How a half marathon should train

Efficient, strong and durable over your distance.

The short answer

A half marathon should build aerobic capacity and runner's strength, and practise pacing and form. The drills that matter most are cadence work, strides, pacing ladder. 5 of them need nobody but you.

⚡ Prioritise physically

  • Aerobic capacity
  • Runner's strength
  • Economy

🎯 Sharpen technically

  • Pacing
  • Form
  • Fuelling

Key exercises

Tempo runs

Extends your aerobic base so you repeat sprints late in games.

Hill sprints

Low-impact way to build sprint power and drive mechanics.

Single-leg RDL

Bulletproofs the hamstring and trains single-leg balance.

Standing calf raise

Stiffer, stronger calves protect the Achilles and add spring.

Technical drills for a half marathon

5 of these need nobody but you.

Cadence work

TechniqueOn your own

Setup: A watch or metronome and an easy route.

  1. 1. Run 5 minutes at your normal cadence and count your steps.
  2. 2. Run 5 minutes at roughly 5% more, taking shorter steps at the same pace.
  3. 3. Alternate for the session.

Volume: 6 × 5 minutes, alternating

Coaching point: Shorter steps, not faster running. Overstriding is braking with every step.

Make it harder: Hold the higher cadence for longer blocks until it stops feeling deliberate.

Strides

SpeedOn your own

Setup: 80–100m of flat ground, after an easy run.

  1. 1. Build smoothly to about 95% over the first 40m.
  2. 2. Hold relaxed at that speed for 20m — face loose, shoulders down.
  3. 3. Decelerate gradually over the last stretch. Walk back.

Volume: 6 × 80m, walk-back recovery

Coaching point: Fast and relaxed, not fast and straining. Clenching your jaw slows you down.

Make it harder: Add a stride or two, or put them on a slight downhill for overspeed.

Pacing ladder

PacingOn your own

Setup: A track or a measured route, and a watch.

  1. 1. Run 400m at marathon pace, then 400m at half pace, then 400m at 10k pace.
  2. 2. Check the watch only at the end of each rep, not during it.
  3. 3. Note how far off you were — that gap is the skill.

Volume: 3 rounds, 90 seconds between

Coaching point: Pacing is a feel you build, not a number you read. Guess first, verify after.

Make it harder: Cover the watch entirely and estimate each split before looking.

Downhill control

TechniqueOn your own

Setup: A gentle 4–6% descent, 100m long.

  1. 1. Lean very slightly forward from the ankles, not the waist.
  2. 2. Increase your cadence rather than reaching with your stride.
  3. 3. Land underneath yourself, quiet feet.

Volume: 6 × 100m, jog back

Coaching point: Reaching downhill brakes on every step. That's what wrecks quads late in a race.

Make it harder: Slightly steeper, or hold the control for longer descents.

Breathing rhythm

BreathingOn your own

Setup: An easy run.

  1. 1. Settle into breathing in for three steps and out for two.
  2. 2. Hold that pattern for five minutes, then switch to two-in two-out at a harder effort.
  3. 3. Return to easy and re-establish the three-two.

Volume: 3 × 5 minutes

Coaching point: An odd-numbered pattern alternates which foot you exhale on, so one side doesn't take every impact at full exhale.

Make it harder: Hold the rhythm at progressively harder efforts.
