1:50:00 half marathon: what it equals and how to train for it

Running a half marathon in 1:50:00 means holding 5:13 per kilometre (8:23 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.

Training paces for this fitness

RunPer kmPer mileWhat it is for
Easy5:48 to 6:419:21 to 10:45Most of your running: conversational, builds the base.
Marathon5:248:41Steady, controlled race-effort running.
Threshold5:038:08Comfortably hard: tempo runs and cruise intervals.
Interval4:397:29Hard repeats of 3 to 5 minutes with jog recoveries.
Repetition4:237:03Short, 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.
