FOUR STEPS FOR A FIRST RUN
These steps come from the NHS's Couch to 5K programme and its advice on warming up and avoiding running injuries.
The NHS says it is important to buy the correct running shoes, and best to go to a running shop to get fitted.
The NHS warm-up routine takes at least 6 minutes: marching on the spot, heel digs, knee lifts, shoulder rolls and knee bends.
Couch to 5K uses three runs a week with rest days in between, starting with 1-minute runs and 90-second walks.
Do not increase the intensity or distance too quickly, and do not run if you are in pain.

THE BEGINNER'S PLAN

The NHS Couch to 5K programme guides people from the couch to running 5km in 9 weeks, and it can also be done over a longer period. The NHS says it is for everyone, no matter your fitness level, and has helped millions of people.
Common running injuries the NHS names include runner's knee, Achilles pain, shin splints, heel pain and hamstring or calf strains. Its prevention advice: the correct shoes, a proper warm-up, a gradual build-up and rest when you are in pain.
