What you need
Steps
Set your target pace first. A sub-20 5K means running 4:00 per kilometre, or about 6:26 per mile, so every session is built around that number.
Warm up for 10 to 15 minutes of easy jogging, then add 4 or 5 short strides to wake up your legs before the hard work.
Run the main set: 5 x 1 km at 4:00 per kilometre, with 90 seconds of easy jogging between each rep.
Check your splits after each rep. Aim for even pacing rather than a fast first rep you cannot hold.
Build the rest of your week around the session: easy runs, one longer run, and at least one full rest day.
Keep one speed session in your week every week. Speed work is what raises your ceiling, easy running alone will not get you there.
Rehearse race day in training. Wear the kit and shoes you plan to race in and practise your start, pacing and finish.
Finish the last rep strongly, then cool down with 10 minutes of easy jogging and note how the session felt.
Tips and common mistakes
Keep easy runs genuinely easy so you have energy for the hard session.
If you cannot hold 4:00 per kilometre for all five reps, build your weekly distance for a few weeks before adding more speed.
Build mileage gradually and take rest days, since most running injuries come from doing too much too soon.
Practise your race pace in training so the effort feels familiar on the day, not like a surprise.
Questions
What pace is a sub-20 minute 5K?
You need to average 4:00 per kilometre, which is about 6:26 per mile. That is roughly 12.5 km/h on a treadmill.
How long does it take to get there?
Most runners need a block of consistent training, often 8 to 12 weeks, depending on where their current 5K time sits.
Can a complete beginner run a sub-20 5K?
Not straight away. You need a base of regular running first, usually a 5K time in the low 20s before this pace becomes realistic.
