Running for beginners: how to start and stay injury-free

Most people quit running in the first few weeks, either because they started too hard and felt awful or because a sore shin forced a break. The fix is a slow start that mixes short runs with walking, three sessions a week with rest days in between, and a pace you can sustain. Here is how to build that habit, what to do about common aches and when to check with a clinician first.

In short

  • Start by alternating short runs with walking instead of running nonstop.
  • Run three times a week with rest days in between, and build up slowly.
  • Use the talk test to set your pace: you should be able to speak, not gasp.
  • Wear running shoes that support your feet and feel comfortable.
  • Stop and get help for pain, extreme shortness of breath or dizziness during a run.

Why a slow start matters

MedlinePlus advises building your activity up slowly so that you do not push too hard all at once. The NHS shin splints page explains why: starting to exercise after a period of inactivity is a risk factor for putting too much stress on the leg, as are running or jumping on hard surfaces and poor running technique.

If you struggle at first, that is normal rather than a sign you are unfit for running. The goal in the first weeks is to make running a regular habit, and speed can wait.

A beginner plan: run-walk intervals

The NHS Couch to 5K program is a free plan that takes you from not running to running 5 kilometers in 9 weeks. Its structure is a good template:

  1. Three runs a week.Leave rest days between runs.
  2. Mix running and walking.Each session alternates the two. Week 1 starts with 1-minute runs, each followed by a 1 minute 30 second walk.
  3. Build gradually.Runs get a little longer each week, building up to 30 minutes of continuous running by the end.
  4. Go at your own pace.You can take 9 weeks or longer, and you do not need to keep up with anyone else.
  5. Repeat a week if you need to.Falling behind your plan is better than getting hurt.

Pace: use the talk test

The CDC describes a quick check. At a moderate intensity you can talk but not sing. At a vigorous intensity you can say only a few words before you need to pause for breath. Beginners often run too hard, and if you are getting only a few words out, slow down or walk.

Adult guidelines are 150 minutes a week of moderate activity or 75 minutes of vigorous activity, or a mix, plus muscle-strengthening activities on at least 2 days a week. The CDC says the weekly total does not have to be done all at once. Strength work for all major muscle groups, especially the core, is one of MedlinePlus's recommendations for staying injury-free.

Shoes and equipment

  • Wear running shoes that support your feet. The NHS also suggests a supportive bra if you need one.
  • Pick comfort over claims, since a shoe should feel right from the first run.
  • Choose soft ground, such as a trail or track, over concrete where you can. The NHS lists hard surfaces as a risk for shin pain.
  • Dress for the weather and protect yourself from the sun.
  • If safety is a concern, pick a well-lit or busy location, and take care around traffic and in the dark.

Common aches: shin pain

Shin splints cause pain and tenderness along the front of the lower leg, usually during exercise such as running. According to the NHS, they usually improve within a few weeks, and the advice is:

  • stop the activity that caused it and build your routine back up slowly;
  • switch to gentle exercise such as swimming or yoga while healing;
  • use an ice pack wrapped in a towel for up to 20 minutes every 2 to 3 hours;
  • ask a pharmacist about pain relief that is safe for you;
  • warm up before you run, stretch afterward and use supportive shoes.

If the pain is getting worse or is not improving despite self-care, see your clinician. Call 911 or go to an emergency department if the pain is severe after an injury to your shin.

Who should check with a doctor first

The NHS says to speak to a clinician before starting if you are worried about your health. MedlinePlus advises checking first especially if you have trouble moving or balancing, if you are unsure whether exercise is safe for you, or if you have not exercised in a while. Mention any heart or lung condition, high blood pressure or diabetes, and tell your clinician about chest discomfort, unusual breathlessness, dizziness or fainting with effort before you begin.

Red flags: stop and get help

MedlinePlus says to stop exercising and get help right away if you have pain, extreme shortness of breath or dizziness, or if you do not feel right. Call 911 for chest pain or pressure, fainting, a racing or irregular heartbeat that does not settle, or sudden weakness or trouble speaking.

See a clinician promptly for pain that keeps getting worse, for pain that makes you limp or for any joint swelling.

Questions to ask your clinician

  • Is running safe for me, given my health and medicines?
  • Do I need any checks before I start?
  • How should I handle blood pressure or blood sugar around exercise?
  • What should I do about pain in my shins or knees?
  • Would a physical therapist help me build strength first?

Questions and answers

How fast should a beginner run?

Fast enough to move, slow enough to talk. If you can speak but not sing you are at a moderate effort, and if you can only say a few words you are working vigorously.

Can I run every day when I start?

It is better not to. The NHS plan has you run three times a week with rest days between, which gives your legs time to adapt.

Do I need special shoes?

You need running shoes that support your feet and feel comfortable. The NHS does not suggest anything more complicated for a beginner.

What if I cannot finish a session?

Walk more, shorten the run and repeat the week. The NHS says you can take longer than 9 weeks if you prefer.

Does running count toward the weekly activity guideline?

Yes. The CDC lists jogging as a vigorous activity, and 75 minutes of vigorous activity counts the same as 150 minutes of moderate activity.
