Who it's for

You run most days and are used to structured workouts. It is built around a specific half marathon time you want to hit.

How the weeks work

It runs for 16 weeks with 5 to 6 runs in each.

If life gets in the way you can stretch it to 22 weeks, or tighten it to 14 if you are already fit.

The last 12 days are a taper: less running, a little intensity, so you start the race fresh.

  • Blocks at your goal race pace, so it feels familiar when it counts.
  • Threshold runs of 15 to 30 minutes at a comfortably hard pace. You could say a few words, not hold a conversation.
  • A medium-long run midweek, around two-thirds of your long run.

Setting your paces

Start with a 10K time trial. Your result sets the paces for the rest of the plan, so run it honestly and on fresh legs.

Later benchmarks: a half-marathon pace check. Use them to adjust your paces rather than to chase a number.

Making it stick

  • Protect the key sessions. The easy running around them can move.
  • Compare each benchmark with the last one and adjust your paces, up or down.
  • Practise your race-day fuelling on long runs, not on race day.
