2:20:00 half marathon: what it equals and how to train for it

Running a half marathon in 2:20:00 means holding 6:38 per kilometre (10:41 per mile). Here is what that fitness is worth at other distances, and the paces to train at.

Equal race times

Predictions from an equal-effort model: the time you could run at each distance with the same fitness and the right training. Longer distances need specific endurance work.

RunPer kmPer mileWhat it is for
Easy7:16 to 8:1911:42 to 13:23Most of your running: conversational, builds the base.
Marathon6:4910:57Steady, controlled race-effort running.

Interval5:519:25Hard repeats of 3 to 5 minutes with jog recoveries.
Repetition5:318:53Short, fast repeats with full recovery, for speed and form.

How to use these numbers

  • Run most of your weekly distance at the easy pace. If you can only speak in short sentences, slow down.
  • Keep threshold and interval work to a small share of the week, and add it gradually.
  • Hot, hilly or windy? Judge hard sessions by effort, not pace.
  • Re-check your numbers after a new race or a hard time trial: fitness changes, and so should your paces.
