THE HALF MARATHON
BLUEPRINT

12 weeks. No fluff, no filler. Just the stuff that actually gets you to the start line ready to run your best 21.1km.

Who this is for: you can already run 5-10km without dying. Good. That is the entry fee. Show up 4-5 hours a week for 12 weeks and something ridiculous happens at the finish line.
How The Plan Works

Phase 1 — Base

Weeks 1-4. Boring? Yes. Skip it? Don't you dare. We are building the engine that carries you through phases 2 and 3. Easy kays only.

Phase 2 — Build

Weeks 5-9. Now we cook. Intervals, tempo runs, long runs up to 18km. This is where you earn it. Not today Satan.

Phase 3 — Taper

Weeks 10-12. Volume drops. You will feel slow and restless. That is the plan working. Sit down, eat your carbs, trust the process.

The Rules. Read Them.

Pacing Guide

Find your goal time, get your paces, tattoo them on your brain. All per kilometre. Do not freestyle this.

The 80/20 rule: 80% of your weekly kays at easy Zone 2 pace. 20% hard. Most runners flip this and wonder why they are tired all the time and getting slower. Science is not optional.

Easy / Zone 2 Pace

Goal FinishEasy PaceFeel
Under 1:455:30–6:00/kmConversational. Nose breathing possible.
1:45–2:006:00–6:45/kmComfortable. Full sentences.
2:00–2:206:45–7:30/kmRelaxed. HR below 75% max.
Over 2:207:30–8:30/kmSlow feels right. That is the point.

Tempo Pace

Under 1:454:30–4:45/kmComfortably hard. 3–4 word answers.

What Are You Actually Doing

Every session explained so you are not just vibing out there with no idea.

Easy Run

Zone 2. Full sentences. Nose breathing if possible. If you are puffing, slow down. Yes, slower than that. This is not a race.

Tempo Run

Comfortably hard. 3-4 word answers only. Sustained 20-40 min. Raises your lactate threshold. Not fun. Very effective.

Intervals 800m

Hard repeats, easy jog recovery. 5x800m at 5k effort, 90 sec between. It hurts. That is literally the point.

Intervals 1600m

Longer repeats at 10k effort. More race-specific. Full 2 min recovery. Do not shortcut the rest, it matters.

Race Pace Run

Sustained at your goal pace. Your body needs to know what this feels like before race day. Practice the feeling.

Long Run

Always easy. Always. Time on feet, not speed. This one also builds the mental toughness. Respect the long run.

Strides

6-8x 20-second accelerations, full recovery between. Bolted onto easy runs. Keeps your legs from forgetting how to go fast.

Deload Week

Volume drops 30%. You will feel like you should do more. You should not. The body adapts during rest, not during the grind. Embrace it.

Training Tracker

Set up your HR zones first so we know what we are working with. Then log every run. After each one, grab your story card and go show off.

Flat surface, HR monitor, proper warmup. Takes about 25 min. Do not attempt this cold or you will have a bad time.

  1. Warmup: 10 min easy jog, then 5 min at moderate effort.
  2. Run 3x 1 min at maximum effort with 1 min easy jog between each.
  3. On the final rep, sprint the last 20 seconds.
  4. The highest HR recorded is your Max HR. Enter it below.

Already know your zones from Garmin, Polar or Whoop? Legend. Enter each zone's upper limit below and we are off.

No zones set yet. Go do the test or enter them manually. We need these to actually make sense of your runs.

Run History

no runs yet, sparky. get moving.
Race Day. Let's Go.

You have done the work. Do not blow it on race morning by being an idiot.

One rule to rule them all: nothing new on race day. Not shoes. Not food. Not socks. Not a new warmup routine you saw on TikTok at midnight. You know what works. Use that.
After. Please Rest.
