Who it's for

You run most days and are used to structured workouts. It is built around a specific 1 km time you want to hit.

How the weeks work

It runs for six weeks with 4 to 5 runs in each.

If life gets in the way you can stretch it to 8 weeks, or tighten it to 6 if you are already fit.

The last 5 days are a taper: less running, a little intensity, so you start the race fresh.

  • Hill sprints of 8 to 10 seconds up something steep, walking back down to recover fully.
  • Intervals: repeats a little faster than race pace, with easy jogging in between.
  • Easy runs make up most of the week. Keep them slow enough to talk in full sentences.

Setting your paces

Start with a 600 m time trial. Your result sets the paces for the rest of the plan, so run it honestly and on fresh legs.

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.
  • Keep strides in the week even when you are tired; they are what keep you sharp.
