Interval Training for Runners

Interval training is a fantastic (and essential) way to improve your running times regardless of your race distance; interval training will give you massive benefits come race day whether you are running 3k or a half marathon.

This post is taken from our extensive guide on how to train for a half marathon, however, as we have said, the principal of interval training can be applied to any distance.

 

So, Why Interval Training?

You need some speed in those legs!

When training for any race event  you should look at two types of interval training in order to help you achieve your best possible time.

Tempo Runs

Include interval runs within your long distance runs, shown previously, so that you get used to having spells of running faster during a long distance training run, otherwise known as tempo runs.

For example, you may be on a 5-6 mile run and within this distance you could include 1-2 miles at just below your actual race pace i.e. take the first 2 miles slow and steady, then run the next two miles slighter quicker than the pace you want to do on race day, finishing with a slow and steady last two miles.

For this type of training you need to know what pace you are aiming for on race day of course; let’s say that your race day pace is going to be 8 min/mile then your slow and steady pace for this particular training run could be 8.5min/mile.

You can split it up another way as well by running 1 mile slow and steady (eg 8.5min/mile) and then 1 mile at just under race pace of 8min/mile repeating this for 6 miles. So, the principle remains the same, you just set your pace according to where you are with your training.

If you don’t know what your fastest pace is you can very easily find out:

Find a fairly flat route around your local park or area and measure out 1 mile ( a lot of parks now have 100/200mtr posts or you can us a running app on your phone). Once you have warmed up, run that mile as fast as you can and I mean as fast as you can, so that you can barely breathe at the end! Record the time and you now have your fastest mile time; you can work everything else out from this fastest time.

 

Specific Interval Runs

You can also include specific speed sessions as part of your overall training.

So, for your speed interval sessions, as with all training sessions, you need to warm up correctly and then run to your park/running track so that when you start your speed intervals you are nicely warmed up. There are many combinations to choose from for speed interval work, and I have selected a few here that you might like to try:

 

Distance/TimePaceFrequencyNotes
2min on/ 2min offOn : faster than race pace

Off : jog

6-8 timesMaintain same “faster than race” pace every 2 mins on
400m on/ 400m offOn : faster than race pace

Off : jog

6-8 timesMaintain same “faster than race” pace every 400m on
3 min on/ 1 min offOn : faster than race pace

Off : jog

5-6 timesMaintain same “faster than race” pace for every 3 mins
200m/400m/600m/

800m/1km/800m/ 600m/400m/200m

Each leg to be much faster than race paceOnce, 60 secs recovery after each legAim to maintain “much faster than race” pace for each leg

 

So, in summary, you should aim to do one speed session every week and it can either be:

  • In the form of a tempo run within one of your long distance runs

      Or

  • A specific speed interval session on it’s own
