Who it's for

You are new to running, or starting again after a long break. It is built to help you run a faster 5K.

Volume stays moderate with plenty of variety, which suits younger runners.

How the weeks work

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

If life gets in the way you can stretch it to 14 weeks, or tighten it to 8 if you are already fit.

The last 7 days are a taper: less running, a little intensity, so you start the race fresh.

  • Easy runs make up most of the week. Keep them slow enough to talk in full sentences.
  • Strides after some easy runs: four to six relaxed 20-second pickups with a full walk back.
  • Hill repeats: run up at a strong effort, jog back down, repeat.

Setting your paces

Start with a 5K time trial. Your result sets the paces for the rest of the plan, so run it honestly and on fresh legs.

Making it stick

  • Repeat a week if it felt hard. Moving on too early is the most common way to get hurt.
  • Walking is part of the plan, not a sign you are doing it wrong.
  • Soft, flat routes are kinder on your legs while they adapt.
