Improve Your 5K Time

Already running 5K? This 6-week speed plan will help you smash your personal best with structured speed work.

Intermediate

Overview

You can run 5K — now let's make it faster. This 6-week plan introduces structured speed work to improve your 5K time. Expect to shave 1–3 minutes off your PB (personal best).

Prerequisites: You should be running 5K at least twice per week before starting.

New to speed work? This plan uses tempo runs (sustained "comfortably hard" pace) and intervals (short, fast bursts with recovery). If these terms are unfamiliar, read our Interval & Tempo Training guide first — it explains everything.

What Makes You Faster

Training Element Why It Works
Intervals (400m–1km) Improves VO2max (your body's maximum oxygen capacity) and running economy
Tempo runs Raises your lactate threshold (the point where your muscles start to fatigue rapidly) — you can hold a faster pace for longer
Long easy runs Builds aerobic base and endurance
Rest days Where the actual adaptation happens

Race Day Strategy

  1. Don't start too fast — first km should feel easy
  2. Settle into pace — km 2–3 at target pace
  3. Push from km 4 — this is where you dig in
  4. Sprint the last 400m — empty the tank
