinely easy rather than a third hard effort. Strength work is the next gap. Hal Higdon's book recommends it, but no session ever lands on a training day, so aim for two short routines a week on your Monday cross-training or rest days. There is no warm-up on the page either. Before each pace run and the two tune-up races, give yourself five to ten minutes of easy jogging and gentle movement instead of starting cold. And if a cold or a work crunch costs you a few days, the grid offers no catch-up rule. The safe move is to repeat the week you missed rather than cram the lost miles back in.
What the science supports
Easy aerobic volume is the foundation
About seven of every ten miles in this plan are easy and conversational: three short midweek runs plus a long Sunday run that stays relaxed. Research on trained runners finds that keeping most weekly mileage easy is what lets the harder efforts work. The single weekly pace run sits on top of that easy base rather than crowding it out, which is the balance the evidence supports.

Tune-up races sharpen pacing skill
Two tune-up races punctuate the build, a 5K in week six and a 10K in week nine. Runners who race a shorter event before a goal race tend to pace the big day better, steadier and less likely to start too fast. The benefit here is practice, not a fitness boost: these mornings let you rehearse race effort, your start-line nerves, and your warm-up in a low-stakes setting before the half itself.
Race-pace specificity hinges on physiology
A pace run at goal half-marathon effort appears almost weekly and grows from three miles to eight. For a runner whose half pace sits easier than their threshold, the pace where effort turns hard, this work pays off as pacing rehearsal rather than a deep fitness change. Treat the pace runs as practice at holding race effort, which is exactly what builds the discipline to not start the half too fast.

Tapering improves race performance by 2-6%
The final week cuts the running back sharply before race day: a short pace run and a two-mile easy run replace the heavier weekend work of week eleven. Easing the load in the last week while keeping a touch of pace lets accumulated fatigue clear so your fitness shows up on race day. One easy week is the standard wind-down for a half marathon, and this plan follows it.
Strength training improves running economy
This plan never schedules strength work, and that is a real gap worth bridging yourself. Two short strength sessions a week make trained runners more efficient, so they use less energy at the same pace, and they help guard against injury as mileage climbs. Slot them onto your Monday cross-training day or a rest day, kept away from the pace runs, and hold the habit for the full twelve weeks.
