Running when overweight: a kind, joint-friendly way to start

You can start running at any size. The kindest way to begin is with brisk walking, then short bits of very easy running mixed with walking, two or three times a week, with a rest day between sessions. Go slowly, choose soft and flat ground, and wear comfortable shoes and clothes that don’t rub. Your body will adapt; it just needs a little time and patience.

Can you start running if you’re overweight?

Yes. Running isn’t reserved for one body type, and there’s no weight you need to reach first. What matters is how you start. Carrying extra weight means each step asks a bit more of your knees, ankles and feet, so the trick is to build up more gently than the usual plans suggest, and to give your joints time to get stronger along with your heart and lungs.

If you have a heart condition, high blood pressure, diabetes, joint problems, or you haven’t exercised in a long time, check with your doctor before you start. Most will be glad you asked.

Should you walk before you start running?

If 30 minutes of brisk walking doesn’t feel easy yet, yes. Walking builds the base that running sits on, with much less strain. Try this for two to four weeks:

• Walk briskly for 20 to 30 minutes, three times a week.
• Walk at a pace where you’re breathing a bit harder but can still talk.
• Once 30 minutes feels comfortable, you’re ready to add some running.

Walking is not a lesser version of running. It’s the first step of the same journey. In the Run app, being able to walk for 30 minutes is exactly where level 1 starts.

How do you start running gently?

Add tiny bits of running to your walks, keep them very slow, and grow them a little at a time. Here’s a gentle path:

Step	Each session (after a 5-minute warm-up walk)
1	Walk briskly 30 minutes, 3 times a week
2	Run 30 seconds, walk 2 minutes, 6 to 8 times
3	Run 1 minute, walk 2 minutes, 6 to 7 times
4	Run 2 minutes, walk 2 minutes, 5 to 6 times
5	Run 3 minutes, walk 1½ minutes, 5 times
6	Keep stretching the running bits as they feel easy

Stay on each step for at least a week, and longer if it still feels hard. There’s no deadline. Our guide to the run-walk method explains how to move up when you’re ready.

Run as slowly as you like. A gentle shuffle where your feet barely leave the ground counts as running and is much kinder on your joints than bounding along. If you can talk in full sentences, your pace is right. See how slow you should run for why slow is the secret.

How do you protect your knees and joints?

Go slowly, land softly and keep the volume low at first. Joint-friendly habits:

• Take short, quick, light steps instead of long strides. Try to land with your foot under your body, not out in front.
• Choose soft, flat surfaces: park paths, grass, a running track or a treadmill. Avoid steep downhills at first.
• Leave a rest day between runs. Your joints get stronger on the days off.
• Change one thing at a time: a little longer running, or an extra session, not both in the same week.
• Add some simple strength work. Sitting down and standing up from a chair slowly, 10 times, and calf raises holding a wall, twice a week, both help your legs cope.
• Treat pain as a signal. Normal muscle tiredness is fine. Pain that is sharp, gets worse as you run, makes you limp, or lasts more than a few days means stop, rest, and see a doctor or physiotherapist.

If your knees are already a bit grumpy, our guide to knee pain for beginner runners has more ideas.

What should you wear?

Wear shoes with a bit of cushioning that feel comfortable from the first step, and clothes that don’t rub. A few things make a big difference:

• Shoes: a running shop can help you find a comfortable, supportive pair. Our guide to running shoes for beginners explains what to look for.
• Anti-chafing: thighs, underarms and under the chest can rub. Running shorts or leggings that cover your thighs, plus an anti-chafe balm, solve most of it.
• A supportive sports bra, if you need one. It’s worth spending a little more here.
• Breathable fabrics that dry quickly instead of cotton, which stays wet and heavy.

You don’t need to buy everything at once. Comfortable shoes and something that doesn’t chafe are enough to start.

How do you deal with feeling self-conscious?

Start where you feel comfortable, and remember that nobody is watching as closely as you think. A few ideas that help:

• Run early in the morning or in a quiet park while you build confidence.
• Start on a treadmill at home or at the gym.
• Go with a friend, or join a beginner group where everyone is new.
• Use headphones and an audio coach, so your attention is on your own run.

Most runners are delighted to see someone new out there. A nod or a wave is about as much attention as you’ll get.

Will running help you lose weight?

Running can be part of it, but it’s best not to make weight the only measure of success. Running is wonderful for your heart, your mood, your sleep and your confidence, and those benefits start in the first few weeks, whatever the scales say. Weight depends on lots of things, including food, sleep and stress.

So celebrate the other wins too: the first time you run 5 minutes without stopping, the hill that used to feel impossible, the morning you actually look forward to a run. In the Run app, you rate how tiring each run felt, and if one was very hard, the next one gets lighter straight away, so you’re never pushed further than your body is ready for. You can read more on how it works.

Every runner you’ve ever seen started with a first, slow, slightly awkward run. Yours is no different.
