Sub 20 Minute 5K Plan

Sub-20 5K Training Plan

For runners who already have an aerobic base and want to break 20 minutes.

This isn’t a beginner plan. It assumes you can run continuously and comfortably, and it’s built to turn that base into speed over 10 weeks. Pace work starts from week 3, not week 7, because you’ve already earned the fitness that makes pace training useful rather than risky.

The plan moves through tempo runs, threshold intervals, and race-pace work at 4:00/km, building toward a race week built around one goal: an even, controlled 5K, not a number you haven’t earned yet.

What’s included:

• 10-week structured plan, 3 sessions per week
• Progressive tempo, threshold, and interval sessions
• Clear guidance on adjusting pace to your own fitness
• Built-in taper and race week

Best for: Runners already comfortable running 30+ minutes continuously who want a structured path to sub-20, not a start-from-scratch programme.
