Who it's for

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

How the weeks work

It runs for 28 weeks with 5 to 6 runs in each.

If life gets in the way you can stretch it to 32 weeks, or tighten it to 24 if you are already fit.

The last 14 days are a taper: less running, a little intensity, so you start the race fresh.

  • Marathon-pace blocks inside some long runs, so goal pace feels routine by race day.
  • Intervals: repeats a little faster than race pace, with easy jogging in between.
  • A medium-long run midweek, around two-thirds of your long run.
  • One long run a week that grows slowly. Run it easy; the time on your feet is the point.

Setting your paces

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

Later benchmarks: a marathon-pace check run. 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.
