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

  3. James says:

  4. Vítor Caldeira says:

  5. Olivier says:

    PB was 22:00 on the 5k. Did 2 months of this programm (about 5-6 weeks of the actual training, because 6x a week was too much for me) and I scored a 19:18 on my 5k race yesterday. Thanks !!

  6. Julez says:

    Thank you for putting together these plans. I’m sincere between the 22 and sub 20 plan right now so I’ve combined the two plans and averaged the set times to make the workouts challenging, but not kill me.

    The one thing you mention is the 1hr max distance runs. I’m a half marathon runner who is also trying to improve their 5k time since those are the most popular races. I generally run 13 miles every weekend (1hr:50min)ish and stick to 3 days a week of 5k training with two strength training days.

    Do you feel this could be overtraining since I’m throwing in the longer distance? How would you change the 5k training plan for someone who doesn’t want to give up a longer run each week?

    • Nathan says:

      I am in much the same training place as you are. I typically tend to be injury prone too. So what I’ve done is alternate, running a little over 1 hr, about 7-8 miles one week and then a longer 11-13 the alternate week for my long runs
