How to start
running from scratch

Without getting injured and without quitting in week three. Seven steps and an 8-week plan to go from the couch to your first 5 km.

Starting to run is one of the most rewarding decisions you can make for your health, and all you need is a pair of shoes and a bit of common sense. The problem is rarely a lack of willpower — it's starting badly: too fast, too many days, too soon. That's how you end up sore, niggling and, by week three, quitting.

This guide walks you step by step through how to start well and, above all, how not to stop. At the end there's a free 8-week plan that puts all of this in order, session by session.

First of all

Start here

Set a real goal and picture it

Before the first stride, decide where you want to get to: your first non-stop 5 km, or a specific local race. A goal with a date and a name gives your training a shape and keeps you going when motivation dips. Many runners later hang the poster of their first race as a reminder of how far they came from zero.

Why it works: Starting without a concrete goal is the number-one reason people quit. A visible goal (a date, a distance, a race) turns 'going for a run' into a project with a beginning and an end.

The method that works

Alternate walking and running

Don't try to run 20 minutes non-stop on day one — that's the recipe for ending up exhausted and so sore you lose all desire to continue. Start by alternating, for example, 1 minute running and 2 walking, repeated several times. Week by week you increase the running and reduce the walking. Your body adapts without getting injured.

Why it works: The walk-run method is backed by decades of practice. It lets tendons, joints and heart adapt gradually — which is exactly what fails when someone 'goes for it' too fast.

Less is more

Three days a week, with rest in between

Running every day when you start doesn't make you better — it gets you injured. Three sessions a week, with a rest day between each one, is ideal for a beginner. Rest isn't wasted time: it's when the body rebuilds itself stronger.

Why it works: Beginner running injuries almost always come from doing too much, too soon. Rest is part of the training, not the opposite of it.

The golden rule

Always run at an easy pace

You should be able to hold a conversation while you run. If you're going so fast you can't talk, you're going too fast. Speed comes on its own over the weeks; at the start the only goal is for your body to learn to run, not to run fast.

Why it works: Almost every beginner runs too fast and gets frustrated. At a conversational pace, sessions are sustainable and you enjoy the process — which is what makes you come back.

Recommended

Follow a structured plan

Improvising works for a few weeks; a plan works every time. Our 'Couch to 5K' plan takes you from running nothing to completing 5 km non-stop in 8 weeks, with 3 sessions a week, all at an easy pace. We email it to you free as a PDF so you can print it and stick it on the fridge.

Why it works: A plan removes the daily decision of 'what do I do today'. You just follow the day's session. That simplicity is what sustains the habit until it becomes automatic.

Without overspending

Gear: less than you think

To start you only need running shoes that fit comfortably (not the most expensive model) and breathable clothing. No pricey watches or gadgets: those can come later if you want. The one thing worth investing in from the beginning is a good pair of shoes that protect your joints.

Why it works: Too much gear doesn't make you run more; sometimes the upfront cost even puts people off. Starting with little lowers the barrier and keeps you focused on what matters: going for a run.

The real secret

Consistency beats intensity

It's better to run 20 easy minutes three times a week for two months than to crush yourself one day and disappear for a week. Progress in running is slow but sure: if you're consistent, in two months you'll be running distances that seem impossible today.

Why it works: The body responds to repetition, not to heroic days. Consistency, not intensity, is what turns a couch dweller into a runner.

The most important advice

Don't run to exhaust yourself today, run so you can come back tomorrow. Consistency, not intensity, is what turns a couch dweller into a runner.

Frequently asked questions

How long does it take to start running from scratch?

With a progressive plan like 'Couch to 5K', in about 8 weeks you can go from running nothing to completing 5 km non-stop, training 3 days a week. The key is to start by alternating walking and running, gradually increasing the running time.

How many days a week should I run at the start?

Three days a week, with a rest day between each session. For a beginner, more days don't speed up progress: they increase injury risk. Rest is when the body adapts and gets stronger.

What pace should I run at if I'm starting from zero?

Always at an easy pace: you should be able to hold a conversation while running. If you can't talk, you're going too fast. Speed comes on its own over the weeks; at the start the goal is just to get your body used to running.

Do I need special shoes to start running?

You need comfortable running shoes, but not the most expensive on the market. They're the one thing worth investing in from the start, because they protect your joints. The rest of the gear (watches, advanced technical clothing) is optional and can wait.

Can I start running if I'm overweight or haven't exercised in years?

Yes. The alternating walk-run method is designed precisely for that: start very gently so the body adapts without injury. Begin with more walking than running and increase very gradually. If you have any medical condition, check with your doctor first.
