How to start running: a beginner's guide
By the Kiki team · Updated · 6 min read
Start with run/walk intervals three times a week, such as 1 minute of easy running and 90 seconds of walking, repeated for 20 to 30 minutes. Keep the pace conversational, rest between runs, and add a little more running each week. Most beginners can run 30 minutes non-stop within 8 to 10 weeks.
What you need
Less than you think. A pair of comfortable running shoes, clothes you can move in, and 30 minutes three times a week. Fancy watches and gels can wait.
- Shoes that feel comfortable from the first step, with about a thumb's width of space past your longest toe.
- A safe route: a park loop, a track or quiet streets.
- A plan, so you know what to do each day instead of guessing.
Your first week
Begin every session with 5 minutes of brisk walking. Then alternate 1 minute of easy running with 90 seconds of walking, eight times. Finish with a few minutes of walking. That's it. Do this three times in the week, with a rest day between sessions.
Coach's tip: Walk breaks aren't cheating. They let you run more in total, with less strain, and they're how most beginners build up safely.
How fast should you run?
Slower than you think. Use the talk test: you should be able to speak in full sentences while you run. If you can only get out a few words, slow down or walk. Speed comes later. Early on, the goal is simply to finish each session feeling like you could have done a bit more.
How often to run
Three runs a week is the sweet spot for most beginners. Your muscles, tendons and bones adapt during the rest days, not during the run itself, so rest days are part of training.
How to progress
Each week, run a little more and walk a little less. A typical progression goes from 1-minute running intervals to 3, then 5, then 8, until you can run 20 to 30 minutes without stopping. If a week feels hard, repeat it. There's no prize for rushing.
| Weeks | Running | Walking | Repeats |
|---|---|---|---|
| 1–2 | 1–2 min | 90 sec | 6–8 |
| 3–4 | 3–5 min | 90 sec–2 min | 3–5 |
| 5–6 | 8–10 min | 2 min | 2–3 |
| 7–8 | 20–30 min | None | 1 |
Common beginner mistakes
- Running too fast. It makes every run feel hard and raises your injury risk.
- Doing too much too soon. Adding a lot of running in one week is the most common path to shin pain and sore knees.
- Skipping rest days. Back-to-back hard days leave you tired, not fitter.
- Quitting after one bad run. Everyone has them. The next one is usually better.
Before you start
If you have a heart condition, a recent injury, are pregnant, or haven't exercised in a long time, check with a doctor first. Mild muscle soreness is normal in the first weeks. Sharp pain, or pain that gets worse as you run, is a sign to stop and rest.
Common questions
- How long does it take a beginner to run 5K?
- Most beginners can run 5K (3.1 miles) without stopping within 8 to 10 weeks, running three times a week with run/walk intervals that gradually become continuous running.
- Is it okay to walk during a run?
- Yes. Planned walk breaks help beginners run more in total with less strain. Many experienced runners use them in long runs and marathons too.
- Should I run every day as a beginner?
- No. Three runs a week with rest days in between is enough to improve steadily. Rest days are when your body adapts and gets stronger.
