Who it's for

You run most days and are used to structured workouts. It is built around a specific 5K time you want to hit.

How the weeks work

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

If life gets in the way you can stretch it to 10 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.

  • Intervals: repeats a little faster than race pace, with easy jogging in between.
  • Blocks at your goal race pace, so it feels familiar when it counts.
  • 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 3 km time trial. Your result sets the paces for the rest of the plan, so run it honestly and on fresh legs.

Later benchmarks: a 5K time trial. 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.
  • Keep strides in the week even when you are tired; they are what keep you sharp.
