Sub 5k Training Plan Components

Breakeven Sessions – Sub 20 5k training plan

These sessions are used for maintaining fitness & recovery. Preparing you for breakthrough sessions:

  • Easy/ Steady Run – this run should be according to how you feel, don't worry about the time, make sure it's no quicker than 08:25 p/m. Concentrate on recovery and form.
  • Long Run – slow & steady run, this should be less than 1 hour.
  • Fartlek – unstructured training. Example Fartlek sessions.

Breakthrough Sessions – Sub 20 5k training plan

These sessions are meant to be challenging intense efforts, treat them as mini-milestones towards your target:

  • 400m Reps – these need to be at 6:15 p/m pace (93s per lap) with a 60sec standing recovery.
  • 800m Reps – should be reps at 6:25p/m pace (3:12 per 800m) with a 200m jogged recovery.
  • 1km Intervals – hit 6:25p/m pace (4:00 per km) with a 90sec jogged recovery.
  • Hills: Kenyans/ Hill Sprints – alternate between Kenyans and Hill Sprints to get a balance of power and endurance training. Example Hill Training Sessions.

About this Sub 20 minute 5k Training Plan

Remember that to consider following this sub 20 minute 5k plan you should already be able to run at a target race pace of 6:25 for at least a mile (3:59p/km) and/or have a PB under 22 minutes.

The core work for the sub 20 5k training plan is set over a 3-week period with the addition of 1 week’s recovery. At the end of the first 4-week cycle you can repeat and/or tailor the plan to your individual needs to focus on your particular 5k event.

It is recommended that after three months following the sub 20 5k plan that you reduce your training for a period of one to two weeks to allow your body time to recover from the impact of running. This should mean more time cross-training with a couple of nice easy runs every few days to keep the legs ticking over.

    Thanks Matt,what pace and incline would you recommend on the treadmill when doing the hill/s workouts?

  2. Murray says:

    Thanks Matt, will give it a try end of month, what paces and incline would you recommend for the hill sessions on the treadmill?

  3. Murray says:

    Can this plan be done on the treadmill?

    • Matt says:

      Hi Murray, the speed interval elements are often best achieved on a treadmill as easier for pacing but I would be wary of doing too much mileage on a treadmill. My recommendation would be to complete the breakthrough sessions on a treadmill but try and get outside for the recovery/long runs as much as possible. Good luck!

  5. Martin says:

    Chuffed. Thanks.

  6. Lawrence says:

    Thanks for the training plan. Was running around 21/22 and after six weeks enjoyed a relaxed 19.55. At 45 was pleased with progress and as a 400m runner at heart running a strong 5k was great. Thanks again
