4 Week Half Marathon Training Plan

GSRsupergirlIt’s the Great Scottish Run in 4 weeks time (6th October), where thousands of people will run a 10k and half marathon as part of the big event in Glasgow.  Someone in work was asking if I thought he could train to run the half marathon in just 4 weeks.

He’s trained for and run half marathons before, but he’s recently had 6 weeks off running. I’m thinking, of course you can!

4 Week Half Marathon Training Plan

With this in mind, he (and you) could easily do the following to aim to do a half in 4 weeks:

Mon Date


Run 1

Run 2

Long Run



4 (e)

5 (in)




4 (e)

5-6.2 (in)




4 (e)

5 (in)




5 (in)

4 (e)


(*Distances in miles)

3 runs a week, ideally alternating with rest days between.
( e )  – 1 Easy run,
( in ) – 1 Intense run: intervals / hill work / time trial (or easy)  ( in )
         – 1 Long run (build up mileage weekly, long runs always followed by a rest day)

Ideas for intervals / effective workouts:
(choose one a week, or do an easy run instead):
– 45 mins Intervals: 10 min warm up, 12 x 1:1 fast: recover, 6 mins recovery
– 10k time trial – see how fast you can run 10k in
– 45 mins Intervals: 10 min warm up, 4 x 3:3 fast: recovery, 6 mins recovery
– 45 mins Intervals: 10 min warm up, 6 x 2:2 fast: recovery, 6 mins recovery
– 45 mins Hills: 10 min warm up, 25 mins hills, 10 mins recovery

In each 45 minute interval session you should aim to run FURTHER than the last time.(**Time in minutes)

If the worst comes to the worst, you could train for and do the 10k (with 4 weeks training), but with the training plan above, you should be able to easily train for and complete the half marathon.

    Lorn, I’m not understanding what you mean by 12 x 1:1 or 4 x 3:3 or 6 x 2:2 – would you mind explaining please? Ally

    • lornpearson says:

      Sure Ally. 12 x 1:1:
      You warm up for 10 mins.
      Then you run for 1 min fast.
      And you recover for 1 min (walk or jog slowly).
      You do this 12 times.
      Then you cool down for 6 mins.

      Does that make sense?
      (4 x 3:3 is 3 mins fast, 3 mins recovery 4 times etc)

  2. Ally Robb says:

    Thank you for explaining this – it makes sense now.
