How long should my plan be?

Explainer 1 min read Updated 6 October 2026

Short answer

Long enough for the goal and your starting point: a first 5K from scratch often takes around nine weeks, a marathon several months. Every plan ends on a date you choose, from two weeks to a year away.

Key points

  • Every plan ends on a date you choose.
  • Between two weeks and twelve months away.
  • If the date is tight, the plan's summary says so.

It depends on the goal

Building a running base, settling a sleep routine and preparing for an exam all have different natural timescales. The guide for each plan explains what is realistic.

A short runway

If your date is close, the plan builds more cautiously and its summary tells you honestly whether the goal fits.

Long goals

For a target a long way off, a longer plan leaves room for gradual progress and lighter weeks.
