Intermediate Half Marathon Training Plan
You've raced one. 12 weeks to race it faster.
Training for a half marathon at this level asks you to handle more than a weekly long run. You need to hold controlled effort for longer stretches, recover between purposeful sessions, and keep your easy days easy enough to support the work. This plan gives each run a defined job, then explains how that job should feel and what to change when your schedule, recovery, or conditions do not cooperate.
12 weeks · 5 runs a week · peaks at 43 mi/week · longest run 14 miles
One-time purchase, yours for life. Delivered through Final Surge.
That’s $2.50 a week — 50¢ for every coached run in the plan.

What Makes This Intermediate Half Marathon Training Plan Different
Most plans tell you how far to run. This one tells you how it should feel — and what to do when it doesn’t.
A Real Week From The Plan
Below is week 7, the last week of the build block.
Cruise intervals Tuesday, 6 easy Wednesday, an 8-mile steady-state progression Thursday, 12 miles Saturday, 5 recovery Sunday. 39 miles, and it isn’t the biggest week. Every day in all 12 weeks is written like you see below.
Week 7 – Build Phase
This week continues building aerobic strength, pacing efficiency, and race-specific endurance as your workouts and long runs become more demanding. The focus remains on controlled progression and learning how to maintain strong, sustainable effort over longer periods of time.
You should begin noticing improved rhythm and confidence during sustained efforts while continuing to prioritize recovery and consistency between workouts.
Focus this week on:
– Staying controlled during sustained efforts
– Running easy days truly easy
– Maintaining efficient pacing and relaxed form
– Building confidence late in long runs
– Supporting recovery between harder sessions
Remember: strong half marathon racing comes from patient aerobic development and consistent training—not forcing every workout.

Every day opens with the workout, an activation routine, how it should feel, one coaching cue, how to adjust it, and what it’s building. All 60 runs are written that way.
The 12 Weeks, Phase By Phase
The plan runs for 12 weeks, with recovery weeks in Weeks 4 and 8 before the peak, taper, and race-week phases.
| Phase | Weeks | What happens | Long run reaches |
|---|---|---|---|
| Foundation | 1–4 | 5 runs begin at 26 miles and build to 32, with tempo work, easy running, steady progressions, long runs, and recovery runs. Week 4 is a recovery week, and mileage drops to 26. | 9 miles |
| Build | 5–8 | Weekly mileage builds from 34 to 39 miles as tempo intervals, cruise intervals, and steady-state progressions develop. Week 8 is a recovery week, and mileage drops to 31. | 12 miles |
| Peak | 9–10 | The two highest-volume weeks reach 41 and 43 miles, with longer tempo work, race-rhythm progressions, and the peak long run. | 14 miles |
| Taper | 11 | Weekly mileage decreases to 33 miles while tempo intervals, progression running, and a shorter long run maintain rhythm. | 10 miles |
| Race Week | 12 | The week includes 16 training miles, a strength session, a pre-race shakeout, and the 13.1-mile race. | 13.1-mile race |
What This Asks Of Your Week
The honest answer, by phase, because “do I have time for this?” is worth answering before you buy, not after. Totals include strength, mobility and optional recovery sessions, and will shift with your own pace.
Foundation, Weeks 1–4: approximately 5–6.5 hours a week
Build, Weeks 5–8: approximately 6–7.5 hours a week
Peak, Weeks 9–10: approximately 7.5–8 hours a week
Taper, Week 11: approximately 6–6.5 hours
Race Week, Week 12: approximately 5 hours, including the race
The plan opens at 26 miles rather than building to it. If week 1 fits, the rest will.

Frequently Asked Questions
Week 1 includes 26 miles across 5 runs. You are ready to begin if that is close to your current weekly training rather than a new personal high. You do not need a previous half marathon, but you should already be comfortable running 4 or 5 days a week and recovering well enough to repeat that schedule.
The Beginner plan runs 3 days and peaks at 20 miles. This plan starts at 26 miles, peaks at 43, adds tempo and cruise-interval work, and takes the long run to 14 miles instead of 11. The difference is not simply more mileage; this plan begins from a higher current training base and uses 2 purposeful workouts most weeks.
Yes, and it is deliberate. The plan distributes those 43 miles across 5 runs, including tempo or cruise-interval work, a steady progression, an easy run, a recovery run, and a 14-mile long run. If that weekly volume does not fit your current training or available time, the Beginner Half is the lower-volume option rather than a shortened version of this schedule.
You will complete 5 runs a week. Weeks 1–11 also include 1 strength and mobility session and 1 recovery day that can be used for optional light cross-training or complete rest. Race week keeps 5 runs by replacing the scheduled long run with the half marathon and includes 1 scheduled rest day.
Plan for approximately 5 to 6.5 hours during Foundation, 6 to 7.5 during Build, and 7.5 to 8 during Peak. Taper drops to approximately 6 to 6.5 hours, while Race Week takes about 5 hours including the race. These totals include strength, mobility, optional recovery sessions, and will shift with your own pace.
The schedule uses tempo runs, cruise intervals, steady-state runs, progression runs, easy runs, recovery runs, and long runs. Each week balances the harder sessions with lower-effort running and a recovery day. There are no track sessions in this plan; the structured workouts focus on sustained aerobic effort and controlled progression rather than shorter repetitions.
No. Every run includes an RPE target that describes the intended effort, along with guidance for how the session should feel. That lets you adjust for heat, hills, fatigue, terrain, or a difficult week without treating 1 fixed pace as the only successful outcome. The structure remains the same even when the pace produced by that effort changes.
Move forward with the schedule rather than stacking the missed mileage onto another day. The plan includes guidance for shortening or skipping sessions when recovery or scheduling gets in the way. 1 missed run does not require a restart, and trying to catch up can interfere with the easy running and recovery placed between harder sessions.
Schedule a 15-minute consultation and we’ll talk it through before you buy. If you would rather have someone adjusting the schedule as you go, online run coaching is the other route. Coaching provides a more individualized option when a fixed plan does not fit your current volume, schedule, or need for feedback.
