Couch to 5K builds from 1 minute runs to 30 minutes non stop over 9 weeks, 3 runs a week. Feeling out of breath at first is normal; it eases fast.

Stop and get help if you have chest pain, feel faint or are unusually breathless, and call 999 if chest pain does not go away. If you have a heart, lung or joint condition, check with your GP before stepping up.

The working

1 minute now, aiming for 20, 3 runs a week

The NHS Couch to 5K plan starts with 1 minute runs and reaches 20 minutes non stop at the end of week 5. If you can manage 1 minute now you would start around week 2, so it takes about 4 weeks at 3 runs a week.

The talk test

Easy is right

Go slow enough to talk in short sentences but not sing. Being out of breath at the start is normal and gets better within weeks.

Repeating weeks

Totally fine

  • Repeat any week that feels too hard
  • Walk breaks are allowed
  • Three runs a week with rest days between suits most people
