Half-marathon Training Plan to Run 1:30 — 12 Weeks

A science-backed reference framework, ready to be adapted to your Strava data, your weekly schedule, and how you actually feel.

Duration

12 weeks

Peak volume

50–70 km

Runs / week

5-6

Goal pace

4:16/km

TL;DR

Run a 1:30 Half-marathon with a 12-week structured plan. Peak weekly volume 50-70 km, 5-6 runs per week, goal pace 4:16/km. Pre-requisite: a recent 10K in 42:00. Synthesized from Jack Daniels' VDOT, Pfitzinger, Higdon and Hansons frameworks — Coach Leo adapts the plan daily to your real training data.

Are you ready for a 1:30 plan?

Targeting 1:30 requires a baseline of current running fitness. The most reliable signal: a recent 10K you can run in 42:00 or under. If you are below this level, start with a less aggressive goal — running too fast in training is the #1 cause of injury at this level.

Target training paces

These paces come from Jack Daniels' VDOT system calibrated to a 51 VDOT (the physiological ceiling for your goal). Every session in the plan falls into one of these zones — never random.

How the 12-week plan is structured

Every credible marathon plan follows a four-phase progression: base, build, peak, taper. The phase durations adapt to the distance and the runner's level — here is the split for this plan.

Base

2 weeks

2 weeks establishing the aerobic foundation. Mostly easy running, no real intensity. Goal: get the legs moving consistently and build a weekly rhythm.

Build

4 weeks

4 weeks introducing quality work — intervals, threshold runs, hill repeats. Volume increases gradually. This is where fitness starts to break upward.

Peak

4 weeks

4 weeks of race-specific work. Long runs reach maximum distance, marathon-pace work appears in long runs, hardest sessions of the cycle. Mental and physical stress peak here.

Taper

2 weeks

2 weeks of reduced volume (40-60% less). Some intensity stays to keep the legs sharp. Glycogen restores, micro-damage heals, confidence builds.

Three key workouts in this plan

Every plan needs three workout types per week (or every 10 days at lower volumes). These are the sessions that actually move the needle — the rest is supportive easy running.

Long run

Build progressively up to 22 km, run at easy pace (4:47–5:48 per km). This is the cornerstone session — never skip it, never race it. The point is time on feet at low intensity, not speed.

VO2max intervals

Example: 6×800m at interval pace (3:46–3:51 per km), with 90-second jog recovery between reps. Builds aerobic ceiling and running economy. Once per week, never in back-to-back days.

Threshold / Race-pace tempo

20-40 minutes continuous at threshold pace (4:06–4:17 per km), or progressive long runs ending at goal pace (4:16/km). Builds lactate clearance and race-pace efficiency. The most race-specific session of the week.

Week-by-week plan

Every session, day by day. Expand a week to see it. Paces and durations are guidance — Coach Leo fine-tunes them to your real data and how you feel.

Common mistakes when targeting 1:30

These are the recurring errors we see in runners aiming for 1:30. Avoiding them is often the difference between PR and DNF.

  • 1.Running easy days too fast. Your easy pace should feel conversational (4:16/km is your race pace — easy is much slower). Running easy days at marathon pace burns you out without aerobic adaptation gain.
  • 2.Skipping the taper. The last 2-3 weeks of reduced volume are not 'rest' — they are when adaptation consolidates and glycogen restores. Adding miles in the taper is the most common pre-race mistake.
  • 3.Treating the long run as a competition. The long run builds endurance, not race-day capability. Keep it relaxed (slow side of easy pace). If you are 'spent' the day after, you ran it too fast.
  • 4.Stacking intensity to compensate for missed sessions. If you miss a session, let it go. Trying to 'make it up' next week by doubling intensity is the fastest path to injury at this level.
  • 5.Underestimating recovery between hard sessions. Plan at least two easy or rest days between intensity workouts (intervals, threshold, marathon pace). The 'cumulative fatigue' Hansons approach is the only exception, and it's only for advanced runners.

Frequently asked questions

How long is the 1:30 Half-marathon training plan?

This plan is 12 weeks long, structured in four phases (base, build, peak, taper). Most runners commit to 5-6 runs per week.

How many kilometers per week do I need to run for a 1:30 Half-marathon target?

Peak weekly volume is 50-70 km/week. Volume builds gradually from week 1 (around 60-70% of peak) and tapers 40-60% in the final 2-3 weeks.

What baseline race time should I currently be able to run before starting?

We recommend a recent 10K time of 42:00. This corresponds to a Daniels VDOT of 51 — the physiological starting point for a credible 1:30 attempt.

What should my target paces be for 1:30?

Goal race pace is 4:16/km. Easy runs at 4:47–5:48 per km, threshold runs at 4:06–4:17 per km. These paces are derived from Jack Daniels' VDOT methodology calibrated to your goal.

How long is the longest run in this plan?

The longest single run is 22 km. It typically falls 3-4 weeks before race day, before the taper begins.

What if I miss a session or get sick during the 12-week plan?

A 12-week plan has built-in tolerance. Missing 1-2 sessions every 3-4 weeks is normal and won't compromise the goal. If you miss a full week, drop one upcoming intensity session to absorb the gap. Coach Leo handles this automatically by restructuring the plan day by day.

How is this different from a generic training plan?

This page describes the reference framework. The Coach Leo version adapts every session to your real Strava data, your daily readiness, and your weekly schedule — easy runs slow down when you're tired, intensity shifts around your sleep, the plan reshapes around missed sessions.

Sources & methodology

This plan synthesizes principles from the four most widely-used marathon training frameworks. Each is rigorously documented and validated by decades of competitive use:

  • Jack Daniels' Running Formula (4th ed., 2014)
  • Pete Pfitzinger — Advanced Marathoning (3rd ed., 2019)
  • Hal Higdon — Advanced marathon programs

Coach Leo does not replace medical advice. Consult a sports physician before starting any new training plan, especially after an injury or extended break.
